NASA: One-third of gamma ray sources are complete mysteries

The Fermi Space Telescope has detected 1,873 gamma ray sources in space, and nearly 600 are complete mysteries, NASA wrote today on its website.

NASA's Fermi team has recently released the second catalog of gamma ray sources from its satellite's Large Area Telescope and have no idea where nearly one-third of gamma rays originated.

"Fermi sees gamma rays coming from directions in the sky where there are no obvious objects likely to produce gamma rays," said David Thompson, Fermi deputy project scientist, of Goddard Space Flight Center in Maryland.

Gamma rays are a "super-energetic form of light produced by sources such as black holes and massive exploding stars," according to NASA.

Researchers say two-thirds of the gamma rays come from objects such as pulsars or blazars. The remaining third are a complete mystery right now.

Researchers are speculating on the nature of the mystery sources, including the possibility that they are made of dark matter.

"Some of the mystery sources could be clouds of dark matter, something that's never been seen before," Thompson said.

NASA explains that about “85% of the gravitational mass of the universe is dark matter,” and “the stuff we see makes up the rest.”

“Dark matter is something that pulls on things with the force of its gravity but can't be detected in any other way. It doesn't shine – doesn't emit or scatter light – hence the adjective ‘dark,’ ” NASA writes.

Astronomers cannot detect dark matter directly using optical or radio telescopes, but researchers think dark matter just might shine in gamma rays.

"We've been using Fermi to search for dark matter for a long time," said Peter Michelson of Stanford University, the principal investigator for the Large Area Telescope.

So why do researchers think the source could be dark matter?

"Some researchers believe that when two dark matter antiparticles bump into each other, they will annihilate, producing gamma rays. Concentrated clouds of dark matter could form a gamma ray source at specific wavelengths detectable by Fermi," NASA explains.

"If we see a bump in the gamma-ray spectrum – a narrow spectral line at high energies corresponding to the energy of the annihilating particles – we could be the first to 'apprehend' dark matter,” Michelson said.

Researcher point out that there are other possibilities for the mystery sources, including colliding galaxy clusters or some type of new phenomenon, such as something involving galactic black holes.

The Fermi team plans to continue observing the mystery sources.

"Of course we're hoping for something really exotic like dark matter, but we have to look first at all the other options," Thompson said. "Fermi is an ongoing mission. We'll continue to search for answers to these puzzles and perhaps turn up even more surprises."

    I didn't read the article yet, but knew that there would be some moron trying to pull god into the picture...sure enough when I did a search on the word "god" there were more than 50 matches.

    Stop with the god crap. None of us want to hear about it. Prove your god exists or STFU about it.

      Dude, take a chill pill, Phil! I believe in God but I also believe things happened the way scientists say it did. It's not a far stretch to believe in both. Besides, you tell people to prove God exists or to "STFU". Prove he DOESN'T exist...or....STFU. Double edge swords cuts in both directions. I like the article though!

    It is factually incorrect to state unequivocally that "85% of the gravitational mass of the universe is dark matter".
    That is actually a fringe hypothesis for which there are more contraindications than anything else.
    A correct revision would be "Our mathematical models have such poor fidelity for macro-gravitational behaviors, that their predictions can account for only 50% of the observed data, leaving the other 50% of data unattributable to anything except pure fn magic ... unless our models are wrong."
    The limitations of our models do not obligate the existence of extraordinary amounts of an exotic and completely unprecedented substance. Extraordinary claims require extraordinary proof.
    Pseudoscience is alive and well at NASA.

      well, that's exactly what we mean, we don't know and it's not accounted for by something we observe. dark matter and energy are just names describing something we know has to exist but not a clue about what it is or how it works

    of course they don't know where the gamma rays are coming from, just like they reconcile einsteins theory and quantum mechanics with string theory..oh i've got an idea, everything is held together with string...give me a break.

      I'm pretty sure that you don't know anything about String Theory. It's pretty complex, and is almost certainly not the right answer, but at least learn something about it before bashing it, eh?

    • Jeff

      oh dear god please show me where in String theory it says the world is held together with String... that would be so awesome.

      String theory mainly posits that the electrons and quarks within an atom are not 0-dimensional objects, but rather 1-dimensional oscillating lines ("strings"). The earliest string model, the bosonic string, incorporated only bosons, although this view developed to the superstring theory, which posits that a connection (a "supersymmetry") exists between bosons and fermions. String theories also require the existence of several extra, unobservable dimensions to the universe, in addition to the four known spacetime dimensions.

      There is a very very very basic intro concept into String theory... Please for the good of humanity and the advancement of the human specie please stop spreading the disease that is stupidity.

    With all military spending to guarantee the flow of oil to the corporations, there is not a lot of money left for NASA. Also, the US sends 3 Billion dollars/year to little Israel to help on its safety, as long as they don't have nuclear capability. The US sends 2 Billion dollars to Egypt to make sure the generals protect the Israelis against the angry Egyptian population.
    Can you imagine how much money the US would be able to use internally, including NASA, if they completely disengage from the Middle East?

    October 19, 2011 at 12:10 pm |
    • BBoy705

      Hey Johnny, I could not agree more! Of course Israel has nukes so they really don't need our help. The Arab Spring should be used as an opportunity to push the idea that peace is better for prosperity than war to countries like Egypt and doing so would get better results than paying off corrupt Generals in places like Egypt and Libya, etc. With the savings NASA could be funded the way it should be. Certainly everyone reaps more benefit from scientific research than from waging war or supporting discord!

      I agree totally. Isreal has nukes and does what it wants. I don't see that they need us. The Egyptians are the same. You will never work out a peace plan until all the bottom is reached. they should duke it out until the are fed up with all of thier crap.

Also, perhaps it's time for the US Reps to have a heart to heart chat with Russia, China, England, France, et. al., with regards to their current debts from World War 1 and 2...not to mention NATO which has eaten up tons of bucks since 1946. Get that monkey off our backs and we can rebuild this nation while still keeping a viable standing army, navy, marine corps, air force, etc. to DEFEND our borders against the illegal immigrants and others who are costing us tons of money.

    Confucian scholar.. u can keep putting me down, that's cool I don't care. U must realize the rich 1% is controlling the world and are making life below what it should be for the other 99%. Sure there are a few who have made it rich and successful.. Whoo.. good for them. They r probably dead now and can't take their money with them. What did they accomplish here on earth is the question. To get rich taking advantage of others is no true way to achieve fullfillment out of life. The 1% are forcing everyone to use oil like there is Jo better alternative. Check out nikola tesla as the his inventions go unknown. Every 5 seconds a child dies because he can't get fresh water. Go ahead dude enjoy all the shit u got. Just remember millions die and live sad lives. Just because they don't have a voice and u don't see their face don't mean they don't exist. We are all one.

    Science is the foundation of the modern world and basic science works by exploring ALL areas of natural phenomenon, regardless of where they occur. Some posters argue we have more pressing needs on Earth, but what they don't realize is the answers can come from anywhere, including space. Don't forget the Sun is in space and without it Earth would not be habitable. Think about it this way, NASA has discovered that something we don't understand is creating the most powerful light known (gamma rays). If scientists can unravel how it is done, maybe that knowledge can be used someday by engineers to solve our power generation problems, who knows? I applaud NASA for this discovery because this is how science works and NASA is making science, and therefore us, that much stronger.

Good luck getting a decent job and living a normal life after that. See the govt./elitist want u to drink alcohol and smoke cigs.. sure go kill urselves and our urselves in the hospital and feed our biggest gdp producer, the healthcare system.

The top ten contributors are the same for both candidates last election just in different orders.. bank of America, Exxon mobile, shell, fannie Mae, Freddie MAC, clearchannel which runs all CNN fox and msnbc.. don't u all see there is no left or right. It's all the same news being sold to u at the top. Clearchannel filters ur news. If on the left u watch msnbc on the right u watch fox. Middle watch CNN. But they are all run by the same dude.

    Dark matter has become to science what god is to religion; the unprovable default explanation for anything we can't explain.

    October 19, 2011 at 11:33 am |
    • Joshua Ludd

      Of course the difference is the theoretical basis for dark matter which comes from what we know about matter and the universe in the first place... and the fact that unlike religion science basically uses things like dark matter and dark energy as place holders until they are more fully understood... and research is ongoing. To compare science to religion is to grossly misunderstand one if not both of the two.

      October 19, 2011 at 11:59 am |
    • JasonLinMT

      I agree with Mr. Ludd, religion is a closed case. The book of science is still being written. When religionists use God as an excuse for anything they can't explain, they have already given up trying to understand that idea, saying only that "God works in mysterious ways". When scientists can't explain something, relative only to such subjects as black holes or the expanding universe or mysterious gamma rays, they say "MAYBE it is due to dark matter, or maybe not." and continue to look for an answer, discovering more about our universe in the process, even if the question is never answered. Dark matter could be one thing, or 20 things all lumped together, and being used as a placeholder until the real answer is known, but we do know that there is something in that place and we continue to look for it. Where as the religionist only has blind faith that God exists because of a book or book written thousands of years ago, not knowing for certain whether or not a place for God even exists needing God as a placeholder.

      October 19, 2011 at 12:23 pm |
    • JasonLinMT

      Religionists use God to explain away every aspect of every idea or thing that they don't have an explanation for. Scientists only use dark matter as a temporary placeholder for things relative to a very small sliver of all existence, thoughts relative to unexplained gamma rays or the mass of the universe. For other things related to chemistry, biology, meteorology or any other branch of science not related to deep space, scientist may use other placeholders or simply admit that they don't know the answer yet, and continue to look for it. Religionists have given up any hope of understanding anything that wasn't spoon fed to them by the musings of ancient fiction writers.

      Yeah....that's not how it works. If the gamma rays came from a faraway source, its visible light would be reaching Earth at the same time as the gamma rays.

      October 19, 2011 at 11:17 am |
      • JasonLinMT

        Of course, you are assuming that whatever the source was that it emitted both visible light, and gamma radiation.

        October 19, 2011 at 11:40 am |
    • C. Smith

      That explanation doesn't work, unfortunately. Gamma radiation is a form of light, meaning that it travels at the same speed as light, meaning that the gamma radiation hitting our sensors was produced at the same time as the rest of the light hitting our sensors from the same source, and has traveled the same path. Therefore, if there is no other light from that source, then nothing producing other light was present when this gamma radiation was produced. Either that, or there's some form of filter in the way (gas cloud, for example) that's filtering out all other light and only allowing gamma radiation through. Unlikely, though, that something would filter out ALL other forms of light, but still allow gamma radiation through unfiltered.

They have built their space station in space and have unlocked new mysteries of the universe which have to do with our futures. They are not sharing this information with us.. just like plenty if other informations such as 9/11. There is a secret privately funded space program working. They are just not letting the American people know of what they are doing. They don't want us questioning them on travel to mars or life on other planets. This is an easy way to make it look as if they have quit spindle space missions. This is a front people. They will never quit on space..

'Think' would be a really big concept for them in the first place so perhaps I should find another word for what they do, or don't do...

      I wouldn't call this a waste of time, however, right now on planet Earth, there are a lot more problems that need to be resolved FIRST before we spend another few billion dollars on something that probably won't help mankind within the next generation. Think globally, act locally.

        Rachel, we've solved many of our other problems here on Earth already thanks to developments produced through or driven by space programs. The reality is that space research has and will almost certainly continue to play a major role in the improvement of life here on Earth.

        So you're saying that nothing the space program does bears fruit for at least a generation?

        So GPS, microwaves, semi-conductors, microchips, computers, numerous fire fighting advances, numerous disease cures, numerous aviation safety enhancements, numerous rescue equipment (e.g. jaws of life), numerous health enhancements (e.g. digital body scans), GoogleEarth, the list goes on... all this came more than a generation ago?

        Are you proposing that NASA scientists should try and fix the economy instead of expand our knowledge of the universe? We've had many technological advances that we take for granted because of NASA. Besides, if we go by the simplistic doctrine of "don't do anything until all the world's problems are fixed" we will never do anything or get anywhere as a society.

        Yeah, let's go ahead and put breakthroughs in the scientific understanding of our universe on hold for a while, that sounds reasonable...

        Why don't we stop research on AIDS and Cancer as well, because, you know, we've got a lot to worry about right now, like American jobs, taxes, and which republican candidate is going to get the nomination.

        Perhaps you should consider that scientists throughout the world study and interpret this information, and it just so happens that we, in the USA, have exceptional devices to capture that information. So yeah, why not... Let's just go ahead and deprive ourselves and the rest of the world from incredible breakthroughs in science. Pure genius.

    I wonder if they've already considered background scattering & gravitational lensing, from known objects?

    October 19, 2011 at 11:00 am |
    • C. Smith

      Gary, that would have the same or similar effects on all other forms of light emitted from the same source. The fact that only gamma radiation has reached us from these sources tells us that, pretty much whatever the source is and whatever course the light took to get here, it isn't producing other forms of light (or that there's some kind of very strange filter in the way which is only letting gamma radiation through).

Do you realize how much of what we do today, use today, is rooted in NASA discoveries? Shutting them down to save a few dollars is completely narrow minded. There are alot of other things we need to do without shutting down one of the key areas we excel at. Like fixing trade imbalances.

      Uh, what makes you think we can EVER solve our problems? Some will come and go, but there always WILL be problems. It's basic to the human condition itself.

      What you are really saying is you hate NASA and everything it does. Could you, perchance, be one of the science-hating bible thumpers?

      The very notion that we can ever be able to say that all our problems are solved is stupidity on the grandest of scales.

      So just SAY you hate NASA and want it shut down? We'd be able to believe that. Doesn't mean we'd think you are rational, but we'd understand how you are thinking.

      Is there some kind of revulsion you feel at being straightforward?

      But there is one problem I'd like to see solved – and soon: Religious fundamentalists who want to erase our democracy and make America a religious state – against EVERYTHING the founding fathers wanted for us.

      Only better education can quell the tide of fundamentalist leaders (politicians is what they really are) who prey on the ignorance of people.

      Nobody should EVER vote for one of those people. We already had one: Bush. His whole policy toward Israel was based on insuring that Israel would exist at the time of Armageddon, so it could take place as stated in holy writ.

      It doesn't get any stupider – or any more irrational – than that.

      Religion belongs in the heart, the home and the house of worship. NOWHERE ELSE.

I don't care what you call the force that created these laws but it exists. Some call it God. Some call it nature. You can call it whatever you want. But that force exists. Though the appearance of it all seems very random, science continues to prove how orderly everything really is.

    Won't dark matter just be space dust? As you see in an explosion not all matter will coales back into a nucleus due to gravity. A lot of the matter stays scattered. If we were to pile up all this space dust and debris I'm sure it can add up to a significant amount of matter.

    October 19, 2011 at 9:30 am |
    • Objectionist

      Yes, but space dust can be seen along the electro-magnetic spectrum. Dark matter can't. It doesn't emit "light" that we're aware of. These researchers are presenting the hypothesis that dark matter may emit "light" only at the very energetic end of the spectrum, which are gamma rays. Space dust can be seen in many many other areas of the spectrum, especially X-Ray.

    If space-time can be bent, stretched, and twisted, it is not a fundamental thing. Physicists who attempt to describe things with their field theories, in terms of space-time, will not solve the puzzle. Look instead at the most fundamental things possible: symmetry and asymmetry. Chinese philosophers got it right centuries ago - everything arises from yin and yang.

    Dark matter is always presented like it's a fact, but there's not a shred of real evidence for it. Basically, scientists noticed that other galaxies don't move the way they expected based on their visible mass. So, they invent an idea called dark matter, which no one can detect in any way, to explain the difference. It's pure speculation that's presented as scientific fact. You thought science required proof before making assertions? Not anymore, apparently.

    • ThePreacherTheTeacher

      it is a fact that to the gravitational effects that have been observed and measured very precisely (gravitational lensing, etc.) cannot be accounted for by the mass of all the observed luminous matter. Thus is it is an inescapable conclusion that an additional source of gravity which cannot be observed directly exists. That's all "dark matter" is, an explantion, and it either exists or everything that we know about gravity through general relativity and all our cosmological observations are grossly wrong, which is almost impossible given the strength of the confirming evidence. There HAS to be mass in the universe that we cannot as yet detect except for its gravitational effects.

      October 19, 2011 at 9:05 am |
      • Talgrath

        We have evidence that neutrinos can move faster than the speed of light; it's entirely possible and even likely that our calculations and understanding of gravity are flawed. For all we know, we are vastly underestimating the mass of stars for example.

        October 19, 2011 at 11:20 am |
    • Tony L. - Atlanta

      Actually, there is all kinds of evidence for it. It's statistical evidence, but evidence all the same and confirmed by independent scientists. But if it helps... the only proof that gravity exist is its behavior on other objects. We can't see it or capture it but we know its there by how other objects react to it. The same with Dark Matter.

      October 19, 2011 at 9:09 am |
    • Davethecanuck

      Had you been born a few hundred years ago... would anyone have been able to convince you that wind exists?

      Like dark matter, you wouldn't have known what wind was, how it was created or what it was made of... you could only observe it's effect and influence on objects. Still, without that understanding we knew that this force existed by infernece. We may not be able to feel dark matter like we can the wind, but we know it is there by the effect it is having on other objects.
      They are also not trying to tie dark matter to one unknown substance... this missing mass we have noticed is most likely attributed to several different so-far-unobservable or hard to see objects... brown dwarfs, ejected planets, and certainly some undiscovered particles.

    • Bill Mosby

      Science starts with an hypothesis, usually after a discovery that correlations seem to exist, or a discovery of facts that seem to refute some current hypothesis. Then it goes on to look for more evidence to refine, confirm, or throw out the hypothesis. That last sentence describes where we are on the subject of dark matter.

      A scientific theory comprises a collection of concepts, including abstractions of observable phenomena expressed as quantifiable properties, together with rules (called scientific laws) that express relationships between observations of such concepts. A scientific theory is constructed to conform to available empirical data about such observations, and is put forth as a principle or body of principles for explaining a class of phenomena.

    Man has only began to scratch the surface of peering into the universe, much less our "home", the earth. After mentioning that Jehovah God is "hanging the earth upon nothing" and that "the very pillars of the heavens shake", Job now says: "Look ! These are the fringes of his ways and what a whisper of a matter has been heard of him ! But of his mighty thunder who can show understanding ? "(Job 26:7, 11, 14)

    Even with the most capable telescopes and other instruments, the universe remains by and large a mystery. Only those who are called in the Bible, "meek"ones or teachable ones by God, will live forever and enjoy peering into the depths of the universe for all eternity.

    Psalms 37:11, 29 says that "the meek ones themselves will possess the earth, and they will indeed find their exquisite delight inn the abundance of peace....The righteous themselves will possess the earth and they will reside forever upon it."

        Just so you know, Copernicus, Kepler, Brache, etc. were all Catholic churchmen. Galileo's only real problem was that his ideas outstripped his evidence, and he tended to denigrate his fellow astronomers. And his only real contributions to science were a) that telescope and b) being the guy who got "condemned for his science" and thereby provided scientists everywhere a lovely martyr.

        @jorgath,where did you read that? In church haha. Youre missing the point, the church tried to impose its even against insurmountable evidence against their claims time and time again and as their power has waned over the centuries their reach is no longer long enough to put people on house arrest etc for merely contradicting what the church believes they should tell other people to believe. If you knew anything about Galileo you would also know that he designed an improved compass that he sold for less money than it cost to take the class on how to use it(which he taught of course) Galileo did not invent the telescope, merely a refracting lens capable of magnification. I believe hans lippershy and leonard digges were the first to invent scopes with lenses in them.

      Science & Religion don't have to be enemies. But don't start quoting the bible, especially JOB! Because while the book of Job may be considered an important literary work, as far as religion goes, IT CLEARLY STATES IN JOB THERE IS NO AFTERLIFE. not to mention it details how god and satan (the "accuser", where we got the word "satan") are friends basically. and god just goes around killing people at will! IT HAS NOTHING TO DO WITH THE SPACE PROGAM OR GAMMA RAYS.

      seriously people. this is why i get so depressed. because the world is made up of so many idiots, i doubt we'll EVER get as far as discovering the vast secrets of our SOLAR SYSTEM, much less the universe.

    I was wondering, light can be bent, refracted, slowed and sped up. Is it possible that the gamma rays come from a source we know about, but by time the light reached us it looked like it came from somewhere else?

    October 19, 2011 at 8:38 am |
    • iamthelorax

      Brad, You cannot change the speed of light. You may change the wavelength and frequency of light, which will affect its color and brightness, but the speed of light, which is a universal constant. Also gamma rays are not light, they are streams of radioactive gamma particles. Read more about Alpha, Beta, and Gamma radiation to see how they are created.

      October 19, 2011 at 9:17 am |
      • NJ

        Light can most certainly be slowed down. This is what is commonly referred to as refraction. As for the bending and twisting of the universe that has been going on for billions of years I think it is entirely possible that the sources of these particles could easily have moved so as to make a connection to them very difficult.

        October 19, 2011 at 11:00 am |
    • iamthelorax

      Correction: Light can be sped up and slowed down, but thus far only in a controlled, artificial medium such as fiber optic cables.

      October 19, 2011 at 9:20 am |
      • just saying


        the speed of light is determined by its medium. That is how optical lenses work. And that is why objects such appear "broken" when viewed while partially in water. Refraction is the changing of speed of light.

        Atheists are such hypocrites. They deride someone that takes believes in religious faith because of their blind faith in science.

        Just because we are starting to understand how God did some of the things doesn't mean there isn't a god. Remember when you were a little kid and thought your parents knew absolutely everything? Then you were a teenager and thought your parents were blithering idiots because you were starting to understand some of how the world works? Then as you became an adult, you realized maybe your parents aren't so dumb after all, because it wasn't as simple as it looked when you were a teenager. As you became older and understood things better, did your parents cease to exist? As the human race becomes older and realize how things work, it doesn't prove that there is no god. It just proves we are understanding how God did it, that's all

    Perhaps stray gamma rays from another universe or a hidden dimension, we can't know it all.

    For the religious set : Perhaps it's GOD farting out His black hole.

      That would imply that god is black. And if that's true what's all this hooey about white lights?

    Is it posible that we do not know what we do not know? If we know what we dont then that would not be an unknown because it is a known unknown? right?

    Can someone tell me how so many of you imbeciles got to this site? Better yet, how did your feeble minds even find it??? I wished that those retarded theories you all propose were real and you got struck by a Gama Ray and your privates exploded along with your heads!!! You’re all wasting precious Oxygen!!

      Imbeciles got to this site first. Moreover: the entire article, the „scientific” work about the dark matter is a piece of garbage. A return to the real science, like atomic theory is well overdue…

        Yes cause there are only 5 scientists in the entire world and everyone works on the same projects. This is a dumbed down science article for the masses so you won't get the full report. As for atomic theory, there are hundreds or even thousands of people working on it. Smaller and safer reactors don't just magically appear. Entire disciplines don't stop if no headlines are found for them.

      Aladár, you're an idiot. You just aren't smart enough to understand anything scientific.

    Could be alien life using weapons or technologies that we don't know of. I like the war idea but I hope, if it is alien tech, that it is being used for constructive forces.

    Is it possible that the galaxy is at war and we are the only dopes we don't know about it? (the gamma rays are from nukes going off)

      I think that you are right.

      All we need to do is play the Starfighter video game, score high and then be recruited to savethe universe! Simple! I think more likely that it is speacial groups of jedi-like beings radiating their version of the force Now if we just had higher counts of Midi-chlorian.... sigh. The price of the mundane human life...

        LOL, OMG, I remember that movie! It could so totally happen

      Or, maybe this is the reason we haven't discovered intelligent life... every intelligent scientific species reaches a point where they conduct an experiment that destroys their entire world. The only thing left to indicate their civilization even existed is the burst of gamma rays spreading out across the universe from their destruction.

      Or, something more boring and less tragic perhaps...
