Comet death may hint at birth of Earth

It may be the closest thing to hell ever observed by science.

Researchers revealed breathtaking images on Thursday of a kamikaze comet called C/2011 N3 (SOHO) taking a swan-dive into the sun.

Images and research published in the journal Science show a house-sized rock plummeting at more than 1 million miles per hour through million-degree temperatures to within a relative hair's breadth of the sun's surface.

Observations like this have never been seen before, says Karel Schrijver, who led the research at Lockheed Martin Solar and Astrophysics Laboratory in Palo Alto, California. "It's never been observed anywhere near this close to the sun."

Comets that brush by the sun are called sungrazers. Thanks to orbiting satellites that can better observe sungrazers, scientists believe they can learn more about how the sun works and the ancient beginnings of Earth.

Analysis of data from last July's comet strike paints a picture of a fascinating ride into a virtual hell.

Imagine sitting on top of the comet as it streaks toward the sun at more than 1 million mph. Looking like "the dirtiest snowball that's ever been made," the black, half-rock, half-ice comet pours off vapor and dust due to evaporating water streaming from its surface at 1,000 mph, says Johns Hopkins Applied Physics Laboratory planetary astronomer Carey Lisse, who reviewed the research.

Closing in fast, the comet hits the sun's 1,000,000-degree Fahrenheit corona, creating a fiery shockwave of gas in front of it. The ride gets bumpier and bumpier. The comet begins to rotate faster and faster, and it begins to shed chunks.

Finally - about 62,000 miles from the surface of the sun - nothing.

A 70,000-ton rock's 30-minute suicide dive into a raging cauldron reduces it to vapor.

"That's when we realized we'd not just captured a comet, we'd actually seen it vanish - the end of the life of that particular comet," says Schrijver. "It had completely evaporated."

By studying how comets fall apart, scientists may be able to reverse the process and learn how planets are formed, says Lisse. We still don't know how space dust - a.k.a. "the stuff between the stars" - coalesces to form planets. But comets are made of this stuff. So if we can figure out how comets are created, we'll know a lot more about how Earth formed.

"Comets really are the dinosaur bones of solar system formation," says Lisse. Hundreds of comets brush by the sun each year, experts say, but only one or two per year actually hit the blazing bullseye.

July's sungrazer was a piece of the Kreutz comet, Lisse says, a larger object that broke apart thousands of years ago yielding spectacular comets reported on Earth in the years 1106, 1843, 1882 and 1965. The last of those, called Ikeya-Seki, was bright enough to be seen during the day.

Lockheed Martin's paper stemmed from combined data from NASA's orbiting Solar Dynamics Observatory (SDO), Solar Heliospheric Observatory (SHO) and the Solar-Terrestrial Relations Observatory (STEREO).

As more sun-grazers are pinpointed, scientists may be able to learn clues to a comet's makeup by performing thermal desorption spectroscopy, Lisse predicts. It's a technique that identifies the comet's elements by the type of light it gives off while the sun toasts it like an interstellar marshmallow.

Lockheed Martin's scientists determined C/2011 N3 (SOHO)'s mass by measuring energy from the sun's light and the amount of energy it takes to evaporate material off the comet, says Schrijver.

By observing more sungrazers, Schijver hopes to uncover mysteries about the region around the sun that's been hidden by extreme light conditions. He's interested in learning more about the acceleration of charged particles given off by the sun - the solar wind.

"These are places that we have no other means of exploring," he says.

So, get ready to see more hellish images of building-sized boulders vanishing into thin air on the surface of the sun. "I predict this is just the beginning," says Lisse.

Just last month a comet dubbed Lovejoy crashed into the sun and actually survived - astonishing many amateur and professional astronomers by piercing the sun's super-heated atmosphere without being pulled in and disintegrated.

Schrijver says teams are already being assembled to track other sun-grazers with the SDO satellite.

In effect, by their demise, comets become nature's scientific probes, possibly to unlock a treasure trove of  knowledge about our solar system.

    I'm just writing to let you be aware of what a cool discovery my cousin's daughter enjoyed browsing your web page. She mastered a lot of issues, which include how it is like to have an excellent coaching style to get many others completely thoroughly grasp a variety of tricky subject areas. You really did more than visitors' desires. Many thanks for rendering the necessary, trusted, explanatory not to mention fun tips on the topic to Tanya.

    Regarding Bible revisions, as spoken about above, there have been more than 2,000 and what we have today for reference, is the King James version. Moses originally had five, expanded to 45 or so, and many of those revisions have been "revised out". I'm sure another revision of the Bible is in process somewhere. As the universe and man were made in violent events, there will always be conflicts present in our existance. Only if we could learn to accept the diffierences between ourselves, how far could we truly go? for what its worth, I believe in on more than me (God) and science. Its impossible to seperate God from science, if you choose to believe, as he is the greatest of all scientest. As for those scientific greats and those not so great that he has blessed us with, let them keep coming, experimenting, and unravleing the mysteries of our existance in peace.

        Prove that he doesn't tiny timmy weewee! It takes a "brilliant" mind such as the one you posses to even assume that your point relates to the issue raised in mine. If, without research, you can explain what a unit of plank time is, I'll entertain discussing more with you, if not........

        well actually YOU have to prove your god exists as you are making the hypothesis that he does. it would be the same if i said invisible elephants exist, then i would have to provide proof. so it's all on you buddy

        January 25, 2012 at 4:22 pm |
    • IBlake

      Your assumtion is wrong. i don't have to prove anything, for in the example you give about an elephant of some type, as long as you believe it–that's good enough for me. the most important feature about you is your mind (and its ability to not only think but to also create). With such a powerful tool at my disposal, i could create God, place same in your hands, and you would still question the matter. In the religious argument you seek to build, i have no interest, as with many things including many based scientific observation are not proof in themselves, but only the best arguable theory availiable at the time, most of which are still waiting to be truly confirmed.

      You do know that the part of the brain that determines love is located right next to the part that determines hatred so often times the lines are blurred...you may need to reflect on your true feelings for Sarah because its very clear to all cnn posters that you have an infatuation with her even if its "negative" like you try and portray. You act somewhat like a 2nd grader putting gum in a girls hair and calling them names to distract from the fact that your in denial and secretly in love them...i know, i know the truth hurts but everyone needs to face their demons...even trolls.

        Interesting theory but I disagree in as much as I pretty much bash anything to do with baggers, birthers, evangelicals, christian conservatives, republicans, rednecks, and other assorted vermin who seem to be committed to launching our country forward to the 12th century.

    I learned in an intro to astronomy class that planets were formed by accretion – matter slowly spinning around the sun, faster and faster until they became so dense they were a planet....

    January 20, 2012 at 10:52 am |
    • ChaoticDreams

      it's worded very poorly, but i think what they're trying to understand is not how the planets themselves formed (which was accretion), but rather how their particular orbit became stable and in their current locations

    Actually, it more than "merely" evaporated. When something evaporates, it turns into vapor, but the component atoms still exist. When this comet crashed into the sun, not only do the molecules get pulled apart, but the atoms are stripped of their electrons (plasma-ized) and they undergo nuclear fusion, which fuels the sun.

    January 20, 2012 at 10:50 am |
    • Nonimus

      Interesting, you may be correct about the plasma, I'm not sure, but I doubt that they are undergoing fusion in the corona of the sun.

    Caption on the picture says 400 mile per SECOND
    Detail in article says comet was going 1million miles per hour
    400m/s * 60s/hour = 24,000 mph 1million m/h

    Did someone at CNN slip a decimal or translate the article from metric? Either way, seems to be a bit off with the math and hyperbole.

      January 19, 2012 at 6:09 pm |
    • Primewonk

      400 miles/hr * 60 seconds/minute * 60 minutes/hr = 1.4 million miles/hr

      January 20, 2012 at 9:57 am |
    • AL in West Palm Beach

      Ok, here is the complete answer.

      1. Comet travels at 400 m/s
      2. They are 60s in 1 minute, and they are 60mins in 1 hour

      Now, let's find how many seconds are in 1 hour. So it's 60 * 60 = 3600 seconds
      Therefore if the comet was traveling at 400 m/s to find out how fast it was going per hour you would multiply it's speed/perscond times 3600s because that's 1 hour. So 400 * 3600 = 1,440,000.

      Thefore, the comet was traveling at a speed of 1, 440, 000 mph.

      January 20, 2012 at 10:28 am |
      • AmazedinFL

        conoclast, it might 'nag' just because it's really hard to fathom something moving at over 1 million miles per hour, based on speeds at which things move in this world (i.e., our everyday experience).

      • johnP

        But you know John – we often feel like you are shoving sience down our throats. I listen to what the sientists tell us with interest, but it is always changing! The Bible does not change. So we express our beliefs and people like you call us horrible names. Why can't you allow us to have our beliefs with dignity? You know I think it is because you question deep down inside what you believe. God created sience, but it is man that can interpret it all wrong. And some times we interpret the bible wrong. Lets exchange ideas and beliefs and allow each others dignity to stay in tact.

        January 19, 2012 at 5:49 pm |
      • Mo

        I hate to break it to you but the bible has changed. Several times. Christian history even admits it. Do some research and you'll see. While you're at it look at whos changing it and when. I believe in God but not Christian.

        January 20, 2012 at 10:47 am |

        Actually, the story speculates about origins, built on a philosophical bias of naturalism and materialism. Not quite sure where you got the myths part.

        When i was young i had blind faith in science. I was addicted to the knowledge i gained. One day when science changed their mind about how long it takes to fossilize a bone, and were off by a few million years, i gave up because i realized i really had "faith" and in that, they let me down. Still love science but realize 80 percent of it is still devloping and not true. I wish they would state that as well

        JB, I'm assuming you're still naive enough to think every story in the bible is original. Literally every story in the new testament was previously written by another culture hundreds if not thousands of years before. For example, change Dionysus to Jesus and Zeus to God. Poof!

      In fact, your version of a god was so scientifically ignorant, that he completely screwed up his order of creation. This universe began expanding 13.7 billion years ago. But the earth was't formed until 9 billion years later. But your god thinks he made the earth before he made any stars. He also thinks me made vegetation on earth before he made the sun.

As a result, the YOY graph shows a delayed reaction of the market by up to a year. in your analogy, if you had cancer and were getting worse month by month for years, but you have finished chemo and are now getting better day by day, you are in the recovery stage, even if you aren't as good as you were a year ago, you are still better than you were yesterday, or a month ago, so you are rvoreecing. It may take a year before you can say you are better than you were a year ago. When the YOY change graph shows 0% change, we will be well past the bottom and into recovery. Whether we are in recovery now is still up for debate though. Personally, I would agree with Trigger, a slower rate of decline is an improvement and a sign of recovery.

      It was in the ground somewhere below your feet. That is until science gained the ability to probe the Earth's surface for resources, and seismologists were able to map the inner Earth over time by analyzing global seismic signatures. It was then, that Satan(tm) himself decided he better pick up and move. Because he fears ending up in Guantanamo Bay accused of terrorism for 'making people do bad things', and other annoying things... such as the highly feared 'gnashing of teeth' as mentioned in the bible.

        Sort of like when Galileo discovered the imperfections on the moon and thus the heavens causing christians to say, "well even though we've been saying god and heaven are above us for the last 1500 years, they're not REALLY above us... come on... it's only literal if we really really mean it... or until we know more... wait, what? the earth is round? crap."

    I'm sure this has been considered...but IF we could inexpensively send nuclear waste into space, then give it a gentle push towards the sun, it would seem to be a good way to get rid of that dangerous material (better than burying it somewhere, no?) It won't matter how long it took, eventually it would arrive at the Sun and be consumed.

    I'm not a proponent of nuclear energy because we have no truly safe place to put radioactive waste. Sending it into the Sun would seem a possible alternative (though I'm certainly no expert.)

    January 19, 2012 at 3:27 pm |
    • SeanNJ

      The problem is a single failed launch that deposited all that material in the atmosphere would be no less than catastrophic.

      Nuclear waste is extreemly dense and heavy. Aside from the safety concerns it would not be cost efficient.

    • knghtshingrmour

      The reason is you can not use a gentle push. Think of an ice dancer spinning, as they bring in thier arms they speed up and slow down when the extend thier arms.
      The Earth travels around the sun at about 67,000 miles an hour (google it if you do not believe it). To get into orbit, like the space station you need about 17,000 miles an hour. So it takes 4 times as much speed to cancel Earth's orbit and get to the Sun as it does to get to the Space Station.

      Now you can slingshot past the Earth or other planets to redirect your course and make it there with less rocket but it takes someone costrolling it along the way as we would hate to have it return home. If you look up The Messenger Mission to Mercury you'll find out how hard they worked to just get it in as close as the PLanet Mercury.

      Best leave these things to people who unserstand basic Physics.

    "July's sungrazer was a piece of the Kreutz comet, Lisse says, a larger object that broke apart thousands of years ago"

    How about "is thought to have broken apart" or "may have broken apart". Was there a witness when this (allegedly) happened? Please don't present information as fact which can never be proven. Please identify theory/estimates/conjecture as such.

      When you were out of your house yesterday at noon, how do you know that your clocks ever actually read noon? How do you know that they didn't just jump from 11:00 to 01:00? Do you have witnesses that they read 12:00?

      January 19, 2012 at 4:14 pm |
      • Edumucated

        Having been able to observe time and again how clocks work, empirically proving that the essential functions of clocks are predictable, one can assume that a working clock, unless it stops, will operate as designed... by the person who designed and built the clock. Consider my mind unblown.

      They do this by tracing the orbits backwards.

      You know, your brand of ignorance is perhaps the most virulent of all. Complete misunderstanding of the scientific method, coupled with no inhibitions about sharing your uninformed opinion.

      January 19, 2012 at 4:15 pm |
    • Dan, TX

      I agree with Chris, it is a probability, not a fact. Perhaps be retracing the trajectories into the past the trajectories overlap near each other, making it a logical speculation that they originated from the break up of a larger object.

      January 19, 2012 at 4:35 pm |
    • Achernar

      Actually, many fragments of Kreutz have been observed. They just list the large ones. I agree that 1106 is just a possible fragment. The recorded observations are not good enough to be completely positive. For 1843 and 1882, astrometry was more than precise enough to determine the exact orbit. Given that orbits occur in three dimensions. The possibility that several recently (pretty much anything since the telescope was invented) observed objects could share the exact same orbit and not be from the same parent object is extremely remote. This is far more than just “overlapping trajectories”. Also, for any of the fragments observed in about the last century, they have used spectroscopy to demonstrate that their compositions are also identical.

    I don't think that comet "hurdled" into the sun as it did not eventually overcome an obstacle. It more likeley hurtled toward the sun.

      Science is great.. But it is just discovering what has already existed , what exists..
      When science creates anything huge. Like nuclear power.. It creates great harm...
      Science can be our undoing too.. When man is doing the creating.. Because man is in and of himself. just a creation of some thing greater.

        Just because science creates something huge doesn't necessarily mean it harmful. The sun is nuclear power and it is the engine that has made it possible for life to exist here on Earth.

        Yes the universe is far greater and we are a creation of it. Science can do allot of harm caused by man but not near the harm caused by people who believe in some mythical God that doesn't exist. Science in the right hands can tell us where we actually came from.
