Reports: Astronomers capture impact on Jupiter's surface

A fireball thought to be an asteroid or comet hitting the surface of Jupiter was captured by two amateur astronomers early Monday, reports.

One of the astronomers, identified as George Hall from Dallas,  posted a screen shot in multiple reports  and wrote about the discovery on his blog, George’s Astrophotography.

“The impact was observed by Dan Peterson visually this morning,” Hall wrote, crediting another space enthusiast with making the initial observation and posting what he saw online.

“When I saw the post, I went back and examined the videos that I had collected this morning …” he wrote in a post describing how he captured a video of the impact. “The video was captured with a 12" LX200GPS, 3x Televue Barlow, and Point Grey Flea 3 camera. The capture software was Astro IIDC.”

Hall posted a four-second video of the impact. He wrote that it was taken at about 6:35 a.m.  Monday on his Flickr page. compares Hall’s images with other impacts to Jupiter’s surface reported by NASA in 2009 and 2010.

A NASA Science News post from September 2010 stated: “Jupiter is getting hit surprisingly often by small asteroids, lighting up the giant planet's atmosphere with frequent fireballs.”

The post went on to say that Jupiter is frequently hit by small objects, causing impacts “bright enough to see through backyard telescopes on Earth.” wrote: “Astronomers around the world will now begin monitoring the impact site for signs of debris - either the cindery remains of the impactor or material dredged up from beneath Jupiter's cloud tops.”

    This is so interesting. Once a month or so the local astronomers get together with the public and look into the heavens. Im older but starting to get the bug!

    Asteroid impacts on Jupiter are cool but what I want to know is how come Jupiter got nearly all the angular momentum of the Solar System and the Sun didn't get squat. That heavy gas ball rotates every 10 hours or so. Could Jupiter really be a failed star? Why can't you astronomers figure that out? Inquiring minds want to know.

    As soon as we heard the news, we pointed the telescopes at Jupiter for the following 48hrs. I've just finished a Jupiter time-lapse from last night ( – absolutely no sign of any impact soot from Monday's comet or asteroid hit.

    One of those babies impact earth and it's Goodnight Irene. One million years of human existence on planet earth – gone for good in a few minutes, without so much as a trace. We are puny, and hanging on by a thread.

    Nah. Just because Bush sat there reading "My Pet Goat" while we were under an attack that could have been prevented had he and his big Dick not ignored the warnings of the intelligence community doesn't mean Dim Son is responsible for events on Jupiter. Though I'm sure Bush has a great influence on Uranus, eh Sarge?

    If you play the video very slowly you can see "them" as they ride the light through the atmosphere on their way to their machine deep inside.

    There are those who believe that life here began out there, far across the Universe. With tribes of humans who may have been the forefathers of the Egyptians, or the Toltecs, or the Mayans. That they may have been the architects of the Great Pyramids, or the lost civilizations of Lemuria or Atlantis.
    Some believe that there may yet be brothers of man, who even now fight to survive–somewhere beyond the heavens

    I don't believe this was an impact ... remember shoemaker-Levy 9? It left black clouds on the planet after impact ... this left no remnants as someone else suggested earlier. We should have seen something just after if it was an impact. I hope the video keeps rolling as I suspect we will see more soon.

      If not an impact then perhaps it was a launch. No geo activity on Jupiter.

      Wow you really are clueless. We don't give NASA funding to sit and stare at Jupiter every night NASA is charged with other pressing missions of far greater importance and besides the universe is a pretty big place no one can watch everywhere all the time.

        Actually Schmed, I'd have to question the IQ of those who agree with funding NASA only for them to hoard all the REAL data while feeding us little tidbits of crap in order to keep the funding coming. We're suckers for not demanding that all NASA top officials kindly step away from their desks and leave permanently with only personal effects (coffee mug, etc.). We own everything in the building.

      I agree Huh? In fact, NASA has accomplished little more than regurgitating WWII Nasa bottle rocket technology while CONSUMING massive amounts of funding. The idea they can't "watch nine planets" using a couple of old computers is NASA-speak. "We're just too darn important to watch what's blowing up in our local universe." lol PULL NASA'S FUNDING.

    On the website of the astronomer who recently discovered an interesting cloud formation on Mars and he reports that the fireball didn't cause an impact with any remnants. He shows pictures of Jupiter from yesterday morning (very good ones.)

    How can a ball of gas have a "surface?" Isn't Jupiter a gaseous planet? What exactly is getting hit by these asteroids and comets that hit Jupiter? I'm not trying to be flip, just seeking an explanation.

    September 12, 2012 at 3:24 pm |
    • Steve

      It is the atmosphere that is being hit. Similare to when a meteor hite earth. It is the burning as it travels through the atmosphere that is visible. The actual hit on the ground is not visible. I'm not sure if the gas on jupiter is ever dense enough to be classified as ground like we have here on Earth.

      September 12, 2012 at 3:28 pm |
    • thedoctor


      You are correct that Jupiter has no "surface," rather an every increasing density and pressure until it turns to liquid. The object doesn't necessarily "impact" but it does begin to burn up VERY quickly and if it shatters, all of it's energy is released at once, like an explosion. For extra credit, look up the Tunguska event.

      September 12, 2012 at 3:52 pm |
    • ct

      There is some kind of core or surface on Jupiter or it cant have magnetism.

      September 12, 2012 at 4:39 pm |
    • John Hix

      No surface but a strong gravity and atmosphere to burn up an asteroid.

      September 12, 2012 at 4:58 pm |

        It does have a rock/metal core.And metallic hydrogen.

    It would have been so cool to be viewing Jupiter when the impact took place. Jupiter is fascinating enough even when it's not being hit by something. Way to go, backyard astronomers!

    I thought Jupiter didnt have a solid surface?

    September 12, 2012 at 2:48 pm |
    • Seraphim0

      It doesn't, but entry into an atmosphere causes heat due to friction. Since Jupiter is a gas giant, some of the contents of its atmosphere can catch fire briefly, hence a fireball effect upon 'impact.'

      September 12, 2012 at 2:52 pm |
    • Deane

      True, the article is technically misleading about Jupiter's "surface" being hit. It would be better to say it hit the atmosphere.

      September 12, 2012 at 2:56 pm |
    • hecep

      It does have a solid surface at its center, which basically, last I read, amounted to a giant diamond.

      September 12, 2012 at 3:05 pm |
      • Curtis

        I don't think it is believed to be a diamond (compressed carbon), but rather metallic hydrogen. It is the likely source of its immense magnetic field.

        September 12, 2012 at 3:15 pm |
      • MDAT

        No.It is a rock and metal core.

        September 12, 2012 at 3:53 pm |
      • JoeyE

        iron/nickel is a must for a core to run an electromagnetic field.. hydrogen does not. Our Sun had plenty of iron in it's core. therefore it works for magnetic as well as gravity

        September 12, 2012 at 4:06 pm |
      • MDAT

        Metallic hydrogen does work with a magnetic field.It makes up much of Jupiter.

        September 12, 2012 at 4:09 pm |
    • Jose

      Basic science should tell you that Jupiter has a solid core. Denser materials always sink. So imagine all the rocky meteors etc that have crashed into Jupiter. All the denser materials will all eventually sink to the center. So yeah it has a solid core, probably larger than Earth.
