New black spot on Jupiter (asteroid impact?)
Bad Astronomy ^ | 7/19/09

Posted on 07/20/2009 12:16:36 AM PDT by LibWhacker

Jupiter’s new black spot The black spot is at the top of this image.

I just saw on Twitter (hard to believe I ever thought Twitter was useless) that Jupiter is sporting a new black spot near its south pole. You can see it in the picture here (click to go to the source and embiggen).

People on Twitter (and on that site linked above) are speculating that this is the result of a large impact on Jupiter, similar to what happened in 1994 when comet Shoemaker-Levy 9 slammed into the big planet. But I think that’s premature; weather changes rapidly on Jupiter, and black spots have appeared before — see here and here. That doesn’t mean this isn’t an impact event (or, for that matter, the earlier events weren’t either) but it’s jumping the gun to call it an impact event before we get more observations. I will add that this new spot is indeed very dark, which means it’s pretty interesting no matter what it is!

A black mark about half the size of the Earth? Ouch.

If I was watching that up close and personal, there’d be a new brown spot on my shorts.

Please visit my Facebook page. I have posted information for how you can send money by PayPal to help the people of Jupiter after this meteor impact.

Well, the photograph was taken in Australia, mate.

Please correct me if I’m wrong; but isn’t the entire surface we see nothing more than gasses above the surface. If that is the case, than the spot is nothing more than a clearing in the clouds

No, you're right about that. There's no solid surface on Jupiter, only cloud tops (which is what they mean when they talk about the "surface of Jupiter").

When Shoemaker-Levy hit the planet, the impact sites were dark because of dark material the comet itself delivered to Jupiter and because of darker material the impact churned up deeper down in the atmosphere. Comet fragments would penetrate some distance into the atmosphere, explode, then plumes of this dark debris shot out a couple of thousand miles before collapsing back onto the surface. I'm guessing it's the same here, if this is an impact.

All these worlds are yours except Europa. Do not attempt landings there. Use them together. Use them in peace.

Maine is “Down East” because older New England navigational charts were “west up”.

The Jupiter strike could be an asteroid or maybe a comet chunk similar to Shoemaker-Levy 15 years ago.

If the time period were 12 years it would seem more likely another piece of that comet.

Just as our earthly “meteor showers’ occur at the same date annually, Jupiter’s would occur at each Jupiter year (Jupiter year = appx 12 Earth yrs)

(PS - like your screen name)

That was early cgi effects- - the cost and time were so high that in the last scenes of the digital animation of Jupiter, it went to black and white.
In the movie they explained that the planet ‘lost its’ chemical stench’.

That could have really made a mess of things if it had hit earth.
