PASADENA, California A large comet or asteroid has slammed into Jupiter, creating an impact site the size of Earth, pictures by an Australian amateur astronomer show.
NASA's Jet Propulsion Laboratory confirmed the discovery using its large infrared telescope at the summit of Mauna Kea in Hawaii, said computer programer Anthony Wesley, 44, who discovered the impact zone while stargazing at home.
News of Wesley's find on a backyard 14.5-inch reflecting telescope has stunned the astronomy world, with scientists saying the impact will last only days more.
Wesley said it took him 30 minutes to realize a dark spot rotating in Jupiter's clouds on July 19 was actually the first impact seen by astronomers since a comet collided with the giant planet in July 1994.

That’s pretty much the conclusion one is left with!
Though the sum of the masses of Pluto and Charon is known pretty well (it can be determined from careful measurements of the period and radius of Charon's orbit and basic physics) the individual masses of Pluto and Charon are difficult to determine because that requires determining their mutual motions around the center of mass of the system which requires much finer measurements -- they're so small and far away that even HST has difficulty. The ratio of their masses is probably somewhere between 0.084 and 0.157; more observations are underway but we won't get really accurate data until a spacecraft is sent.
That story is a little too convenient. I suspect he had something to do with it.
I’ll never forget being up high in the mountains and seeing Comet Hyakutake’s tail across half of the sky.
Took me a bit to get what you meant, then.. LIS. Laughing InSide, where it counts.
Whose turn is it to empty it out?
I'd always heard that the earth collision that produced the moon is believed to have liquified the earth and the colliding body, allowing both the moon and the earth to coalesce into the round bodies we see today.
How could a liquifying event leave a crater?

You mean the one that flew into Uranus? :)
No, Obama's. He has so many, he hasn't noticed one more though. He bowed to the Saudi king for a reason...
****How could a liquifying event leave a crater?****
Homer: That’s not a crater, that’s Earth’s belly button.
LOL, “You say Uranus I say Urectum, let’s call the hole thing off”

and on and on. Quite the group.
It would appear that Jupiter lacks such groups....

Good point. Pluto is such an odd case that it may not even be a “planet” in any sense of the word.

It has been suggested that God put the planets around us the way he did to act as a “space crap” filter, basically pulling stuff in and taking the hit to keep things relatively clean for us.
So far, during recorded history, it’s pretty effective.
There are some times when I wish I lived in the Southern Hemisphere. The spectacular display of Comet McNaught in 2007 would have been amazing to see:

Oh sure. Blame the software first.

Awesome picture.
