The Palomar Observatory adaptive optics image of the crater Cabeus remains the best I've seen from ground-based telescopes of the LCROSS impact site.
Here's the sharpest optical image shown today of the Moon, from Palomar Observatory.
I am pretty sure this image shows the LCROSS impact plume and its shadow as seen from the MMT observatory in Arizona, but as Alan Boyle just pointed out, the time stamps indicate the photos were all taken before the nominal impact time.
Timothy Reed explains how optical telescopes are tested for gravity sag, and the methods used to counteract or compensate for it.

Farewell to Hubble, Obama Calls, Astronauts Testify to Congress as Shuttle is Set to Land
On Monday, if all goes well, we will launch the Space Shuttle to rejuvenate one the greatest scientific missions launched on or off the Earth: the Hubble Space Telescope.
Planetary cartographer Phil Stooke has been working on a cool project to compose and compare maps of Mars that show how we saw the planet throughout the Space Age.

After the political discussions of the morning, Mike Brown stood up to give the
I got an email last night from Anne Verbiscer, whom I had contacted about rounding up some amateur astronomers to help the Cassini mission with some photometric observations of Hyperion.
At a press briefing, the co-discoverers of the so-called
There were a few talks at the Division of Planetary Sciences meeting dealing with a rare and fortuitous event that happened on January 13, 2005.
Uranus has the unfortunate reputation of being the most boring planet in the solar system. But where it appeared to be a nearly featureless, hazy blue ball to Voyager 2, it is now blooming dozens of clouds that are visible to the sharp-eyed Keck II Telescope.
This morning, asteroid 4179 Toutatis was so close to Earth that simultaneous observations from two telescopes in the same country could show parallax that is obvious even to the least experienced observer. The two telescopes belong to The European Southern Observatory and are located at La Silla and Paranal in Chile
