The Phoebe ring
Sorry I'm late to this news, but as usual I'll try to compensate by being thorough! Last week, planetary astronomers Anne Verbiscer, Michael Skrutskie, and Doug Hamilton published a paper in Nature succinctly titled "Saturn's Largest Ring." In the... More»

That psychedelic M-cubed Moon movie explained
Advance warning: this entry may be a little technical for some. I hope that the following makes some sense! When I posted my writeup of the Chandrayaan-1 Moon Mineralogy Mapper (M3) results detailing the discovery of widespread water/hydroxyl in... More»

AMASE 2009: Testing future Mars surface instruments in the Arctic
I have just posted four more blog entries from Juan Diego Rodgriguez-Blanco detailing the work conducted during this year's Artic Mars Analogue Svalbard Expedition (AMASE), mostly concerning the testing of instruments that are being developed for... More»

OMG! Aurora!
This is SO cool. Unmannedspaceflight.com member Astro0 was fiddling around with an interesting-looking sequence of Cassini images when he discovered their purpose -- they were gathered in order to see if Cassini could catch aurorae flaring into... More»

Video from Palomar Observatory on LCROSS impact night
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. They've now released a time-lapse video of 12 minutes' worth of observations, embedded below. ... More»

Lunar Reconnaissance Orbiter Diviner detection of LCROSS impact
The Lunar Reconnaissance Orbiter Diviner team just released some preliminary views of their data taken during the LCROSS impact, which clearly shows the thermal signature from the crash into the Moon. I'm too tired for analysis so will lazily... More»

Graphics from the LCROSS press briefing
EDIT OCT 10 2:48 PM: I just realized that the images of the impact flash from the mid-infrared camera were all released mirror-reversed, so I have corrected their orientation below. It's not incorrect for something to be rotated 180 degrees, but... More»

LCROSS: A "morning after" wrapup
So the big drama on LCROSS is over. There's every indication that the mission was successful: the Centaur spacecraft crashed where it was directed to, and the LCROSS shepherd spacecraft captured what appears to be a beautiful mutlivarite data set... More»

LCROSS visible spectrometer data showing impact flash
This plot just shows the aggregate radiance in ultraviolet and visible wavelengths -- all wavelengths -- seen by one of LCROSS' spectrometers after the Centaur hit the Moon. Not much can be read from this graph except for the very, very good news... More»

Palomar image of crater Cabeus after LCROSS impact
Here's the sharpest optical image shown today of the Moon, from Palomar Observatory. You can see a notch in the bright mountain ridge in front of the crater, and a sunny spot on the far wall, which together appeared to look like a plume and its... More»
