Stories, updates, insights, and original analysis from The Planetary Society.
Last Tuesday at the Division of Planetary Sciences meeting Bruno Sicardy presented the results of his research group's observations of a stellar occultation by Eris.
It's been a very full day at the DPS-EPSC 2011 joint meeting. My day was less full than it might have been, because I overslept and missed most of the morning's session. I really needed the rest though so I think it was probably for the best!
Today and tomorrow I'm attending the New Horizons Workshop on Icy Surface Processes. The first day was all about the composition of the surface and atmosphere of Pluto, Charon, Triton, and other distant places.
NASA funds regular meetings of scientists who work on different parts of the solar system to provide scientific input into NASA's future plans. These
While doing my daily reading today I was struck by the awesomeness of two recent blog posts. Both were composed not by professional bloggers like me but by professional space explorers, one a scientist and the other an engineer.
A guest blogger here recently rounded up the large number of participatory research projects that are collectively known as citizen science. I think these are all very cool and I encourage you to check them out but none of them has yet inspired me to spend my precious time as grunt labor on a gigantic collective project. Until now.
On May 5 and 6, I had a run on the WIYN (Wisconsin-Indiana-Yale-NOAO) telescope, a 3.5 m telescope, the second largest telescope on Kitt Peak in Arizona.
The last decade has seen an explosion in our understanding of the solar system with the discovery of the largest Kuiper belt objects (KBOs) of comparable size to Pluto.
Earlier this week I got all excited about the Orcus-Vanth system. It turns out there was a math error in the version of the paper that I read, which resulted in the notion that Vanth could be nearly as big as Orcus.
Several astronomers pointed their telescope at Eris to watch it pass in front of a background star. Occultations permit precise measurement of the diameters of distant, faint objects, and it turned out that Eris was much smaller than previously thought, so much so that its diameter may turn out to be the same as, or even smaller than, Pluto's.
A contest has just been announced that appears to create a pathway for schoolchildren to suggest names to the International Astronomical Union for minor planets -- all those small things in the solar system that don't orbit the eight big ones.
I just posted my writeup of today's press briefing on a new map of Pluto produced from Hubble images. The main conclusion was that Pluto has shown an astonishing amount of changes across its surface between 1994 and 2002 -- more, in fact, than any other solid surface in the solar system.
The second report by Ted Stryk from the New Horizons science team meeting, focusing on the search for Kuiper belt object (KBO) targets.
The New Horizons science team is meeting this week. Ted Stryk was invited to attend the meeting, and he sent the following notes from the first day.
There are two cool stories circulating today on the theme of discovering new places in the cosmos.
I spent a large portion of the day at the Lunar and Planetary Institute's library and presented my own poster during the poster sessions, so my coverage of Thursday's sessions is limited.
After the political discussions of the morning, Mike Brown stood up to give the
Since the discovery of 2003 UB313, larger than Pluto, there's been a lively debate going on in many places about what makes a planet. There's now an article in Nature talking about a proposal that would address the controversy
At a press briefing, the co-discoverers of the so-called
