On the first half-nights of November 29 and 30 UT, telescope time with the W.M. Keck II telescope and its Adaptive Optics (AO) was granted to us. The goal of this observation program was to search and study multiple asteroids. Since Jupiter was close to its opposition and observable at the beginning of the night, we spent a short amount of time to observe Io, innermost Galilean satellite of Jupiter, well-known for its exotic and spectacular volcanism. An adaptive otics system (AO in short) removes in real time the effect of the atmospheric turbulences which blur the images collected from the... read more ❯

Today I decided to write a short post on observations that we did using the Keck telescope and its AO system about Io. Like last year, my summer is busy with the REU students of the SETI Institute. I will write a specific post on two students who are working with me and their project in a few days. I obtained telescope time at the end of June 2010 with the W.M. Keck II telescope... read more ❯
