Carnival of Space #28 is now up, hosted this week by Emily Lakdawalla at the Planetary Society Weblog. Comet Holmes and the planets of 55 Cancri are the hot topics from multiple bloggers (including me), but there are plenty of other fascinating posts to explore on a variety of space and astronomy topics.
Emily does a nice job on this carnival, as she does in all of her writing, which in keeping with the goals of the Planetary Society, delves deeply into planetary science and exploration, mostly in our solar system, but sometimes in others. The Planetary Society was founded in 1980 by Carl Sagan, Bruce Murray, and Louis Friedman to encourage the exploration of our solar system and the search for extraterrestrial life. Its activities are well worth supporting and I am proud to be a member.
