Peter Edmonds is the Chandra Press Scientist and, in addition to his work on publicizing Chandra science, has been heavily involved with the Chandra's Senior Review proposal since 2008.

In science, "peer review" is used to describe a process that determines whether a research paper should be published in a journal. One or more experts review the paper and determine its fate: are the results and discussion reliable and do they meet the publication standards of the journal?

We are very proud to announce that the Chandra X-ray Center's Dr. Christine Jones is the recipient of the 2013 Secretary's Distinguished Research Lecture Award from the Smithsonian Institution.

The award recognizes a scholar's sustained achievement in research, long-standing investment in the Smithsonian, outstanding contribution to a field, and ability to communicate research to a non-specialist audience.

Christine has been part of the Chandra family since before "Chandra" even existed. She started her work in the field of X-ray astronomy as an undergraduate at Harvard. With the 1970 launch of Uhuru, the first satellite devoted exclusively to X-ray astronomy, Christine studied Cygnus X-1, a binary X-ray source in which a black hole orbits a normal star.

One of our favorite games to play with our kids is trying to find recognizable objects in clouds as they pass by on a sunny day. One cloud might look like an elephant, the next, a pirate ship.

Welcome to this week's Carnival of Space. It's been a busy Universe out there so let's jump right into it.

The Urban Astronomer has an excellent recap of Hubble's observations of a very unusual asteroid. This asteroid not only has a comet-like tail, it has six of them. Oh yeah, and they apparently change.

Over at the Smithsonian's Air & Space blog, they discuss a very provocative issue: if we go back to the Moon, where should we go and, maybe more importantly, where shouldn't we?

In advance of the recent Maven launch to Mars, the good folks over at Universe Today feature an excellent video that summarizes where the Curiosity rover has been and also where it will be heading in the future.

The biggest science news this week, by far, has been a new study suggesting that Earth-sized planets in habitable zones may be very common. This is exciting news – who wouldn't want to have more cosmic planetary friends out there that maybe one day we'll be able to explore? By the latest accounts, there could be billions of Earth-like planets out there in our Milky Way galaxy.

Every year, October is designated as American Archive Month. While many people may think "archive" means only dusty books and letters, there are, in fact, many other types of important archives. This includes the use of archives for major telescopes and observatories like NASA's Chandra X-ray Observatory.

Less than 50 years after the first detection of an extrasolar X-ray source, the Chandra X-ray Observatory has achieved an increase in sensitivity comparable to going from naked-eye observations to the most powerful optical telescopes over the past 400 years. Many individuals have been involved in this phenomenal accomplishment, but in this contribution, we focus on one: Leon Van Speybroeck.

Leon was one of a number of newly minted MIT physics Ph.D.'s (including Paul Gorenstein, Martin Zombeck, Ethan Schreier, and one of us (HT)) who in the mid-late1960's made the short move from the MIT campus to the revamped milk-truck garage a few blocks away that was the site of American Science & Engineering. It was there that Riccardo Giacconi had assembled an X-ray astronomy group that had discovered the first cosmic X-ray source during a short rocket flight.
