Deciphering the cratering history of the Moon is an important scientific problem. My previous post discussed early lunar cratering history, the apparent impact “cataclysm” 3.8 billion years ago, its significance to Earth’s early history and how remaining questions might be resolved by collecting a...

In the three years since film director James Cameron wrote the script for his new blockbuster Avatar, a lot has changed in the field of exoplanet research (the study of planets around other stars). Nobody knows this better than one of its leading practitioners, Lisa Kaltenegger of the Harvard-Smith...

In the novel 2001: A Space Odyssey, written as Stanley Kubrick was adapting it to a screenplay for his 1968 film, author Arthur C. Clarke philosophizes deeply on the convergence of man and machine. While the human astronauts Frank Poole and David Bowman affect an almost robot-like discipline and de...

Announcements of newly discovered planets come so frequently these days that it's hard to tell which ones are significant. But GJ 1214b deserves its moment of fame.Discovered by a team led by David Charbonneau of the Harvard-Smithsonian Center for Astrophysics, the planet is only 5.4 times the diam...

In 1982, the idea that a chunk of rock could be hurled from the moon to Earth by a lunar impact was considered pretty far out. For one thing, wouldn't such a massive, high-energy explosion destroy the evidence by turning the excavated rocks to glass? Besides, meteorites were well known to come from...

Sure it's pretty, and sure it boggles the mind, but maybe the most astonishing thing about the Hubble Deep Field image is that some scientists were initially against it. To quote from an article in our August/September 1996 issue:For Robert Williams, using the Hubble Space Telescope to peer deeply...
