The Trifid Nebula - a potential analog for the kind of place our Sun was formed in 4.5 billion years ago (NASA/ESA) In lieu of a proper post I thought I'd link to a recent video courtesy of SpaceLab at YouTube...
The "Hottah" rock outcrop, an ancient stream or river bed (NASA/JPL-Caltech/MSSS) It's one thing to spot stuff from orbit above an alien world, quite another to get in close.E..
Tweet it to the stars (well, GJ667C to be precise) A while back I wrote about a wonderful piece of art-meets-science-meets-the-public called Tweets In Space, the brainchild of Nathaniel Stern and Scott Kildall...
Spinning black hole (NASA) Black holes, black holes, and more black holes. In the past few weeks I've been thinking, talking, and even dreaming about black holes (yes really, somnolent thoughts seem well suited to these fantastic objects)...
Peekabo! Mastcam seen by the MAHLI camera on Curiosity's arm (NASA/JPL-Caltech/MSSS) There is nothing particularly scientific about this image, but it is remarkably evocative.

Ok, so every so often something comes along that just blows away everything you've seen before. This is one of those things. Soon after Curiosity made landfall we got to see a glimpse of a low-resolution and highly compressed time-lapse video of the descent, showing the heat-shield fall away and a precipitous drop to the martian surface...
It's all about origins... Another couple of episodes in Bishop Sands' outstanding Sift podcast series on origins and life are now up. You can catch my verbal contribution on interstellar chemistry at about the 11 minute mark in this one (below) on Origin Stories, but I encourage you to listen to the whole thing...
This post is the fourth in a series that accompanies the publication of my book ‘Gravity’s Engines: How Bubble-Blowing Black Holes Rule Galaxies, Stars, and Life in the Cosmos’ (Scientific American/FSG)...
The clock is ticking and NASA's Curiosity rover with its burden of the Mars Science Laboratory is heading for a potentially historic landing on Mars.
