Discussion and news about planets, exoplanets, and astrobiology
Northern polar ice cap of Mars (NASA/Mars Global Surveyor) Let's get something clear right away, Mars has lots of water on and close to its surface. Over the years we've seen an increasing number of measurements and discoveries that indicate very significant reservoirs of martian water...
Juno and Jupiter (NASA/JPL) Another quick refurbishment from the archives, this one about the Juno mission to Jupiter. With any luck in a few hours Juno will launch and be on its way, arriving at Jupiter in 2016...

Light or heavy? The nuclear choice On the heels of #SciAmChem day I thought I'd pull a post from the Life, Unbounded archives that could use a little airing and has a chemical slant...
“We are starstuff”, it’s a well-used phrase in popular astronomy (yes, we are. The nuclei of most heavy atoms in your body were forged long before our solar system existed, a million kilometers down inside the cores of long-since-gone massive stars)...
Imagine a molecule... "We are starstuff", it's a well-used phrase in popular astronomy (yes, we are. The nuclei of most heavy atoms in your body were forged long before our solar system existed, a million kilometers down inside the cores of long-since-gone massive stars)...
Vesta up close (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA) It's an exciting time for solar system exploration. NASA's Dawn mission has now entered into an orbit around the minor planet known as Vesta, a 500km diameter chunk of rock and who-knows-what-else that orbits the Sun beyond Mars and in the classical asteroid belt...
These are two posts from the Life, Unbounded archives. They were written in April and May 2010. Around that time there was a lot of media noise about aliens - brought on in part by Stephen Hawking's comments about fearsome "nomadic" lifeforms that might roam the universe...
Shuttle mission STS-118 (NASA) This is not exactly the normal kind of post on Life, Unbounded , but there's good reason for it.Our species of peculiarly upright, lurching, yabbering, fidgeting, opposing thumb creatures has managed to claw its way through time to arrive at a very special point...
Storm on Saturn (Credit: NASA/JPL-Caltech/SSI) Oh weather; a joy, a pain, the making of a beautiful day or a miserable evening. Our planetary environment is constantly shuffling through a deck of thermodynamic cards and local conditions reflect a small part of the resultant lofting, pouring, steaming, streaming and meandering of atmospheric contents...
