April 9, 2013 Did the seeds of life on Earth begin on Mars? Are we part of Earth's first alien invasion? Adam Frank says we may be looking at a future full of discoveries in our own solar system that could reset our understanding of life and its origin.
February 19, 2013 The eye-popping, ear-splitting meteor streaking over Russia last Friday was an invitation to look up more often, to track the shooting stars we might see on any given night. These daily visitors to our planet put cosmic history into context, lighting up a past that is full of debris.
January 15, 2013 In a breathtaking video, astronauts talk of the Overview Effect: how their vision of the Earth — and our role in its future — changed once they saw it from space. It's high time we take their views seriously and act as a species to preserve our future.
December 18, 2012 Sub-surface water oceans and surface seas of liquid methane. The solar system just outside our doorstep is rich with possibilities. It's a voyage that astronaut-sailors will, one day, embark upon.
September 12, 2012 Our lives are based on conventions that seem rock solid when they aren't, at least in comparison with cosmic time-scales. The duration of a day changes in time, determined by the gyrations of the Earth-Moon pair.
September 10, 2012 New results from research by the University of Maryland and the Tokyo Institute of Tecnnology indicate that our solar system may, in fact, be quite unusual.
August 7, 2012 The Curiosity rover on Mars shows that, perhaps, we are ready to solve our problems. It shows us that we can face impossible challenges and find real, lasting solutions.
June 12, 2012 The sky is really, really scary. It's full of explosions, collisions and deadly cosmic rays. It's full of good reasons to develop a healthy dose of existential dread, something NYT columnist Maureen Dowd can relate to.
March 21, 2012 The sun's recent activity reminds us of of our cosmic fragility. How long do we have here until the "end"?
March 14, 2012 The sky this month is filled with wonders. A few centuries ago, people would be panicking, thinking the end was near. Now, we have reason to celebrate.
February 20, 2012 We are just at the beginning of this game of understanding how solar system architecture effects the chances for life (and complex life at that) developing. Part of this process will naturally involve having old assumptions challenged and, perhaps, overturned.
December 14, 2011 As modern science traces the steps from the big bang to intelligent life, the question of whether we are the rule or the exception leaps to the forefront.
November 29, 2011 How Many Planets Did We Start With?
