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.

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.
