Sometimes images arrive that make it clear that the space age is not a throw-away line, but a reality. This one was taken by a satellite orbiting Mars, and it shows the Earth and the moon. Kind of remarkable, given that the camera -- the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars …
Some Spectacular Images (And Science) From The Year Past
This is a golden era for space and planetary science, a time when discoveries, new understandings, and newly-found mysteries are flooding in. There are so many reasons to find the drama intriguing: a desire to understand the physical forces at play, to learn how those forces led to the formation of Earth and ultimately us, …

Curiosity Has Found The Element Boron On Mars. That’s More Important Than You Might Think
For years, noted chemist and synthetic life researcher Steven Benner has talked about the necessary role of the element boron in the origin of life. Without boron, he has found, many of the building blocks needed to form the earliest self-replicating ribonucleic acid (RNA) fall apart when they come into contact with water, which is …

The Search for Organic Compounds On Mars Is Getting Results
One of the primary goals of the Curiosity mission to Mars has been to search for and hopefully identify organic compounds -- the carbon-based molecules that on Earth are the building blocks of life. No previous mission had quite the instruments and capacity needed to detect the precious organics, nor did they have the …

The Stellar Side of The Exoplanet Story
When it comes to the study of exoplanets, it's common knowledge that the host stars don't get much respect. Yes, everyone knows that there wouldn't be exoplanets without stars, and that they serve as the essential background for exoplanet transit observations and as the wobbling object that allows for radial velocity measurements that lead …

SETI Reconceived and Broadened; A Call for Community Proposals
Earlier this summer, Natalie Cabrol, the director of the Carl Sagan Center of the SETI Institute, described a new direction for her organization in Astrobiology Magazine, and I wrote a Many World column about the changes to come. Cabrol's Alien Mindscapes – Perspective on the Search for Extraterrestrial Intelligence" laid out a plan for the new …
