NASA Goes Big and Bold for Exoplanet Science
A United States federal agency is not necessarily the first place you think of when it comes to answering some of the deepest existential questions for our species...

A recent article by Samuel Arbesman in the science magazine Nautilus discusses the extraordinary sounding possibility that – just perhaps – a search for extraterrestrial intelligence could be made by looking at our DNA...
In an idle moment, while staring at a set of solar system data, it occurred to me that it might be interesting to display a set of planetary surfaces on an equal footing, where the overall texture of these worlds was visible (although topography is probably a more [...]..
It's been a long time coming, but this week NASA's Mars Opportunity rover completed the first-ever Martian marathon. After landing on the Red Planet in January 2004 on a mission originally planned to only last 90 days, Opportunity has instead endured for more than a decade, and has taken eleven years and two months to [...]..
What I love about the annual TED gathering in Vancouver is the way science coexists along with art, social justice, popular song and the rest of TED's eclectic mix.
Whether it is waiting to hear about draft picks or the next release by Apple, there are many things that make enthusiasts hold their breath.
Astrobiology has one key advantage when it comes to tooting its own horn – it can lay claim to a diverse range of scientific research as being relevant to the study of life in the universe...
NASA’s new space station mission is not a big step toward Mars, but mostly a holding pattern
Ever since President George W. Bush's decision to retire the space shuttles in the aftermath 2003's Columbia disaster, NASA's human spaceflight program has been adrift.
Picture a hot volcanic spring. Mineral-laden acidic water flows through sulfur-rich rocks. A foul odor hangs in the air. For us it’s a nasty environment, best enjoyed through the lens of a tourist’s camera...
Quite often when I am looking at photos, I just feel like something is missing. It is not a criticism of the light or the composition, but rather that something is, quite literally, missing: a scale...
Lost, presumed crashed, the Beagle-2 lander is finally located on Mars. Back in December 2003 a bold and decidedly British robotic device was released from the European Space Agency’s (ESA) Mars Express orbiter...
Probably not, but just possibly yes. One of the reasons that the search for life elsewhere in the universe is so exciting is that it would take only one chance discovery, one lucky break, for all the walls to come tumbling down...
From humanity’s first, flawed foray to the surface of a comet to the celebrated discovery of (and less celebrated skepticism about) primordial gravitational waves, 2014 has brought some historic successes and failures in space science and physics...
Two billion year-old water pockets and a revised deep hydrogen content are good news for Earth’s vast subsurface biosphere, and could offer clues to life on Mars and much further beyond...
The first human-rated U.S. spacecraft since the space shuttle took an unmanned trial run on Friday
822 Martian days after landing, NASA’s Curiosity rover, carrying the Mars Science Laboratory, continues on its extraordinary journey across landscapes that are both utterly alien, and remarkably familiar...
Today marks the 50th anniversary of the launch of NASA’s Mariner IV spacecraft (November 28, 1964). In total, the mission gave us 21 complete images of Mars, including this, our first close view of the planet—courtesy of data transmitted by the interplanetary probe and earth-bound scientists wielding pastels (below)...
The skies of Mars just got a little more crowded. On September 21st, 2014 NASA’s Mars Atmosphere and Volatile Evolution Mission (MAVEN) fired its engines for some 33 minutes in order to swing into a safe orbit...
NASA’s MAVEN orbiter arrived at Mars to study how gas escapes from around the planet
