After 10 years of travel and three months orbiting the comet 67p/Churyumov-Gerasimenko, the European Space Agency's (ESA) Rosetta spacecraft is poised to deliver its landing probe, Philae, to the comet's surface -- a first in history.
Part 2 of the TED Radio Hour episode How It All Began. About David Christian's TED Talk David Christian explains the history of the universe from the big bang, and how humans occupy little more than a millisecond on that cosmic timeline. About David Christian David Christian is a historian ...Read More
NASA's latest mission to Mars, MAVEN (Mars Atmospheric and Volatile Evolution), entered Martian orbit less than a month ago on September 21. It's already rewarded us with revealing insights into the disappearance of Mars' atmosphere.
In the wee morning hours of Wednesday, October 8, a total lunar eclipse will occur, delighting anyone of the lucky side of the Earth willing to set their alarms extra early.
This Sunday night, we headed back to Mars: NASA's MAVEN spacecraft fired its six main engines, slowing down enough so it could be captured by the gravity of the red planet and go into orbit. MAVEN, which stands for Mars Atmosphere and Volatile Evolution, is a distinctly un-sexy name for a ...Read More
Curiosity has reached the base of Mount Sharp, its primary mission goal. It's a 3-mile-high mound of sediment that preserves a geologic record of Mars going back billions of years.
On September 21, NASA's MAVEN (Mars Atmosphere and Volatile Evolution) spacecraft will go boldly where no one has gone before: to the very top of the Martian atmosphere!
The European Space Agency’s (ESA) Rosetta has reached its target -- the Comet 67p/Churyumov-Gerasimenko -- becoming the first spacecraft in history to rendezvous with a comet.
One of NASA's most senior and still-operational spacecraft reached a milestone: the rover Opportunity completed its first 25 miles traveling across the surface of Mars!
Europe's Rosetta mission is poised to add another extraterrestrial landfall to a very short list, and top a new list as it becomes the first mission to land a probe on a comet.
A decade ago, NASA's Cassini spacecraft, the largest and most complex robotic probe yet built, arrived in the Saturn system to begin a marathon exploration of the gas giant, its famous and awe-inspiring rings and what has turned out to be a collection of some of the most eye-opening moons in the solar system.
The data could yield a much more precise picture of how accumulating greenhouse gases will affect the planet.
Will the generation that is coming into the world today know more than eight, more than nine, solar planets? Some recent observations make this prospect sound like a strong possibility.
As a flood of new exoplanets swim into our ken, we have ways of turning these pixel-size steams of data into insights about our own planet.
How big can an Earth-like planet be? Astronomers thought they had a pretty good handle on this question but have just been given a fresh example of how nature never ceases to outpace our imaginations and show us something unexpected.
Recently, a major milestone in space exploration was reached: a planet was captured in a picture! The big deal is that the planet captured in this shot, a gas giant planet named Beta Pictoris b, is 63 light years away--over 100,000 times farther away than even Pluto.
The May Camelopardalids, named after the 'camel leopard' constellation, might be phenomenal. ...Read More
