Although the Kepler spacecraft's primary mission came to an end when the second of four reaction wheels used to stabilize the spacecraft failed, scientists have come up with an ingenious strategy to control Kepler and use it in a new mission.
Astronomers may have found the "perfect storm" for ending star formation.
It turns out that there's been a steady increase in the absorption of solar radiation by the Arctic. Now, NASA satellite instruments are revealing a bit more about this absorption.
The ESO Cosmic Gems program is coming out with some spectacular images. And it's not all that surprising that Messier 47 is the target of one of these images. This open cluster sports bright, hot blue stars that shine against the backdrop of space.
Each year, holiday lights go up throughout the United States and the nights become just a bit brighter for it. But you don't just see these lights here on Earth; you can also see them from space.
It turns out that the closest planet to our sun is periodically hit by a meteor shower, and this shower may be associated with a comet that produces multiple events annually on Earth.
NASA's Curiosity rover has made a startling discovery. It's found the first organic molecules on the Red Planet. The findings could mean that there was once life on the planet--or could simply be the result of chemical reactions.
How severe is California's drought? That's a good question. Now, scientists have examined exactly how much water would be needed to recover from the drought, and the results are less than optimistic.
These days, Mars doesn't have much in the way of an atmosphere. And yet it did in its ancient past. Now, NASA's newest Mars orbiter, MAVEN, has discovered key features about the loss of the planet's atmosphere to space over time.
The Earth's most abundant mineral family finally has a name. Scientists have used an ancient meteorite and high-energy X-rays to find, identify and characterize a mineral that makes up about 38 percent of our planet.
It turns out that NASA's Voyager 1 spacecraft is still experiencing the "tsunami wave" that it began earlier this year. The findings mean that this is the longest-lasting shock wave that researchers have seen in interstellar space to date.
