SUNSET: 
A Breathtaking View of Titan

Kepler Finds Two "Deep-Fried" Planets
The incredibly successful Kepler spacecraft is discovering alien solar systems at a dizzying pace. Now it's found a system in which two planets have apparently survived a journey inside their host star, during its swollen red-giant phase.
NASA Taps a Rocket Scientist
With probes on the way to the Moon, Mars, and Pluto — and a multibillion-dollar space telescope gobbling up shrinking funds — astronomer and former astronaut John Grunsfeld agrees to take the helm of the space agency's science division.
Asteroids, Planets, and Moons, Oh My
This week’s meeting of the American Geophysical Union brought together a variety of interesting science results, from water on Mars to the Sun’s effect on the Moon’s surface. Here’s a selection of curiosities for your perusing pleasure.
Kepler Finds a Possibly Habitable World
The hits just keep on coming for NASA's Kepler spacecraft. Today mission scientists announced that they've identified a thousand more candidate planets around other stars. One is Kepler-22 b, a world somewhat larger than Earth where you likely could walk around in shirtsleeve temperatures.
Voyagers Detect Missing Signal
The Voyager spacecraft have observed long-sought emission from the Milky Way while traveling through the outermost reaches of the Sun’s influence.
“Sayonara” to Akari Space Telescope
Japanese ground controllers have pulled the plug on a little-known but highly productive space telesocpe that revealed the far-infrared universe as never before.
Curiosity Heads for Mars
NASA's latest interplanetary mission seeks to put a one-ton rover on the Martian surface. With Saturday's picture-perfect launch, Curiosity is safely on its way.
EPOXI Offers Do-It-Yourself Imagery
Try your hand at processing raw images of deep-sky object taken by NASA's EPOXI spacecraft.
Phobos-Grunt's Sad Fate
Russia's first mission in 15 years from a once-proud interplanetary program has ended in failure, as a spacecraft intended to land on a Martian moon was unresponsive and stuck in orbit around Earth after launch, which doomed it to atmospheric annihilation two months later.
Ready for Rosat's Reentry?
Sometime within the next week, perhaps on Sunday, a defunct German astronomy satellite will fall from orbit and drop a 1½-ton cosmic cannonball — its telescope assembly — somewhere on Earth.
Is Mercury Alive After All?
The Messenger spacecraft has discovered unusual hollow formations on Mercury's surface. No one knows what causes them, but volatile-spewing volcanoes are candidates.
Mercury Shows Its True Colors
After six months of studying the innermost planet with NASA's Messenger spacecraft, planetary scientists are discovering unexpected surface compositions and are finally zeroing in on how the innermost planet came to be.
One Image, Five Moons
A quintet of Saturn's moons come together in the Cassini orbiter's field of view for a group portrait.
GRAIL Heads for the Moon
By this time next year, the twin spacecraft of NASA's Gravity Recovery and Interior Laboratory mission should have given geophysicists an unprecedented peek at the lunar interior from crust to core.
Opportunity Reaches Its New Home
The surviving one of NASA's two Mars Exploration Rovers is reaching the brink of a whole new adventure on Mars.
Juno Lifts Off for Jupiter
NASA's solar-powered spacecraft Juno successfully lifted off Cape Canaveral on Friday, August 5th.
Where No Spacecraft Has Gone Before
Dawn sends stunning images from Vesta of an uncharted alien world.
Kepler's Dilemma: Not Enough Time
NASA's planet-hunter has already identified more than 1,200 exoplanet candidates. But project managers now quietly acknowledge that the spacecraft will have serious difficulty spotting habitable, Earth-size worlds by the mission's end next year.
Next Mars Rover Targets Gale Crater
When NASA launches the multibillion-dollar Curiosity rover toward Mars in November, it'll make a beeline for the floor of a large crater that geologists say once brimmed with liquid water.
