- After 7-1/2-hour installation, space station cooling pump passes tests
Astronauts earn Christmas off after installing the cooling pump with their second spacewalk. Mission controllers hope to have the station running at full capacity by week's end.
- Winter solstice 2013: Were you really waiting until now for winter?
Winter solstice 2013: The sun is lowest, the night is longest, the (Northern Hemisphere) winter solstice is here, and so is winter. Unless, of course, you take your cues from the weather, and you're three weeks in already.
- Asteroid-hunting telescope orbiting Earth sends first images, with clarity
NEOWISE, an infrared telescope orbiting Earth, returns test images in preparation for hunting and characterizing near-Earth objects, especially asteroids. The information it provides will help scientists gauge the hazard different asteroids pose.
- DARPA Robotics Challenge opens in Florida
Seventeen of the world's most sophisticated humanoid robots will compete in eight trials in one arena.
- Little island that could: Japan's newest island is growing
Japan's new island was seen in a NASA satellite image, defying expectations that it would fast erode and disappear back into the water.
- Massive leap in search for habitable planets
Pinning down the mass of exoplanets has been problematic, but it is central to determining if a planet might be habitable. Now, a new method could help scientists 'a lot.'
- China to bolster presence in Antarctica, build fourth research station
China is expanding its presence in the resource-rich continent, a possible sign that it could be gearing up for a power play in future negotiations over how to manage the region's oil and minerals, analysts say.
- Gaia satellite to chart one billion stars, answer cosmic questions
What can the Gaia satellite, launched on Thursday, tell us about the past, present, and future of our galactic neighborhood? The new satellite carries a billion-pixel camera that will furnish the largest ever 3D map of the Milky Way.
- Christmas Day spacewalk? Astronauts will go outside to fix space station.
Astronauts aboard the International Space Station are now scheduled to conduct three spacewalks to replace a malfunctioning coolant pump on the station's exterior.
- Neanderthal genome suggests new, mysterious human lineage
A genome sequenced from the toe bone of a Neanderthal woman has yielded several new insights into the evolution of early humans and their contemporaries.
- Two US astronauts tapped for spacewalks to fix a space station pump
NASA has scheduled three 6-1/2-hour emergency spacewalks, starting Saturday, aimed at repairing a faulty cooling pump aboard the International Space Station.
- How many arms does The Milky Way have?
The Milky Way is more like a Hindu god than a human, according to a new galactic map that has revised how scientists look at the Milky Way's appendages.
- Watch out, Rudolph: Climate change endangers reindeer games
Reindeer habitats are shrinking in the face of global climate change. While some pockets will survive, their genetic diversity and ability to withstand change is vulnerable, say scientists.
- Space station may need emergency spacewalk if software patch fails
A faulty pump means the space station might have to scrap a scheduled resupply to perform an emergency spacewalk. NASA hopes a temporary fix will allow the resupply to go ahead.
- China touts prowess of moon rover, scientists just want to know what's there
China has sent its Jade Rabbit rover to a lunar crater with rocks far younger than any explored by the US or Russia. Its findings could help piece together a little-understood period in the moon's history.
- Study finds evidence of domesticated Chinese cats 5,300 years ago
An analysis of feline remains at an archaeological site in China suggests that cats were domesticated there much earlier than previously thought.
