A giant asteroid will make a flyby of Earth over the next few days, and armchair astronomers can watch the action live on their computers.

Attention wealthy nations and billionaires: A team of former NASA executives will fly you to the moon in an out-of-this-world commercial venture combining the wizardry of Apollo and the marketing of Apple. For a mere $1.5 billion, the business is offering countries the chance to send two people to the moon and back, either for research or national prestige. And if you are an individual with that kind of money to spare, you too can go the moon for a couple days.

Science editor Alan Boyle's blog: Although NASA's Curiosity rover hasn't yet confirmed the detection of organic compounds on Mars, it's already seeing that the Red Planet's soil contains complex chemicals, including perchlorate.

Just in time for Christmas, scientists have confirmed a vast amount of ice at the north pole - on Mercury, the closest planet to the sun....

NASA and Russia's Roscosmos have named the two men who will spend a year aboard the International Space Station to gather more data about the effects of weightlessness on humans....

Curiosity is living up to its name. The NASA rover currently wheeling itself around Mars has apparently sent back some very interesting data from the Red Planet in the form of a soil sample that shows ... well, something. From the sounds of it, something big. But for now at least, that's all anyone is willing to say.

There’s an orphan planet roaming our galactic neighborhood. It’s a globe of gas about the size of Jupiter, astronomers say. And it’s out there by its lonesome, untethered to any star, drifting about 100 light-years from Earth. (In astronomical terms, that’s close.)

NASA's Curiosity rover reports confirmation that Mars has lost at least half of its early atmosphere.

Wow, what a view of the Curiosity rover! This is a self-portrait mosaic made from brand new images taken by the MAHLI (Mars Hand Lens Imager), the high-resolution camera located on the turret at the end of MSL’s robotic arm. The arm was moved for each of the 55 images in this mosaic, so the arm doesn’t show up in the mosaic. This montage was put together by Stuart Atkinson, and he notes that these images are just the low-res thumbnail images that have just been sent to Earth. “Imagine what the hi-res version will look like!!” Stu said.

Using NASA's Fermi Gamma Ray Space Telescope, scientists were able to detect the light of the earliest stars, which are now long since gone... One of the primary goals of the Fermi Gamma Ray Space Telescope is to measure the starlight in the universe and use that to figure out how much light has ever shone in it. Yesterday, astronomers on Fermi’s research team announced that they have reached that goal.
