Astronomers trawling through a mess of stellar data discover that Tau Ceti, our nearest single Sun-like star, hosts five planets - one in its "habitable zone".

At 5:28 p.m. Monday, NASA’s Grail spacecraft will crash into the Moon’s shadows. (What would you call the half of the Moon facing away from the Sun?)

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.

The military's small, top-secret version of the space shuttle rocketed into orbit Tuesday for a repeat mystery mission, two years after making the first flight of its kind. The Air Force launched the unmanned spacecraft Tuesday hidden on top of an Atlas V rocket. As if on cue, clouds quickly swallowed up the rocket as it disappeared out over the ocean.

It sounds like the plot of a bad Bruce Willis movie, but some experts are saying it should be a reality. In order to prepare for massive asteroids that could aim for Earth in the future, researchers should ram a spaceship into a real asteroid to see if the space rock would shift course, scientists say.

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.

That wonder molecule of life on Earth, DNA, is now being enlisted in the search for an exotic species zooming through the cosmos: dark matter... As far back as the 1930s, astronomers watching distant galaxies saw that something was missing: There were not enough stars to account for the heavy gravity needed to whirl galaxies so quickly or smash them together so swiftly.

The Voyager 1 spacecraft is traveling through a previously unknown region of deep space as it heads out of our solar system, which might happen soon, scientists reported Monday. Voyage and its twin, Voyager 2, were launched in 1977 and will become the first man-made objects to exit our celestial neighborhood -- relatively soon.

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....
