Red dwarf stars have several virtues that make them potential homes for Earth-like planets, but a new study suggests they also produce the largest solar flares ever seen.
British scientist Simon Conway Morris believes there are only two possibilities for alien life; either we're alone or aliens exist, and they are out to get us.
For the first time, scientists have confirmed an exoplanet that is rocky like Earth – not a gas giant. It's also 2,500 degrees F and denser than iron, so it's no candidate for life, say members of the team working with the planet-hunting Kepler spacecraft.
The planet Kepler-10b, spotted by NASA's planet-hunting space telescope, is just 1.4 times larger than Earth.
Five US cities – Boston, Providence, R.I.; Hartford, Conn.; Concord, N.H.; and Caribou, Maine – broke temperature records in 2010, a new report has found.

Orange alligator: An orange alligator was spotted in Venice, Fla., Wednesday. Experts say the color is not genetic.
Aflockalypse: Despite alarming headlines about dead birds plummeting from the sky, biologists say that mass die-offs happen all the time, and do not necessarily augur catastrophe, either biblical or environmental, or any kind of 'aflockalypse.'
Crab Nebula has provided astronomers with a steady presence in space. But, as recently as last September, gamma-ray flares emanated from the famous Crab Nebula, causing scientists to reconsider the burial ground of a dead star.
A team of researchers has released a study chronicling the steep decline of some bumble-bee species in North America. The findings are called an 'environmental warning'.
Some 25,000 dead velvet swimming crabs have washed ashore on England's Thanet Coast. Similar mass die-offs of the crabs have occurred the past three years.
Scientists have discovered a prehistoric flightless bird whose wings evolved into massive curved weapons.
A 10-year-old Canadian girl became the youngest person ever to discover an exploding star, or supernova.
Solar Eclipse: In Rome, cloudy skies made the Jan. 4 solar eclipse a touch eerie as the moon appeared to take a bite out of the sun during the three-hour eclipse.
The first solar eclipse of the year will be a partial one that occurs Tuesday morning.
Meteor shower tonight: The first meteor display of 2011 – the annual Quadrantid meteor shower – will hit its peak tonight, weather permitting.
This week will see a lesser known meteor shower, the Quadrantid, dazzle the night sky on Jan. 3 and 4. It's the first of nine significant meteor showers in 2011. Here’s a list of all the events and what to watch for each time.
