After more than two decades of drilling in Antarctica, Russian scientists have reached the surface of a gigantic freshwater lake hidden under miles of ice for some 20 million years — a lake that may hold life from the distant past and clues to the search for life on other planets.

A glimpse beyond our solar system reveals the neighborhood just outside the sun's influence is different and stranger than expected, scientists reported Tuesday....

Two years ago, scientists at the National Center for Atmospheric Research in Boulder, Colo., released a study claiming that inconsistencies between satellite observations of Earth's heat and measurements of ocean heating amounted to evidence of "missing energy" in the planet's system.

Scientists are confirming a recent and rare invasion from Mars: meteorite chunks from the red planet that fell in Morocco last July. This is only the fifth time scientists have chemically confirmed Martian meteorites that people witnessed falling. The small rock refugees were seen in a fireball in the sky six months ago, but they weren't discovered on the ground in North Africa until the end of December.

Firing on all engines, NASA's latest rover to Mars executed a course adjustment Wednesday that put it on track for a landing in August.

Scientists detect two distant worlds they think are the roasted remains of once giant planets that became engulfed by their parent star.

A NASA rover scouting for signs of past water on Mars has found the strongest evidence yet -- a vein of gypsum, a mineral deposited by water, protruding from an ancient rock.

The most Earth-like planet ever discovered is circling a star 600 light years away, a key finding in an ongoing quest to learn if life exists beyond Earth, scientists said on Monday. "We are homing in on the true Earth-sized, habitable planets," said San Jose State University astronomer Natalie Batalha, deputy science team lead for NASA's Kepler Space Telescope that discovered the star.

Don’t get too close. Astronomers are reporting that they have taken the measure of the biggest, baddest black holes yet found in the universe, abyssal yawns 10 times the size of our solar system into which billions of Suns have vanished like a guilty thought. Such holes, they say, might be the gravitational cornerstones of galaxies and clues to the fates of the violent quasars, almost supernaturally powerful explosions in the hearts of young galaxies, that dominated the early years of the universe.

The one-ton, car-sized Curiosity rocketed from Kennedy Space Center Saturday. The vehicle is on a two-year mission to determine whether life could have existed on Mars.
