Teleporting from one place to the next looks so fun on the big and little screen. But physicists who actually can do something like that with single atoms say teleporting people would be much messier.

Scientists with NASA's mission to Pluto revealed stunning new images of the dwarf planet on Friday. Researchers say the pictures suggest an icy world complete with glaciers and "snow" that falls through a wispy atmosphere.

The New Horizons spacecraft zipped past Pluto on July 14. It was traveling too ...

NASA is revealing the latest results from the Kepler Space Telescope, which was designed to hunt for planets around distant stars, including ones that might be Earth-like.

NASA's planet-hunting Kepler Telescope has spotted the first roughly Earth-sized world orbiting in the "Goldilocks zone" of another star – offering perhaps the best bet so far for life elsewhere in the universe.

A year on Kepler-452b, which is about 1,400 light years from us in the constellation Cygnus, is ...

Russian billionaire, Yuri Milner, has donated $100 million to the search for E.T. or extraterrestrial life.

Scientists have unveiled the best photos of Pluto and its moons that humanity is likely to see for at least a generation. These images were taken Tuesday by NASA's New Horizons space probe as it hurtled past Pluto at more than 30,000 miles per hour.

Since its discovery in 1930, ...

On Tuesday morning, NASA's New Horizons spacecraft swooped past the surface of Pluto. The vast distance between Earth and Pluto means they're still waiting to hear what happened.

Astronomers kicked Pluto out of the planetary club in 2006 because of its small size. But scientists set to explore the surface Tuesday via a spacecraft's camera say those other guys are just wrong.

NASA had a heart-stopping moment over the weekend, when engineers lost contact with a spacecraft they sent to Pluto. A computer crash was behind the problem.

After nearly a decade of traveling through space, NASA's New Horizons probe is about to arrive at Pluto. On Tuesday it will begin an intensive, weeklong study of the distant world.

After a string of launch failures, NASA says astronauts have just four months of supplies left. A Russian rocket launching early Friday could provide relief.

There is an extra "leap" second in Tuesday's clock. The second is designed to keep the clocks in synch with earth's rotation, but some people would like to take it away.

In Florida, an unmanned supply rocket blasted off for the International Space Station, but something went wrong. The loss of the rocket, which was also carrying experiments, is a setback for NASA.

New data from NASA's GRACE satellites show that many of the world's biggest aquifers are being sucked dry at a rate far greater than they are being replenished. Although scientists don't know how much water is left, they hope their findings will serve as a "red flag" for ...

A nonprofit has successfully tested technology that could one day be used to explore the solar system on a budget.

A competition in California is trying to ready robots for disaster response. But the bots have a ways to go.

Though past measurements have suggested global warming all but stopped in the late 1990s, newly refined figures show Earth's warming has continued unabated.

The chief disease agency in the U.S. is looking into why the spores shipped to laboratories in nine states and a military base in South Korea hadn't been properly neutralized. So far no one is sick.

A NASA spacecraft plunged into the planet Mercury on Thursday. It's demise comes after four years of studying our solar system's innermost planet.

Launched shortly after the fall of the Berlin Wall, the Hubble telescope isn't showing its age. Astronomers and other fans hope this old charmer will be useful for many years to come.
