For years astronomers have tried in vain to blow up an Earth-size star using strings of computer code. Finally, mission accomplished.

At just 23 years old, Barrington Irving strives to become the first African American and youngest person to fly solo around the world, clocking 130 hours of flight time during a four-continent sweep.

Mars is unlikely to sport beachfront property anytime soon, but the planet has enough water ice at its south pole to blanket the entire planet in more than 30 feet of water if everything thawed out.

In a cosmic game of pinball, black holes fling high-energy protons into space, where they zigzag around at near light-speeds before smashing into low-energy protons, finds a new study.

The gracefully flitting symphony of lights that color polar skies have their very own high-energy choreographer.

Two stellar titans are waging wind wars outside the Milky Way, and astronomers have the pictures to prove it.

Astronomers have measured the “layer-cake” structure of an extrasolar planet’s heated atmosphere.

Living up to its enchanting name, the Stardust mission has lugged back to Earth, well…real stardust, scientists announced today.

Astronomers are split over the merits of lunar-based observatories compared with those in free space like the Hubble Space Telescope.

Now that scientists have developed a blueprint for how the next generation of astronauts will whisk back to the moon, it's time to figure out what to do when they get there and why.

Astronomers have spotted 20 new star systems in our local solar neighborhood, adding to rapidly growing list of known stellar residents in our galaxy.

The stellar residents of jam-packed celestial cities employ a traffic system that causes lightweights to zoom to the city edges while keeping giants centrally located, conclude astronomers.

And exploded star named Cassiopeia blew up in such a way that it retained much of its original onion-like layering.

Astronomers have looked under the hoods of quasars, the brightest objects in the universe, and found some of the best evidence yet for the black holes that are thought to power them.

New images from a low-altitude Mars satellite are giving scientists some of their most detailed glimpses yet of the surface of the Red planet.

The energy output from the Sun has increased significantly during the 20th century. But scientits say it is not the key to global warming.
