New research suggests that some of Saturn's icy moons, as well as its famous rings, might be modern adornments. Their dramatic birth may have taken place a mere hundred million years ago, more recent than the era of the ...

It's tempting to think that the Moon never changes. You can spend your whole life looking at it, and see no evidence of change whatsoever. In fact, the ancients thought the whole Universe was unchanging. You may have hea...

Media are invited to see a NASA spacecraft that is safer on the ground and more efficient in space during a tour March 31 at Ball Aerospace & Technologies Corp. in Boulder, Colorado, showcasing NASA's Green Propulsion In...

In a nod to extraterrestrial mountaineers of the future, scientists working on NASA's Cassini mission have identified the highest point on Saturn's largest moon, Titan.

NASA Television will provide live coverage of the launch and docking of an unpiloted Russian cargo spacecraft, Progress 63P, to resupply the International Space Station.

The upper stage of the Atlas 5 that launched a Cygnus cargo spacecraft March 22 fired for more than a minute longer than planned, apparently to compensate for the premature shut down of the rocket's first stage engine. S...

Calculations by scientists have found highly magnetized, rapidly spinning neutron stars called magnetars could explain the energy source behind two extremely unusual stellar explosions.

New Horizons:

"The total mass I measured was much, much greater than the mass of the total number of stars--implying that there's a ton of densely packed dark matter contributing to the total mass," says Caltech astronomer Evan Kirby ...

Many of the crew's activities on Wednesday continued preparation for the arrival of Orbital ATK's Cygnus cargo craft, which launched successfully Tuesday night at at 11:05 p.m. EDT....

Even complex astrophysics is beautiful when seen as a "song of the stars."

"As explorers, we're motivated to find the highest or deepest places, partly because it's exciting. But Titan's extremes also tell us important things about forces affecting its evolution," said Jani Radebaugh, a Cassini...

Spaceplane, developed by Airbus Group, would send tourists to an altitude of 60 miles (100 km) above Earth.

Much of our Sun exists in the 'fourth state of matter:' plasma; more energetic than normal gasses. This plasma's viscosity and turbulence shapes our star's magnetic field.

Six hundred thousand years ago there was a colossal explosion from a cauldron of magma, the most massive known supervolcano, the 2.2 million acre Yellowstone caldera that forms the world's highest plateau capping a seeth...

A momentous signal from space has confirmed decades of theorizing on black holes—and launched a new era of gravitational wave astronomy --
