Scientists unveiled the largest 3D map of the universe ever, showing its expansion rate over 11 billion years.

NASA combined 10 years of solar observations into a single, gorgeous time-lapse video.

Using thousands of seismic wave recordings, researchers mapped the mysterious 'blobs' deep below the Pacific Ocean and found they are even bigger than imagined.

Twin shock waves produced by the galaxy's central black hole could have inflated the gargantuan Fermi Bubbles about 6 million years ago, a new study suggests.

Researchers figured out why this galaxy looks like an enormous X in invisible radio light.

Photographer Andrew McCarthy photographed the demarcation between the moon's light and dark sides for two weeks to create this unbelievably crisp image of our satellite's Earth-side craters.

An unusually strong polar vortex kept an ozone hole open over the North Pole for nearly a month — now, it's finally shut again.

The alleged exoplanet Fomalhaut b was discovered in 2004 and disappeared in 2014. Astronomers now say it was never a planet to begin with.

A record-size hole in the ozone layer has been detected over the North Pole, but it should disappear in a few weeks.

In six studies published March 16 in a special edition of The Astrophysical Journal supplemental series, astronomers used NASA's Hubble Space Telescope to spy on 13 quasar outflows.

Researchers discovered an uncharted island beneath melting Antarctic ice. Its rocky underbelly could hold clues to the continent's response to climate change.

Astronomers discovered a 'minimoon' that's been orbiting Earth for about three years, and may soon leave our planet's orbit.

Antarctica saw two record-high temperatures set between Feb. 6 and Feb.9, and that took a huge toll on the continent's ice, as seen in NASA images.

A huge chunk of ice twice the size of Washington, D.C., just broke off of Antarctica's Pine Island glacier, continuing a troubling trend that could signify glacial collapse.

Solar super-storms capable of damaging electric grids and satellite networks may be much more common than previously thought, a study of Earth's oldest geomagnetic index suggests.

Astronomers uncovered a pair of invisible stars creating ripples in space-time, a phenomenon known as gravitational lensing.

There's a faint gamma-ray background in the universe, and scientists now think it could be caused by dark matter.

The US Navy confirmed they have secret, classified documents regarding a 2004 UFO encounter, but releasing them could 'gravely damage' national security.

Three galaxies 13 billion light-years may be ending the cosmic 'dark ages' before our eyes.
