The Antarctic ice is finding its secrets harder and harder to keep. → Read More

There Are Tiny Bright Dots All Over The Sun, And We May Finally Know Their Source

Sunspots aren't the only speckles decorating the dynamic face of our Sun. Solar physicists have made a close study of tiny, fleeting speckles of brightness that emerge and fade in less than a minute on average, in regions where loops of plasma rise f → Read More

These Eerie Wails Are a Real Sound Wave From a Supermassive Black Hole

We might not be able to hear sound in space, but that doesn't mean there isn't any. In 2003, astronomers detected something truly astonishing: acoustic waves propagating through the gas surrounding a supermassive black hole, 250 million light-years a → Read More

Several 'Echoing' Black Holes Have Just Been Discovered in The Milky Way

Echoes of light bouncing off thick clouds of material around active black holes are helping astronomers better understand the wacky space-time in the immediate vicinity of these extreme objects. → Read More

Tiny crystals of zircon dated to 3.8 billion years ago contain the earliest geochemical evidence yet for plate tectonic activity here on Earth. → Read More

Venus Should Be 'Locked' With One Side Facing The Sun. Here's Why It Isn't

When two bodies in space are close together enough, their gravity acts as a brake, slowing them until one's rotation 'locks' to match its orbit. → Read More

Look at This Epic NASA Backpack Designed For Astronauts on The Moon

Human explorers on the Moon may be able to send back unprecedented, finely detailed maps of the lunar surface, thanks to a new backpack device developed by NASA and its partners. → Read More

A newly discovered type of stellar explosion could help us better understand thermonuclear outbursts on dead stars. → Read More

Scientists Want to Send a NASA Probe to Uranus as a Major Research Priority

Uranus has been sadly neglected. Probes have visited Mars, Venus, Saturn, Jupiter, and Mercury. Heck, even Jupiter's moons are getting their own spacecraft. But the ice giants Uranus and Neptune, in the distant reaches of our Solar System, have not h → Read More

One of The Solar System's Best Candidates For Alien Life Has Signs of Liquid Water

Strange double ridges on the surface of Jupiter's ice moon Europa could be signposts to shallow reservoirs of water. → Read More
