A special device aboard the International Space Station has produced Bose-Einstein condensates in space for the first time ever.

The technology could improve future precision light sources. But right now the biggest surprise is how many holes there are in a laser figure-eight.

Australian amateur astronomer Tom Harradine made an image of the century's longest lunar eclipse that reveals the true scale of the Earth's dark umbra.

If Earth suddenly turned into an Earth-size pile of blueberries, things would start exploding. This is science.

The Large Hadron Collider accelerated lead nuclei with orbiting electrons along its tunnel for the first time, opening new scientific doors.

Atomic clocks have traveled to space before. But no one has ever managed to make one this accurate tick up there before.

A new paper opens a door to the possibility of life having maybe once existed, possibly, on the moon. But it presents no direct evidence for life.

Researchers for the first time recorded the gas giant's vibrating plasma signal to Enceladus. And now you can listen to it too.

A report from Xingfu, China, may point to the source of a bizarre spike in ozone-layer-depleting CFCs reported in May.

The universe's missing baryons have been found, and they're floating between the stars in the form of superhot oxygen.

The physicist's remains will be interred at Westminster Abbey between those of Isaac Newton and Charles Darwin. Meanwhile, his voice will stream through space.

When the baby bird invaded the telescope scientists scrambled to make sure it wouldn't damage sensitive optics (or hurt itself).

NASA did find two more scraps of evidence about the kind of life that might exist on Mars. Here's what the new research really shows.

The Higgs boson appeared again at the Large Hadron Collider (LHC), and this time, it revealed something new and exciting about its behavior.

There's something strange happening in the universe, and it's either evidence of a hidden particle, or a sign that the experiments are broken.

The Large Hadron Collider hasn't found any new physics since the Higgs boson. A team of outsider physicists think they know why.

NOAA's GOES-17 was supposed to watch for deadly storms and dust clouds in the Western Hemisphere. Instead, it's spending half the day blind.

Scientists can't explain why in the world someone would decide to pump out the dangerous gases again.

Pulses of light from infrared lasers can speed up computer operations by a factor of 1 million, and may have opened the door to room-temperature quantum computing.

The great physicist's library of work is now complete.

What size is a pulsar?

This new experiment is a huge example of the behavior Albert Einstein called "spooky action at a distance."

A Twitter user managed to turn 25 minutes worth of images from the ESA's comet lander into a dramatic short film.

NASA scientists flying over the arctic earlier this month spotted strange shapes out the window, but they aren't sure what caused them.

A bunch of very big corporations and rich men, including Bill Gates, are hoping to start watching the whole Earth at all times with video cameras in outer space.
