Satellites Show Warming Tides Melting a Massive Greenland Glacier

The finding could mean that past predictions of sea-level rise from glaciers should double

Dusty debris discs surround the young star Fomalhaut. The two innermost asteroid belts had never been seen before Webb revealed them.

James Webb Telescope Reveals Asteroid Belts Around Nearby Young Star

The findings suggest the star Fomalhaut may have orbiting planets hidden among its rings of debris

Using stereo cameras and lidar, EELS is able to create a 3D map of its surroundings, understanding the environment before navigating through it.

The star is on the cusp of exploding in a supernova and may offer insights into the universe's so-called "dust budget crisis"

After returning to Earth, EpiPen solution sent into space showed no signs of containing epinephrine, the life-saving drug that reverses the effects of a severe allergic reaction.

Kids Discover That EpiPens May Not Work in Space

After returning from space, the life-saving drug epinephrine had partially changed into poisonous benzoic acid

The astronauts launch into space at 12:34 a.m. Eastern time on Thursday. They'll join seven other astronauts aboard the ISS, before four others return to Earth in a few days. 

Four Astronauts Arrive at the International Space Station

Despite a launch delay and docking issue, the space travelers are now onboard the orbiting laboratory
