The spinning magnetar transferred a remarkable amount of energy to the debris created by the collision, heating the material up and generating a bright glow.

In a First, Astronomers Witnessed the Birth of a Supermassive Magnetar Following a Glorious Kilonova

The scientists originally thought that the cosmic crash would create a black hole

Astronaut Luca Parmitano uses a sample-spinning centrifuge on the I.S.S. to expose the bacteria to the equivalent of Mars' gravity.

Laboratory tests reveal that ice blocks containing different salts glow differently after being exposed to radiation.

Radiation Might Make Jupiter's Salty, Icy Moon Europa Glow

Europa is one of Jupiter's four largest moons and a prime candidate for finding life beyond Earth

This artist's rendering shows the OSIRIS-REx spacecraft descending towards asteroid Bennu to collect a sample.

NASA Snags Its First Asteroid Sample

On a mission more than 200 million miles away from Earth, the OSIRIS-REx spacecraft grabbed rocks from Bennu

This visualization shows the merging of two black holes, which emit gravitational waves.

Scientists Are Detecting More Gravitational Waves Than Ever Before

The LIGO and Virgo teams have spotted 50 total cosmic signals since 2015

Scientists have known about ice in the dark, deep craters at the moon's poles, some of the coldest known places in the universe, but voyaging into one just wouldn't be likely.

The Moon Has More Water and Ice Hidden All Over Its Surface Than Originally Predicted

Scientists discovered that water is stored in tiny patches all across the moon's surface, not just in the deep, freezing craters of its south pole

Future Moon Walkers Will Get 4G Cell Reception

NASA taps Nokia to install the first ever cellular network on the moon as part of a plan to establish long-term human presence on the lunar surface by 2030

The meteor shower is named for the Orion constellation because that’s where the meteors seem to emerge from.

How to See the Orionids Meteor Shower Peak Tonight

The meteor shower reaches peak visibility just before dawn on Wednesday morning but will last until November 7

This illustration depicts a star (in the foreground) experiencing spaghettification as it's sucked in by a supermassive black hole (in the background) during a 'tidal disruption event'.

Astronomers Capture Best View Yet of a Black Hole Spaghettifying a Star

The star was compressed and stretched out like a long noodle and when the ends collided, half of its mass ejected into space

Bennu is shaped like a three-dimensional diamond and seemingly smooth from far away. OSIRIS-REx is in the foreground of this artist’s replication. The spacecraft will gather a sample from Bennu next week.
