The highlight of the new chart is a wake of stars, stirred up by a small galaxy set to collide with the Milky Way. The map could also offer a new test of dark matter theories.

The milestone, which the MOXIE instrument achieved by converting carbon dioxide into oxygen, points the way to future human exploration of the Red Planet.

Scientists detect small pockets of carbon dioxide-rich liquid water in a meteorite dating from the early solar system.

Scientists have found fragments of titanium blasting out of a famous supernova. This discovery, made with NASA's Chandra X-ray Observatory, could be a major step in pinpointing exactly how some giant stars explode.

On May 1, 2019, researchers observed a record-setting flare from the star Proxima Centauri -- a burst of energy roughly 100 times more powerful than any similar event seen from Earth's sun.

Astronomers have discovered a pulsar -- a dense and rapidly spinning neutron star sending radio waves into the cosmos -- using a low-frequency radio telescope in outback Australia. The new pulsar is located more than 3,000 light-years from Earth and spins about once every second. Pulsars are used by astronomers for applications including testing the laws of physics under extreme conditions.
