Peering deep into 'The Brick,' a dark, chaotic gas cloud at the heart of the Milky Way, the James Webb Space Telescope uncovered secrets that could shake up theories of star formation.

While hunting for dark matter, astronomers accidentally discovered the first known stellar stream stretching between galaxies. The trail of stars is also the longest ever seen.

NASA and scientists from around the world are sending new science instruments, as well as a few stocking stuffers, to the moon on Dec. 24 in the debut launch of a new rocket.

Betelgeuse, the most famous red supergiant star and one of the sky's brightest, will disappear for up to 12 seconds during an ultra-rare occultation by asteroid 319 Leona.

The James Webb Space Telescope's discovery of water and other molecules in the inner region of a hot protoplanetary disk suggests that rocky, Earth-like planets may be able to form in some very extreme environments.

Shortly after lifting off from Florida, a SpaceX Falcon 9 rocket flew through clouds of ice crystals, temporarily creating a bright halo of light that appeared to surround the full moon.

A monstrous dark patch, known as a coronal hole, recently appeared near the sun's equator. The temporary gap enables unusually fast solar wind to race toward Earth.

Located about 2.5 million light-years from our solar system, Andromeda is the most distant object visible to the naked eye.

Salty glaciers discovered in craters near Mercury's north pole may have the right conditions for extreme forms of life, new research suggests.

A distant comet trapped in orbit between Saturn and Uranus is accompanied by a transforming disk of icy dust, new observations reveal.
