Beautifully captured by the James Webb Space Telescope (JWST), this image shows interstellar gas and dust lit up by a dead star in Cassiopeia.

In 1181, a new star shone near the Cassiopeia constellation for six months ... Now known as the supernova SN 1181, its ...

NASA’s James Webb Space Telescope’s new view of Cassiopeia A (Cas A) in near-infrared light is giving astronomers hints at the dynamical processes occurring within the supernova remnant.

NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) detected the magnetic field streamlines shown over this image of the Keyhole Nebula, part of the larger Carina Nebula, captued by the ...

Water may have formed less than 200 million years after the Big Bang, suggesting some conditions for life existed far earlier than previously thought.

The NIRCam image displayed the inner shell of Cas A in hues, representing gas knots rich in elements like sulfur, oxygen, argon, and neon Contributions to new stars and planetary systems Debris ...

India's X-ray Polarimeter Satellite (XPoSat) achieved a significant milestone by capturing its first light from the Cassiopeia A (Cas A) supernova remnant, marking a crucial step in its mission ...
