One of the ways massive stars, those at least 10-times bigger than the Sun, reach their end is in a supernova—an enormous explosion caused by the star’s core running out of fuel. One consequence of a ...

This image of galaxy GS-NDG-9422, captured by the James Webb Space Telescope's NIRCam (Near-Infrared Camera) instrument, is presented with compass arrows, scale bar, and colour key for reference.

A nearby active galaxy called VV 340a offers a dramatic look at how a supermassive black hole can reshape its entire host. Astronomers observed a relatively weak but restless jet blasting outward from ...

This AI component allowed the researchers to capture the galaxy's overall behavior while still modeling small-scale events, including the fine details of individual supernovae. The team validated the ...

New telescope instruments are pushing galaxy observation far beyond what was possible a decade ago. Advances in space telescope technology now allow astronomers to study billions of galaxies across ...
