The James Webb Space Telescope (JWST) has detected a possible supernova in the early universe just days after the star exploded. Called AT 2026abck, the transient lies in a star-forming galaxy at a ...

When a star reaches its final stages of life, it ends in a bright and powerful explosion called a supernova and scatters material across the universe. A new study led by a University of Hawaiʻi at ...

Hubble observations connect galactic winds and reionization, finding that stronger outflows in six compact galaxies accompany less escaping ionizing radiation.

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets ...

Earth is quietly collecting radioactive debris from an ancient stellar explosion as our Solar System drifts through a giant cloud of gas and dust between the stars. Scientists analyzing Antarctic ice ...
