Webb looks for Fomalhaut's asteroid belt and finds much more

Astronomers used NASA's James Webb Space Telescope to image the warm dust around a nearby young star, Fomalhaut, in order to study the first asteroid belt ever seen outside of our solar system in infrared light. But to their ...

NASA's retired Compton mission reveals superheavy neutron stars

Astronomers studying archival observations of powerful explosions called short gamma-ray bursts (GRBs) have detected light patterns indicating the brief existence of a superheavy neutron star shortly before it collapsed into ...

Hubble captures rare 'light echo' from star explosion

When a star explodes (a supernova), it sends its intense burst of light out in all directions. On rare occasions, in the months and years that follow, rings of light or "light echoes" spread out from the original supernova ...

Astronomers capture surprising changes in Neptune's temperatures

An international team of astronomers have used ground-based telescopes, including the European Southern Observatory's Very Large Telescope (ESO's VLT), to track Neptune's atmospheric temperatures over a 17-year period. They ...

Views of comet Leonard from two sun-watching spacecraft

When Comet Leonard, a mass of space dust, rock and ice about a half-mile (1 kilometer) wide, makes its closest pass of the Sun on Jan. 3, 2022, it will be a journey 40,000 years in the making. Ahead of its close pass, two ...
