Inspired by the half-human, half-horse creatures that are part of Ancient Greek mythology, the field of astronomy has its own kind of centaurs: distant objects orbiting the sun between Jupiter and Neptune. NASA’s James Webb Space Telescope has mapped the gases spewing from one of these objects, suggesting a varied composition and providing new insights into the formation and evolution of the solar system.

Centaurs are former trans-Neptunian objects that have been moved inside Neptune’s orbit by subtle gravitational influences of the planets in the last few million years, and may eventually become short-period comets...

Researchers have discovered the most distant active supermassive black hole to date with the James Webb Space Telescope (JWST). The galaxy, CEERS 1019, existed about 570 million years after the big bang, and its black hole is less massive than any other yet identified in the early universe.

In addition to the black hole in CEERS 1019, the researchers identified two more black holes that are on the smaller side and existed 1 billion and 1.1 billion years after the big bang...

Two Southwest Research Institute scientists were part of a James Webb Space Telescope (JWST) team that observed a towering plume of water vapor more than 6,000 miles long—roughly the distance from the U.S. to Japan—spewing from the surface of Saturn’s moon, Enceladus...

To gaze at the stars is human. To be able to see them in 3D detail is very nearly divine.
Divine vision is what the James Webb Space Telescope has granted Earthbound scientists in a new near-infrared, detailed image of Cassiopeia A (Cas A), a stellar remnant—the clouds of gas, dust and other material left behind when a star dies. Danny Milisavljevic, assistant professor of physics and astronomy in Purdue University’s College of Science, studies supernova remnants and leads a year one research team on the JWST examining Cas A.

“I have spent 17 years studying stars and their ...
