Observations made with NASA’s newly refurbished Hubble Space Telescope of a nearby supernova are allowing astronomers to measure the velocity and composition of “star guts” being ejected into space ...

An exploding star, in nearby galaxy M51, shows signs of an unusual composition. The material thrown into space in the explosion contains a wide variety of elements -- a mix that is atypical of ...

The cosmic record breaker has now been confirmed by astronomers, who see that the James Webb Space Telescope has detected ...

This image by NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) shows different structural details of the Crab Nebula. The supernova remnant is ...

In an exciting new study published in Nature Astronomy, astronomers have unveiled unexpected findings from the XRISM satellite mission. The research team, led by experts from Japan and the U.S., ...

When a dense stellar core called a white dwarf acquires enough material from a companion star orbiting nearby, it burns up in the nuclear fusion blast of a Type Ia supernova. This ejects freshly ...

Around July 4, 1054, Chinese astronomers recorded a “guest star” that shone so brightly, it was visible in broad daylight for 23 days. The remnants of that long-ago supernova now form the Crab Nebula, ...
