A 'super-puff' exoplanet is losing its atmosphere, and the James Webb Space Telescope had a look

By Samantha Mathewson published

Astronomers have spotted a distant world "shedding" its atmosphere into space in real time, creating a giant cloud of helium gas that sweeps across its parent star well before the planet itself.

James Webb Space Telescope captures 'one-of-a-kind' triple star system that looks like a cosmic embryo (image)

By Keith Cooper published

The unique system features two rare Wolf-Rayet stars, and a supergiant companion that is interrupting the flow of the dust shells that the two Wolf-Rayet stars cast off.

How AI fixed the James Webb Space Telescope's blurry vision

By Tereza Pultarova published

An ultra-high-resolution instrument on board NASA's $10 billion James Webb Space Telescope has been suffering from blurry vision. AI helped fix the problem.

A large planetary nebula. The nebula’s central star is hidden by a blotchy pinkish cloud of dust. A strong red light radiates from this area, illuminating the nearby dust. Two large loops extend diagonally away from the centre, formed of thin ridges of molecular gas, here coloured blue. They stretch out to the corners of the view. A huge number of bright, whitish stars cover the background, also easily visible through the thin dust layers.

A composite view of spiral galaxy NGC 1637 from the JWST and Hubble telescopes reveals the site of the progenitor star that became SN 2025pht. Insets show a red supergiant star that was invisible to Hubble before its explosion but detected by JWST; Hubble’s July 2025 image captures the brilliant aftermath of the supernova.

JWST spots dust-cloaked 'red supergiant' star just before it went supernova

By Sharmila Kuthunur published

Astronomers using JWST have captured the clearest view yet of a doomed red supergiant star just before it exploded, solving a decades-old mystery about why such stars rarely appear to go supernova.
