An international team of astronomers has used the James Webb Space Telescope (JWST) to observe the planetary nebula NGC 6720, better known as the Ring Nebula. The observational campaign, described in a paper on the pre-print ...
An international team of astronomers has detected four new "hot Jupiter" exoplanets as part of the Next Generation Transit Survey (NGTS). The newly found alien worlds are at least 10% larger than Jupiter but less massive ...
Exoplanet surveys have yielded many surprises over the years, and the discovery of "disintegrating" exoplanets was one of them. These are planets that produce asymmetric shapes in the dips of the light curves seen as they ...

Using ESA's XMM-Newton space telescope, astronomers have found that the planetary nebula NGC 5189 harbors a carbon-enriched X-ray-emitting hot bubble. The discovery, presented in a paper published September 30 on arXiv.org, ...
Four years ago, several red giant stars were discovered to pose a paradox: even though they are built from very old stellar material, their large masses indicate a clearly younger age. Scientists from the Max Planck Institute ...

An international team of astronomers has detected a new brown dwarf with an ultra-short orbital period that transits an active M-dwarf star. The newfound object, designated NGTS-7Ab, turns out to be the shortest period transiting ...
Planets orbiting binary stars are in a tough situation: They have to contend with the gravitational pull of two separate stars. Planetary formation around a single star like our sun is relatively straightforward compared ...
