Using the James Webb Space Telescope (JWST), astronomers obtained high-contrast coronagraphic images of the protoplanetary disk around the young, nearby star TW Hydrae. Results of the observational campaign, published July ...
Using spectral data from the Dark Energy Spectroscopic Instrument (DESI), astronomers have gained some of the clearest evidence yet that white dwarf stars are accreting debris from disintegrating exoplanets. Captured while ...
