This supernova, detected as part of the JWST Advanced Deep Extragalactic Survey (JADES ... Current estimates suggest Roman's wide field of view will locate thousands of early supernovas for ...

A team of astronomers sifted through James Webb Space Telescope data from multiple surveys to compile one of the largest ...

On April 6, 2024, the JWST detected a 40-minute flare from the black hole. The telescope's observations backed up the simulations that suggest criss-crossing magnetic field lines drive the flares. The ...

Since its launch on Christmas Day, 2021, the James Webb Space Telescope has proven its worth year after year. 2024 is no exception. Here are just five times the ultrapowerful telescope has ...

Using massive clusters of galaxies as gigantic magnifying glasses, JWST’s sensitive cameras can also peer deep into the cosmos to find the faintest galaxies. We pushed further to find the point ...
