As we head toward summer, JWST is getting ready to start its second year of science operations. During its brief period of operations, this $8.8 billion spacecraft has been working hard to prove it can do science worthy of its price tag. Adding to it’s list of...

Part of the simulated universe. Credit: The AGORA Collaboration In a paper that made me do math, researchers have shared the results of a remarkable new suite of simulations that explore how galaxies are born, live, and evolve. Over 160 researchers from 60...

False-colour JWST image of a small fraction of the GOODS South field, with JADES-GS-z7-01-QU highlighted. Credit: JADES Collaboration In a paper in Nature, with Tobias Looser as the first author, researchers discuss a galaxy cataloged as JADES-GS-z7-01-QU. This...

This image from Webb’s NIRCam (Near-Infrared Camera) instrument shows a portion of the GOODS-North field of galaxies. At the lower right, a pullout highlights the galaxy GN-z11, which is seen at a time just 430 million years after the Big Bang. One prominent...

This illustration provided by the European Southern Observatory in February 2024, depicts the record-breaking quasar J059-4351, the bright core of a distant galaxy that is powered by a supermassive black hole. The supermassive black hole, seen here pulling in...
