Using the James Webb Space Telescope (JWST), astronomers have performed near-infrared observations of a dwarf galaxy known as Ark 227. The observational campaign led to the serendipitous discovery of an extended stellar halo ...
Using NASA's Spitzer and WISE space telescopes, astronomers from the Steward Observatory and elsewhere have observed a well-known variable star designated RZ Piscium. They found that the star's circumstellar debris disk is ...
By analyzing deep optical imagery from the IAC Stripe 82 Legacy Project, an international team of astronomers has serendipitously discovered a new almost dark galaxy. The newfound galaxy, dubbed "Nube," has a very low surface ...
Cataclysmic events happen in the universe all the time. Black hole mergers, supernovae, gamma-ray bursts, and a whole host of others. Most of them happen in distant galaxies, so they pose no threat to us. But there are a ...
