The Magnetic Superhighways That Drive Galaxy Evolution February 2, 2026
Arp 220 is a well-known pair of galaxies that are merging. New ALMA observations of polarized light reveal the complex and powerful magnetic fields that shape the process.
Hubble And The Fingerprints Of An Ancient Merger February 2, 2026
This NASA/ESA Hubble Space Telescope image shows NGC 7722, a lenticular galaxy about 187 million light-years away in the constellation Pegasus. This “lens-shaped” galaxy sits in between more familiar spiral alaxies and elliptical galaxies in the galaxy classification scheme. The dark, dramatic dust lanes are the fingerprints of an ancient galaxy merger.
For the First Time, Scientists Detect Molecule Critical to Life in Interstellar Space January 31, 2026
For the first time, a complex, ring-shaped molecule containing 13 atoms—including sulfur—has been detected in interstellar space, based on laboratory measurements. The discovery closes a critical gap by linking simple chemistry in space with the complex organic building blocks found in comets and meteorites. This represents a major step toward explaining the cosmic origins of […]
Cracks on Europa Sport Traces of Ammonia January 31, 2026
The search for life-supporting worlds in the Solar System includes the Jovian moon Europa. Yes, it's an iceberg of a world, but underneath its frozen exterior lies a deep, salty ocean and a nickel-iron core. It's heated by tidal flexing, and that puts pressure on the interior ocean, sending water and salts to the surface. […]
"Red Geyser" Galaxies Have Plenty of Star-Forming Gas But Don't Form Stars January 30, 2026
Red Geysers are an unusual class of galaxy that contain only old stars. Despite having plenty of star-forming gas, Red Geysers are quenched. Astronomers have mapped the flow of gas in these galaxies and figure out why they're dormant.
