This shimmering region of star-formation, a close-up of the Trifid Nebula about 5,000 light-years from Earth, was captured in intricate detail by NASA's Hubble Space Telescope. The colors in Hubble's visible light image, ...
Astronomers using the W. M. Keck Observatory on Maunakea, Hawaiʻi Island are revealing new insight into the composition and origins of Uranus's two outer rings. Using data from the Keck Observatory Archive (KOA), combined ...
For the last five years, the Dark Energy Spectroscopic Instrument (DESI) has been systematically scanning the night sky. Today marks the completion of its first map, which is the largest high-resolution 3D map of the universe ...
At this point in NASA's human spaceflight story, researchers have a substantial amount of material—documents, artifacts and images—with which to tell the stories of past flights to space. But with NASA's Artemis II mission ...
This month's NASA/ESA/CSA James Webb Space Telescope Picture of the Month offers us a two-for-one on brand new stars—with some potential planets thrown in as well. This visual highlights Webb's views of the protoplanetary ...
New research suggests that neutrinos in the early universe may have transformed into a previously unknown form of radiation. A study from Washington University in St. Louis offers a new way to explain certain puzzling observations ...
Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense gravitational pull, the rotational spins of galaxies would force them to simply fly apart. But now, ...
Drawing together leading experts from across the field, an international collaboration of cosmologists has created a unified approach for measuring the value of the Hubble constant. Published in Astronomy & Astrophysics, ...
Douglas Adams told us the answer to life, the universe and everything is 42. If only cosmology were so straightforward. Astronomers have been arguing for years about a number every bit as fundamental, and they still can't ...
A luminous swirl set against the deep black of space, the barred spiral galaxy IC 486 glows with a soft, ethereal light in this new NASA/ESA Hubble Space Telescope Picture of the Month image. IC 486 lies right on the edge ...
