Streams of star-forming gas dripping from the disk of a spiral galaxy called JW100 are formed by a process called ram pressure stripping, and their resemblance...
The new animation shows the gamma-ray sky’s frenzied activity during a year of observations by the Large Area Telescope (LAT) aboard NASA’s Fermi Gamma-ray...
Planetary scientists have examined volcanic areas on Venus that were imaged two or three times by NASA’s Magellan spacecraft and identified a 2.2-km2...
Wolf-Rayet stars are in the process of casting off their outer layers, resulting in their characteristic halos of gas and dust. The new Webb images of...
The subsurface ocean of Jupiter’s icy moon Europa is heated from below via tidal heating and radioactive decay of the rocky interior, while being cooled...
Astronomers from the COSMOS-Web program released mosaic images taken in early January 2023 by the Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument...
NASA has released a stunning photo taken by the NASA/ESA Hubble Space Telescope of the dwarf galaxy UGCA 307.

3C 297 is located about 9.2 billion light-years away in the constellation of Virgo and contains a quasar, a supermassive black hole pulling in gas at the...
In the lower atmosphere of Earth, oxygen contains a higher fraction of the heavy isotope 18O than ocean water does. This enrichment is a signature of biological...
‘Sun rays’ are also known as crepuscular rays, from the Latin word for twilight. It was the first time sun rays have been so clearly viewed on Mars.
