Astronomers with the help of the James Webb Space Telescope have detected radiation from a brown dwarf star, suggesting it may produce auroras like those seen near Earth’s poles and …
NASA’s James Webb Space Telescope is asking big questions about the early universe. In its first images, JWST captured seemingly massive galaxies in the ancient universe. In fact, these galaxies …
Researchers may have solved the mystery of why a distant galaxy surrounded by an unusually perfect “Einstein ring” is denser than it should be: The giant galaxy has been discovered …
Space is very psychedelic. There are objects in the universe that are so massive—usually clusters of galaxies—that they warp space like a bowling ball on a mattress. This creates a …

two supernovaes In a galaxy, and so far away that we see it as it did 10 billion years ago, it could be crucial in helping to reveal how fast …
Huge clusters of galaxies distort space-time to the point where they act like lenses. The light from more distant galaxies is distorted and amplified, giving astronomers the chance to see …
NASA’s James Webb Space Telescope discovered a multiple-image supernova named MRG-M0138 in a distant galaxy. Two supernova images (circled) are visible in the Webb NIRCam (Near Infrared Camera) image above, …
