A new discovery captures the cosmic moment when a galaxy cluster – among the largest structures in the universe – started to assemble only about a billion years after the big bang, one or two billion years earlier than previously thought. This result, made using NASA’s Chandra X-ray Observatory and James Webb Space Telescope, will […]

NASA’s James Webb Space Telescope has topped itself once again, delivering on its promise to push the boundaries of the observable universe closer to cosmic dawn with the confirmation of a bright galaxy that existed 280 million years after the big bang. By now Webb has established that it will eventually surpass virtually every benchmark […]

The Discovery A candidate planet that might be remarkably similar to Earth, HD 137010 b, has one potentially big difference: It could be colder than perpetually frozen Mars. Key Facts Scientists continue to mine data gathered by NASA’s Kepler Space Telescope, retired in 2018, and continue to turn up surprises. A new paper reveals the […]

A team of astronomers has employed a cutting-edge, artificial intelligence-assisted technique to uncover rare astronomical phenomena within archived data from NASA’s Hubble Space Telescope. The team analyzed nearly 100 million image cutouts from the Hubble Legacy Archive, each measuring just a few dozen pixels (7 to 8 arcseconds) on a side.

At the heart of our own galaxy, there is a dense thicket of stars with a supermassive black hole at the very center. NASA’s Nancy Grace Roman Space Telescope will provide the deepest-ever view of this zone, revealing stars, planets, and unique objects that resist definition. Based on the input of astronomers from across the […]

Astronomers have long sought evidence to explain why comets at the outskirts of our own solar system contain crystalline silicates, since crystals require intense heat to form and these “dirty snowballs” spend most of their time in the ultracold Kuiper Belt and Oort Cloud. Now, looking outside our solar system, NASA’s James Webb Space Telescope […]

NASA’s James Webb Space Telescope has zoomed into the Helix Nebula to give an up-close view of the possible eventual fate of our own Sun and planetary system. In Webb’s high-resolution look, the structure of the gas being shed off by a dying star comes into full focus. The image reveals how stars recycle their […]

Newly developing stars shrouded in thick dust get their first baby pictures in these images from NASA’s Hubble Space Telescope. Hubble took these infant star snapshots in an effort to learn how massive stars form. Protostars are shrouded in thick dust that blocks light, but Hubble can detect the near-infrared emission that shines through holes […]
