Webb Zooms into Helix Nebula

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 […]

NASA Telescopes Spot Surprisingly Mature Cluster in Early Universe

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 Webb Pushes Boundaries of Observable Universe Closer to Big Bang

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 […]
