NASA’s Chandra Finds Young Stars Dim Quickly

These images, released on April 14, 2026, show two open star clusters, Trumpler 3 (left) and NGC 2353 (right). They represent a recent study from NASA’s Chandra X-ray Observatory that shows how young Sun-like stars are dimmer in X-rays than previously thought. This latest study looked at eight clusters of stars between the ages of […]

NASA’s Hubble and Webb Telescopes Reveal Two Faces of a Star Cluster Duo

A riotous expanse of gas, dust, and stars stake out the dazzling territory of a duo of star clusters in this combined image from NASA’s Hubble and Webb space telescopes. Open clusters NGC 460 and NGC 456 reside in the Small Magellanic Cloud, a dwarf galaxy orbiting the Milky Way. Open clusters consist of anywhere […]
