NASA’s Webb Studies How Planet Survived Death of its Star

NASA’s James Webb Space Telescope is giving us new insight into the far-future of solar systems like our own, as the agency continues to reveal the secrets of the universe and our place in it. Billions of years ago, a Sun-like star nearing the end of its life swelled tremendously in size to become a […]

NASA’s Hubble Sees White Dwarf Eating Piece of Pluto-Like Object

In our nearby stellar neighborhood, a burned-out star is snacking on a fragment of a Pluto-like object. With its unique ultraviolet capability, only NASA’s Hubble Space Telescope could identify that this meal is taking place. The stellar remnant is a white dwarf about half the mass of our Sun, but that is densely packed into […]

X-ray Signal Points to Destroyed Planet, Chandra Finds

A planet may have been destroyed by a white dwarf at the center of a planetary nebula — the first time this has been seen. As described in our latest press release, this would explain a mysterious X-ray signal that astronomers have detected from the Helix Nebula for over 40 years. The Helix is a […]
