This discovery is out of this world. For the first time since its operations began in 2021, the James Webb Space Telescope (JWST) has captured a direct image, published by the journal Nature, of a new ...

Star formation begins with protostars in cold molecular clouds, where gravitational contraction precedes nuclear fusion, and their early evolutionary stages are best characterized through ...

The James Webb Space Telescope has taken its first look at black holes secretly snacking on stars within dusty galaxies. JWST’s ability to pick up detailed infrared signals lets it peer past the dust ...

In this image, light from the star TWA 7 has been subtracted. The potential exoplanet TWA 7 b is the orange circle within the blue debris disk. NASA, ESA, CSA, Anne-Marie Lagrange (CNRS, UGA), Mahdi ...

The supermassive black hole is that first one that astronomers ever photographed. For more than a century, astronomers have marveled at the brilliant jet of matter blasting from the heart of the giant ...

Jupiter's moon Io stands alone among the solar system's moons. It has more than 400 active volcanoes, and its surface is home to more than 100 massive volcanic mountains, some of which are taller than ...

New observations from the James Webb Space Telescope hint that the universe’s first stars might not have been ordinary fusion-powered suns, but enormous “supermassive dark stars” powered by dark ...

For decades, astronomers have searched the skies for a missing population of doomed stars — the massive red supergiants that theory predicts should end their lives in powerful stellar explosions, but ...
