This is the “Exposed Cranium” nebula, also known as Nebula PMR 1. Located some 5,000 light-years away in the constellation Vela, it’s a massive, moribund star coming to the end of its fuel-burning ...

Although astronomers have found thousands of exoplanets, the number of confirmed exomoons—and exorings—is still zero. But ...

New research using NASA’s James Webb Space Telescope examines the maximum sizes of gas giant exoplanets, measuring chemical compositions and formation processes in the HR 8799 system.

"The most likely explanation for the dimming is a brown dwarf – an object heavier than a planet but lighter than a star – surrounded by a vast and dense ring system." When you purchase through links ...

One way gas giants form is through core accretion, where solid cores gradually grow in a disk by pulling in rocky and icy pebbles until they become massive enough to attract the gas that surrounds ...

An artist’s impression of the stellar dimming event caused by a brown dwarf or super-Jupiter with massive rings (foreground) forming an opaque “saucer” through which some light from the star ...

Using the James Webb Space Telescope (JWST), astronomers have discovered a new dwarf galaxy, which received designation CAPERS-39810. Further investigation of CAPERS-39810 revealed that it is an ...

James Webb Space Telescope (JWST) has captured the most intricate view yet of the Helix Nebula, offering a sharp, infrared glimpse into the final moments of a dying sun. Affectionately nicknamed ...

Astronomers on Mauna Kea found the first space object on which NASA’s Roman Space Telescope can test its imaging technology. A new “massive planet” also was found, the W.M. Keck Observatory said in a ...

An artistic rendering of a dust and gas disk encircling the young exoplanet, CT Cha b, 625 light-years from Earth. Spectroscopic data from NASA’s JWST suggest the disk contains the raw materials for ...
