"This is the strongest accretion episode ever recorded for a planetary-mass object." Scientists have identified a lone planet with a ferocious appetite. Located in the Chamaeleon constellation roughly ...

Astronomers using the James Webb Space Telescope are unraveling the mysteries of TRAPPIST-1e, an Earth-sized exoplanet 40 light years away that could harbor liquid water. Early data suggests hints of ...

Astronomers have observed a massive growth rate in a free-floating rogue planet that’s gobbling up gas and dust at a record rate of 6.6 billion tons per second.

Astronomers using the Hubble Space Telescope have observed a white dwarf - a highly compact stellar ember - that appears to have gobbled up an icy world akin to the dwarf planet Pluto, a finding with ...

Hubble has captured a striking new image of NGC 2775, a galaxy that defies easy classification. Blending features of spirals, ellipticals, and lenticulars, its puzzling structure may be the result of ...

Astronomers have long sorted galaxies into types based on their visible structure. Spiral galaxies, like our Milky Way, have a flat disk, winding spiral arms and ongoing star formation. Ellipticals ...

This NASA/ESA Hubble Space Telescope image features a galaxy that's hard to categorize. The galaxy in question is NGC 2775, which lies 67 million light-years away in the constellation Cancer (the Crab ...

For researchers at the University of Idaho, spotting a moon 6 miles wide orbiting Uranus, a staggering 1.8 billion miles from Earth, may actually be easier than finding a white cat in a snowstorm.

The Habitable Worlds Observatory is poised to tell us whether Earth-like planets are common—if it can get off the ground ...

University of Warwick astronomers have uncovered the chemical fingerprint of a frozen, water-rich planetary fragment being consumed by a white dwarf star outside our solar system.

The James Webb Space Telescope has uncovered dazzling newborn stars and thick cosmic dust in Sagittarius B2, the Milky Way's most enormous star-forming cloud.
