Researchers have developed a new method to identify whether black hole mergers occurred inside dense clouds of dark matter, potentially opening a fresh...

New images from the NASA/ESA/CSA James Webb Space Telescope capture the barred spiral galaxy Messier 77 as a whirlpool of glowing dust, newborn stars and...

Space debris — ranging from defunct satellites and discarded rocket stages to fragments from collisions — poses an ever-increasing threat to...

In today’s Universe, most galaxies are held together by orderly rotation. But among the largest, no-longer star-forming systems, many are instead dominated...

A team of astronomers in Japan has detected a thin atmosphere around (612533) 2002 XV93, a trans-Neptunian object about 500 km in diameter — an object...

The existence of circumbinary planets — exoplanets that orbit binary stars — has only been firmly established over the past 15 years. Observations...

Using data from NASA’s Juno spacecraft, planetary scientists have produced the most precise measurements of Jupiter’s size in half a century and found...

Astronomers using the NASA/ESA Hubble Space Telescope have captured this vivid image of the spiral galaxy NGC 3137, which is located in the constellation...

New research by astronomers from the University of California, Riverside, Sam Houston State University and the University of Oklahoma suggests decaying...

An unusual object discovered by NASA’s Chandra X-ray Observatory may represent a missing link between hidden ‘black hole stars’ and fully exposed...

Water is made of two hydrogen atoms and one oxygen atom, hence its H2O formula. In typical water molecules, though, those hydrogen atoms have just one...

The Dark Energy Camera, a powerful 570-megapixel camera mounted on NSF’s Víctor M. Blanco 4-m telescope at Cerro Tololo Inter-American Observatory in...

Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected water-ice clouds swirling through the atmosphere of Epsilon Indi Ab, a cold...

A new anniversary image from the NASA/ESA Hubble Space Telescope reveals surprisingly fast evolution in a turbulent stellar nursery called the Trifid Nebula,...

New research by Professor Enrique Gaztañaga from the University of Portsmouth and the Institute of Space Sciences in Barcelona suggests some black holes...

Astronomers using the Dark Energy Spectroscopic Instrument (DESI) on NSF’s Nicholas U. Mayall 4-m telescope have produced the largest high-resolution...

The TOI-201 system consists of a super-Earth, a warm Jupiter, and a more massive brown dwarf at 5.8-, 53-, and 2,900-day orbital periods, respectively. An...

A new ‘agnostic biosignature’ method searches for patterns across exoplanets, suggesting alien life could be detected by how it spreads and reshapes...

Observations from the Subaru Telescope on January 7, 2026, revealed a surprisingly low carbon dioxide-to-water ratio, suggesting the composition of the...
