Harvard University astronomers have proposed a new theory suggesting that the mysterious 'little red dots' first observed by the James Webb Space Telescope (JWST) two years ago represent new galaxies ...

Most stars in the Milky Way move at steady speeds, orbiting the galactic center in regular paths. But astronomers have ...

Searching for exoplanets within these disks is highly challenging. Astronomers use clues from the shape and morphology of the disks to infer the presence of exoplanets. Fomalhaut's debris disk ...

T he nearby (on a galactic scale) star Fomalhaut has a giant ring that has puzzled astronomers since its discovery in 2005.

Concept design for a rectangular space telescope, modeled after the Diffractive Interfero Coronagraph Exoplanet Resolver (DICER), a notional infrared space observatory, and the James Webb Space ...

The Earth supports the only known life in the universe, all of it depending heavily on the presence of liquid water to facilitate chemical reactions. While single-celled life has existed almost as ...

Scientists from a San Antonio-based research hub have found a new moon orbiting Uranus using NASA’s James Webb Space Telescope. Southwest Research Institute said it discovered a previously unknown ...

Called 3I/ATLAS, the object is only the third of its kind known to astronomers, and it’s likely been heading our way for ...

Transmissions between Earth and our own spacecraft could tell us where to look for potential alien transmissions.

However, subsequent data from the Hubble Space Telescope suggested that 3I/ATLAS is probably closer to a maximum of 3.5 miles (5.6 km) across. Either way, it's likely the largest interstellar object ...

Astronomers using the NASA/ESA Hubble Space Telescope have produced a spectacularly detailed image of the asymmetric spiral galaxy Messier 96. Messier 96 is a spiral galaxy located in the ...

Hubble reveals white dwarf WD 0525+526 with unusual carbon levels Star likely formed from stellar merger, not standard stellar death Discovery may reshape theories on white dwarfs and supernova ...
