Astronomers have discovered and validated two small exoplanets orbiting the nearby red dwarf star TOI-1266. An artist’s impression of the TOI-1266 planetary...

Using NASA’s Neil Gehrels Swift Observatory, ESA’s XMM-Newton observatory, NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), and ground-based...

Using data from NASA’s Kepler/K2 mission, the SPECULOOS telescopes and the High Resolution Echelle Spectrometer (HIRES) on the Keck I telescope at W.M....

New estimate suggests that 18% of Sun-like (G-type) stars could have a planet the size of Earth orbiting in their conservative habitable zone. There may...

Astronomers have finally confirmed the existence of two exoplanets — Proxima b and c — orbiting Proxima Centauri, the Sun’s closest stellar...

Astronomers have long used a so-called parallax effect — how a star appears to shift against its background when seen from different locations —...

Peter Pan disks are a recently-discovered class of long-lived protoplanetary disks around low-mass stars that survive 5-10 times longer than typical protoplanetary...

Astronomers using data from NASA’s Kepler space telescope have discovered two new planets in the Kepler-160 planetary system. One of the new planets...

Astronomers using the NASA/ESA Hubble Space Telescope have found no evidence of hypothetical first-generation stars — called Population III stars...

Massive neutron stars have sizable quark-matter cores, according to a study published in the journal Nature Physics. An artist’s conception of a massive...

Astronomers using NASA’s Chandra X-ray Observatory have observed a pair of relativistic jets blasting away from a black hole in the binary system MAXI...

Using several instruments on ESO’s Very Large Telescope, VLT Survey Telescope and the New Technology Telescope, astronomers have discovered giant spots...

NASA has released a beautiful new image taken by the Hubble Space Telescope of NGC 6441, one of about 150 globular clusters belonging to our Milky Way...

Astronomers using the NASA/ESA Hubble Space Telescope have observed young stars in a crowded stellar cluster called Westerlund 2. They’ve found that...

Fast blue optical transients (FBOTs) share some characteristics with supernova explosions of massive stars and with explosions that generate gamma-ray...

Using three instruments on ESO’s Very Large Telescope (VLT), an international team of astronomers has discovered and imaged a giant sub-stellar object...

Astronomers using the SPHERE (Spectro-Polarimetric High-contrast Exoplanet Research) instrument on ESO’s Very Large Telescope (VLT) have observed a protoplanetary...

Using the Near-Infrared Camera (NIRC2) on the Keck II telescope at W. M. Keck Observatory on Maunakea in Hawaii, astronomers have directly imaged two infant...

An international team of astronomers has discovered a close-in super-Earth exoplanet in the HD 164922 planetary system. An artist’s impression of the...

Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have detected pulsation patterns in the so-called Delta Scuti stars, a large group...
