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...
Astronomers have discovered a super-Earth exoplanet orbiting a dwarf star or a brown dwarf around 7,580 parsecs (24,723 light-years) from Earth.
An artist’s...
Astronomers using the Fiber-fed Extended Range Optical Spectrograph (FEROS) on the MPG/ESO 2.2-m telescope at ESO’s La Silla Observatory have found a...
A team of astrobiologists from the Carl Sagan Institute at Cornell University has developed a spectral field guide for Earth-like exoplanets transiting...
Magnetic activity on the Sun leads to solar flares, coronal mass ejections, and other space weather that affects Earth. Similar activity on other stars...
Astronomers using the PIONIER (Precision Integrated-Optics Near-infrared Imaging ExpeRiment) instrument on ESO’s Very Large Telescope Interferometer...
Professor Andrew King from the University of Leicester has shown that periodic X-ray eruptions from a galaxy called GSN 069 could result from the core...
In celebration of the 30th anniversary of the launch of the NASA/ESA Hubble Space Telescope, astronomers used the telescope to take a portrait of the giant...
Comets spend most of their lives at large distances from any star, during which time their interior compositions remain relatively unaltered. Cometary...
Clusters of supernovas can cause the birth of scattered, eccentrically orbiting stars in outer halos of Milky Way-mass galaxies, according to new research...
