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...
Giant elliptical galaxies are not as likely as previously thought to be cradles of complex life, according to a paper published in the Monthly Notices...
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...
Using the High-Resolution Echelle Spectrometer (HIRES) instrument on the 10-m Keck I telescope at W.M. Keck Observatory, astronomers have discovered a...
At least 17 high-inclination Centaurs and two trans-Neptunian objects were captured by the Solar System from the interstellar medium, according to a new...
Clusters of supernovas can cause the birth of scattered, eccentrically orbiting stars in outer halos of Milky Way-mass galaxies, according to new research...
At the center of the Milky Way lurks Sagittarius A*, a supermassive black hole that is four million times the mass of the Sun. Located 26,000 light-years...
Astronomers using data from NASA’s Kepler Space Telescope have discovered an Earth-sized planet in the habitable zone of a low-mass star called Kepler-1649.

A nova is a sudden, short-lived brightening of an otherwise inconspicuous star. It occurs when a stream of hydrogen from a companion star flows onto the...
A due of researchers used numerical simulations to show that interstellar objects like ‘Oumuamua, a fast moving, cigar-shaped object of extrasolar origin...
Brown dwarfs are cool, dim objects that have a size between that of a gas giant, such as Jupiter or Saturn, and that of a Sun-like star. Sometimes called...
In a new study published in the journal Nature Astronomy, a team of planetary researchers from the United States and France studied the photochemical role...
Astronomers using the CARMENES spectrograph at Calar Alto Observatory in Spain have discovered a super-Earth exoplanet orbiting an M-dwarf star in the...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have spotted an Earth-sized planet orbiting LHS 1815, a star in the thick disk...
A research team led by Harvard University scientist Julie McGeoch has found a never-before-seen protein inside a meteorite called Acfer 086.
A sample of...
