Using the Subaru Telescope and the Keck II telescope at the W. M. Keck Observatory, astronomers have discovered and directly imaged a brown dwarf orbiting...
Astronomers using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered two exoplanets transiting inactive red dwarf stars TOI-122...
In a new study published in the Astrophysical Journal Letters, astronomers investigated the effects the activity of the red dwarf star Proxima Centauri...
‘Superbolts’ are distinct from typical lightning flashes and can be more than 1,000 times brighter, according to two new papers published in the Journal...
Mars was once a wet planet, but it has lost most of its water through reactions that produce hydrogen. In standard models, molecular hydrogen produced...
Water may emerge in connection with the formation of terrestrial planets, according to a new analysis of a Martian meteorite called North West Africa (NWA)...
Using computer simulations, an international team of astronomers has studied the weather conditions on K2-141b, an Earth-size exoplanet with supersonic...
Barnard’s star, a 10-billion-year-old red dwarf just 6 light-years from Earth, is still very active and potentially destructive for the atmospheres of...
NASA’s Juno spacecraft has been in orbit around Jupiter since 2016. One of its instruments is the ultraviolet spectrograph (UVS), which is primarily...
Using high sensitivity spectroscopic observations from the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected a small cyclic...
Using data collected by the InfraRed Array Camera aboard NASA’s Spitzer Space Telescope and NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have spotted airborne plumes of sulfur dioxide (SO2), sulfur monoxide (SO), and...
The Antarctica’s ozone hole has now reached its maximum size, according to an analysis of data collected by ESA’s Copernicus Sentinel-5P satellite.
This...
The end-Permian mass extinction, also known as the Permian-Triassic extinction event and the Great Dying, is the largest mass extinction event in Earth’s...
Solar storms strip a planet’s atmosphere over time, and only a strong magnetosphere would be able to provide maximum protection. Lunar samples gathered...
The bright frosts observed in 2015 in the equatorial region of Cthulhu on Pluto are mostly made of methane-rich ice, according to new research.
This image,...
Astronomers using the HARPS (High Accuracy Radial velocity Planet Searcher) spectrograph at ESO’s La Silla Observatory in Chile have detected gaseous...
If the atmosphere of Venus was at any point thin and similar to Earth’s, then ancient asteroid impacts transferred potentially detectable amounts of...
Astronomers have discovered an ultra-short-period Neptune-sized exoplanet orbiting the bright Sun-like star LTT 9779.
An artist’s impression of the ultrahot...
Early in the formation of Jupiter as a planet, it moved closer to and then away from the Sun due to interactions with the planetary disk of the young Solar...
