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...
Because of its proximity to its parent star, the dayside equilibrium temperature of the ultrahot Jupiter WASP-189b reaches 3,162 degrees Celsius (5,724...
Two new photos, taken with the NASA/ESA Hubble Space Telescope, show Jupiter with its turbulent atmosphere and giant storms. One of the images also features...
Astronomers using the James Clerk Maxwell Telescope (JCMT) and the Atacama Large Millimeter/submillimeter Array (ALMA) have detected phosphine (PH3) gas...
Using NASA’s Transiting Exoplanet Survey Satellite (TESS) and two ground-based instruments, astronomers have discovered and confirmed a transiting hot...
The red supergiant Betelgeuse is one of the brightest stars in the night sky and appears even more luminous because it is so close to Earth, only 650 light-years...
Using new data from the Imaging Ultraviolet Spectrograph (IUVS) on NASA’s MAVEN (Mars Atmosphere and Volatile Evolution) spacecraft, scientists have...
A new study suggests that during Jupiter’s violent storms, hailstones form from a cooled mixture of water and ammonia gas, similar to the process in...
Taking advantage of a total lunar eclipse in January 2019, astronomers using the NASA/ESA Hubble Space Telescope have measured the amount of ozone in the...
The Visual Monitoring Camera (VMC) on ESA’s Mars Express spacecraft has captured new images of a giant cloud over the 20-km (12.4-mile) high Arsia Mons...
The Atmospheric Chemistry Suite (ACS) aboard ESA’s ExoMars Trace Gas Orbiter (TGO) has spotted never-before-seen spectral signatures of ozone and carbon...
