Using ultraviolet data from the NASA/ESA Hubble Space Telescope, astronomers have detected carbon ions — charged particles that interact with magnetic...
Extreme warming at the end of the Permian period induced profound changes in marine biogeochemical cycling and animal habitability, leading to the largest...
University of Exeter’s Dr. Adrien Morison and colleagues have shown how vast ice forms have been shaped in Sputnik Planitia, a nitrogen-ice-filled basin...
A rare upper-atmosphere phenomenon called Strong Thermal Emission Velocity Enhancement (STEVE) has been well documented by amateur aurora watchers from...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have identified a dense, ultra-short-period sub-Earth planet transiting the bright,...
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and several ground-based telescopes, astronomers have discovered and confirmed a...
Juno launched on August 5, 2011 and successfully entered Jupiter’s orbit on July 4, 2016. During each of the spacecraft’s 37 passes of Jupiter to date,...
Using the Immersion GRating INfrared Spectrometer (IGRINS) at the Gemini South Observatory on Cerro Pachon, Chile, astronomers have measured carbon-to-hydrogen...
A team of researchers from the United States and Austria has analyzed remnants of ancient asteroids and modeled the effects of their violent collisions...
Observations by the NASA/ESA Hubble Space Telescope in far-ultraviolet light of Jupiter’s icy moons were used in the past to detect molecular oxygen...
Using high-resolution spectra obtained with GRACES at the Gemini North Observatory, astronomers have detected ionized calcium in the atmosphere of the...
The surface pressure on the dwarf planet Pluto is decreasing and that its nitrogen atmosphere is condensing, forming ice on the dwarf planet’s surface,...
In a paper published this week in the journal Astrobiology, researchers focused on the possible existence of the Earth-like phototrophy — the process...
Archaeologists have found evidence that in 1650 BCE (Middle Bronze Age), a cosmic airburst destroyed Tall el-Hammam, an ancient walled city in the Jordan...
Astronomers have discovered a highly-irradiated gas giant exoplanet in close-in, highly misaligned orbit around a bright star called TOI-1518.
An artist’s...
Using high-resolution observational of two very similar globular clusters, Messier 3 and Messier 13, astronomers have found an unexpected overabundance...
Annular modes explain much of the internal variability of Earth’s atmosphere but have never been identified as influential on other planets.
Mars has...
Titan, Saturn’s icy moon, is an ideal planetary body to study prebiotic chemistry, origins of life, and the potential habitability of an extraterrestrial...
