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...
Hycean worlds are composed of water-rich interiors with massive oceans underlying hydrogen-rich atmospheres; with densities between those of rocky super-Earths...
Individual regional dust events can boost planetary water loss by a factor of five to ten and represent an important driver of atmospheric evolution on...
On July 14, 2021, the Subaru-Asahi Sky Camera on the 8.2-m Subaru Telescope at the summit of Maunakea, Hawai’i, captured a rare meteor outburst associated...
The L 98-59 planetary system contains two non-transiting planets and three transiting terrestrial planets, one of which is a warm rocky world with half...
