Using a new probe that detects tiny amounts of moisture on sand grains, a team of researchers from Cornell University, the Ecole Polytechnique de l’Université...
The case for methane as a biosignature stems from its instability in the planet’s atmosphere. Because photochemical reactions destroy atmospheric methane,...
Each year, about 2 kg of helium-3, a rare isotope of helium gas, escapes from Earth’s interior, mostly along the mid-ocean ridge system. Helium-3 is...
A small near-Earth asteroid called 2022 EB5 disintegrated over the Norwegian Sea just two hours after its discovery on March 11, 2022.
An artist’s impression...
Using data collected by the Wide Field Camera 3 (WFC3) infrared spectrograph onboard the NASA/ESA Hubble Space Telescope, astronomers have obtained a detailed...
Saturn is unique among planets observed to date in that some of its aurorae are generated by swirling winds within its atmosphere, and not just from the...
According to new research from the Australian National University and the Queensland University of Technology, the supermountains formed twice in Earth’s...
The temperature of a planet’s atmosphere decreases with increasing altitude, unless a shortwave absorber that causes a temperature inversion exists....
Atmospheric lakes are long-lived pools of water vapor that occur over the western Indian Ocean and bring water to dry lowlands along East Africa’s coastline.
Long-lived...
Iodine, the same chemical added as a nutrient to table salt, is an atmospheric trace element emitted from oceans that efficiently destroys ozone. Low ozone...
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,...
