The gravity of a large object in space can keep a smaller object from spinning, a phenomenon called tidal locking. The discovery and characterization of...
Using data from ESO’s Very Large Telescope (VLT), NASA’s Spitzer Space Telescope, the Subaru Telescope, the Keck Telescope, the Gemini South and North...
It’s raining vaporized rock on WASP-178b, and KELT-20b has its upper atmosphere getting hotter rather than cooler because it is being sunburned by intense...
The atmosphere of Jupiter is enriched with heavy elements by a factor of about 3 compared to a protosolar composition. The origin of this enrichment and...
NASA’s Perseverance rover first recorded Martian sounds on February 19, 2021, the day after its arrival. These sounds fall within the human audible spectrum,...
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...
