Early Mars had rivers, but the cause of the transition from a wet planet to dry remains unknown. Past Martian climate can be probed using the distribution...
One of the new images, taken by the Extreme Ultraviolet Imager (EUI) aboard the ESA/NASA Solar Orbiter spacecraft on March 7, 2022, is the highest resolution...
In a new paper in the Astrophysical Journal, a duo of astronomers from the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University...
In a study published on April 25, 2022 in the Astrophysical Journal Supplement Series, astronomers analyzed archival spectroscopic and photometric data...
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...
