Water is made of two hydrogen atoms and one oxygen atom, hence its H2O formula. In typical water molecules, though, those hydrogen atoms have just one...
Using data from the ChemCam instrument on NASA’s Curiosity rover, planetary scientists found minerals with high amounts of iron, manganese, and zinc...
A continent-like shelf beneath the Martian surface hints that a vast ocean once covered up to a third of Mars, reshaping the long-running debate over its...
New research from Rice University suggests sulfur keeps Mercury’s interior molten at lower temperatures, offering new clues to how the planet’s strange...
Observations from the Subaru Telescope on January 7, 2026, revealed a surprisingly low carbon dioxide-to-water ratio, suggesting the composition of the...
A new statistical analysis of archival sky surveys from the early Cold War has found that mysterious, short-lived bursts of light in the night sky were...
The Jovian system has four large moons, including the largest moon in the Solar System, Ganymede, whereas the Saturnian system is dominated by one giant...
A new nanoscale analysis of the Bennu sample OREX-800066-3 returned by NASA’s OSIRIS-REx mission shows that organic compounds and minerals cluster into...
New computational simulations suggest ice-giant planets like Uranus and Neptune harbor a quasi-one-dimensional superionic state of carbon hydride that...
Astronomers using the Vera C. Rubin Observatory have discovered over 11,000 new asteroids, including hundreds of trans-Neptunian objects and 33 previously...
A new analysis of data from NASA’s Parker Solar Probe shows that protons and heavy ions react differently to solar magnetic reconnection events, suggesting...
New findings from Neretva Vallis, an ancient river channel that once transported water into Jezero crater on Mars, reveal unusually high nickel levels...
A new analysis of isotopic signatures across planets and meteorite parent bodies suggests our home world formed entirely from inner solar system material,...
By combining infrared observations from the NASA/ESA/CSA James Webb Space Telescope with visible-light imagery from the NASA/ESA Hubble Space Telescope,...
On its way to Jupiter, ESA’s Juice spacecraft briefly turned its gaze toward a rare interstellar visitor, 3I/ATLAS, capturing valuable data from an object...
The breakup of C/2025 K1 (ATLAS), captured by the NASA/ESA Hubble Space Telescope, opens a window into how fragile comet nuclei evolve and collapse.
These...
Using a vast catalog of Sun-like stars built by ESA’s Gaia mission, astronomers have found strong evidence that our home star traveled outward with thousands...
