Recent expanded analysis much more strongly suggests that Callisto hosts a subsurface ocean.
A team of researchers has found evidence of salt minerals in samples recovered from Ryugu during the initial phase of Japan's Hayabusa2 mission.
The planet, WASP-121b, is some 900 light-years away in the constellation Puppis. The team has now probed deep inside Tylos's atmosphere and revealed distinct winds in separate layers, forming a map of the atmosphere's 3D structure.
An international team of researchers have discovered hidden structures within whale songs that exhibit striking parallels to human language.
New images, taken over 16 min on January 17, 2025 by the Mastcam instrument on NASA's Curiosity rover, show noctilucent, or twilight clouds, in the atmosphere of Mars.
In 1983, the theoretical physicist Brandon Carter concluded that the time it took for humans to evolve on Earth -- relative to the total lifespan of the Sun - suggests that our evolutionary origin was intrinsically unlikely.
Earth must have experienced something exceptional 10 million years ago. A strange increase in the radioactive isotope beryllium-10 was found in rock samples from the floor of the Pacific Ocean.
Meteoroids striking Mars produce seismic signals that can reach deeper into the planet than previously known.
The Alpha Centauri (AC) star system is our nearest stellar neighbour and it is moving toward us, presenting an excellent opportunity to study how material might move between Solar Systems.
A Canadian-led team of international astronomers has made a groundbreaking discovery about how young planets form and grow using a creative approach with unique tools of the James Webb Space Telescope.
On 13 February 2023, an undersea detector off the coast of Sicily picked up a record-breaking neutrino event. The particle's energy was estimated to be a whopping 220 petaelectronvolts.
An international team has confirmed the discovery of a super-Earth orbiting in the habitable zone of a nearby Sun-like star.
In a groundbreaking use of teleportation, critical units of a quantum processor have been successfully spread across multiple computers.
Last year, a study proposed that deposits of carbon dioxide ice and other carbon-bearing molecules on Uranus's moon Ariel likely originated from chemical processes inside the moon—possibly even from a subsurface ocean.
The ongoing swarm of earthquakes near Santorini continues to baffle scientists.
