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.
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.
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.
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.
This new image of the protostar HH30 is in amazing new detail thanks to the JWST. The image shows the protoplanetary disk seen edge on, with a conical outflow of gas and dust, with a narrow jet blasting out into space.
Using the European Space Agency’s Euclid space telescope, astronomers have accidentally found a complete Einstein ring around a nearby galaxy known as NGC 6505.
In the months following massive solar storm in May, 2024, Earth was girded by two new, temporary radiation belts of high-energy particles, trapped by the planet's magnetic field.
January 2025 was 1.75°C above the pre-industrial level and was the 18th month in the last nineteen months for which the global-average surface air temperature was more than 1.5°C above the pre-industrial level.
