New research finds that despite large rivers and seas of liquid methane, Saturn's moon Titan seems mostly devoid of river deltas.
An international collaboration has published groundbreaking research, shedding light on the most significant increase in complexity in the history of life's evolution on Earth: the origin of the eukaryotic cell.
Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious.
New research led by University of Hawaii astronomers suggests our Universe may rotate - just extremely slowly.
The distribution of valley heads on Mars matches predictions for a climate that includes precipitation rather than just runoff from melting ice caps.
Astronomers at MIT have discovered a rocky exoplanet orbiting the bright K-dwarf star BD+05 4868A and observed variable transit depths that are characteristic of comet-like tails.
The fact that this bacteria so closely resembles that transition point, from two single cells with different genetics to one inseparable cluster, is fascinating: embryo comparisons have provided many clues about our evolutionary history.
In a new image from NASA’s James Webb Space Telescope, a galaxy named for its resemblance to a broad-brimmed Mexican hat appears more like an archery target.
A surprise discovery in Gale Crater is the component that was missing in the puzzle of Mars's climate history.
Slushy hail, made of water and ammonia, may form during lightning-packed storms, giving researchers fresh clues about what lurks beneath the planet’s colorful cloud tops.
A new analysis of the sky has finally confirmed where the missing half of the Universe's visible matter has been hiding.
A global study of over 66,000 people reveals that susceptibility to misinformation varies across age, gender, education, and political ideology.
Using a rare type of meteorite, enstatite chondrite, which has a composition analogous to that of the early Earth - researchers have found a source of hydrogen which would have been critical for the formation of water molecules.
Since the James Webb Space Telescope (JWST) began science operations, astronomers have observed galaxies that existed more than 13 billion years ago.
Four large language models (LLMs) were put through the Turing test. One model – OpenAI's GPT-4.5 – was deemed indistinguishable from a human more than 70% of the time.
