Researchers have made the first direct detection of atomic oxygen in the atmosphere of Venus. Some say it builds the case the planet was more hospitable in the past.
Most of what we know about Enceladus and its ice-covered ocean comes from the Cassini mission. New research based on Cassini data strengthens the idea that Enceladus has the chemicals necessary for life.
Two NASA space telescopes teamed up to scrutinize a distant galaxy and discovered something mind-boggling: a gargantuan black hole inside a galaxy that’s more than 13 billion years old.
Most meteorites from Mars are just a few hundred million years old, and likely come from relatively recent volcanic events such as the eruptions on the largest volcano in the solar system, Olympus Mons.
A system of seven sweltering planets has been revealed by continued study of data from NASA's retired Kepler space telescope: Each one is bathed in more radiant heat from their host star per area than any planet in our solar system.
Long ago, an alien planet crashed into Earth – causing a collision so big the debris formed the Moon and left mysterious remnants lodged deep in the Earth’s mantle.
Scientists have observed the creation of rare chemical elements in the second-brightest gamma-ray burst ever seen -- casting new light on how heavy elements are made.
Fine dust suspended in the atmosphere may have played a significant role in the extinction of dinosaurs after all.
Astronomers confirm the existence of an infrared (IR) aurora on Uranus. This could help astronomers identify exoplanets that might support life, a large number of which are icy worlds.
With only one habitable planet (Earth) and one technologically advanced civilization (humanity) as examples, scientists are still confined to theorizing where other intelligent life forms could be.
Two new papers show a 150 kilometer-thick layer of molten silicate rock at the base of the mantle envelopes Mars' liquid iron-alloy core.
A recent study suggests that Venus, typically viewed as a fiery wasteland, may have experienced Earth-like plate tectonics in its distant past.
Researchers using the NASA/ESA/CSA James Webb Space Telescope's NIRCam (Near-Infrared Camera) have discovered a high-speed jet stream sitting over Jupiter's equator, above the main cloud decks.
A recent study examines the discovery of what astronomers are dubbing "ultra-fast radio bursts", a new type of fast radio bursts (FRBs) that the team determined lasts for a mind-boggling ten millionths of a second or less.
Crystals brought back from the Moon by Apollo astronauts in 1972 push back the age of the moon by 40 million years, to at least 4.46 billion years old.
