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.
Astronomers have detected silica in exoplanet atmospheres before. But this is the first time they’ve found particles of what appears to be pure quartz.
So-called chorus waves have been recorded at Earth, and Jupiter, and Saturn; and observed at Uranus and Neptune. Now, international scientists have detected them whistling around Mercury.
For the first time, artificial intelligence (AI) has searched for, detected, confirmed, classified, and announced a supernova discovery without any human intervention.
Fast radio bursts, or FRBs, are an astronomical mystery, with their exact cause and origins still unconfirmed. A recent research found several notable similarities between FRBs and earthquakes.
