(Phys.org) —NASA's Spitzer Space Telescope has spotted an eruption of dust around a young star, possibly the result of a smashup between large asteroids. This type of collision can eventually lead to the formation of planets.
Planetary scientists have discovered pieces of opal in a meteorite found in Antarctica, a result that demonstrates that meteorites delivered water ice to asteroids early in the history of the solar system. Led by Professor ...
Naturally formed quasicrystals—crystal-like solids with supposedly impossible symmetries—are among the rarest structures on Earth. Only two have ever been found.
Berkeley geologists have uncovered compelling evidence that an asteroid impact on Earth 66 million years ago accelerated the eruptions of volcanoes in India for hundreds of thousands of years, and that together these planet-wide ...
European experts have spotted one of the faintest asteroids ever found – a chunk of space rock thought to be about 100 m in diameter beyond the orbit of Mars.
Dinosaurs flourished in Europe right up until the asteroid impact that wiped them out 66 million years ago, a new study shows.
The grizzled asteroid miner is a stock character in science fiction. Now, a couple of recent events - one legal and the other technological - have brought asteroid mining a step closer to reality.
After a comet for Halloween, another Earthly holiday will be marked by a visit from a celestial body—this time a large asteroid zipping past on Christmas Eve, astronomers said Thursday.
Warming pulses in ancient climate record link volcanoes, asteroid impact and dinosaur-killing mass extinction
A new reconstruction of Antarctic ocean temperatures around the time the dinosaurs disappeared 66 million years ago supports the idea that one of the planet's biggest mass extinctions was due to the combined effects of volcanic ...
