Stars have life cycles. They’re born when bits of dust and gas floating through space find each other and collapse in on each other and heat up. They burn for millions to billions of years, and then they die. When they die, they pitch the particles that formed in their winds out into space, and ...
Scientists believe they have discovered the site of the biggest meteorite impact ever to hit the British Isles. Evidence for the ancient, 1.2 billion-year-old meteorite strike was first discovered in 2008 near Ullapool, N.W. Scotland, by scientists from Oxford and Aberdeen Universities. The thickness and extent of the debris deposit they found suggested the impact ...
Earth is bombarded every year by rocky debris, but the rate of incoming meteorites can change over time. Finding a collection scattered on the planet’s surface can be challenging, especially if you are interested in reconstructing how frequently they land. Now, researchers have uncovered a wealth of well-preserved meteorites that allowed them to reconstruct the ...
Astronomers believe planets like Jupiter shield us from space objects that would otherwise slam into Earth. Now, they’re closer to learning whether these also guard solar systems elsewhere in the galaxy. A UCR-led team has discovered two Jupiter-sized planets about 150 light years away from Earth that could reveal whether life is likely on the ...
Observers watching January’s total eclipse of the Moon saw a rare event, a short-lived flash as a meteorite hit the lunar surface. Spanish astronomers now think the space rock collided with the Moon at 61,000 km/h, excavating a crater 10 to 15 meters across. Prof. Jose Maria Madiedo of the University of Huelva, and Dr. ...
Near Earth Objects (NEOs) are small solar system bodies whose orbits sometimes bring them close to the Earth, potentially threatening a collision. NEOs are tracers of the composition, dynamics, and environmental conditions throughout the solar system, and of the history of our planetary system. Most meteorites come from Near Earth Objects, which are thus one ...
