Polymers in meteorites provide clues to early solar system

Many meteorites, which are small pieces from asteroids, do not experience high temperatures at any point in their existence. Because of this, these meteorites provide a good record of complex chemistry present when or before ...

Earth's meteorite impacts over past 500 million years

For the first time, a unique study conducted at Lund University in Sweden has tracked the meteorite flux to Earth over the past 500 million years. Contrary to current theories, researchers have determined that major collisions ...

Solar wind from the center of the Earth

High-precision noble gas analyses indicate that solar wind particles from our primordial Sun were encased in the Earth's core over 4.5 billion years ago. Researchers from the Institute of Earth Sciences at Heidelberg University ...

Asteroid that hit Botswana in 2018 likely came from Vesta

An international team of researchers searched for pieces of a small asteroid tracked in space and then observed to impact Botswana on June 2, 2018. Guided by SETI Institute meteor astronomer Peter Jenniskens, they found ...

Scientists find carbon-rich liquid water in ancient meteorite

Water is abundant in the solar system. Even beyond Earth, scientists have detected ice on the moon, in Saturn's rings and in comets, liquid water on Mars and under the surface of Saturn's moon Enceladus, and traces of water ...

Baked meteorites yield clues to planetary atmospheres

In a novel laboratory investigation of the initial atmospheres of Earth-like rocky planets, researchers at UC Santa Cruz heated pristine meteorite samples in a high-temperature furnace and analyzed the gases released.
