A crater in western Australia was formed by a meteor strike more than 2.2 billion years ago and is the world's oldest known impact site, new research published Wednesday shows.
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, ...
Deep below the Earth's surface lies a thick rocky layer called the mantle, which makes up the majority of our planet's volume. While Earth's mantle is too deep for humans to observe directly, certain meteorites can provide ...
The Earth's Cenozoic Era began 66 million years ago with a bang—and with the last mass extinction event on Earth until now. The meteorite impact that marked the end of the Cretaceous Period and the beginning of the Cenozoic ...
A team of researchers with members from Singapore, the U.S., Thailand and Laos has concluded that the impact point of a meteorite that struck the Earth approximately 790,000 years ago lies buried beneath a volcanic field ...
Fortunately for today's scientists, Apollo-era leaders had the foresight to save much of the 842 pounds (382 kilograms) of Moon soil and rocks retrieved by NASA astronauts 50 years ago for future generations. They figured ...
There is not enough time for more close study of all fireballs observed in the sky. The observation of a bright phenomenon reveals that a meteoroid has entered the atmosphere from space, but does any part of it end up on ...
The isotopic composition of meteorites and terrestrial planets holds important clues about the earliest history of the solar system and the processes of planet formation.
Some of the Earth's building material was stardust from red giants, researchers from ETH Zurich have established. They have also explained why the Earth contains more of this stardust than the asteroids or the planet Mars, ...
Chemolithotrophic microorganisms derive their energy from inorganic sources. Research into the physiological processes of these organisms—which are grown on meteorite—provides new insights into the potential of extraterrestrial ...
