'Earth wind' bathes the Moon with oxygen

Mon, 01/30/2017 - 05:00
To study the ancient history of the Earth, we should look to the moon. A new study from Japanese researchers reveals that for the past 2.4 billion years, the moon has been bathed in a stream of oxygen particles stripped from the Earth’s atmosphere. By combining measurements taken with the lunar orbiter Kaguya and studies of lunar rocks, researchers prove that Earth contributes it’s own unique whiff of elements to the moon’s surface. The findings adds substantial proof to the t

Fallout from an ancient asteroid collision still rains on Earth

Tue, 01/24/2017 - 05:00
Extraterrestrial objects are constantly bombarding Earth; thankfully the vast majority are microscopic. Thanks to the planet’s atmosphere, we live largely unaware of this celestial fusillade, which averages about 100 tons a day and mostly burns up long before hitting the ground. From the few that do make impact, researchers can gather clues about the composition of our solar system, with the goal of understanding how planets and other bodies emerged from an embryonic disk of dust and gas
