Tiny bits of Earth’s atmosphere have been drifting to the moon for billions of years, guided by Earth’s magnetic field. Rather than blocking particles, the magnetic field can funnel them along ...
The moon's surface may be more than just a dusty, barren landscape. Over billions of years, tiny particles from Earth's atmosphere have landed in the lunar soil, creating a possible source of ...
Earth's atmosphere may be seeding the Moon with water, as hydrogen and oxygen ions could bond into water molecules in lunar soil.

Scientists reveal when Earth could lose its oxygen-rich atmosphere, and it’s sooner than expected
A new scientific model suggests that Earth’s oxygen-rich atmosphere may last for around 1 billion more years before a dramatic transformation removes the conditions that support complex life. The ...
Planet Earth has some pretty great qualities going for it. (Negative reviews mostly revolve around the staff and clientele.) Pretty high on the list of positives is a richly oxygenated atmosphere. But ...
NASA-funded studies suggest Earth’s climate has been influenced by both the Sun’s travels through dense regions of the Milky Way and the violent superflares of its youth. Those events may help explain ...
Atmospheric circulation governs weather and climate, but it also carries angular momentum. When winds shift or mass ...
Our species likes it cold. Homo sapiens evolved in — and still inhabits — one of Earth’s rare and fragile ice ages, periods distinguished not by an abundance of saber-toothed cats and woolly mammoths ...
If global warming continues, the Earth will eventually become a planet where humans cannot live.”In articles dealing with ...

Ocean chemistry on ancient Earth could help scientists search for life on alien worlds
A new look at ancient rocks suggests that a self-sustaining nutrient cycle in ancient oceans helped keep Earth's atmosphere rich in oxygen for millions of years.
When Did Oxygen Change the Earth? — Episodes 30 to 34Oxygen now accounts for about one-fifth of Earth's atmosphere.We use ...
