Imagine waking up one morning to find that Earth’s atmosphere has vanished—gone, as if erased by an invisible hand. Suddenly, ...

Earth's atmosphere is a mixture of gases that are held in place by gravity. By far the largest component is nitrogen, which makes up nearly 80% of the atmosphere.

Earth's atmosphere is made of mainly nitrogen (~78%) and oxygen (21%), with trace amounts of other gases such as argon, water vapor, carbon dioxide, methane, ...

Our respondents are quick to point out the issues with using Earth’s rotation to get to a destination, not least the ...

Earth as oxygenator. Earth loses about 90 tons of gas—mainly hydrogen and helium—to space every day. That’s tiny compared to the mass of our atmosphere, so there’s no cause for alarm. But ...

The first wave of Starlink satellites are reaching the end of their five-year lifespans and burning up in droves.

Som and David Catling, a professor of earth and space sciences at the University of Washington, are proposing a radically different idea: that 2.7 billion years ago, Earth had a thin atmosphere ...

Early Earth's atmosphere may have been half as thick as it is today, new research suggests. Even so, the planet likely supported life, the scientists said.

On Earth, all that water vapor belched out of volcanoes condensed in the young atmosphere into liquid water, then fell to the surface as rain. Over eons, this formed the oceans.

First came the surprising discovery that Earth’s atmosphere is leaking. But for roughly 60 years, the reason remained a mystery. Since the late 1960s, satellites over the poles detected an ...
