For the first time on a global scale, 20 years of observations on Mars have been condensed into a single study led by ...

The James Webb Space Telescope has spotted a 'rogue' cosmic object barrelling through our galaxy without a star, and covered ...

INDIANA, USA — Look up mid-March, and you'll see the moon turn blood red. The next total lunar eclipse will occur on the night of March 13-14 (Thursday-Friday) across the western hemisphere as the ...

While this fraction is relatively low given how common super-Earths and mini-Neptunes are, it implies an occurrence rate of approximately one Earth-like planet per 300 sun-like stars." ...

Over time, these shifts could limit the number of satellites that can reliably operate in Earth’s orbit. Led by MIT, the new study indicates that emissions of carbon dioxide and other greenhouse gases ...

The continued release of greenhouse gases into Earth's atmosphere could increase the longevity of space junk in low Earth orbit, a new paper reveals. Under a high-emissions scenario, this could mean a ...

Part of the greenhouse effect that warms the air near Earth’s surface also cools the upper parts of the atmosphere where space starts and satellites zip around in low orbit, That cooling also ...

Earth’s atmosphere doesn’t suddenly give way to the vacuum of space but gets dramatically thinner at a point known as the Kármán line, roughly 100 kilometers up. Objects that orbit the ...

NASA astronaut Butch Wilmore has captured an image of a blue jet sprite in the Earth's atmosphere, a rare phenomenon only confirmed in recent years. Astronaut and keen astrophotographer Don Pettit ...

In contrast, during a total solar eclipse — which is preceded by a partial eclipse — the moon completely covers the sun, ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed. Primordial helium from the ...

Scientists have attributed this evolutionary boom to increased oxygen levels in Earth’s atmosphere and in shallow ocean waters. And now, research published Tuesday in the journal Geology ...
