NASA’s Carruthers Geocorona Observatory studies Earth’s exosphere, capturing ultraviolet images to monitor atmospheric ...

Look up on a clear night and you'll see the streaks of our new space age. What you don't see is the growing fallout for the atmosphere that keeps us alive.

Finding Earth-like planets orbiting sun-like stars and identifying signs of life such as oxygen or water is a major goal in ...

We like to think of Earth and outer space as distinct places. One down here and one up there. But this isn't really true. The boundary is very porous. Tonnes of celestial material, mostly grain-sized, ...

Researchers have detected measurable traces left in the upper atmosphere when a rocket stage burns up, finding about ten times more lithium atoms than normal at around 96 kilometres, roughly 20 hours ...

Space junk falling out of orbit and crashing toward Earth is a growing threat. Indeed, old satellites and spacecraft parts reenter our planet’s atmosphere more than three times a day. When these ...

The study highlights how letting rocket debris burn up in the atmosphere is not a consequence-free approach to orbital ...

Space debris might sound like something from science fiction, but it's becoming a daily reality for our planet. Every hour of every day, chunks of old satellites and rocket parts plummet through our ...
