A satellite launched to rescue NASA’s falling Swift Observatory won’t be able to complete its mission after all.

Researchers have found a clever new way to map a part of Earth’s upper atmosphere that is notoriously difficult to observe. Using orbital data from roughly 1,200 Starlink satellites, they ...

Researchers have created a dataset of the whole atmosphere, enabling new research to be conducted on previously difficult-to-study regions. Using a new data-assimilation system called JAGUAR-DAS, ...

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 ...

Experience a breathtaking and realistic simulation of a high-speed descent starting from the edge of space, plunging through ...

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 ...

“This isn’t what we expected at all,” researchers said of a Mega-Earth that defies planet formation theories.

According to a filing with the Federal Communications Commission on Tuesday, 472 Starlink satellites burned up in the atmosphere between December 2024 and May 2025, as SpaceX deorbited around 6% of ...

Scientists have detected promising evidence that a rocky planet located 49 light-years from Earth could have an atmosphere, potentially making it one of the most compelling places to search for ...

Astronomers have been studying rocky exoplanets for years, and have found several with characteristics similar to Earth. Credit: NASA, ESA, CSA, Leah Hustak (STScI) Still seeking proof of life outside ...
