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 reconstructed changes in atmospheric density about 500 kilometers above Earth.
Add Yahoo as a preferred source to see more of our stories on Google. The Moon has no real atmosphere, but Earth has, in a sense, been generously trying to share its own for billions of years. A new study has found that our planet's magnetic field could be ...
Scientists made a first-of-its-kind discovery: key ingredients for life detected on a habitable-zone planet, upending long-held assumptions.
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 life-sustaining substances for future astronauts. But scientists ...
Low Earth orbit is getting crowded, and it's not just about the satellites and debris everyone can picture. Even hundreds of miles up, in air so thin
Operating a million or more data centers in space would mean a massive increase in air pollution from rocket launches and concentrations of toxic ash from reentering satellites.
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, which combines numerical modeling with observational data ...
This infographic shows the multiple layers of our atmosphere, extending from the ground up into space, and how the new dataset compares in coverage to those currently available. Credit: D.Koshin, K. Sato, S. Watanabe and K. Miyazaki, 2025/ Progress in Earth and Planetary Science (PEPS)
The outermost part of our planet’s atmosphere extends well beyond the lunar orbit – almost twice the distance to the Moon. A recent discovery based on observations by the ESA/NASA Solar and Heliospheric Observatory, SOHO, shows that the gaseous layer ...
