Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, if more detailed analyses verify preliminary observations from the James Webb ...

Mars’s atmosphere may have once been hundreds of times thicker than it is today, acting as a blanket that protected it from frequent asteroids that ravaged other planets. While the sun and most ...

A rocky planet in the Milky Way galaxy may have an atmosphere, raising the possibility that life could exist on its surface, according to experts. TRAPPIST-1e, a planet belonging to a collection of ...

Aug. 20 (UPI) --NASA is planning to launch TOMEX+ rocket mission to study the turbulence where Earth's atmosphere ends and outer space begins sometime over the next two weeks. The earliest the agency ...

JWST observations of exoplanet TRAPPIST-1d reveal a lack of a substantial, Earth-like atmosphere, as indicated by a "flat" spectral signature lacking typical atmospheric molecule fingerprints (e.g., ...

"Being able to send something out there would enable us to take a lot more precise data than we currently can." Self-lofting devices propelled by sunlight have been tested for the first time in ...

Researchers have demonstrated a lightweight disc-like device that can float in the mesosphere, a part of the atmosphere between 30 and 60 miles above Earth’s surface. The proof-of-concept device was ...

Between 30 and 60 miles above Earth’s surface lies a largely unstudied stretch of the atmosphere. It’s too high for airplanes and weather balloons, too low for satellites and nearly impossible to ...

Harvard SEAS researchers have tested and validated lightweight nanofabricated structures that can passively float in the mesophere, which is about 45 miles above Earth’s surface. The devices levitate ...

If you have seen a bright light streak across the sky, you have likely seen a meteor. Meteors are rocks from space that hit Earth's atmosphere and are commonly referred to as falling stars or shooting ...

Due to the lapse in federal government funding, NASA is not updating this website. Exhaust from a single Moon lander can briefly dominate the lunar atmosphere nearby. Molecules around the Moon are so ...
