The incredible shining phenomenon in the highest reaches of Earth's atmosphere.

Red Sprites, Blue Jets, Gigantic Jets and Elves!

A brief streak of light in the night sky caused by a small object, maybe the size of a pebble or even a speck of dust, burning up as it enters the upper atmosphere from space.

A feature from NASA’s Ames Research Center in Silicon Valley originally posted on October 14, 2016.

While more research is needed, Smith and others are fascinated by the possibility that airborne microbes could also be found elsewhere in the solar system, and beyond.

The night sky is full of planets, satellites, and cosmic objects we can see with our eyes and telescopes. In between all that material there’s a huge amount of invisible matter and the vast majority of it is called plasma. Follow along...

The exoplanet WASP-76 b, an ultra-hot gas giant, may be even hotter than scientists realized.

High above the thin Martian skies, NASA’s MAVEN spacecraft is carrying out a mission: determine how Mars lost its early atmosphere, and with it, its water. While previous Mars orbiters have peered down at the planet’s surface, MAVEN...

When you take a look at Mars, you probably wouldn't think that it looks like a nice place to live. It's dry, it's dusty, and there's practically no atmosphere. But some scientists think that Mars may have once looked like a much...

Learn about the two main layers of the atmosphere: the troposphere and the stratosphere. The troposphere is full of weather and ‘bad’ ozone, and above that, is the stratosphere, where ‘good’ ozone protects us against dangerous UV light....

Climate patterns and storms on Jupiter can have striking similarities to those on Earth. One such pattern is a four-year temperature cycle in the Jovian upper atmosphere called the QQO.



This cycle has a little...

GOLD is a new NASA science mission that launches in January 2018 to explore Earth’s interface to space!



GOLD stands for Global-scale Observations of the Limb and Disk. It will inspect the dynamic region of near-Earth space...

Ancient riverbeds, crater lakes and flood channels all attest to Mars's warm, watery past. So how did the Red Planet evolve from a once hospitable world into the cold, dry desert that we see today? One possibility is that Mars lost...

The Martian climate remains one of the solar system's biggest mysteries: although cold and dry today, myriad surface features on Mars carved by flowing water attest to a much warmer, wetter past. What caused this dramatic transition?...
