This is one data set that a federal agency is keen to make public.
NASA has made it possible to sample our planet's chorus while potentially safeguarding costly spacecraft from being damaged by "killer" radiation.
If it rains while the sun shines, you get a rainbow. When the sun shoots a filament toward Earth, you get an aurora. Amazing NASA cause and effect photos over last weekend, from Sun to Yukon.
Global Earth scientists remain a challenge - but with the opening of a new data access facility, NASA hopes to launch the next chapter of discovery.
NASA was successful in using robots to repair and refuel satellites orbiting the Earth, saving humans from doing the onerous and dangerous task.
New video released by NASA shows Earth-sized tornadoes on the sun's surface.
It's 600 light years away, twice the size of Earth and has the unassuming name of Kepler-22b. But Nasa says that the planet is the first we've found, apart from our own, that could have liquid water on its surface — in other words, it orbits its star in a habitable zone.
A NASA-sponsored study found that 6-month-long spaceflights were causing a spectrum of eye abnormalities. Superfocus adjustable glasses allows astronauts (and aging earth-dwellers) to set the focus.
NASA predicts that the debris is due to fall back to Earth sometime between Sept. 23 and 25th.
NASA scientists for the first time can track the effects of a solar storm on Earth, offering new advancements in our ability to predict space weather and how it will impact our electronics.
The biggest threat to Earth? Something hitting it, said Ed Lu, a former NASA astronaut and chairman of the B612 Foundation.
NASA announced that it has discovered that Earth is following an asteroid as they both circle the sun.
Atlantis's mission to the International Space Station is the final flight in the 30-year-old space shuttle programme, which has pushed technology to its limits
This is actually some of the real science that's been fueling the global warming and client change debates.
At the polar ice caps, NASA scientists are studying global warming from the air. We talk with Steve Hipskind, chief of the agency's Earth Sciences division, to learn more.
Network down? It's the Sun what done it...
The Feb. 27 earthquake that killed more than 700 people in Chile probably shifted the Earth's axis and shortened the day, a NASA scientist said.
NASA scientist Chris McKay takes his work to the far reaches of planet Earth, studying extreme conditions in order to find life on other planets.
