Our sun is an incredible fusion engine. From the surface of earth, we see it as a mere ball of light, but through amazing high-res imaging capabilities, we can observe real solar activities thanks to NASA's Solar Dynamics Observatory.

Scientists have recreated the complex flow of superheated gas inside the surface of the surface of our star in an effort to predict violent outbursts called Coronal Mass Ejections.

NASA's Solar Dynamics Observatory has brought us front row center to a show filled with radiant bursts and dark mysteries. SDO captures images of the sun in 10 different wavelengths, highlighting a range of surface temperatures. These show specific structures.... such as solar flares -- giant exp...

The Mars rover, Curiosity, is the latest in a long line of missions to Mars: landers sent to scoop its soil and study its rocks, orbiters sent to map its valleys and ridges.

They are all asking the same question. Did liquid water once flow on this dry and dusty world? Did it support life in an...

A beauteous rip through the solar sytem, based on NASA's Science on a Sphere program "The Wanderers." In ancient times, humans watched the skies looking for clues to their future and to aid in their very survival. They soon observed that some stars were not fixed, but moved in the sky from night...

We can build powerful rockets able to carry people and machines into orbit, or even vault them to the moon. But our fastest spacecraft don't hold a candle to the distances that define Interstellar Flight. So what's on the drawing boards? What futuristic designs and fuel options promise to one day...
