Here are some downright chilling sounds recorded by several spacecraft. The sounds come from radio signals that are created by solar winds interacting with plasma that is wafting through our solar system.

For decades, planetary scientists have suspected that ancient Mars was a much warmer, wetter environment than it is today, but estimates of just how much water Mars has lost since its formation vary widely.

For all of you who were unable to view the historic super blood moon of September 27, 2015. This rare alignment of the Sun, Moon, and Earth won't happen again until 2033. With all the terrible things going on in the world today, we can sit back and admire the exquisite beauty of these celestial b...

Thirty-six years ago this month, on Sept. 5, 1977, the Voyager 1 spacecraft was launched from Cape Canaveral, Florida. On September 12, 2013, NASA officially confirmed that Voyager 1 had reached the interstellar medium in August 2012. This makes Voyager 1 the first spacecraft to exit our solar s...

Where did the moon come from? What is it made of? And what events created the distinctive pattern of light and dark on its surface? To find out, we have sent satellites out to crash onto its surface, astronauts to comb its craters and hillsides and collect rocks, and high-tech spacecraft to map i...

This video is an adaptation of the breezy Science on a Sphere production by supremely talented members of NASA's Scientific Visualization Studio. This video explores Jupiter's role as the 800 pound gorilla of our solar system, with stops on its fascinating moons and the big red spot. Additional v...

The Cassini Spacecraft swooped in for the last of five close encounters with one of the most beautiful moons in our solar system: Dione. After more than a decade exploring the Saturn system, the Cassini-Huygens mission must be regarded as one of the most successful science missions ever. It has a...

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...
