Once a realm of imagination and stargazing, the Solar System has now been revealed in stunning clarity through decades of ...

An astrophotographer has captured an extremely rare and "difficult" photo of a solar flare exploding from the sun at the ...

In 1977, NASA launched the Voyager probes to study the Solar System's edge, and the interstellar medium between the stars. One by one, they both hit the "wall of fire" at the boundaries of our ...

NASA discovered a huge lake on Jupiter The NASA Juno mission focuses on exploring Jupiter, the largest planet in our solar system, and the primary goal is to collect data about the planet’s water ...

NASA's Webb Captures First Direct Images Of Carbon Dioxide Outside Solar System This finding provides compelling evidence that the giant planets in HR 8799 formed through core accretion, a process ...

In contrast to things within the solar system that are tightly bound in the Sun's orbit by its gravity, things within the Oort Cloud sit at the far edges of the Sun's grip.

NASA's Parker Solar Probe hurtled through the sizzling solar atmosphere and passed within a record-breaking 3.8 million miles of the sun's surface.

NASA kept them going, albeit after turning off instruments that wouldn’t produce interesting data without planets to observe. Years passed, and the Voyagers trekked ever outward, swimming toward ...

After more than four months in space, NASA's Advanced Composite Solar Sail System (ACS3) has successfully deployed its solar sail, achieving a major milestone in space propulsion.

The space agency has pushed back the spacecraft’s return to an unspecified date in July, to give it more time to look into the problems that beset the vehicle on its journey into orbit.

Scaled-up solar sails, however, will be pretty massive—NASA is currently planning future designs as large as 5,400-square-feet, or roughly the size of a basketball court.

NASA’s experimental solar sail is ready to take flight in Earth orbit, using the pressure of sunlight to test a new way of propulsion through the cosmos. The Advanced Composite Solar Sail System ...
