Saturn, the jewel of our solar system, has captivated the imagination of space enthusiasts and scientists alike for centuries. Thanks to NASA's Cassini spacecraft, we now have the privilege of ...

Objects that come from inside our solar system tend to move along a closed elliptical orbit, while interstellar objects follow a hyperbolic orbit, and move fast enough to be able to escape gravity.

These newly released images — taken closer to the Sun than we’ve ever been before — are helping scientists better understand the Sun’s influence across the solar system, including events that can ...

However, NASA has revealed updated information about its upcoming journey through the solar system. 3I/ATLAS is currently around 4.5 times as far from the sun as Earth is.

NASA has discovered 3I/ATLAS, an interstellar comet that' s ... It's officially the third known interstellar object to pass through our solar system, and it poses no threat to Earth.

Before it met the 30,000-50,000 kelvin wall at the edge of our Solar System, Voyager 1 took its final images.

Using a NASA supercomputer to run models, researchers led by SwRI astronomer David Nesvorny now believe that the Inner Oort cloud looks like a spiral disk, around 0.24 light-years across, with two ...

NASA's Advanced Composite Solar Sail System (ACS3) is still spinning through space uncontrollably. One of its boom arms has a bend as well.

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's Parker Solar Probe holds the title as the closest human-made object to the Sun. On Dec. 24, 2024, Parker made history by traveling just 3.8 million miles from the Sun's surface at a ...

But on Christmas Eve, NASA’s Parker Solar Probe flew around the sun. At around 6:53 a.m. EST on Tuesday, the probe flew within 3.8 million miles of our solar system’s beacon—closer than any ...
