NASA's DART mission didn’t just change the orbit of Dimorphos, the asteroid it hit. It changed the orbit of the larger ...

In 2020, astronomers discovered a violent cosmic event that has led them to rethink how extreme pairs of astronomical objects form. These pairs are capable of producing powerful cosmic collisions.

NASA’s DART mission changed the Dimorphos' asteroid orbit around the Sun, proving spacecraft impacts could help defend Earth.

NASA’s DART mission proved that a spacecraft can nudge an asteroid system in space, offering a real test of planetary defense. NASA’s DART (Double Asteroid Redirection Test) spacecraft changed the ...

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an ...

Earth’s orbit around the Sun is not circular, but an ellipse that is slightly elongated with an eccentricity of 0.017. (An eccentricity of 0 is a circle, while the dwarf planet Pluto has a relatively ...

Did you know that satellites are constantly falling? To understand how satellites stay in orbit, imagine standing on a very tall mountain and throwing a ball straight out in front of you. Gravity ...

An asteroid that NASA used for target practice a few years ago was nudged into a slightly different route around the sun, ...
