When NASA crashed a spacecraft into the asteroid moonlet Dimorphos in 2022, it altered both Dimorphos' orbit around its ...

Four years ago, NASA purposely smashed a spacecraft into a small asteroid to see if they could deflect it—a test to prove humanity could protect Earth from threatening space rocks.

In a pioneering achievement for planetary defense, NASA’s DART (Double Asteroid Redirection Test) mission has proven its ...

NASA’s Double Asteroid Redirection Test, known as DART, did more than shove a small asteroid into a tighter loop around its ...

In September 2022 NASA smashed a spacecraft into an asteroid. Called Dimorphos, the rock is the smaller asteroid in a binary ...

In September 2022, NASA’s DART spacecraft rammed into the asteroid moonlet Dimorphos at nearly 15,000 miles per hour (24,000 ...

Astronomers have analyzed the images collected by the Hubble Space Telescope (HST) to investigate a galactic open cluster ...

The catalogue of all the new 128 events observed by LIGO, Virgo and KAGRA from May 2023 to January 2024 is being published. It reveals an even greater variety of binary pairs producing gravitational ...

Astronomers report the rapid transition of WOH G64 from a red supergiant to a yellow hypergiant, based on photometric and spectroscopic observations published in Nature Astronomy.

In the distant reaches of the solar system are many icy objects that resemble snowmen. Now, a new study reveals the simple ...

A proposed five-satellite Cosmic Positioning System could measure cosmic distances directly and help address discrepancies in the Hubble constant through solar system–scale triangulation.
