Early predictions suggested a 1% chance of a collision with Earth, a figure that was later revised to a remarkably low 0.004% ...

NASA’s DART mission slammed into the asteroid Dimorphos to test planetary defense. But weeks later, its orbit kept ...

When two worlds collide, they leave more than the shambles of dusty ejecta. Astronomers have detected light from a post-collision remnant, providing the best evidence so far for planetary-scale ...

A planetary collision afterglow and transit of the resultant debris cloud. Nature, 2023; 622 (7982): 251 DOI: 10.1038/s41586-023-06573-9; Cite This Page: MLA; APA; Chicago; University of Bristol.

Astronomers believe a planetary body collided with Pluto early in its history to create a gigantic heart-shaped feature on the dwarf planet. CNN values your feedback 1.

The idea that a giant planetary crash formed the Moon has been around since the 1970s; it’s known as the giant-impact hypothesis. But there have been some problems with the model.

The afterglow resulting from the planetary collision, as described in the study, took approximately 2.5 years to disrupt the typical starlight emitted by ASASSN-21qj.

The collision of a large impactor with Earth can supply the ... Planetary scientists need to double modelling efforts of the Earth–Moon system and identify chemical signatures in lunar and ...

NASA’s Spitzer Space Telescope has picked up on what seems to be evidence of two planets impacting and then exploding in a oh-dear-God-it’s-like-the-Death-Stars-all-over-again-no-no ...

Two planets may have crashed together recently, resulting in one planet that's weirdly hot for its size. The planet 2M1207B, 170 light years from Earth, ...

Planetary defense refers to the effort to monitor and protect Earth from asteroids, comets and other objects in space.
