A visualisation of the huge, glowing planetary body produced by a planetary collision (Mark Garlick) Astronomers have seen the “afterglow” of two huge planets crashing into each other for the ...
Simulated collision of two neutron stars. A stellar collision is the coming together of two stars [1] caused by stellar dynamics within a star cluster, or by the orbital decay of a binary star due to stellar mass loss or gravitational radiation, or by other mechanisms not yet well understood.
The Kessler syndrome (also called the Kessler effect, [1] [2] collisional cascading, or ablation cascade), proposed by NASA scientists Donald J. Kessler and Burton G. Cour-Palais in 1978, is a scenario in which the density of objects in low Earth orbit (LEO) due to space pollution is numerous enough that collisions between objects could cause a ...
The asteroids will be around 6.8 million miles (11 million kilometres) from Earth when the collision happens. (PA Graphics) Dart will accelerate at about 15,000 miles per hour (24,140 kilometres ...
A collision 66 million years ago between the Earth and an object approximately 10 kilometers (6 miles) wide is thought to have produced the Chicxulub crater and triggered the Cretaceous–Paleogene extinction event that is understood by the scientific community to have caused the extinction of all non-avian dinosaurs.
A collision between giant asteroids likely occurred in a neighboring star system called Beta Pictoris in recent years, and two different space observatories are helping to tell the tale.
