Collisions between galaxies, or [[galaxy merger]]s, have been observed directly by space telescopes such as Hubble and Spitzer. However, collisions in planetary systems including [[stellar collisions]], while long speculated, have only recently begun to be observed directly.

In 2013, an impact between minor planets was detected around the star NGC 2547 ID 8 by Spitzer and confirmed by ground observations. Computer modelling suggests that the impact involved large asteroids or [[protoplanet]]s similar to the events believed to have led to the formation of terrestrial planets like the Earth.<ref name="space.com"/>
