Curves and s-shaped lines seen on an image of a galaxy cluster.

Asteroid trails in Abell 370 lithograph front

The Hubble Space Telescope encountered a local group of photobombers while capturing this breathtaking image of a galaxy cluster known as Abell 370. A swarm of white streaks appears to have invaded the sea of gravitationally bound galaxies that make up the distant cluster. The curved and s-shaped streaks seem to glide through the cluster of several hundred galaxies. In reality, these objects are trails left on the image by nearby asteroids, located only about 160 million miles away in our own solar system. In contrast, Abell 370 is around 4 billion light-years distant.
