Description

This image features enormous differences of scale.

On the left is Mirach, the bright center star of Andromeda only 200 ly away. On the right is Mirach's Ghost, an elliptical galaxy 7 million ly away! Peppered into the background around Mirach are even more distant galaxies, lending this image an enormous sense of depth. Captured on Deep Thought by Liam Yanulis.
