This video begins with an image of the whole night sky, before zooming in to the constellation of Hydra and the curious pair of galaxies catalogued as NGC 3314. These two galaxies are actually separated by around 20 million light years, even if from our vantage point they look like they are in the midst of a collision. The video ends with detailed Hubble observations of the two galaxies.
