In today's image, we see the galaxy NGC 2936, known as the Porpoise Galaxy as imaged by the Hubble Space Telescope. This galaxy is in the process of colliding with the elliptical galaxy below and t the right of it. Galaxy collisions are a slow process, taking hundreds of millions or even a billion years to complete. However, this is the process by which we believe galaxies grew from very small things right after the Big Bang to the large spiral and elliptical galaxies that we see today.
