350 million light years away are two galaxies that seem to be on a collision course. This particular system of the galaxies is known as Arp 256. The picture of the image (above) taken by the Hubble Space Telescope shows tails of stars, dust and even stellar nurseries*. About four billion years from now, our galaxy too will presumably merge with the Andromeda galaxy.
* – Stellar nurseries are areas in space where dust and gas clouds compress to form stars.
