I bet you can recognize what those elliptical figures are. That's right, they are galaxies! Now think of this, Earth is part of the Milky Way galaxy and in the picture we can see more than 20 galaxies. This cluster of galaxies is called the Coma Cluster of Galaxies. Taken by the Hubble Space Telescope in 2006, astronomers have now been able to study how galaxies are formed. The Coma Cluster of Galaxies are many light years away, which is why astronomers have not been able to observe these galaxies until the Hubble Space Telescope. On the picture, one can see more fainter galaxies in the distance. This means that there are more galaxies that we are not able to see with a telescope and are just waiting to be discovered.
