A well-known sight sighted by the Hubble Space Telescope



  Hubble Space Telescope Galaxy IC 4653

Credit: ESA / Hubble and NASA, D. Rosario (CEA, University of the Durham) [19659006] This image from the Hubble Space Telescope Hubble Space Telescope shows IC 4653, a galaxy just over 80 million light-years from Earth. This may sound like a long distance, but it is not so far in space. At these types of distances, the types and structures of the objects we see are similar to those in our area.

The swirling arms of the galaxy tell us a story about what's going on inside this galaxy. Bright blue spots mark the sites of active star formation. Studying the structures of other galaxies is a key way to learn about our own structure, given that humans cannot leave the Milky Way to look back and see what it looks like from the outside. It helps to compare our observations of our galaxy with those of nearby galaxies that we can see in their entirety.
