One of the nearby galaxies is our Milky Way galaxy. About 260 million light-years from Earth, it has long been of interest to astronomers and is the galaxy ESO 185–IG013. It is classified as a Blue Compact Galaxy–BCG, which shows intense star formation. It has an unusual blue color in visible light. Making it different from other galaxies that have a high scattering of stars. and emits more infrared light
Recently, astronomers working with the telescope NASA’s Hubble Space Telescope and the European Space Agency Latest images of galaxy ESO 185-IG013 revealed at ultraviolet wavelengths. Visible and infrared light have revealed details about this galaxy’s past. Hundreds of young star clusters were found. Many of them are less than 100 million years old. Many of the star clusters were also found to be only 3.5 million years old. Astronomers suspect that many of the young clusters in ESO 185-IG013 will not last long. This is because young star clusters often die after releasing too much gas. The large number of young star clusters indicates that the galaxy was part of a series of recent galactic collisions and mergers. The galaxy’s shocking structure is likely the result of the violent interaction of gas and dust during collisions.
Astronomers believe these blue galaxies will help shed light on galaxy formation and evolution that may have occurred billions of years ago.
