Like everything else in the universe, galaxies are born, live and die in the end, and with incredibly powerful tools like the Hubble Space Telescope, we can observe different galaxies in virtually every phase of their lives.
One of the latest observations has just been published on the Hubble website and contains the Starburst Dwarf galaxy ESO 495-21. His name may not have the personality, but he balances it with a violent heart that quickly emits newborn stars. The galaxy is full of big stars that are all quite young, and there is no sign of slowing down.
As the Hubble story explains, the galaxy is full of so-called super star clusters or areas of extremely high star density. The massive stars in these areas are relatively young for galactic proportions ̵
Scientists have a pretty good idea. "The ESO 495-21 not only houses the cosmic fireworks that are super-star clusters, but may also be a supermassive black hole in the core," explains the Hubble Group. "Astronomers know that almost every large galaxy houses such an object in its center, and the bigger the galaxy is, the more massive the black hole is in general."
ESO 495-21 is so incredibly far away that it is actually visited is not even imaginable at this point. It is located about 30 million light-years away, which means that we actually see what the galaxy looked like 30 million years ago, not its present state. Even if we could move forward quickly, as the galaxy looks today, she would still be quite young and would probably still regularly make new stars.
