Like everything else in the universe, galaxies are born, live, and ultimately die, and thanks to incredibly powerful tools like the Hubble Space Telescope, we can see various galaxies at virtually every stage of their lives. of its newest observations was just published on the Hubble website and it features the dwarf starburst galaxy ESO 495-21. Its name may lack personality, but it does more than make up for it with a violent heart that quickly pumps out newborn stars. The galaxy is packed with big stars that are all quite young, and it shows no signs of slowing down.
As the Hubble story explains, the galaxy is packed with what scientists call super star clusters or areas with extremely high star density. The massive stars in these areas are fairly young by the galactic standards ̵
As for what lies at its very center, scientists have a pretty good idea. "As well as hosting cosmic fireworks that are super star clusters, ESO 495-21 may also harbor a supermassive black hole at its core," explains the Hubble group. "Astronomers know that almost every big galaxy hosts such an object at its center, and, in general, the larger the galaxy, the more massive the black hole."
ESO 495-21 is so incredibly far away that actually visiting it is not even imaginable at this point. It sits some 30 million light-years away, which means we're actually seeing what the galaxy looked like 30 million years ago, rather than its current state. Even though we were able to fast-forward to what the galaxy looks like in the present day, it would still be pretty young and is probably still building new stars with regularity
