Like all the rest of the universe, galaxies are born, live and eventually die. With incredibly powerful tools like the Hubble Space Telescope, we can see different galaxies at almost every stage of their lives.
One of his latest observations was published on the Hubble website and presents the starburst galaxy ESO 495-21. His name may lack personality, but he largely compensates with a violent heart that quickly pumps new stars. The galaxy is full of big stars all quite young and shows no signs of slowing down.
As the Hubble story explains, the galaxy is overflowing with what scientists call clusters of super stars or areas of extremely high star density. The massive stars of these regions are quite young by the galactic standards – some millions of years or so – and this offers Hubble researchers the opportunity to study star formation in the emerging galaxy.
As for the center, the scientists have a very good idea. "In addition to hosting cosmic fireworks that are star clusters, ESO 495-21 can also house a supermassive black hole in its center," Hubble Group says. . "Astronomers know that almost all large galaxies harbor such an object in its center and, in general, the larger the galaxy, the larger the black hole is."
ESO 495-21 is so incredibly remote that it's not even imaginable to visit it at this point. He sits about 30 million At light-years away, we see what the galaxy looked like 30 million years ago, rather than its current state. Even if we could move quickly to what the galaxy looks like today, it would still be pretty young and would probably build new stars with regularity.
