Scientists always amaze us with their latest discoveries, and when it comes to space, there are always new things to learn. Let’s see what we found out this week.
Astronomers are witnessing the death of the Small Magellanic Cloud, which is a dwarf galaxy. It appears that the galaxy does not have power to form starts any longer. “Galaxies that stop forming stars gradually fade away into oblivion. It’s sort of a slow death for a galaxy if it loses all of its gas,” said Naomi McClure-Griffiths of The Australian National University’s Research School of Astronomy and Astrophysics. It is believed that the Milky Way will eat this galaxy.
Galaxies merged together
Scientists were able to witness something unique recently. They finally have proof that black holes merge. Astronomers observed various galaxies unite in the form of a huge black hole. You can see images of it take by the optics system of the W.M. Keck Observatory.
“Seeing the pairs of merging galaxy nuclei associated with these huge black holes so close together was pretty amazing,” said Michael Koss, a research scientist at Eureka Scientific. “In our study, we see two galaxy nuclei right when the images were taken. You can’t argue with it; it’s a very ‘clean’ result, which doesn’t rely on interpretation.”
The fountain-like black hole
A black hole discovered at the center of the Abell 2597 galaxy amazes us with its fountain like movements. Cold molecular gas falls into the black hole and then jets of it are sprayed back out.
“Galaxy evolution can be pretty chaotic, and big galaxies like this tend to live hard and die young.For the first time we have been able to observe the full cycle of a supermassive black hole fountain, that acts to regulate this process, prolonging the life of galaxies,” declared Timothy Davis of Cardiff University’s School of Physics and Astronomy.
