HE-0450-2958

Posted on Updated on


It has been some time since I wrote about anything on my blog, primarily because of a series of events in my life. Unfortunately south parts of Sweden have been covered completely by clouds during a long period of time. The weather became much better during Christmas holidays but unfortunately there was so little time left for observing after spending time with family and friends.

Regardless, there are some discoveries and news that came in focus for the astronomy world. Such as the sunspot activity which get increased for every week. Sunspot 1040, which was barely visible at the beggining, but now it seems to get increased both in size and activity.

A new debate started between a group of French and German astronomers regarding supermassive black holes. It came to the attention after lengty observations that there is a group of black holes responsible in the creation and formation of new stars within galaxies thank to their powerful jet streams of materia ejected by them out in the space.
The question though is, which one came first during the early stages of the universe? Was it a supermassive black hole or a galaxy? As known already to us, a supermassive black holes exist in the center of galaxies but there are some supermassive black holes that are “naked” or “without home”. Those black holes roam the universe alone, such as the quasar HE-0450-2958. There are some that oppose the idea by answering that galaxies were first to exist.
It is interesting to see what conclusion will be drawn by scientists in the future.

Finally, I wish to you all a happy new year!
