Even G1 contains a black hole! January 17, 2007Posted by dorigo in astronomy, Blogroll, internet, news, science.
Thanks to Kea for commenting a former post here, directing me to an article I had not read at int.stsci.edu. The article describes the ongoing searches for black holes in globular clusters of other galaxies.
Through it I got to know that the massive globular G1 in the Andromeda galaxy, 2 million light years away from us but still bright enough to be observable with amateur-sized instruments, contains a black hole weighing about 20,000 solar masses. G1 is the middle fuzzball in the green circle (the two other dots are foreground stars belonging to our galaxy).
Spectacular news! Especially since I did see G1 one month ago, see https://dorigo.wordpress.com/2006/12/15/my-first-andromeda-globular-cluster/ …
