Black Holes Galore

NASA’s Chandra observatory has with a recent observation, turned up several more black holes, than previously known, near the center of our closest galactical neighbor Andromeda. This survey has raised the number of known black holes there from 9 to 35.

One of the interesting findings, is that some are associated with globular clusters. Globs as they are appreciatively known by amateur astronomers, like yours truly, do not have that distinction in our own galaxy. At least as far as we know at this point in time, it is kind of difficult to observe your home galaxy in a detailed manner, due to the predicament of being located in said galaxy. Hard to get a distant perspective, plus the fact that all kinds of dust, and accumulated matter, make it difficult to peer inside our galaxy, making a thorough investigation difficult at best. The article goes on to explain that Andromeda’s central bulge is quite a bit bigger than our own, allowing more black holes to form. I doubt I will live long enough to see if there indeed is a chance of a glob in our galaxy sporting a black hole. It is the possibilities, and the desire to know, that keeps scientific investigation alive, and imaginations working overtime. (I think I am safe to assume, that not all of the existing globs in our galaxy have been discovered, or shown to not have a black hole. As always, I am open to evidence)

At any rate, I love to observe globular clusters, and galaxies when I’m cruising our galaxy on a moonless night, with my small yard cannon, a 12.5″ Newtonian telescope. Planets are fun too. Oh and planetary nebula’s, and double stars, and catching a stray meteor when I’m out there looking up, and supernova remnants, and open clusters, and stellar nursery’s, and yeah…I’m a geek.
