Just a bit of news from Backyard Stargazer Central – this blog is now featured in the Alltop directory of Astronomy blogs.
There’s an ever-growing community of great blogs and online news sources covering every aspect of space sciences and exploration and I’m proud to be a part of it.

If it’s hard to wrap your mind around the concept of black holes, watch this video. Star S2, the closest star to the center of the Milky Way, gets whipped around by … something.
S2 takes 15 years to orbit around the super-massive black hole at the center of our home galaxy. At its closest, it gets within one light day – about twice the size of the orbit of Neptune – of the black hole. The black hole – designated Sagittarius A* – is believed to be more than 3.7 million solar masses in mass.
