Astronomy Picture of the Day - Globular Cluster Omega Centauri

Explanation: Globular star cluster Omega Centauri packs about 10 million stars much older than the Sun into a volume some 150 light-years in diameter. Also known as NGC 5139, at a distance of 15,000 light-years it's the largest and brightest of 200 or so known globular clusters that roam the halo of our Milky Way galaxy. Though most star clusters consist of stars with the same age and composition, the enigmatic Omega Cen exhibits the presence of different stellar populations with a spread of ages and chemical abundances. In fact, Omega Cen may be the remnant core of a small galaxy merging with the Milky Way. With a yellowish hue, Omega Centauri's red giant stars are easy to pick out in this sharp telescopic view. A two-decade-long exploration of the dense star cluster with the Hubble Space Telescope has revealed evidence for a massive black hole near the center of Omega Centauri.

Imagine what the night sky would look like if you lived in the center of that thing.

Imagine the night sky from a planet in that cluster.

Nice! Both sets of patterns are produced by the expansion of gas propelling matter.

You would not want to be at the center. There is a massive Black Hole there keeping it all together.

my first thoughts on it, looks like paint splattered on canvas and some one used an pencil eraser in the center.

I had a globular cluster one time. Doc said it was the worst one he’d ever seen.
