From the 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.”
