People Watching at Astoria Park Hills

Our Hubble Space Telescope finds big surprise in teeny tiny galaxy: A supermassive black hole with a mass 21 million times our sun. The black hole is five times the mass of the one at the center of our Milky Way galaxy. It is inside one of the densest galaxies known to date -- the M60-UCD1 dwarf galaxy that crams 140 million stars within a diameter of about 300 light-years, which is only 1/500th of our galaxy’s diameter. If you lived inside this dwarf galaxy, the night sky would dazzle with at least 1 million stars visible to the naked eye. Our nighttime sky as seen from Earth’s surface shows 4,000 stars. This is an artist's view of M60-UCD1 black hole. Image Credit: NASA, ESA, STScI-RCC14-41a #nasa #space #galaxy #milkyway #blackhole #astronomy #stars #hubble #hst #telescope #science
