A Giant Hole In A Midget Galaxy

Sifting through data from the Hubble Space Telescope, astronomers have detected the equivalent of a giant redwood, trapped in a block-size city park. They’ve found a monster black hole, five times as massive as the one at the center of the Milky Way, in a galaxy that’s 500 times smaller and 1,000 times lighter than our own.

And in that small space, relatively speaking, no wider than 300 light-years across, it squeezes in a whopping 140 million stars. So, if you lived in this dwarf galaxy and were to step out on the deck and gaze up at the night sky, you’d find it as dazzling as a Roman candle, lit up by one million stars. Our sky, as seen from our rooftops, looks wan in comparison, with a mere 4,000 stars.
