An international team of astronomers has discovered a massive galaxy that consists of 99.99 percent dark matter. Even though it is relatively nearby, astronomers had missed the galaxy, named Dragonfly 44, for decades because it is very dim. The galaxy lies about 300 million light-years away in the constellation Coma.
A new Gemini Observatory image reveals the remarkable “fireworks” that accompany the birth of stars. The picture captures in unprecedented clarity the fascinating structures of a gas jet complex emanating from a stellar nursery at supersonic speeds. Researchers believe they have also found a collection of runaway (orphan) stars that result from all this activity.
