Astronomers captured a stunning image of a black hole eruption in the galaxy Centaurus A. When seen from Earth, the ejection from Centaurus A presently expands eight degrees across the sky—the length of 16 full Moons laid next to each other. It was captured using the Murchison Widefield Array (MWA)…

Google Saturday's Google Doodle pays homage to the late Stephen Hawking, perhaps the most famous scientist of his time, who sought to explain the universe to millions. The renowned British theoretical physicist and cosmologist's work focused on increasing our understanding of black holes -- dying stars that've collapsed on themselves,…
