Newest LIGO Signal Raises A Huge Question: Do Merging Black Holes Emit Light?

Billions of years ago, two black holes much more massive than the Sun — 31 and 19 solar masses each — merged together in a distant galaxy far across the Universe. On January 4th of this year, those gravitational waves, traveling through the Universe at the speed of light, finally reached Earth, …

Watch a 450-year-old supernova continue to bloom

Back in 1572, a white dwarf's explosion shone brightly on the sky. It was visible to the naked eye, and astronomers like Tycho Brahe were able to monitor the event despite not having the equipment we do today. We might have missed the chance to see what's now known as Tycho's supernova, but thanks …
