From Being Visual: This Crab Nebula is a remnant of a star’s supernova explosion. It’s six light-years wide and expanding! Congratulations to the three astrophysicists who won this year’s Nobel Prize in physics for discovering that the fading lights of supernovas tell us that our universe is expanding into a cold, dark place.
