As we broadcast, the Voyager 1 spacecraft, launched from earth in 1977, is approximately 10.8 billion miles away and has only just left the outer influence of the solar system. Meanwhile, the Large Magellanic Cloud, the closest large galaxy to our home galaxy, the Milky Way, is a mind-boggling 89 million times further away — 163 million light years. Given such daunting distances, even science fiction writers hesitate to postulate space travel between galaxies.
Yet, a new study from Northwestern University suggests that we are all, in a sense, intergalactic travelers. Daniel Angles-Alcazar a post-doctorate fellow at the Center for Interdisciplinary Exploration and Research in Astrophysics, is the primary author of the study, and he joins Eight O’Clock Buzz host Brian Standing, by phone.
