With the dawn of 2015, there’s been a lot of references to the Back to the Future series. The original movie is now as far into the past as 1955 was for the original movie, and 2015 marked “the future” for the series. But despite the jokes, one could argue that in fact we are living in the future. At least as far as astronomy and astrophysics goes, we’ve come a long, long way in the past 30 years.
