Imagine living in a world where, every 69 years, the sun disappears in a near total eclipse that lasts for three and a half years. That is just what happens in an unnamed binary star system nearly 10,000 light years from the Earth. Astronomers have discovered an unnamed pair of stars that sets a new record for both the longest duration stellar eclipse (3.5 years) and longest period between eclipses (69 years) in a binary system.
