Astronomers using NASA’s Spitzer Space telescope have found a likely solution to a centuries-old riddle of the night sky. Every 27 years, a bright star called Epsilon Aurigae fades over period of two years, then brightens back up again.

Description
English: Astronomers using NASA’s Spitzer Space telescope have found a likely solution to a centuries-old riddle of the night sky. Every 27 years, a bright star called Epsilon Aurigae fades over period of two years, then brightens back up again. Though amateur and professional astronomers have observed the system extensively, the nature of both the bright star and the companion object that periodically eclipses it have remained unclear. The companion is known to be surrounded by a dusty disk, as illustrated in this artist’s concept.
