Citizen Sky is a citizen science project providing you with a chance to do real scientific research. We are seeking to understand a star that has been a mystery to scientists for many years. This star is epsilon Aurigae, a very interesting, very bright star located in the constellation Auriga, the charioteer. This star is bright enough to be seen with the unaided eye even in the most light-polluted cities, and it is visible every fall, winter, and spring.
