History of Impossible Astronaut Day
On April 23, 2011, the first episode of the sixth season of the series “Doctor Who” aired on television, called “The Impossible Astronaut”. This sci-fi series appeared for the first time on television in 1963.
The show has attracted fans from different generations and it follows the adventures of the Doctor, who is a time-traveling ‘alien.’ The Doctor travels through time and space in a time machine that is also a spacecraft, called the Tardis. The Tardis looks like an inconspicuous London police box from the 1960s.
The episode “The Impossible Astronaut” quickly became one of the most-watched and appreciated episodes of the series. New alien monsters, called the Silence, were introduced in this episode. The characters were not able to remember that they had seen the alien monsters once they took their eyes away from them. To remind themselves that they have seen the monsters, the characters started putting tally marks on their skin.
To celebrate this day, all the Whovians draw tally marks on their skin or parts of their body. As an inside joke, the fans act normal and pretend that they are unaware of why the tally marks are there.
