The Springfield Observatory came to prominence when it was alerted to a comet (discovered by and named for Bart) hurtling towards Springfield. After the disaster was averted, Moe and a large group of survivors decided to burn down the observatory, so that "This'll never happen again!"
The observatory is seen again, in the tenancy of Professor Frink, who was afraid to leave in case another group of scientist attempted to move in during his absence. It stands on a hill near the Squidport.
