They're shy
In 1952, three stars captured in a photographic plate vanished within an hour, leaving astronomers puzzled. The stars likely dimmed by a factor of 10,000 or more, raising questions about the cause of their sudden disappearance. Possible explanations include gravitational lensing, Oort Cloud objects, or contamination from nuclear weapons testing.
