Astronomers compared old and new astronomical photographs and found that at least a hundred stars had disappeared or been hidden. Scientists believe that many places where stars disappear can be used as ideal places to search for alien civilizations. On March 16, 1950, astronomers at the U.S. Naval Observatory (USNO) took a photo of the telescope in the direction of Sirius, and today’s photos of the same location reveal the missing, possibly evidence of what is lurking here.
Back in 2016, Swedish researchers reported unable to find a star in the USNO photo. They conducted a follow-up investigation and found that another 100 stars were missing compared to the old and new astronomical photographs.
They report in the journal Independent Journal that unless a star collapses directly into a black hole, there is no known physical process to explain its disappearance. They believe that these disappearing objects could be used to search for clues to advanced civilizations.
