A discovery made by a group of scientists from the Nordic Institute for Theoretical Physics in Sweden and was led by Beatriz Villarroel shows that 100 stars have disappeared from space in the past 70 years.
They compared star maps from the 1950s to those today. After analyzing the old and new surveys, scientists are convinced that at least 100 stars that were previously listed are no longer be seen in space; they simply vanished.
100 Stars Vanished From Space
The project is part of the Vanishing and Appearing Sources during a Century of Observations (VASCO), which scan the sky for objects that have physically disappeared from (or appeared on) the sky during the last decades. The final goal of the project is to identify unusual astrophysical targets for follow-up analysis with extreme, exotic, or bizarre patterns of variability.
The main question is: where could the missing stars be? This event is one of the astrophysical mysteries raising lots of other big question signs. At the moment, researchers have two possible reasons for the main question.
The first reason could be that the stars are in the same location, just not emitting light, they’re undetectable. The second reason could be that the stars have changed their positions. This bizarre event has to be investigated further and in more depth to be understood.
One explanation is that the stars listed in the old surveys were other astrophysical events that are stars look alike. For example, flaring dwarf planets or failed supernovas are similar to stars.
Another explanation is that black holes might have eaten the stars, however, though these reasons might have worked for a smaller number of missing stars. Last but not least, a possible theory could be that these 100 stars were relics of “technologically advanced civilizations,” hence of alien life. We hope to find out more about this intriguing space enigma soon.
