The star Betelgeuse is a red supergiant at the distance of 600 light years from Earth. It is expected to go supernova roughly within the next 100’000 years. However in 2019-20 Betelgeuse temporarily lost more than half of its brightness, which caused some speculations that it might go supernova sooner, potentially this century.

The market resolves positively as soon as the light of Betelgeuse supernova reaches Earth.

I do not bet on my own questions.
