This 18 February 2020 video says about itself:
Betelgeuse May Explode Anytime!
Betelgeuse is a red supergiant star located 650 light-years away from Earth. At the end of the year 2019, astronomers noticed that Betelgeuse is dimming.
Recent high-resolution images show that Betelgeuse is going through some changes. It is fading and changing its shape instead of round, it appears squashed into an oval.
Some astronomers also suspect that Betelgeuse has exploded already in the past but since it’s 650 light-years away from us, light will take 650 years to reach Earth.
