Three stars are connected in a line with a symmetrical prism on each side. What star is it?

Congratulations, I saw Orion, the most spectacular constellation in winter.

This constellation is also the first one I know for the first time. There is Betelgeuse, and besides the seventh bright sun, there is Betelgeuse all day, which looks a little red and serious. This star is also the star that scientists say will erupt recently. If it really erupts, its brightness will suddenly increase by hundreds of thousands of times, and we can see another sun.

I hope it helps you.
