Betelgeuse is a massive red supergiant star located in the constellation of Orion. It is one of the brightest stars in the night sky and is easily recognizable due to its reddish hue. Betelgeuse is about 700 light-years away from Earth and is known for its size; if it were placed in our solar system, it would extend beyond the orbit of Mars. This star is nearing the end of its life cycle and is expected to explode as a supernova in the future. When this happens, it will be an incredible sight, potentially visible even during the day. Scientists study Betelgeuse to learn more about stellar evolution and the life cycles of stars.
