Aldebaran

The angry red eye of Taurus the Bull/Stars

Aldebaran is an orange giant star that forms the glaring eye of the constellation Taurus. Despite being only about 1.16 times the mass of the Sun, it has swollen to roughly 44 times the Sun's diameter as it exhausts its hydrogen fuel. It shines with a warm orange glow that has made it one of the most recognizable stars in the night sky for thousands of years.
