The red giant Aldebaran dominates the skies near the star's massive companion. As the dying star sheds dust and gas, some of this material is trapped by the companion's gravity, settling into a tenuous dark ring. Below us and in the foreground, one of the companion's moons, it's rocky surface melted by stellar outbursts, broils in the scorching heat of the giant star. If Aldebaran replaced the sun in our own solar system, its surface would extend halfway to the orbit of Mercury.
