Messier Monday: The Teapot-Dome Cluster, M28

"A collection of eight stars stands out in this region of the sky, not because they’re the brightest stars around, but because they have a distinctive pattern to them that we recognize as very similar to a common object here on Earth. We call such a collection of stars an asterism, and the teapot is one of the most recognizable ones. And the star at the very top of the teapot’s lid — Kaus Borealis — has a secret less than a single degree away from it."
