The globular cluster M4 is a grand spectacle by almost any measure. Like any cluster of this kind, it contains more than 100,000 suns that all orbit each other. However M4 is notable because it has a number of things that stand out ("ests") beyond its staggering number of stars. It is one of the closest globular clusters to us which enabled astronomers to detect white dwarfs (remnants of prior suns) in their midst. These white dwarfs are some of the oldest stars in our galaxy still shining after 13 billion years. In addition the cluster even contains pulsars- one of which appears to have a planet orbiting it.
