Hubble Captures Messier 54: A Globular Cluster
Imagine a beautiful ball of stars, like a giant cosmic snowball.
This is a globular cluster, and the Hubble Space Telescope took a picture of one called Messier 54.
What makes Messier 54 special is that it was the first one ever found outside of our own galaxy!
It lives in a smaller galaxy, a dwarf one, that's like a tiny friend of our Milky Way galaxy.
This cluster was first spotted a long time ago, in 1778, by a person named Charles Messier.
