We hope you’re having a Stellar Saturday! ?

A glimpse from the @NASAHubble Space Telescope reveals an ancient, glimmering ball of stars. This globular cluster of stars moves slowly through space on the outskirts of the Large Magellanic Cloud, one of our closest galactic neighbors.
This cluster is certainly one for extremes. It has a mass equivalent to roughly 140,000 Suns and and an age of around 13.1 billion years — making it almost as old as the universe itself.
The stars in this cluster are not only dazzling — they are also indispensable tools. Some of these particular stars have well-defined luminosities, meaning that astronomers know the total amount of energy they emit. By comparing star luminosities, we can calculate the distances to these stars!
