Above and Beyond: Star Cluster Pismis 24
This video shows a small cluster of stars, Pismus 24, with the brightest star, Pismus 24-1. It took high-resolution images from Hubble to show that Pismus 24-1 was really two stars orbiting each other.

A glowing red and orange nebula.
A glowing red and orange nebula.
Text, HUBBLE SPACE TELESCOPE. Pismis 24. In a nebula 8,000 light-years from Earth resides a small cluster of stars called Pismis 24.
A cluster of large bright stars above the nebula gas.
Text, The brightest star in this image is called Pismis 24-1.
It was once thought to be as massive as 200 to 300 suns.
A dotted line encircles the center, brightest star in the cluster.
Text, This would have made it the most massive star known in our galaxy.
However, high-resolution images from the Hubble Space Telescope reveal that Pismis 24-1 is actually two stars orbiting each other.
Each star is about a hundred times more massive than the Sun.
