Young globular cluster NGC 1850 hosts two stellar generations, red giants, blue stars, and a black hole in Magellanic Cloud.

This Hubble image captures part of Caldwell 71, a loosely connected group of stars known as an open cluster

Thousands of stars shine in globular cluster Terzan 4, where hot blue stars cluster centrally and cooler red stars linger outward.

Colourful stars fill young globular cluster NGC 1805, where two stellar generations orbit tightly near the Large Magellanic Cloud’s edge

Thousands of stars shine in Liller 1, a 30,000 light-year distant cluster that began forming over 11 billion years ago

Some of our galaxy’s most massive, luminous stars burn 8,000 light-years away in the open cluster Trumpler 14.

Visible light reveals young stars piercing dense gas and dust in Trapezium Cluster, deep within Orion Nebula, 1,500 light-years away.
