The Double Cluster (NGC 869 and NGC 884, also known as h and χ Persei) is a visually striking pair of star clusters visible to the naked eye, documented since at least 130 BC. Located approximately ...

This one-million-year-old star-forming region contains thousands of new stars and hundreds of planetary mass objects floating freely in the nebula, not orbiting stars. A groundbreaking study published ...

For generations, astronomers have pondered the origins of globular clusters, which are among the universe’s oldest and ...

Simulations have revealed the pathways for the formation of globular clusters. The simulations have also revealed the potential formation of an entirely new class of objects.
