Star Clusters

The video explores star clusters, focusing on open and globular clusters. Open clusters are young, loosely bound groups of stars that eventually disperse. Globular clusters are older, denser, and contain hundreds of thousands of stars. They are among the first objects formed in the universe. The video also highlights famous clusters like the Pleiades and Hyades, and discusses the challenges of planet formation in globular clusters due to their lack of heavy elements.

What is the fate of open clusters over millions of years?

• They become globular clusters

• They evaporate

• They merge with galaxies

• They form new stars

What is the Pleiades known for?

• Being a globular cluster

• Being a binary star system

• Being a famous open cluster

• Being the closest star to Earth

What is a significant feature of globular clusters compared to open clusters?

• They are younger

• They are less dense

• They have a well-defined core

• They are irregularly shaped

How do blue stragglers form in globular clusters?

• By merging stars

• By exploding stars

• By forming from gas clouds

• By being ejected from the cluster
