Globular star clusters hold key to life in space: Scientists
Q. What are globular star clusters?- Published on 08 Jan 16a. Clusters holding million stars in the ball
b. Clusters holding planets and stars in a ball
c. Both a and b
d. Neither a nor b
ANSWER: Both a and b
A globular cluster holding million stars in a ball about 100 light years ago could be the place to look for intelligent life identified in the galaxy. Milky Way galaxy hosts about 150 globular clusters, most of them orbiting in the galactic outskirts. They formed about 10 billion years ago on average, researchers said. Some scientists have argued that this makes globular cluster stars less likely to host planets. In fact, only one planet has been found in a globular cluster to date. Interstellar communication becomes easy for stars within the cluster called global customer opportunity.
