Actually the terms "Globular" and "Open" are not related to the number but the age of the stars. Globlular clusters are many old stars packed in spherical form (they look like hazy mothballs to the naked eye) and "open clusters" are many young stars formed close to each other. The constellation Pleiades is an example of open cluster.
Actually, a supercluster can contain millions to billions of stars, along with gas, dust, and dark matter. Superclusters are some of the largest known structures in the universe, made up of numerous galaxies and galaxy clusters bound together by gravity. They can span hundreds of millions of light-years.
False. A concave lens usually produces virtual images. Concave lenses cause light rays to diverge, so the image formed is located behind the lens and cannot be projected onto a screen.
That is false.
False
It is false.
False. A quasar is not a type of globular cluster. Quasars are extremely energetic and remote celestial objects powered by supermassive black holes, while globular clusters are tightly bound groups of stars that orbit galaxies.
