What is the biggest universe?
The Milky Way is now known to be a member of Laniakea Supercluster, according to a new study. Caelum Supercluster contains approximately 550,000 galaxies. It’s the biggest galaxy supercluster of them all. Saraswati Supercluster is made up of 43 huge galaxy clusters, including Abell 2361, which contains about 2000 galaxies and is located some 1.5 billion light-years away from Earth.
Why do stars twinkle?
The light from a star is refracted and buffeted through the atmosphere by the air, bending it before you see it. Because the hot and cold layers of air continually move, the light’s bending changes as well, causing the star to wobble or glitter.
