Explanation: 

Detailed explanation-1: -Constellations are clusters or groups of stars that appear to form recognisable shapes or patterns in the night sky. There are 88 modern constellations.

Detailed explanation-2: -Galaxies are thought to begin as small clouds of stars and dust swirling through space. As other clouds get close, gravity sends these objects careening into one another and knits them into larger spinning packs.

Detailed explanation-3: -A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems. A galaxy is held together by gravity. Our galaxy, the Milky Way, also has a supermassive black hole in the middle. When you look up at stars in the night sky, you’re seeing other stars in the Milky Way.

Detailed explanation-4: -Small groups of stars are called star systems, and somewhat larger groups are called star clusters. There are even larger groups of stars, called galaxies. Our solar system is in the Milky Way Galaxy, which is just one galaxy in the universe.
