- The Milky way
- The Andromeda galaxy
Laniakea Supercluster Facts : it contains local group clusters like the one in which Milky way exists!
- The size of the observable Universe is 1026. Measured in light-years, it comes out to be 46 billion light years.
- According to the theory of expansion , it keeps on expanding, and this value keeps on changing over time.
The Universe Circle Fact : Distance between Earth and Sun : 150 million kilometers.
This is just the description of the Universe that can be observed by us using the given technology.
This is how tiny we are that we cannot be depicted graphically on the same plane! Tiny, yet capable of doing great things!
