Mathematical calculations to explain an anomaly in the orbit of Uranus. predicted it existence before it was seen.
Neptune and Pluto are not the same discovery at all.
it was unknown until they found a gravitational pull on Neptune
The planet Neptune has not completed a full orbit since its discovery in 1846. It takes Neptune approximately 165 Earth years to complete one orbit around the Sun, so it has only completed a fraction of its first orbit since its discovery.
It isn't. Neptune's blue color is due to the presence of methane.
Uranus and Neptune appear blue due to methane gasses. Earth is also mostly blue due to vast oceans.
Neptune and Pluto are not the same discovery at all.

It was because of anomalies un Uranus' orbit that Neptune was discovered.

No. Neptune is blue, due to methane gasses.

The discovery of the cell was possible due to the invention of the microscope.

Edwin Hubble did not discover Neptune. Galileo's drawings show that he first observed Neptune on December 28, 1612, and again on January 27, 1613. On both occasions, Galileo mistook Neptune for a fixed star when it appeared very close in conjunction to Jupiter in the night sky, hence, he is not credited with Neptune's discovery. Neptune was discovered due to the anomalies it caused i Uranus' orbit. There is a small dispute over who discovered Neptune. An international consensus emerged that two astronomers, Urbain Le Verrier and John Couch Adams, jointly deserved credit. See the link for more information. The law of Gravitation predicted the existence of planets beyond Uranus Observations in the orbit of Uranus led to the discovery of planet Neptune. It was discovered in the nineteenth century.
