William's Telescope

At the time of William Herschel 's discoveries, astronomers were using Newtonian Reflecting telescopes.He improved the tech himself in 1789 by building the first 12 metre magnification reflecting telescope.

Uranus

Uranus is the seventh planet from the sun. It was discovered in March 13th, 1781. Herschel correctly identified it as a planet in 1781. It is believed that Uranus was knocked onto its side by planet-sized object as its axis is tilted 98 degrees, compared to Earths axis which is tilted at 23.5 degrees.


It is a gas giant with no solid surface. Its blue colour is from the tiny frozen ammonia crystals. Its atmosphere is mainly hydrogen and helium.

Mimas

Mimas is one of Saturns moons. He discovered it on the 17th of September, 1789. It is named after Greek mythology, Mimas. The surface area is less than that of Spain. It has a giant crater that is 130km wide, named Herschel after himself. The force of the impact that created this crater, sent shockwaves through the moon that created cracks on the opposite side of the moon.

Enceladus

Enceladus was discovered in 1789,the same year he discovered Mimas.Enceladus means 'Mythical Giant' in Greek origin.It's the sixth largest moon of Saturn.It is covered with water & ice that reflects most of the sun's light back into space.It has craters , ridges and smooth areas.


Enceladus has Cryrovolcanoes that fires out frozen water thousands of kilometres into space. The whole of E ring is believed to have been made from these ice particles. Because of the water near the surface, Enceladus may be one of the best places for humans to look for extraterrestrial life.

How He Influenced In Astronomy

William Herschel advanced our understanding of the nebulae in 1781. He also started the first study of stellar astronomy, which means the study of the region beyond our own solar system. Herschel also proposed a shape of our galaxy, which is very similar to what is known by modern astronomers hundreds of years earlier. His discoveries of Uranus, and its major moons and moons of Saturn also advanced our knowledge of the solar system
