Famous Astronomers- Galileo Galilei
Galileo Galilei was born on the 15th of February 1564 and died on the 8th of January 1642 aged 77.
He was born in Pisa. He had 6 siblings and his father was Vincenzo Galilei.
He made improvements to the telescope and discovered Jupiter's biggest moons,named the Galilean moons. He observed sun spots and analysed them. He also made improvement to many other instruments like the military compass. He also believed that the planets revolved around sun.
He stood up to the church in 1615 with the fact that the planets revolved around the sun, not Earth, but was convicted with heresy and got placed under house arrest for the rest of his life. Where he died.
Well that's it, tomorrow will be Stephen Hawkin. So tune in tomorrow.

famous astronomers- Edward Hubble
O.k, i know I've been awhile, i was just planning and researching.
Well I thought I'd start with legends, so Edward Hubble was the one to choose first!
So, Edward Powell Hubble was born on the 20th of November 1889 in Marshfield, Missouri, U.S. He died on the 28th of September 1953 aged 63 years old. His mother was Virginia lee James and his father was John Powell Hubble. He had two sisters and two brothers. At university he studied law, but took courses in science and maths. His wife was called Grace Burke, they got married on the 26th of February 1924.
His most important discovery happened in the 1920's when he looked through the most powerful telescope of the time. He saw faint patches of light and thought that there were more galaxies, proving that the universe went past the milky way galaxy!
The Hubble telescope was launched in 1990 and was made in honor of Edward Hubble. It is planned to be disbanded in 2014, but could last until 2020. Its successor will be the James Webb Space Telescope and will be launched in 2018.
I will be doing Galileo Galilei next! Sorry again I was away for a while, and have been before, but I've been concentrating on school.
So see you! ;)

Dwarf planets
First, thank you for three hundred page views, i never thought I'd be here, I know its not much but it means a lot to me. Anyway, without further ado, lets begin!
Dwarf planets are planets with a maximum of 500 km and an unclear orbit. There are four in our solar system, Pluto, Makemake, Eris and Ceres. Ceres is in the Asteroid belt and the rest are in the Oort cloud or the Keiper belt.

Neptune
The final planet in the system. It has 13 moons and quite big rings. One of neptune's moons, titan, will crash into neptune and make rings for saturn to contend with. It takes 164 years to travel round the sun and it has an atmosphere of methane, hydrogen and helium. One day on neptune is 16 hours.
Well thats it, bye!
