I went to Bandung to get more knowledge about earth plates and solar system. First, I went to Bosccha. There, i saw a the a telescope and it’s the biggest telescope in south east asia. People cannot use the telescope at day because it might bother the health of people’s eyes. The plan for this place about to make is around in 1920. Which is when mr.bosscha and his friends making an organization. In 1923 this place was created until 1928. This place named Bosscha because that time, Bosscha was the person who gave a lot of money for this place or we can call invention.

Bosccha picked the place in Lembang because Lembang was a place that is not crouded yet. It’s a good place because if it’s too corouded, it can bother the sight seeing from the telescope. There are also onother telescope in Bosscha. They are GAO-ITB, Coto, Unitron, Coronado, Foleostat, Bamberg and many else. One of them, can be use to hear the sound of what’s going on out there. On of them also a telescope that can be use at day or sun.

Instead of knowing the telescope, I aslo got knowledge about solar system. One of them is about why pluto is not considered as a planet anymore? So it’s because pluto have thousands friends or planets that is simillar with pluto and pluto was found that this planet had a different orbit with other planets. In 2006, finally pluto is not considered as a planet anymore. Then, i also learned about stars, diameter and distance. The distance between earth and sun is about 150.000.000 km. The diameter of sun is 1.400.000 km. The diameter of earth is 12,714 km and 3,472 for the moon diameter. Sometimes, stars were bigger than the sun. Even the biggest telescope cannot catch the full size of the stars or any object in the space.

Second place, i went to Museum Geology. There, i learned about earth plates, solar system and a little bit about fossils. The Nebua Theory is a theory that formed our solar system. Indonesia was invented by the last centuries because of the continential plate. There is subduction zone from parit sumatra until java. In Indonesia, there are alot of coal which is in sumatra.

I also learn about volcano. So it was formed because of the oceanic crst and the continential plate meets. The thing that makes it erupt is because of a strong pressure that can make the volcano erupt. The magma, sand and gasses will come out from the volcano. The lava will go on by rain and become lahar. The sand can be the natural resiuces and the ground will having a good quality.

Then, i learned how does mount everest formed. So, india had been crashed with Asia. There is a strong power from the accident until it can formed the mount everest. The first climber of mount everest is George in 1924. The everest is located near the see. However, it never get wet.
