Throughout the history, we, human beings have done many amazing things. I believe that every person would agree that those space discoveries were one of the most important and unbelievable for the humanity. There are too many of them but i will try to pick 5 of them, that are really interesting to write about.

Until 2005 a large number of scientists agree that, there are 9 planets in our solar system. With the discovery of a new planet called Eris, which was bigger than Pluto for 27 percent, everything has changed. Both planets, Pluto and Eris were now classified as dwarf planets. This caused losing of one planet in solar system. Since 2005, we’ve been having 8 planets.

There is another type of planet that we don’t know pretty much about them. These planets are called Exoplanets. Exoplanets are planets that orbit in a different solar system than where we are now.Earlier in 2015 scientists discovered the exoplanet called Kepler-452b. Because of its similarities with the earth, scientists called this planet Earth’s cousin.

Since humans have been discovering our solar system and all space bodies, the ones that are most unknown to us are black holes. The reason why we are not so familiar with them is because, it was really hard for scientists to develop further researching on them without. After launching super strong Hubble telescope into space, which was designed to send clearest pictures back to the earth, scientists were finally able to give us more information about black holes. Black holes are believed to be dying stars that collapse inward from their own weight. Their gravity force is so strong that even light can’t escape. That’s why they are black.

Since Mars is one of the closest space body around us, we have spent a lot of time doing researches on it. The one that was most important for us was exploring Mars for the first time when we got pictures in color of Mars. It was also an experiment to go and check if the life would be possible on Mars. Later, we continued with researching this planet and another amazing discovery has happened. Scientists claim that they discovered there is liquid water on that planet. This proves that life could exist somewhere far away from us.

The last one that happened recently was, the first landing on a comet in 2014. This one was important because it finally allowed scientists to study the material that make up a comet for the first time. I think that it would be really an amazing thing if one day we would find some other living species far away from our home. It would be unbelievable to share our history with some species that we didn’t even know exists.

FUTURE RESEARCH QUESTION: The moon..
