Currently Research

This week, I produce newer mews about cosmos.

1.     the smallest planet in the history

A planet that the size is only 30% of earth had been discovered by space Kepler telescope and the news were presented in 21 Feb 2013. The telescope accurately senses the light and planets interfere the light from the fixed star which is the center of the system, then we can observe the planet by calculating the amount of decreasing light. We cannot observe cosmos directly because they are too far.

 In this far, saying what is good about this discovery, its observational accuracy is great. The first time of discovery of planets out of solar system was in 1995. When the telescope found size of planets was in 2000, from then it gradually become smaller that reach of we can observe taking 10years. In 2013, at length, we can observe the smaller planet than Mercury (the smallest planet in solar system)

2.     the mission of Curiosity

At 6 Aug. 2012, NASA launched Curiosity to Mars to research 4 studies.

First, the existence of life on Mars is.

Second, change of climate.

Third, the research of geology is.

Forth, ready to research by human.

The third may have little sense for you but it is very important. The one of important point is ground which water ran on. Now the Mars have little water but there is ground which seemed to be rivers. Easily speaking, ancient Mars have liquid water which means the environment of Mars was like the currently earth at that time. Curiosity have the system to analyze content of a rock and this system may let us know how the environment like the earth changed to current hard cold environment. Other interesting point is difference of south pole and north pole. The south pole is rocky and covered by countless quarter. On the other hand the north pole is relatively clean, no quarter. The difference means the north pole is newer than south one, but it isn`t known why the one is newer than the another. Curiosity may prove this question.

3.     The inflation of space

As I said sometimes in prior article, the space swells with acceleration. The first discoverer this fact is known as Edwin P. Hubble, an American researcher. However, in fact, there was faster discoverer in Belgium. Georges Lemaitle was. He must have honor and fame of this discovery. Why he didn`t? The reason is ironical. According to Nature (a scientific magazine, 10 Nov. 2011), Lemaitle released the discovery in 1927 at a minor magazine in French, it was the mistake. After 2years, Hubble released the discovery in English and it was known ordinary so that is thought the first article about inflation of space.

By the way, after more 2years, Lemaitle`s article translated in English was released and this could let us know the first discoverer was Lemaitle, but the article lacked the part of swelling space and the velocity. Lemaitle wrote the letter that says he erased the part by himself but some people say the letter was written by Hubble and he erased the part. If so, I and maybe you feel somehow shame to top scientists…

This is the last article in my blog. Great thanks for reading until now. See You until next meet!;)
