Johannes Kepler s academic experience

Get to know Johannes Kepler in a minute.

Johannes Kepler (1571-1630) was a prominent German astronomer, physicist, and mathematician. Born in Württemberg, Wildersdadt, died in Regensburg. 1 Kepler discovered the three laws of planetary motion, namely the law of orbit, the law of area, and the law of period.

These three laws can be described as follows: all the planets orbit in elliptical orbits of different sizesIn the same time, the area swept by the planetary radial in the orbital plane is equal;The square of the planet's orbital period is proportional to the cube of its distance from the Sun. These three laws eventually earned him the nickname "Legislator of the Sky".

At the same time, he also made important contributions to optics and mathematics, and he was the founder of modern experimental optics. Johannes Kepler, the creator of the laws of planetary motion, was born in 1571 in the German town of Wildersdadt, exactly twenty-eight years after Copernicus published his Theory of the Movement of the Celestial Sphere. In this great work, Copernicus proposed the doctrine that planets orbit the sun rather than the earth.

Kepler studied at the University of Tübingen, where he received a bachelor's degree in 1588 and a master's degree three years later. Most scientists at the time rejected Copernicus' heliocentric theory. While studying at the University of Tübingen, he heard the logical elaboration of the heliocentric doctrine and quickly believed it.

On March 6, 2009, Eastern time, the Kepler space telescope, the world's first space telescope to detect terrestrial planets outside the solar system, was waiting to be launched at Cape Canaveral Air Force Base in the United States. At 22:50 on the same day, the rocket carrying the space telescope was successfully launched.

NASA launched the Kepler space telescope.

At 22:50 EST on March 6, 2009 (11:50 Beijing time on March 7), the Kepler Space Telescope, the world's first vehicle for detecting terrestrial planets outside the solar system, was launched from Cape Canaveral Air Force Base in the United States.

Kepler will be launched into space and may discover an extraterrestrial "Earth" within three years

NASA's Kepler satellite, scheduled to launch at 11:48 p.m. Beijing time on March 7, will open a new page in the search for extraterrestrial life. This item is ten.

The sixth- and seventeenth-century German astronomer Johannes Kepler's expedition will spend more than three years studying a group of stars, looking for faint periodic dimming in their brightness — signs that the star is surrounded by planets.
