2024年12月23日 · Johannes Kepler, German astronomer who discovered three major laws of planetary motion. His discoveries turned Nicolaus Copernicus’s Sun-centered system into a dynamic universe, with the Sun actively pushing the planets around in noncircular orbits.

2018年10月30日 · After nine years in deep space collecting data that revealed our night sky to be filled with billions of hidden planets – more planets even than stars – NASA’s Kepler space telescope was retired. Kepler leaves a legacy of more than 2,600 planet discoveries from outside our solar system, many of which could be promising places for life.

2024年9月3日 · During its first six weeks of operation, Kepler discovered five exoplanets—named Kepler 4b, 5b, 6b, 7b and 8b (which NASA announced in January 2010). In April 2010, mission scientists published results that showed that Kepler had discovered the first confirmed planetary system with more than one planet transiting the same star, Kepler-9.

2004年10月6日 · Kepler used simple mathematics to formulate three laws of planetary motion. Kepler's First Law stated that planets move in elliptical paths around the Sun. He also discovered that planets move proportionally faster in their orbits when they are closer to the Sun; this became Kepler's Second Law.

2023年12月22日 · A biography of Johannes Kepler, from his troubled childhood to his mission to mathematically formalize Copernicus' heliocentric model by finding divine reasoning within the …

2023年8月30日 · Kepler was the first to present a coherent theory that the planets move around the Sun in elliptical orbits, that the speed of each planet varies, and that the Sun is responsible for that variation. Johannes Kepler was born on 27 December 1571 in Weil der Stadt in Baden-Württemberg, Germany.

By October 2018, and after nine years in deep space collecting data, Kepler had discovered more than 2,600 planets outside our solar system. Amongst the Kepler discoveries is Kepler-186f, the first validated Earth-size planet in the habitable zone of a star other than the Sun.

2024年3月5日 · Today, there are more than 5,500 confirmed exoplanets and over half of them were discovered from Kepler data. Many of these confirmed exoplanets reside in the so-called “habitable zone” of their star, making them prime candidates for future observations to uncover more of the universe’s mysteries, including the potential for life.

2024年7月13日 · Johannes Kepler is most remembered for his discovery of the three laws of planetary motion. Born in what is now Germany during the Renaissance, Kepler became both an astronomer and astrologer.
