Thirty years ago today, on October 6, 1995 (leap August 12, 1995 in the lunar calendar), astronomers discovered the first planet outside the solar system. On October 6, 1995, two astronomers, MichelMayor and DidierQuéloz of the Geneva Observatory (UK) (UK), discovered the first extrasolar planet. Two Swiss astronomers announced today at the International Astronomical Conference in Florence that they have discovered a planet in the Milky Way galaxy. This is the first planet discovered outside the solar system, and it is regarded as the most significant astronomical discovery in recent decades. According to reports, the newly discovered star has a liquid structure, dark red, a volume equivalent to Jupiter (1,000 times that of the Earth), and only 10 to 20 light-years away from the Earth). It is located in the Pegasus constellation Star 51 Attachment, and revolves around Star 51 at an extremely fast speed for only 4 days. Because Pegasus 51 is not only similar to the sun, but also formed 3 billion years older than the sun, astronomers believe that there are probably other planets similar to the Earth around it. This further strengthens the hypothesis that life and civilization exist outside the solar system. The newly discovered star was "drowned" by the bright light around it. Currently, it cannot be seen through any of the existing astronomical telescopes in the world. Two Swiss astronomers discovered this planet after two years of observation, research and calculation of the stars around it. It is expected that by the year 2000, it can be seen through the first generation of astronomical telescopes.
