The Webu Telescope found the evidence of the outer planet atmosphere containing carbon dioxide for the first time

Xinhua News Agency, Beijing, August 26. The National Aerospace Agency (hereinafter referred to as the US Astronaut) said on the 25th that the James Weiban Space Telescope first found clear evidence of the existence of carbon dioxide in the atmosphere of the outer planet. Although the planet is a gaseous planet, the above discovery brings hope for researchers to find similar ingredients in solid -state planets that are more suitable for life. The international academic journal "Nature" is about to publish related research results.

According to the U.S. Aerospace Administration, the planet is called WASP-39 B, about 700 light years from the earth, about a quarter of Jupiter, 1.3 times the diameter of Jupiter, and the surface temperature is about 900 degrees Celsius. Unlike the solar gaseous planet, the running track of this planet is very close to the stars around it, about one -eighth of the distance between the sun and Mercury, and turn around for a week in the four more days of the earth.

The first report of scientists in 2011 found the planet, and the previous observations showed that water vapor, sodium and potassium had water vapor, sodium and potassium in its atmosphere. When it passes by itself from the stars that revolt around, it will block some light from this star. There are also some light of the star through the edge of the planet through its atmosphere, and the near -infrared spectrometer carried by the Weibu Telescope can be able to It was detected that the subtle changes in the atmosphere of the planet to help scientists determine its atmospheric components. The atmosphere of WASP-39 B planet is thick, and from the location of the Wabbu telescope, the planet can frequently pass through the star. Therefore, this planet has become the ideal object of the Weibu telescope to test its near-infrared spectrometer.

Understanding the atmospheric composition of planets is essential for studying the origin and evolution of planets. Mike Lean, a researcher at Arizona University, who participated in this research, said that carbon dioxide molecules are "sensitive tracers" in the process of planet formation. How much solid and gaseous substances. " In the next 10 years, the Weibu telescope "will be launched on multiple planets" in order to understand how the planets formed and analyze the uniqueness of the solar system.

Speaking of the new discoveries of the Webb Mirror, Piel Olivier Paradit heating told AFP: "For me, it is a huge-class planet or and and and and with a heating of celestial physics The planet with similar size of the earth opened a door. "

The Wabu telescope was jointly developed by the United States Aerospace Administration, the European Space Agency and the Canadian Astronautics Agency, and was regarded as the "successor" of the Hubble Space Telescope. It launched a launch from French Guyan Cuuru Space Center on December 25, 2021. On January 24 this year, it successfully entered the running track around the second Laglang day point around the Japanese and ground system. How the first galaxy was born in the previous universe, studying the various stages of galaxy evolution, and observing the formation of stars and planetary systems.
