Man first discovered water on a livable planet. Are you ready to emigrate?

On September 1 1, Nature Astronomy published the latest research results of a group of astronomers from University College London (UCL). They found signs of water vapor on a planet named K2- 18b. As the first super earth with known water and located in the livable zone, what do these eye-catching keywords mean? The crystallization of the two space telescopes and the rapid development of modern astronomy are inseparable from the contributions of the telescopes.

4 10 years ago, Galileo aimed his telescope at the starry sky for the first time and saw the universe farther and deeper. Since then, astronomers have been able to spy on more mysteries of the universe that cannot be touched by the naked eye. This discovery is also based on the data of two great space telescopes, which can be said to be the crystallization of their achievements. Kepler mission is one of them. It is the telescope that has found the largest number of exoplanets at present. Of the more than 4,000 confirmed exoplanets,

Kepler himself contributed more than half. The name of the exoplanet K2- 18b comes from the K2 project in the later period of Kepler telescope. It first discovered the exoplanet K2- 18b in Leo in 20 15, which was later confirmed by the ground telescope. K2- 18b is located in the potential livable zone and has a strong "signal", so it has attracted the special attention of many astronomers.

If Kepler's contribution is the discovery of K2- 18b in the vast Xinghai, then another famous Hubble Space Telescope provides key data support for detecting water vapor in its atmosphere. Hubble's Wide-field Camera (WFC) can photograph celestial spectra in infrared band.
