On October 20, it was reported that an international team led by researcher Xu Cong of the National Astronomical Observatory of the Chinese Academy of Sciences had recently used the 500 meter aperture spherical radio telescope, known as the Chinese Celestial Eye, to image and observe the hydrogen atom gas in the famous compact galaxy group "Stephens Quintuple Galaxy" in the universe and the surrounding sky, and found a huge atomic gas system with a scale of about 2 million light-years, 20 times larger than the Milky Way where humans live.
