The reporter learned from Tsinghua University on the 18th that international cooperative research led by Professor Li Yi's team, head of the Department of Astronomy at Tsinghua University, has identified 118 neutral hydrogen superbubbles in the Andromeda Galaxy using joint observations of the “China Sky Eye” and the US Carl Yonsky Very Large Array. Through direct observation, quantitative proof has been shown that continuous supernova eruptions in the star cluster are sufficient to maintain interstellar gas turbulence on a galactic scale. This is the first time in the world that has provided key empirical evidence for this scientific conjecture that has continued for decades. The relevant research results were published online in the latest issue of “Nature Astronomy”.
