六十年代在星际空间发现了比较复杂的星际分子,作为六十年代天文学四大发现而载入史册,七十年代已发现星际分子的数目与日俱增,到目前共发现60几种。随着星际分子不断发现,天文学开拓了“分子天文学”的新领域, In the 1960s, more complex interstellar molecules were found in interstellar space. As the four major discoveries of astronomy in the 1960s, they were recorded in the annals of history. In the 1970s, the number of interstellar molecules was found to have been increasing day by day.
