银河系中发现500光年宽的空洞

Astronomers have discovered an enormous cavity in the Milky Way galaxy that is believed to have formed after a stellar explosion millions of years ago. The bubble-shaped void is 500 light-years wide and is located between star-forming regions in the Perseus and Taurus constellations. The new finding may shed light on how supernovas generate star formation.
