Science Bulletins: Star Bolts from Crowded Nebula

4y ago


No star-forming region in our local Universe is as vigorous as 30 Doradus, also called the Tarantula Nebula. Now astronomers have used NASA's Hubble Space Telescope and ESO's 2.2-meter telescope at La Silla, Chile, to spot an outlier-a star destined to exit the nebula because of gravitational interactions among its throng of massive stars. This is the first direct observation of a stellar runaway in a dense, massive cluster.
