"We might be witnessing the final stages of the formation process of our galaxy, " says W. Butler Burton, radio astronomer. A giant cloud of hydrogen gas, clocked at more than 150 miles per second per second, is closing in very fast on the Milky Way, likely setting off a huge burst of star formation. At its current speed, the cloud will collide with interstellar gas in the Milky Way's disk in less than 40 million years, condensing into tens of thousands of bright, massive stars that will explode as supernovas within a couple of million years.
