Cosmic Cloud Poised to Birth Massive Star A massive, tranquil object found lurking in a dark cloud in our galaxy could be about to transform into a massive star or stars, giving astronomers their first glimpse at such a region on the cusp of stellar birth. The cloud, located near the Aquila rift in the galactic plane 23,000 light-years away, has a mass 120 times that of the sun, but it is all compressed into a volume smaller than the Oort cloud of comets orbiting our solar system, astronomers said here today at the 214th meeting of the American Astronomical Society.
