Big Pic: A Violent Young Star
A violent young star ALMA (ESO/NAOJ/NRAO)/ESO/H. Arce. New imagery from the Altacama Large Millimeter/submillimeter Array and ESO's New Technology Telescope Like an especially unruly toddler, young stars tend to be violent. You can see one such example in new images taken by the Altacama Large Millimeter/submillimeter Array (ALMA)--the "largest astronomical project in existence"--and ESO's New Technology Telescope. According to a new study, this young star, Herbig-Haro 46/47, is about 1,400 light-years away from Earth. The images show the young star ejecting material at extraordinary velocities. "This system is similar to most isolated low mass stars during their formation and birth," Diego Madrones, a co-author of the study, says in a statement. "But it is also unusual because the outflow impacts the cloud directly on one side of the young star and escapes out of the cloud on the other. This makes it an excellent system for studying the impact of...
