Young Stars are bursting with energy. During their early years, many stars will shoot streaming jets of plasma from both of its poles, and this plasma will collide with surrounding gas, creating a spectacular light show for telescopes back on Earth.
One such telescope, the Atacama Large Millimeter/sub-Millimeter Array (ALMA) in the high Atacama desert of northern Chile, recently captured one such star birth in unprecedented detail. Scientists working with soon-to-be-published data from the telescope released several beautiful images of this young star in action.
The excited gases surrounding the jets emanating from young stars are called Herbig-Haro Objects, and the image below shows one such striking example.
