A Close Look at Drama of Starbirth

  Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have obtained a vivid close-up view of material streaming away from a new-born star. By looking at the glow coming from carbon monoxide molecules in an object called Herbig-Haro 46-47 they have discovered that its jets are even more energetic than previously thought. The very detailed [continue reading]
