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]

The Mystery of a Super-Fast Spinning Supermassive Black Hole

  Two X-ray space observatories, NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) and the European Space Agency’s XMM-Newton, have teamed up to measure definitively, for the first time, the spin rate of a black hole with a mass 2 million times that of our Sun.  This artist’s concept illustrates a supermassive black hole with millions to [continue reading]
