A New Black Hole?

Supernova remnant W49B is not your run-of-the-mill remains of an exploded star. In most cases when a star explodes, its cosmic guts scatter equally in all directions, forming a ring of material around the blast site. But W49B looks different. By combining X-ray images from NASA's Chandra X-ray Observatory, radio data from NSF's Very Large Array, and infrared images from Caltech's Palomar Observatory, scientists were able to create a detailed picture of the supernova remnant. By examining the image they found that not only did an unusual explosion produce W49B, giving it a barrel-shaped appearance, but it also lacked a neutron star at its center—a common feature of supernova remnants. Scientists think in place of the neutron star there may lie a black hole. If this is true, it means that W49B could harbor the youngest black hole ever detected in the Milky Way galaxy.
