Pulsar encased in supernova bubble
Massive stars end their lives with a bang: exploding as spectacular supernovas, they release huge amounts of mass and energy into space. These explosions sweep up any surrounding material, creating bubble remnants that expand into interstellar space. At the heart of bubbles like these are small, dense neutron stars or black holes, the remains of what once shone brightly as a star. http://www.esa.int/spaceinimages/Images/2014/06/Pulsar_encased_in_supernova_bubble
