Crab Nebula (M1). Composite X-ray,infrared and optical image of the Crab Nebula,the remnant of a supernova. In the centre of the supernova remnant is the remains of the star's core,which has formed a pulsar (white dot),or neutron star rotating 30 times a second and emitting regular pulses of radiation. When a large star dies,gas shells explode outwards and collide with interstellar material. The energy of the collision ionises the gas,causing it to glow. The Crab Nebula lies 6000 light years from Earth in the constellation Taurus. X-ray data from Chandra (blue),visible light data from Hubble (red and yellow) and infrared data from Spitzer (purple) have been combined to form this image | |
