Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. Chinese astronomers reported that a star in the constellation of Taurus suddenly became as bright as the full Moon. Fading slowly, it remained visible for over a year. The core of the star collapsed to form a rotating neutron star or pulsar , one of the most exotic objects known to modern astronomers. Only 10 kilometers wide but more massive than the sun, the pulsar's energy drives the dynamics and emission of the nebula itself which is more than 10 light-years across.
