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 20th century astronomy. In this HST image , the pulsar is the left most of the two bright central stars.
