Ten years ago, on February 23, 1987, a star exploded in the sky on the night of the southern hemisphere. Its brightness indicated the death of the star. It was the brightest supernovel seen for four centuries. It was called SN1987 A to that star that was a manga for astronomers. In fact, its proximity allowed to see for the first time the ring of light that surrounded the supernova evolving and comparing it with the initially explosive geometry.
Astronomers have used the Hubble space telescope to analyze the supernova. The images sent by the telescope show how the supernova extends throughout the sixth part of the light year. It has an aspa-shaped structure and two expanding “drops of waste”, which move about ten million kilometers per hour. The structure of the inner ring would suppose that the original star could have another close.
The supernova will be analyzed in 2002. By then the remains of the explosion should reach the central ring and illuminate the surrounding area.
