This artist´ impression of the material around a recently exploded star, known as Supernova 1987A (or SN 1987A), is based on observations which have for the first time revealed a three dimensional view of the distribution of the expelled material. The observations were made by astronomers using ESO´ Very Large Telescope. The original blast was not only powerful, according to the new results, it was also more concentrated in one particular direction. This is a strong indication that the supernova must have been very turbulent, supporting the most recent computer models. This image shows the different elements present in SN 1987A: two outer rings, one inner ring and the deformed, innermost expelled material. Credit: ESO/L. Calçada
