Four Bright Knots of Superheated Gas in Supernova 1987A Ring
Image processing is used to emphasize four new bright knots of superheated gas discovered in the February 2 Hubble observations. The brightest knot, at the far right, was seen in 1997. Astronomers have been waiting several years to see more of the ring light-up as the supernova shockwave smashes into it. This is the first definitive sign of the full onset of a dramatic and violent collision which will continue over the next few years, rejuvenating SN1987A as a powerful source of X-ray and radio emissions.
