Supernova remnant (2nd of 2)

Supernova remnant

This 1994 image from the Hubble Space Telescope is of the site around Supernova 1987A. It shows a ring of dust and gas that has been ejected from the surface of a dying star. Albert Jones was one of the co-discoverers of this famous supernova, which first became visible in February 1987. A supernova is evidence of the death throes of a massive star, in this case one which exploded about 170,000 years ago. It had taken that long for light from the exploding star to reach earth.
