The Dazzling Supernova 1987a in Nearby Large Magellanic Cloud Galaxy
This image, released on Feb. 24, 2017, shows Supernova 1987a (center) surrounded by dramatic red clouds of gas and dust within the Large Magellanic Cloud. This supernova, first discovered on Feb. 23, 1987, blazed with the power of 100 million Suns. Since that first sighting, SN 1987A has continued to fascinate astronomers with its spectacular light show. Located in the nearby Large Magellanic Cloud, it was the nearest supernova explosion observed in hundreds of years and the best opportunity yet for astronomers to study the phases before, during, and after the death of a star.
Distance: 168,000 light-years
Clouds of gas and dust in shades of red cover the top of the image and a little bit of the bottom. Right in the middle is Supernova 1987a, the remnant of an exploded star. The site of the supernova is surrounded by an illuminated pinkish ring. Two faint outer rings are also visible. Stars and galaxies shine throughout, giving off red and blue light.
A supernova is the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star.
SN 1987A represents a second type of supernova that can happen in systems where two stars orbit one another and at least one of those stars is an Earth-sized white dwarf. A white dwarf is what is left after a star the size of our sun has run out of fuel. If one white dwarf collides with another or pulls too much matter from its nearby star, the white dwarf can explode.
