Latest SN 1987A Stories
By analyzing the remnant of a recently-exploded star, researchers have confirmed what computer models have long predicted – when stellar giants die, they do so in a lopsided fashion, as the core of the star is flung off in one direction and debris is sent flying the opposite way.
In 1987 astronomers witnessed the violent death of a giant star in the form of a supernova, and now researchers have published results of their extensive ‘autopsy’ which yielded surprising results.

A new image of a recent supernova could offer up insight to scientists about how galaxies became so dusty.
A group of international scientists have observed as the largest known star in the Universe tore itself apart.
An international team of astronomers detected surprisingly low temperatures in the remnant of the supernova 1987A, helping to explain the mystery of why space is filled with dust grains and molecules.
An observation of the Large Magellanic Cloud (LMC) in February of 1987 left astronomers thinking they had discovered the beginnings of a new star. However, what they had witnessed was the end of one of the brightest supernovae seen from Earth since the invention of the telescope some 400 years earlier.
A thousand-year-old supernova has given the European Space Observatory's Very Large Telescope ample opportunity to gain some clues about the origins of cosmic rays.
Radioactive titanium associated with supernova remnant 1987A has been directly detected by ESA's Integral space observatory. The glowing remnant around the exploded star has likely been powered by the decaying from this titanium for the last 20 years.
NASA reported recently that astronomers can say with certainty there is no fear of a supernova being close enough to hurt Earth, especially by 2012.
Supernova Remnant -- A supernova remnant (SNR) is made up of the materials left behind by the gigantic explosion of a star in a supernova. There are two possible routes to this end: either a massive star may cease to generate fusion energy in its core, and collapse inward under the force of its own gravity, or a white dwarf star may accumulate material from a companion star until it reaches a critical mass and undergoes a similar collapse. In either case, the resulting supernova...
Supernova 1987a -- Supernova 1987a was a supernova in the Large Magellanic Cloud, a nearby dwarf galaxy. It occurred approximately 50 kiloparsecs from Earth, the closest supernova since Supernova 1604, which occurred in the Milky Way itself. The light from the supernova reached Earth on February 23, 1987. Its brightness peaked in May with a magnitude of about 3 and slowly declined in the following months. It was modern astronomers' first opportunity to see a supernova up close....
