It was found in the Large Magellanic Cloud in the Dorado constellation. Scientist have observed L.M.C. closely and have found out that is seems to be a much smaller galaxy orbiting our much larger Milky Way Galaxy.]]> 2019-04-02 19:11:50 UTC https://padlet.com/1205117/soqp9fzse5sg/wish/347799688 How long has it been observed? 1205117 https://padlet.com/1205117/soqp9fzse5sg/wish/348250473 Hubble has constantly observed 1987A, acquiring hundreds of images, and the Chandra telescope began observing the supernova shortly after its deployment.
The SN has been observed for about 32 years since it's discovery.  
Three decades ago, astronomers spotted one of the brightest exploding stars in more than 400 years (The last SN spotted was in 1604). The gigantic supernova exploded with the power of 100 million suns for several months following its discovery on Feb. 23, 1987. Like most Supernovas this one was could be spotted in the day  if you were in Earth's southern hemisphere because of it's close proximity to The Milky Way, but could also be seen at night across the globe.]]> 2019-04-03 19:12:18 UTC https://padlet.com/1205117/soqp9fzse5sg/wish/348250473 How did it get it's ring? 1205117 https://padlet.com/1205117/soqp9fzse5sg/wish/348255643 The latest data from powerful telescopes indicate that SN 1987A has passed an important threshold. The supernova shock wave is moving beyond the dense ring of gas produced late in the life of the pre-supernova star when a fast outflow or wind from the star collided with a slower wind generated in an earlier  red super giant phase of the star's life. What lies beyond the ring is poorly known at present, and depends on the details of the evolution of the star when it was a red super giant.]]> 2019-04-03 19:25:30 UTC https://padlet.com/1205117/soqp9fzse5sg/wish/348255643 Padlet Summary 1205117 https://padlet.com/1205117/soqp9fzse5sg/wish/351256225 2019-04-12 17:42:54 UTC https://padlet.com/1205117/soqp9fzse5sg/wish/351256225 Bibliography 1205117 https://padlet.com/1205117/soqp9fzse5sg/wish/351258682 http://chandra.harvard.edu/
