When was the Last Super Nova seen? Can we predict when the the next one will be seen? ?

Question

Include Details & Sources pleeeeease =]

Answer 1

I think it was in 1987. Known as SN 1987A

Answer 2

The last two "naked eye" observed supernova  within the Milky Way Galaxy occurred in 1054 and 1604.  This doesn't mean one hasn't happened since, perhaps a star on the other side of the "galactic center" has gone supernova and its distance, plus it's light having to travel through the brightness of the center of our galaxy would render it's light unnoticeable..  This is incredibly likely, since it is argued that most galaxies the size of ours average a supernova every 50 years.  

Supernova in other galaxies are observed fairly regularly.  But you need either a  good telescope or incredible luck with long exposure photography to "view" them.  The brightest of these usually don't break apparent magnitude of 13.  (The limit of the naked eye under perfect viewing conditions is around 6.5).

And no, we cannot predict them.  If you have enough information about a star, you might be able to come up with a range of when it might go supernova, but even this would be immensely tricky to calculate.

Answer 3

fairly often if you're talking about in other galaxies.  With millions of galaxies to look at, and with one supernova happening every 50 years (say) that means that for every 31 million galaxies one supernova is happening every minute.

As to your second question, I guess I just did, didn't I?

Answer 4

in our galaxsee, 1604. just before the invention of the telesscope. g1.0+0.3 was not seen at the time (late 19th century) bcuz there is lots of dust in the way.

can we predict them? no.

Answer 5

The Kepler Star's Supernova was the last supernova which was definitely observed in our Milky Way Galaxy. It was discovered on October 9, 1604, when it was already brighter than all stars in the sky, by several persons including Brunowski in Prague (who notified Kepler), Altobelli in Verona, Clavius in Rome, and Capra and Marius in Padua. Kepler first saw it on October 17, and started a systematic study of the phenomenon, inspired by Tycho's work on the supernova of 1572.

Initially as bright as Mars, the supernova brightened up and surpassed Jupiter in brilliance within a few days. According to a study of Baade 1943, the peak brightness was perhaps close to magnitude -2.25. It was still about as bright as Jupiter when it became invisible in twilight of November. At its reappearance in January 1605, Kepler found it still brighter than Antares, and it remained visible until March, 1606, after a naked-eye visibility of 18 months. From its light curve, it was suspected that this had been a type I supernova.

Our image is a drawing of Kepler of the Supernova 1604 in the foot of Ophiuchus. This image was taken from the Out of This World: The Golden Age of the Celestial Atlas Exhibition of Rare Books from the Collection of the Linda Hall Library.

In 1941, astronomers used the Mt. Wilson 100-inch telescope and identified the gaseous remnant of Kepler's supernova, a faint fan-shaped nebulosity about 40 arc seconds in extent, consisted of filamentsand bright condensations with a total brightness of about magnitude 19. This young supernova remnant has been cataloged as 3C 358 (from its radio emission) and G4.5+6.8 (in David Green's SNR catalog).

The distance of Kepler's supernova is not known, but Burnham estimates, from the assumption of an absolute magnitude -16, an upper limit of about 20,000 light years; absorption could significantly reduce this number though.

To put it simply there is no way to predict the laws of science i.e supernovas and black holes and such.

There will be no way that we can predict the future....unless in the future it turns out to be like an episode of futurama!!
