During the next week or so, you should be able to see this supernova in the Pinwheel Galaxy with a good pair of binoculars, or a small telescope, as it waxes to its maximum brightness on September 9th.
The supernova was discovered just hours after the explosion. Astronomers are pointing every telescope they can manage at it, so this is going to be very well studied over the next decade, something high-schoolers interested in astronomy might consider.
It’s worth reiterating that since the supernova is occurring 21 million light years away, this star exploded 21 million years ago.
The video below explains where to look to find it in the night sky.
