Made another nova. The shockwave hasn't even reached the farthest away planet, which is too small to be seen on this low res image, as it was only a few pixels wide. The bipolar outflows from the star are gamma bursts, which pierce the main shock front.
I think this one is a little better than the first one I made, reminds me a lot of star trek generations if you have seen the nova in that film.
Original size is 16 times bigger than this. 6144^2
