A Visual History of Supernova

This is so cool, especially on as big a monitor. And BOSS has discovered 132 of them so far!

It really is amazing Peter. Well done to BOSS for their contribution as well.
Have a Safe and Happy Christmas.

During 2005-2006 there is an arc formed by the discovered S/N's. Is there a scientific reason for the arc, or is it purely random.

[Atmos]

Looking at them, they all appear to have been detected by SDSS (Sloan Digital Sky Survey) so I would assume that it is just a bias towards the Sloan survey looking at that part of sky?

[PeterM]

The Sloan Digital Sky Survey II was very active in SN discoveries in that part of the sky those years.

Wow!
Rather reminds me of a similar graphic illustrating each nuclear weapon test around the globe from 1945 onward:

Of course, the energies involved are rather less than with SN...!

Yeah, that's pretty cool...almost 10,000 SN's but none in our galaxy since around 1600....gotta be soon, can't wait :D

Thanks guys for the explanation. Still amazing that they form a nice arc.

Cheers
