That did cross my mind.

But the headine said explosion, and I like writing splodey. Pretty sure the astronomer that I heard on the radio earlier described it as an explosion too.

So when does an explosion stop being an explosion?

Yup, I think, that 30Bn X the average power of the Sun in a volume of only 100 solar systems is pretty splody. 3 years is not long for an shockwave from an explosion to travel about 5x further than Voyager.

NASA's Mars Sample Return mission is is already projected to cost $10 billion (and there are many reasons to think that it will cost much, much more.) linky.

Which means the Unknown Pleasures album cover is relevant to known cosmology.

A quick heads-up that the launch of the ESA Euclid telescope is due to be at 16:11 BST (15:11 UT) today.

It can be watched on the ESA youtube channel https://www.youtube.com/watch?v=ZyNEAEFh-Cc

There are two primary areas of investigation
- Dark Energy.
- Dark Matter.
