Re: APOD: Cooling Neutron Star (2017 May 01)


Okay, so two neutrons fall in love, merge, and create little baby neutrinos. Why does that make them superfluidic?

The explanation is really incomplete. I'm tempted to go find out in Wikipedia, but I know I'd be trapped there for hours with dozens of browser tabs open.

Mmm, I don't know about that, Ann. Sure, you're more likely to see a new one in a dust lane, but a million years is just an eyeblink. A star's life is ten thousand times longer than that.

Re: Gaia: Two Million Stars on the Move

wish list

2. Add more contrast. The brightness range of stars vary tremendously, way more than we even can accurately depict, but this sim doesn't show bright stars at all.[/list] Yeah.
