Space and stuff

[chrismpw]

There are plenty of excellent channels with plenty of excellent programmes. There are just so many channels that there is bound to be a lot of dross as well.

I'll be honest, on average I find about 1 interesting programme a fortnight. Undoubtedly there might be some good stuff, but I've pretty much given up looking. It's like looking through a beach to find a blue grain of sand.
Youtube is my tv these days .... Although if the ads get any more obtrusive I'll soon be ditching that too.

I've just been reading this about the Parker space probe. It blows my mind that the surface of the sun is 'only' about 6,000ºC yet the corona around the sun is potentially between 2m and 3m ºC and that's the area the probing will be going in to.

It seems staggering that something from earth can actually survive temperatures of up to 3m ºC. Have those kind of temperatures ever been recreated on earth to do some testing?

Try her indoor's Lob Scouse, you have to blow on it before you eat it.

Roscosmos has released footage taken from an on board camera during the Soyuz launch the other week:

So, as far as I am aware, the area it is passing through that is 2-3M degrees is not a very dense area (or is it fluid density? Are they different?). Think of opening the oven door when it is heated to 200 deg C.......you can stick your hand in there without much discomfort - because the air isn't very dense. Now stick your hand in a pot of boiling water........

OUCH! Didn't half hurt, that.

It does look a little bit like the mother ship in Independence Day.

But looks more like a rock.

I'm more or less neutral on the use of cannabis in mainstream culture, but I am all for drug testing academics upon submission of new papers, especially physicists
