Astronomy Cast Ep. 415: Temperature of the Universe
About | Information | History | Online | Facts | Discovery
The temperature of the Universe can vary a dramatic amount from the hot cores of stars to the vast cold emptiness of deep space. What's the temperature of the Universe now, and what will it be in the future? Join +Fraser Cain and +Pamela Gay for a live episode of Astronomy Cast. We'll record our 30-minute show, and then stay tuned for them to answer questions! Ep. 415: Temperature of the Universe

Nuclear explosions must be hotter than 10 000K, sure you didn't leave out 3 zeros there? It's got to be hot enough to do fusion and the sun is (like you said) 15 million K in the center.

Wow, apparently this show has caught the attention of the flat earth idiots. I can't wait for commercial spaceflight to become affordable enough for normal people to be able to see for themselves. Or so we can just kick them out in to space, either way.

Fake space is always about pretending we know such crap as the temperatures of things millions of miles away. The flat earth is absurd because we've been programmed to believe the lies, like the ball earth.

Fraser's voice booms every so often, my poor eardrums...

Oh look two members of the chosen race tooting each others horns..... You are so unique, intelligent and special.... a real blessing to the earth ... NOT The earth is flat and you are vile and disgusting... #chosen privilege

I think I remember hearing, maybe on the Titanium Physicists podcast, that negative temperatures are possible. The distinction I recall was that temperature is thermodynamically defined as some derivative involving energy and entropy. Basically, things with negative temperature would be very "hot," that is, containing a lot of energy, but that adding more energy would somehow decrease the entropy, giving a negative temperature by definition.

Just to clarify. Galileo dropped a separate probe into Jupiter from the orbiter in 1995. The Galileo orbiter dove into the planet at its end of mission in 2003.

Mr. Universe, what do you think about the temperatures of satellites in the thermosphere. The air temperature exceeds 4000F around them, how do they keep from overheating? Thanks

Epic comment: "I wonder tho, if that's the cause of the great filter that kills everything and all the other alien races are like 'I wonder how hot we can make things'.
Don't ever change!
