That's Hot

Where are the hottest places in the universe?

The hottest temperature measured on Earth’s surface was in the Lut Desert in Iran. In 2005, it reached 159 degrees Fahrenheit there.

The hottest place in our solar system is the center of our Sun, a sizzling 27 million degrees Fahrenheit.

Two of the hottest known places in the universe are:
- the cores of exploding stars called supernovas, at 100 billion degrees Fahrenheit, and
- inside gamma ray bursts— mysterious, energetic explosions originating from distant galaxies— estimated at a blistering 1 trillion degrees Fahrenheit.


What’s the Ultimate Hot?

The Big Bang, with an estimated temperature of 1-followed-by-32-zeros Kelvin, equivalent to 1.8-followed-by-32-zeros Fahrenheit.

Now that’s hot!

Um, 1 degree Kelvin is equivalent to 1.8 degrees Fahrenheit, not 457.8.

Thanks, bobnxena, for spotting my blunder and especially for alerting me to it. I've corrected the post for future readers.
