What’s The Hottest Hot and Coldest Cold in the Universe?

Hello everyone. Welcome to our channel. In today’s video Smart is the New Sexy is going to explain to you what actually hot and cold mean and what the hottest and coldest known objects in the universe are. Buckle up for an interesting ride with us.

Just for you to know - here’s a simple scale that will help you understand the space environment:

0 Kelvin - absolute zero
0.00000006 Kelvin - temperature of the supermassive black hole
0.0000000006 Kelvin - MIT scientists have cooled a sodium gas to the lowest temperature ever recorded
1 Kelvin - a ghostly nebula shining about 5,000 light-years from Earth is also the coldest known object in the universe. The dead star creating the Boomerang Nebula is sloughing off gas from its shell, which is producing the strangely shaped cosmic object, astronomers have discovered.
44 Kelvin - the average surface temperature on Pluto
184 Kelvin - the lowest natural temperature ever directly recorded at ground level on Earth at the Soviet Vostok Station in Antarctica
331 Kelvin - the hottest temperature ever recorded on Earth was in the Lut Desert of Iran
373 Kelvin - the temperature of the brown dwarf star
735 Kelvin - the hellish average temperature on Venus
11,000 Kelvin - the temperature of Rigel, the blue supergiant star
100,000 Kelvin - the temperature of a very hot white dwarf star
36,000-40,000 Kelvin - Eta Carinae
210,000 Kelvin - the hottest known star, WR 102
600,000 Kelvin - Neutron star. They are so dense that a normal-sized matchbox containing neutron-star material would have a mass of approximately 3 billion tonnes.
