A CERN experiment at the Large Hadron Collider created the highest recorded temperature ever when it reached 9.9 trillion degrees Fahrenheit. The experiment was meant to make a primordial goop called a quark–gluon plasma behave like a frictionless fluid. That's more than 366,000 times hotter than the center of the Sun.
Hottest Thing on Earth: X-rays Heat Metal to 3.6 Million Degrees. The chamber in which aluminum was converted to "hot dense matter" via x-ray bombardment.
A supernova is the hottest thing in the universe. The temperatures at the core during an explosion skyrocket up to 6000X the temperature of the sun's core.
Stellar black holes are very cold: they have a temperature of nearly absolute zero – which is zero Kelvin, or −273.15 degrees Celsius.
The temperature in a supernova can reach 1,000,000,000 degrees Celsius. This high temperature can lead to the production of new elements which may appear in the new nebula that results after the supernova explosion.
Lightning is hot. Really hot. It can reach temperatures as high as 50,000 degrees Fahrenheit, five times hotter than the surface of the sun, and even hotter than lava here on Earth.
In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun).
Answer and Explanation: Magma is hotter than lava, depending on how recently the lava reached the surface and if the magma and lava are from the same magma chamber below the volcano.
Lava won't kill you if it briefly touches you. You would get a nasty burn, but unless you fell in and couldn't get out, you wouldn't die.
At one extreme is something called Planck temperature, and is equivalent to 1.417 x 1032 Kelvin (or something like 141 million million million million million degrees). This is what people will often refer to as the 'absolute hot'.
You would never fall into a lava lake the way you would a swimming pool, the molten rock is much more dense, so you would simply land on it, sink a little, and be burned."
Up to 50,000 degrees Fahrenheit, maybe even more.
It's right here on Earth at the Large Hadron Collider (LHC). When they smash gold particles together, for a split second, the temperature reaches 7.2 trillion degrees Fahrenheit. That's hotter than a supernova explosion.
In fact, the corona is hundreds of times hotter than the sun's surface. According to NASA, the corona is heated by tiny explosions called nanoflares. These bursts of heat can individually reach incredibly hot temperatures of up to 18 million degrees Fahrenheit.
The flash reaches temperatures of about 30,000 K. Lightning is visible as a flash of light because of both incandescence (due to its high temperature it glows blue-white) and luminescence (excitation of nitrogen gas in the atmosphere).
The color of the bolt depends on how hot it is; the hotter the lightning, the closer the color will be to the end of the spectrum. The color spectrum in this case start with infared which is red and the coolest up to ultraviolet which appears violet and is the hottest.
A CERN experiment at the Large Hadron Collider created the highest recorded temperature ever when it reached 9.9 trillion degrees Fahrenheit.
According to NASA, the Boomerang Nebula is the coldest spot in the known cosmos, with a temperature of one degree Kelvin. One degree Kelvin is 458 degrees Fahrenheit, or roughly 272 degrees Celsius. The lowest temperature recorded on Earth was 128.6 degrees Fahrenheit in Vostok, Antarctica.
The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It's so wide that light takes about 10 billion years to move across the entire structure.
Perhaps the strangest colors reported are instances of pink or green lightning seen during snowstorms. The phenomenon, known as”thundersnow”, is rare. The unique sky color is caused as snowflakes refract and reflect the white bolt in a unique way.
A deep red fire is about 600–800° C (1112–1800° F). An orange-yellow fire is about 1100° C (2012° F). A white flame is hotter than both, having temperatures of 1300–1500° C (2400–2700° F). A dazzling white flame is the hottest flame of all, with a range of 1400–1650° C (2600–3000° F).
In snowstorms, where it is somewhat rare, pink and green are often described as colors of lightning. Haze, dust, moisture, raindrops and any other particles in the atmosphere will affect the color by absorbing or diffracting a portion of the white light of lightning.
Lava flows typically move slowly enough to outrun them, but they will destroy everything in their path.
While your lungs would almost undoubtedly be irrevocably charred from the hot air above the lava (assuming relatively static air conditions over the lava), it takes about 80 seconds for the average human to fall unconscious from lack of oxygen, and I highly doubt your body will last that long.
