The Hottest Things in the Universe

🌡️The human body has an internal temperature that fluctuates by about one degree Fahrenheit throughout the day.

🔥The surface of the Sun clocks in at 10,000 degrees Fahrenheit, while its core reaches temperatures of 28 million degrees Fahrenheit.

🌋Lava, fresh out of the ground, can reach temperatures of 2,000 degrees Fahrenheit.

⚛️At temperatures as hot as the Sun, matter exists in a state called plasma, where electrons wander away from the nuclei.

💥Above a certain temperature known as the Planck temperature, our current theories about temperature and energy break down.

What is the hottest temperature ever recorded on Earth?

—The highest recorded air temperature on Earth was 129 degrees Fahrenheit in Death Valley.

How hot does lava get?

—Lava can reach temperatures of 2,000 degrees Fahrenheit.

What is the temperature of the Sun's core?

—The Sun's core reaches temperatures of 28 million degrees Fahrenheit.

What is plasma?

—Plasma is a state of matter where electrons separate from their nuclei, and it exists at temperatures as hot as the Sun.

What happens at temperatures hotter than the Planck temperature?

—At temperatures hotter than the Planck temperature, our current theories about temperature and energy break down.
