What's five times hotter than the sun and capable of sending a DeLorean back to the future? Yep, the answer is a bolt of lightning, which can reach temperatures of roughly 30,000 kelvins (53,540 degrees Fahrenheit). The sun, on the other hand, is eclipsed in this case - its surface temperature is just 6,000 kelvins (10,340 degrees Fahrenheit).
The Sound of Thunder. Regardless of whether lightning is positive or negative, thunder is produced the same way. Thunder is the acoustic shock wave resulting from the extreme heat generated by a lightning flash. Lightning can be as hot as 54,000Â°F (30,000Â°C), a temperature that is five times hotter than surface of the sun!
