Ah, New Mexico!

Scientists [at Sandia National Labs] have produced superheated gas exceeding temperatures of 2 billion degrees Kelvin, or 3.6 billion degrees Fahrenheit.

This is hotter than the interior of our sun, which is about 15 million degrees Kelvin, and also hotter than any previous temperature ever achieved on Earth, they say.

They don't know how they did it.

Emphasis mine. Half of me says, "Cool!" Half of me wishes I were further from Albuquerque.
