New observations of a jet-emitting black hole show astonishing temperatures inside the jets of 10 trillion degrees Kelvin - a toasty 18 trillion degrees Fahrenheit. This new measurement shows that quasars can blow far past the theoretical temperature limit of 100 billion degrees Kelvin (179 billion degrees Fahrenheit), which has scientists puzzled.
"This result is very challenging to explain with our current understanding of how relativistic jets of quasars radiate," said lead author Yuri Kovalev of the Moscow's Lebedev Physical Institute in a statement.
Observations of quasar 3C 273 were done with the Russian Skeptr-R satellite working in concert with three ground observatories as part of the larger RadioAstron mission. Quasars are supermassive black holes that emit intense jets of radiation.

Previously, it was believed there was a limit to the temperature because the electrons inside the jet would produce X-rays and gamma rays, interact with each other and cool down.
