 Meet KELT-9b, the Hottest Exoplanet Ever Discovered

The exoplanet’s host star blasts it with so much radiation that it will someday evaporate.
 
By JoAnna Wendel 22 hours ago

KELT-9b may just be the weirdest exoplanet astronomer Scott Gaudi has ever found. Gaudi, a researcher at The Ohio State University in Columbus, is the lead author of a paper published today in Nature describing the newly discovered hot, gassy exoplanet that is 3 times the size of Jupiter and located 650 light-years away from Earth.

The newly found exoplanet is tidally locked to its host star, meaning one side eternally faces a blast of radiant heat, Gaudi said. The 4300°C temperature of KELT-9b’s “dayside” is only about 1000°C cooler than the surface of our Sun.

Thanks for the ping, @Freya!  "Wow" is right!

The extremes and scales in the universe are astounding.

We speak of the habitable zone of not to hot or too cold but on a universal scale we're creatures of the extreme cold. Temperatures are capable of only getting a few hundred degrees colder but theoretically trillions of degrees hotter.

Yup.

Obliquely related, decades ago, I had a dream about being an astronaut who encountered a race that saw logarithmic scales the way we see linear ones. I wrote a short story based on it.  Unfortunately,  my conscious mind isn't nearly as smart as my subconscious, and I couldn't remember some of the interesting observations (i.e., subconscious musings) I'd had.

It's funny to think that this creature...



...would also be in a "relatively cold" environment, all things considered.

@Suppressed

Yeah,I'm betting it would be a lot funnier to think of it than it would be to bump into it.
Anyone who isn't paranoid in 2021 just isn't thinking clearly!
