Imagine a planet that gets roasted alive… every 111 days.
Not melted slowly.
Flash-fried.
1,100°F hotter in a matter of hours.
That's not science fiction.
That's HD 80606 b — and NASA's James Webb Space Telescope just caught it in the act.
It sits about 217 light-years away in the constellation Ursa Major.
Four times the mass of Jupiter.
A gas giant with an attitude problem.
Most "hot Jupiters" hug their stars in tight, lazy circles.
Not this one.
HD 80606 b swings on one of the most stretched-out orbits ever found — an eccentricity of 0.93 (a perfect circle is 0).
It spends most of its 111.4-day year out in the cold…
then slingshots toward its Sun-like star like a moth hurled at a bonfire.
Using its Mid-Infrared Instrument, Webb watched the planet before, during, and after its closest approach.
What it recorded was wild:
Yes. Glass clouds. Drifting through skies of evaporated rock.
That's the weather forecast on HD 80606 b.
Most exoplanets are static postcards.
This one is a live show.
Principal investigator Tiffany Kataria of NASA's JPL calls it "one of the most extreme" hot Jupiters ever studied.
Co-investigator Laura C. Mayorga put it simply: one orbit gives you a front-row seat to dramatic shifts in temperature and chemistry.
It's basically a natural lab.
A stress test for planetary atmospheres.
A way to ask: what happens when you slam a world with sudden, brutal heat — and then let it cool?
And it repeats the experiment every 111 days, free of charge.
No, nothing is living there.
This is hell with weather.
But every spike Webb records is a clue about how any planet — including ones that might host life — reacts to the moods of its star.
Spitzer first nicknamed it "the roasted exoplanet."
Webb just turned up the heat on what we can see.
And the team says they've barely started reading the data.
The most extreme planet we know of is finally talking.
We're just learning how to listen.
That's all for now!
