Confirmed: Uranus Really Is Hotter Than It Has Any Right to Be

I've often thought of my anus as the only gateway to hell
I've had good luck with fiber + probiotic = happy bottom. (But check with your doctor.)

So what causes this? The article doesn’t really say. Even though other gas giants do this too. What’s the theory on this?
i assume nuclear decay processes in its interior
i.e. uranium decays into lead and that process releases some heat continuously for a very long time
it also happens on earth, though i don't have any exact number for it. AFAIK, it's what keeps the earth's interior warm. otherwise it would have cooled down a lot more since the earth formed a few billion years ago.

My thoughts well summarised haha they are gas planets with significant mass. In astrophysics class I am sure they said gases heat up under gravity and stable fusion is obtained if enough heat/gravity/mass. They should still heat in the absence of fusion. I haven't read the research but I assume that's accounted for. So is the remaining heat chemical or nuclear? Maybe they have some heavy radioactive elements pumping out heat too? Or stored primordial heat being slowly released?
it's not chemical, that much i can tell you. there was a study done in 1800 iirc where they contemplated what gives the sun its enormous power and they figured out that if the sun was a solid ball of coal burning slowly, it wouldn't last longer than 200 years iirc, at the enormous rate of power it emits. it's a nuclear process
these nuclear processes can be very long-running. uranium takes billions of years to decay. it's probable that a lot of planets have uranium in their interior and that heats up the planet from the inside.

Uranus isn't the sun though and the power output is many orders of magnitude lower

They don't seem to have a working theory yet, they just noticed the historical temps are higher than expected. Exited to see what more research reveals!
Could there somehow be a new form of life on uranus causing it to be hotter than expected?

That all makes sense.
But if the inner planets do this too, then why is it such a mystery? Sounds like every planet does this then.

A new analysis of decades' worth of observations has revealed that Uranus does indeed emit more heat than it receives from the rays of the Sun.
Myanus has every right to be this hot

The innuendo was kind of fun for a few comments, but thank you for finally asking the question that was the reason I opened this thread.

That's the spirit!

I think we need to probe Uranus to find out why.
