A science thread on /sci/?

Who's only purpose is to make known an interesting and subtly awesome event in the scientific community?!

With no attempt at trolling?!?!

And no mention of ideologies?!!!?!?

You, Sir, are awesome.

Alright /sci/! It's trivia time!

Flex some knowledge-muscles and answer the following trivia question:

Indicated in the image are three observed "features" on Neptune, each with their own "name".

What are these three features called?

(If you can't get #1, please leave /sci/)

>>3390154

The Eye of Sauron?

Correct! However, the third one is often (rather humourously) referred to as "Wizard's Eye".

3 is the lost city of atlantis

Neptune is such a beauty, its cold and distant yet devastatingly gorgeous.

like Nicole Kidman.

>> No.3390182

>>3390162
You probably mean "Saturnon"?

How come Neptune so far away from the Sun has so much energy to have supersonic storms in it? I was wondering about it since it allegedly has very violent atmosphere yet there SEEMINGLY isn't any energy source for it.
What is the reason for this strong atmospheric storms from physics point of view - is it just that very big portion of Sun's energy is efficiently converted to kinetic or what?

all that gas .. floating there, unclaimed.

Im sure as shit Texaco have evil plans to suck on that titty.

Well if Neptune has a rocky core then it will have some radioactive heating like our core does.

Dumb question, but what is radioactive heating? How would it generate energy for Neptune?

>> No.3390225

>>3390216
Geothermal gradient is the rate of increasing temperature with respect to increasing depth in the Earth's interior. Away from tectonic plate boundaries, it is 25–30°C per km of depth in most of the world.[1] Strictly speaking, geo-thermal necessarily refers to the Earth but the concept may be applied to other planets. The Earth's internal heat comes from a combination of residual heat from planetary accretion (about 20%) and heat produced through radioactive decay (80%).[2] The major heat-producing isotopes in the Earth are potassium-40, uranium-238, uranium-235, and thorium-232.[3] At the center of the planet, the temperature may be up to 7,000 K and the pressure could reach 360 GPa.[4] Because much of the heat is provided by radioactive decay, scientists believe that early in Earth history, before isotopes with short half-lives had been depleted, Earth's heat production would have been much higher. This extra heat production, which was twice that of present-day at approximately 3 billion years ago,[2] would have increased temperature gradients within the Earth, increasing the rates of mantle convection and plate tectonics, and allowing the production of igneous rocks such as komatiites that are not formed today

That sounds strange (though probably the only option), how much heat can be produced in this way?

>> No.3390228

>>3390216
When radioactive elements decay they release energy as heat, radioactive heating is what keeps the earth's core hot. This heat would conduct through the core to the fluid above on Neptune and as we know from earth differences in temperature are what drive a lot of the weather. Also friction slows wind down, in the upper atmosphere of Neptune all air has to hit is itself.
