    Why start a thread to ask a question about temperature?

    My way of saying rather than goggling let someone else do it and don't burn up your quota.

    I thought that was what you meant but I still don't get it. If he can access sciforums he is using up the same data as using Google isn't he?

    We need data on the data it seems.
    Maybe there is more to it than my first casual assesment.
    Maybe we should wait for an answer to your original question.

    What makes Saturn's atmosphere so hot
    New mapping of the giant planet's upper atmosphere reveals likely reason why it's so hot
    Date:
    April 6, 2020
    Source:
    University of Arizona
    Summary:
    New analysis of data from NASA's Cassini spacecraft found that electric currents, triggered by interactions between solar winds and charged particles from Saturn's moons, spark the auroras and heat the planet's upper atmosphere.

    The upper layers in the atmospheres of gas giants -- Saturn, Jupiter, Uranus and Neptune -- are hot, just like Earth's. But unlike Earth, the Sun is too far from these outer planets to account for the high temperatures. Their heat source has been one of the great mysteries of planetary science.

    New analysis of data from NASA's Cassini spacecraft finds a viable explanation for what's keeping the upper layers of Saturn, and possibly the other gas giants, so hot: auroras at the planet's north and south poles. Electric currents, triggered by interactions between solar winds and charged particles from Saturn's moons, spark the auroras and heat the upper atmosphere. (As with Earth's northern lights, studying auroras tells scientists what's going on in the planet's atmosphere.)

    The work, published today in Nature Astronomy, is the most complete mapping yet of both temperature and density of a gas giant's upper atmosphere -- a region that has been poorly understood.

    "Understanding the dynamics really requires a global view. This dataset is the first time we've been able to look at the upper atmosphere from pole to pole while also seeing how temperature changes with depth," said Zarah Brown, lead author of the study and a graduate student in the University of Arizona Lunar and Planetary Laboratory.

    Yeh
    that's the article that sparked my curiosity
    unfortunately I could not find a number to anchor "so hot"
    ergo my question
    Is the "so hot" the 135k that evan posted, or hotter?
    also
    "how temperature changes with depth"
    is equally unanchored/adrift

    (gee darn)

    homework
    ok
    just a curiosity
    more online research
    It seems to be quite hot near saturn's "surface" 134 degrees F
    interesting
    How does one determine the "surface" of a gas giant?

    If posted in any other thread, the poster would be remanded for being off-topic and asked to start a new thread, don't you see?

    I'm not questioning which forum it's in. Asking a question with a straightforward answer is hardly the subject of a thread.

    Should I start a thread called what color is a strawberry?

    Alas, there is no one "straightforward answer".
    Perhaps, the question was poorly phrased.
    The more one knows, the better can one phrase the questions which lead to answers which lead to more questions which lead to answers which lead to more questions....repeat.......

    layers of atmosphere
    assuming no hard surface, elevation becomes problematic?

    Why? The planet still has a centre.

    I thought you just used a "like" when that happened to me recently.
    Exactly!

    That's why I even bothered with this casual comment. But watch, I'll be advised to start a new thread on "reasons why to start a new thread".....

    Why is a strawberry red, it is because of microtubules?

    No, but viruses multiply by using the host cell's microtubules. Check it out.

    And now all this will be transferred to my thread on the possible role of microtubules in consciousness.
