Jupiter's atmosphere heats up under solar wind

Jupiter's atmosphere heats up under solar wind
Sensitive to Jupiter's stratospheric temperatures, these infrared images were recorded by the Cooled Mid-Infrared Camera and Spectrograph (COMICS) at the Subaru Telescope on the summit of Mauna Kea, Hawaii. Scientists used red, blue and yellow to infuse this infrared image; regions of the atmosphere that are more yellow and red indicate the hotter areas. This highlights the auroral heating that occurs at Jupiter's poles, where energy from the solar wind and magnetosphere are deposited. This image was captured on Jan. 12, 2017.

New Earth-based telescope observations show that auroras at Jupiter's poles are heating the planet's atmosphere to a greater depth than previously thought—and that it is a rapid response to the solar wind.

"The solar wind impact at Jupiter is an extreme example of space weather," said James Sinclair of NASA's Jet Propulsion Laboratory in Pasadena, California, who led new research published April 8 in Nature Astronomy. "We're seeing the solar wind having an effect deeper than is normally seen."

Auroras at Earth's poles (known as the at the North Pole and at the South Pole) occur when the energetic particles blown out from the sun (the solar wind) interact with and heat up the gases in the upper atmosphere. The same thing happens at Jupiter, but the new observations show the heating goes two or three times deeper down into its atmosphere than on Earth, into the lower level of Jupiter's upper atmosphere, or stratosphere.

Understanding how the sun's constant outpouring of solar wind interacts with planetary environments is key to better understanding the very nature of how planets and their atmospheres evolve.

"What is startling about the results is that we were able to associate for the first time the variations in solar wind and the response in the stratosphere—and that the response to these variations is so quick for such a large area," said JPL's Glenn Orton, co-author and part of the observing team.

Areas of the atmosphere that are more yellow and red indicate the hotter regions. Aurora produce enhanced and variable heating at Jupiter's poles. The heating occurs when the magnetosphere and the solar wind interact and deposit energy into Jupiter's atmosphere. Images were captured less than a day apart, from Jan. 11-12, 2017, and illustrate how quickly the atmosphere varied in response to the solar wind. Credit: NAOJ/NASA/JPL-Caltech

Within a day of the hitting Jupiter, the chemistry in its atmosphere changed and its temperature rose, the team found. An infrared image captured during their observing campaign in January, February and May of 2017 clearly shows hot spots near the poles, where Jupiter's auroras are. The scientists based their findings on observations by the Subaru Telescope, atop the summit of Mauna Kea in Hawaii, which is operated by the National Astronomical Observatory of Japan.

The telescope's Cooled Mid-Infrared Camera and Spectograph (COMICS) recorded thermal images—which capture areas of higher or lower temperatures—of Jupiter's stratosphere.

"Such heating and may tell us something about other planets with harsh environments, and even early Earth," said Yasumasa Kasaba of Tohoku University, who also worked on the observing team.

Well what do you know? Solar activity can heat a planet. Even though the TSI drops during solar storms temps can go up. I bet this doesn't change a thing with the AGW acolytes.

Hmm, solar winds can heat up the atmosphere... so much for man made global warming. This will never hit the mainstream news and will be ignored by the eco nazis. Lets sweep this under the rug asap.

What crap media, no mention of actually 'how much' the temperature rose.

The southern auroral CH4 emission increased in brightness temperature by about 3.8 K between 15:50 UT, 11 January and 12:57 UT, 12 January, during a predicted solar-wind compression.

jonesdumb, you have yet to explain how the TSI is relevant when it has been shown the TSI drops .3% [three times the variation of the complete solar cycle] during X-flare events, for example. Given the above observation that SW directly affects atmospheric chemistry and temperatures it seems moronic to rely entirely on TSI as the only solar related factor to model the Earth's climate.

Because, you clown, this is long term climate, not an 11 year half cycle that has been occurring for billions of years. Has the solar activity increased since the industrial revolution? Lessened? Stayed the same? It is very closely monitored. If it is heating parts of the atmosphere now, it was also doing so 100, 1000, 10 000 etc. years ago. Lern to scienz.

Has the solar activity increased since the industrial revolution?

Yes, as a matter of fact it did, it was called the solar maximum which has come and gone. You know that pause, that was the peak and we are on the way back down the chart.

And temperatures are still rising, which kind of screws that observation, doesn't it?

Is that all you've ever got, you pathetic oaf? Every single time one of your dogmatic beliefs takes a kicking, it's all to do with a conspiracy, or fixing the data, etc. You really are pathetic, particularly given the unscientific crap you believe.

@cantdrive85.

What is it with you and climate science, mate? Can't you see the marginal effect is minimal compared to the solar insOlation inputs directly rather than via solar wind impacts at poles? Then there's the difference that on Earth, insOlation is huge compared to that farther out at Jupiter. And again, you have been told that all solar energy inputs are already part of longterm climate balance/variability. So your ongoing attempts to make mountains out of such 'molehill factors' only demonstrates you don't actually understand the most impactful physics/dynamics involved; OR that you're just another of Russian/GOP/Fossil troll-factory 'weaponised stupids' brainwashed with propaganda spiels that have been long exposed/falsified. Please stop being part of the climate change problem; be part of the solution. Think for yourself; instead of trolling stupidly for criminal/political/sociopathic types/profits. Former deniers all over have wised up; do likewise, mate. :)

This from you is particularly galling, dishonest and denialist, mate:

Have a look at the current evolving reality under your nose:

https://www.ourpl...cenes-wa

Add those to all the many realities pointed out for you over recent years, and then wise up to what's going on with AGW-related evolving catastrophe right under your nose if we don't start being serious about preventative measures asap. Be a reasonable thinking human instead of a political/criminal stooge for those who don't give a damn for you, your family now or in the future as long as the criminals/political bastards make profits and retain power against the interests of future humanity. Good luck to us all. :)

"adjusted" is AGWism for "cooked". Thus, you get man-made..er...excuse me...AGW Cult warming.

Gee, the article says aurora on Earth doesn't penetrate deeply into the atmosphere; on Jupiter apparently it does.

So much for the AGCC denier fest. Maybe you should read the damn article.

In terms of the Earth's aurorae, we are basically talking about heating of the thermosphere.

All layers of the atmosphere are coupled, heat and energy doesn't just enter to a certain layer and stop and dissipate without effect. The Birkeland currents that transfer this energy wrap completely around the Earth, like a tennis ball in a sock. It is well understood the ionosphere is coupled to the surface, through the various layers of the atmosphere. The heat/energy is delivered Earth's entire electric circuit.

Conspiracist loon.

Did you miss all the exposure of the Russian-funded accounts opened on social media to spread disinformation etc, mate? They were proven to have suckered American idiots as part of the Russian-played 'weaponised stupids' that were unwittingly doing Putin's bidding while they thought they were being 'patriotic Americans' believing/disseminating Putin's agenda/propaganda/psyops lies. So, either you are one of the naivest and/or most uninformed posters here about the reality under your very nose, or else you are one of Putin's 'weaponised stupids' on the matter of climate change....amongst other things. Wise up, @cantdrive. Leave politics and trolling propaganda out of it and just stick to arguing based on science not beliefs/ignorance. :)

I discuss how the TSI is but a fraction of the energy which the Earth receives from the Sun, you know, science.
You however are discussing Putin conspiracy theories and other such nonsense, not science. You need to quit your crank science based trolling of me. Ok snookems? <;0 ~:

You know, when thousands of scientific papers say you're wrong, and you claim the scientists are faking the data, that's a conspiracy theory.

Science is not a popularity contest nor is it an example of the democratic process. Those thousands of papers are fundamentally flawed as they don't include all of the energy received by Earth. And the "scientists" readily admit to adjusting the historical records, no conspiracy just truth.

I don't troll, mate. I objectively observe and comment accordingly as indicated based on my interlocutors' own posts/baits/trolls etc. You are the one baiting and trolling, insulting, claiming conspiracies, @cd. If you can't see that, then there is no hope for your returning 'sane and safe' from 'conspiracy land'. It's your political/religious motivated denialist drivel that marks you as a Russian/GOP/Fossil troll-factory stooge, mate. Else don't keep cluttering the threads with such obvious unscientific denialist crap, and I won't need to confront you with same.

Nothing pointless about it. Just pointing out that you are scientifically illiterate. As most people already know. And I think you'll find that you are the crackpot, by definition. You are an EU cultist. Goes with the territory.

No matter how I parse that response of yours, @cd, it 'reads' as a non-sequitur. Can you clarify exactly how that response relates to and explains my longstanding point (re atmosphere 'lagging' and input-output balance determined thereby of all solar inputs/variables already long present in Earth's climate system for millennia) which I have made before to you using the example of planet Mercury? Thanks. :)
