Jupiter's Third Red Spot

Jupiter's Great Red Spot, the solar system's largest (and longest-lived) storm, was joined by another in 2006, dubbed Red Spot Junior. Now a third red spot near the first two has been photographed by the Hubble space telescope. This is a storm about half the size of Earth. Here's a photo of the new storm (it's the one on the left). From New Scientist: "No one knows for sure what gives the three spots their red color. But one theory is that especially violent storms dredge up material from deeper in Jupiter's atmosphere, such as phosphorus-containing molecules, which undergo chemical reactions that turn them red when exposed to sunlight."

    With a powerful enough laser (more powerful than we currently have, IIRC), it might be possible to lase the area of the Red Spot and perform absorption spectroscopy.

      Fundamentally, one would project a frequency-tunable laser beam onto the Red Spot and read the "reflected" results. The different substances in the target absorb light at very specific frequencies: if a sufficiently powerful laser is used to illuminate the Red Spot (and sufficiently sensitive sensors to read the reflected results), it would be relatively simple to analyze the data and determine the composition of the cloud.

      The big problem is that Jupiter is a long way away--at least 17 light-minutes, IIRC. Jupiter also emits infra-red and radio-frequency EM radiation, which may interfere with the test. And even if we have a powerful enough laser, I'm not sure we have powerful enough sensors to pick out the reflected laser light amidst the reflected sunlight.

  4. earthly parallels to the Spot? by Quadraginta · · Score: 4, Interesting

    It's true that there's not much on Jupiter besides atmosphere, but it's still weird to see what amounts to just a huge cyclone lasting for centuries -- or more -- I suppose we don't have any good idea when the Gred Red Spot first appeared.

    Presumably Earth's atmosphere is just too thin to support weather systems of that longevity, although it's hard to think of a good scaling argument for why the size, thickness, mass et cetera of the atmosphere should dictate the scale of the duration of events in it.

    But I wonder if there are parallels in ocean events, here? We have the El Nino/Nina business, the Atlantic Oscillation, and these things at least have periods near decades. Perhaps some of what we consider "permanent" features of the oceans, like the Gulf Stream, are merely "storms" like Jupiter's Red Spot that last several centuries.

      Um...did you actually read the article to which you point? As opposed to skim? If so, you'll notice that the first recorded observations of the Great Red Spot are, by a strange coincidence, around the time of the invention of the telescope. What does that tell you?

    5. Re:earthly parallels to the Spot? by Quadraginta · · Score: 2, Interesting

      That's because on Earth most storms arise from the interaction of sunlight with the ocean.

      Which, come to think of it, argues that the storms we have in our atmosphere are really just manifestation of energy circulation in the hydrosphere. Maybe the Earth's atmosphere by itself is too small to sustain any significant weather systems at all. Maybe if there were no oceans, there'd be very little weather on the Earth.

      But then again, the experience of Mars suggests otherwise. Mars has no oceans, and can generate enormous and long-lasting storms.

      Back to square one.

      Ok, let's apply a bit of Monty Python logic here: Both Earth and Jupiter are experiencing climate changes. Some believe that Earth's climate change is caused by CO2 emmissions, largely blamed on use of fossil fuels by human beings. Then, we must conclude that humans exist on Jupiter and is causing it's climate change. Therefore, we are not alone! Either that or Al Gore has moved his carbon footprint to Jupiter.

    No, it's known by a great many. It's already been studied, and accounted for, by climatologists. It's discussed frequently with regards to global warming, because increasing solar output combined with increased greenhouse gases makes the problem even worse.

    Why yes we're ready to jump down the throats of peoples whose opinions are conceived in abject ignorance, but who insist on presenting their uneducated ignorant opinions as though it is not only equal to, but superior, to the opinions of those who have done actual science in the field. These are not the same type of opinion. Stop pretending that having this explained to you is somehow a form of censorship or a sign of just how unreasonable everyone else is.
