Cassini Observes Hurricane-Like Storm On Saturn 69

Posted by Zonk
from the go-go-little-spacebuggy dept.
Aglassis writes "The Cassini spacecraft recently observed a hurricane-like storm on the south pole of Saturn. What makes this storm particularly interesting is that this is the first time that a clearly defined eyewall has been seen outside of the Earth in the Solar System. Neither the Great White Spot of Saturn nor the Great Red Spot of Jupiter have had an observable eyewall. NASA, JPL, and the Space Science Institute have released a short movie of the motion around the eyewall (mirrored at YouTube)."

              Gosh, this is so stupid... why are you so offended that I replied to your message? Holy Crap. You made a reference to Katrina, Global Warming alarmists blamed global warming for Katrina, the whether on Saturn is apparently getting worse (see my quote), so it must be global warming. What's your problem? Do I need to make a chart?

    For you folks that actually get up when it is still dark, Saturn is really nice this season:

    Saturn (magnitude +0.5, in Leo), rises around 11:30 or midnight and is in fine view high in the southeast by early dawn. Regulus, about half as bright, sparkles 5 below Saturn after they rise. By dawn Regulus is to Saturn's lower left.

    • I just saw this on Jack Horkenheimer (Star hustler) on pbs. For 5 minutes a week, this show has a lot of cool stuff. I'm glad I have a dvr. I remember watching this when I was 5-10 or so.

      He gives very good tips for how to identify different starts, where to find them, what's going on, etc.

    For those interested, unmannedspaceflight has active discussions on well.. unmanned space [unmannedspaceflight.com] flight, and in particular, this mission. Cassini is another successful unmanned mission. Space is really starting to get exciting again.

      "...starting to get exciting again"? Since Galileo arrived at Jupiter more than a decade ago and there has hardly been a lull in flagship-class missions (let alone missions to Mars, comets, asteroids, Venus, etc.) since then, I tend to feel that we're well past the start :)

        You're right. Maybe I'm just starting to pay attention. Let's hope that others follow suit (I think the Internet really helps), which would only be good for humanity.

      Unmannedspaceflight is a fantastic site. Anyone interested in the topic will also want to check out Riding with Robots [ridingwithrobots.org], which offers free widgets and screen savers that download the latest probe imagery.

  • This image and its' writeup on the Cassini Website says this hurricane cut 20-45 miles through Saturn's cloud cover. The Cassini Team was able to calculate this figure from the way the Sun's shadow deepened on the 3 hour (14 frames) image.

    My questions are:
            1) how thick was the remaining cloud layer, and
            2) would it be possible to get a view of Saturn's surface?

      Saturn is mostly gas; the planet as a whole is considerably less dense than water. There isn't really any solid surface to speak of; we generally consider the cloud tops to be the surface for all intents and purposes.

      Somewhere way, way down there, there may be a solid surface of metallic hydrogen, or possibly crystalline carbon, and perhaps inside that a rocky core somewhat larger

        If you look at the atmospherics of terrestrial hurricanes, they are the source of low barometric pressures. Since the cloud material on Saturn is so much denser, it follows that the atmospheric pressure are alleviated in these "hurricanes". It would be worth 5 years of my life to find out by how much - perhaps some Fluid Dynamics researcher may consider modeling this scenario.
  • Not to go ruining perfectly wonderful Bush/Katrina/goatse discussions by talking about science, but I thought I'd point out why this is actually really interesting to a lot of people outside of NASA. There are a large subset of people studying the atmospheres of Jupiter and Saturn because they provide really nice examples of atmospheric processes on Earth under more "ideal" circumstances. The typical storm on Jupiter or Saturn behaves much more similarly to a mid-latitude storm on Earth from a fluid mecha
  • Seriously, if you have hardware that is working fine with Windows XP or Win 2k3 Server, what possible reason do you have for taking a risky manuver like the Vista "upgrade"? A saner "migration plan" is to use the machine as is till it fails.

    Contrary to what Microsoft wants you to believe, if your machine functions today it suddenly will not "suck" the day Vista comes out. Stay with what works *now* instead of doing untested upgrades.
