APOD: North North Temperate Zone Little... (2017 Aug 04)

Postby APOD Robot » Fri Aug 04, 2017 4:10 am

Image North North Temperate Zone Little Red Spot

Explanation: On July 11, the Juno spacecraft once again swung near the turbulent Jovian cloud tops. On its seventh orbital closest approach this perijove passage brought Juno within 3,500 kilometers of the Solar System's largest planetary atmosphere. Near perijove the rotating JunoCam was able to record this stunning, clear view of one of Jupiter's signature vortices. About 8,000 kilometers in diameter, the anticyclonic storm system was spotted in Jupiter's North North Temperate Zone in the 1990s. That makes it about half the size of an older and better known Jovian anticyclone, the Great Red Spot, but only a little smaller than planet Earth. At times taking on reddish hues, the enormous storm system is fondly known as a North North Temperate Zone Little Red Spot.

in this stunning view, in the lower right area, it seems that a smaller area appear trasparent, reavealing something whitish underneath, with a red bar over it... OF COURSE it's another cloud top, maybe a bit deeper than the clouds around, but it appears, to me...

With all these storms i would expect to see lighting, is camera not sensitve enough to spot it? would Jupiter create red sprites like we see with earth storms?

Jupiter and mini Jupiter? No, Rick and Brett Lee.

To me, that red-and-white striped round thing looks like a mini Jupiter, inside the cloud tops of Jupiter! :wink:

Wouldn't it be fun to parachute into Jupiter? You might pass through a reasonable temperature, reasonable density, region before the end. It would not be fun at all to parachute into Venus!

What is amazing is the scale of this storm. 8 thousand kilometers? The Earth could easily fit inside of it. And imagine how high those clouds must be - at least a hundred kilometers.
They're all wasted!

An anticyclonic storm system was indeed spotted in Jupiter's North North Temperate Zone in the 1990s

<<As well as the Great Red Spot, Jupiter sometimes presents one or more Little Red Spots (LRSs) in various latitudes. An LRS is often seen in the North North Temperate Zone (NNTZ), but the frequency and properties of these ovals have never been studied in detail. Here we review all our records of the red, white, and methane-bright anticyclonic ovals in the NNTZ. There is a simple conclusion: A single LRS, which we name NN-LRS-1, has persisted from 1993 to 2009. It has varied in colour between red and off-white, but has been methane-bright throughout these years. This now ranks among the most long-lived spots ever recorded on the planet. There is always at least one other oval in this latitude. This was a second methane-bright LRS from 1994-1997, and there was also a smaller LRS in 2006. The other ovals are all white; two have lasted for four years or more and were sometimes methane-bright; others have had shorter lives and were not. These results suggest that red colour, and the high-level haze that accompanies it, are correlated with the size and longevity of the oval. All these ovals have variable speeds, alternating irregularly between slow (~ 1°/month in System II longitude) and fast (~ 12°/month). The latitudes of the ovals range from 40 to 41.5°N, and correlate closely with their instantaneous speeds. However the larger, longer-lived ovals (especially the LRS) are centred systematically further south than the smaller white ovals, because they distort the retrograding jetstream more deeply. Similar behaviour in other domains on the planet explains how ovals of different sizes move with a single slow current while also being sensitive to the zonal speed gradient. An oval at 60°S shows very similar behaviour and has probably existed since 1994 or earlier.>>

The Earth could NOT easily fit inside of it. At 8,000 km it is roughly 2/3 the size of Earth. The Earth is 12,750 km in diameter. That is not just a little smaller than Earth either.

Lightning on Jupiter occurs in convective storms similar to those on Earth. That's not what we're seeing in this image, so there may not even be any lightning here. Also, on Jupiter the lightning is always cloud-to-cloud, so we don't see the bolts directly, just the light the produce scattered inside clouds. Such lightning is not going to show up in images of sunlit clouds, no matter how sensitive the camera. All of our images of lightning on Jupiter were made on the night side.

Today's APOD is of the 23+ year old South TZ LRS

I'm not sure why you think this, but judging by where the metadata for the image must have come from within the Perijove 07 datastream, I would say this is in the Northern Hemisphere not the Southern.

    Indeed. I got confused. :roll:

<<A dynamic storm at the southern edge of Jupiter’s northern polar region dominates this Jovian cloudscape, courtesy of NASA’s Juno spacecraft.

This storm is a long-lived anticyclonic oval named North North Temperate Little Red Spot 1 (NN-LRS-1); it has been tracked at least since 1993, and may be older still. An anticyclone is a weather phenomenon where winds around the storm flow in the direction opposite to that of the flow around a region of low pressure. It is the third largest anticyclonic oval on the planet, typically around 3,700 miles (6,000 kilometers) long. The color varies between red and off-white (as it is now), but this JunoCam image shows that it still has a pale reddish core within the radius of maximum wind speeds.

Citizen scientists Gerald Eichstädt and Seán Doran processed this image using data from the JunoCam imager. The image has been rotated so that the top of the image is actually the equatorial regions while the bottom of the image is of the northern polar regions of the planet.

The image was taken on July 10, 2017 at 6:42 p.m. PDT (9:42 p.m. EDT), as the Juno spacecraft performed its seventh close flyby of Jupiter. At the time the image was taken, the spacecraft was about 7,111 miles (11,444 kilometers) from the tops of the clouds of the planet at a latitude of 44.5 degrees.>>

For real though, that sure looks like it's something. I'm not saying it's the Death Star, but it looks like something.

Are these Jovian "storms" caused by temperature? What contributes to their longevity, perhaps their sheer size? Do they ever have eyes like earth's hurricanes? How can we see those dark side lightning images?

Why is there a death star hiding on Jupiter?

So far it's been a great place to hide. up until now there haven't been any low flying satellites that could spot it. And there won't be for much longer, either.

<<Worlds in Collision is a book written by Immanuel Velikovsky (10 June 1895 – 17 November 1979) and first published April 3, 1950. The book postulated that around the 15th century BCE, Venus was ejected from Jupiter as a comet or comet-like object, and passed near Earth. The object changed Earth's orbit and axis, causing innumerable catastrophes that were mentioned in early mythologies and religions around the world. Fifty-two years later, it passed close by again, stopping the Earth's rotation for a while and causing more catastrophes.>>
