APOD: Jupiter Rotates (2021 Oct 26)

[APOD Robot]

Jupiter Rotates

Explanation: Observe the graceful twirl of our Solar System's largest planet. Many interesting features of Jupiter's enigmatic atmosphere, including dark belts and light zones, can be followed in detail. A careful inspection will reveal that different cloud layers rotate at slightly different speeds. The famous Great Red Spot is not visible at first -- but soon rotates into view. Other smaller storm systems occasionally appear. As large as Jupiter is, it rotates in only 10 hours. Our small Earth, by comparison, takes 24 hours to complete a spin cycle. The featured high-resolution time-lapse video was captured over five nights earlier this month by a mid-sized telescope on an apartment balcony in Paris, France. Since hydrogen and helium gas are colorless, and those elements compose most of Jupiter's expansive atmosphere, what trace elements create the observed colors of Jupiter's clouds remains a topic of research.

No hexagon at pole or unknown region for now, never shooted.

Hostile but pretty planet! 10 hr spin cycle, amazing!

Jupiter's colors!

Angry Kitty!

"The featured high-resolution time-lapse video was captured over five nights earlier this month by a mid-sized telescope on an apartment balcony in Paris, France." How did somebody on Earth get a view from above Jupiter's pole?

[Iksarfighter]

I was meaning in Jupiter imagery generally, did they spot an hexagon at poles ?
Maybe never passed by ?

They either relocated to a higher balcony...
or simply remapped their digital data.

There are polygonal cyclones within a few degrees latitude of Jupiter's poles

...but they wouldn't be visible from Earth.

Paris has a day night cycle (not to mention Jupiter rising and setting)... How did they get five days of images without being interrupted?

Five hours of a single night is sufficient to observe all of Jupiter.

Yes, you can see it all in 5 hours, nominally half a Jovian rotation (ignoring limb foreshortening and the terminator-darkened edge along the eastern limb now), but you would still need the full 10 hour rotation period (more exactly, 9 hr 55.5 min) to see all of the surface features make a complete pass across the face of Jupiter visible to earth. In any case, the base images for this APOD were likely captured during a few hours each night, not continuously over five days, then skillfully combined into this animation.

i wonder what it smell like

[UncleJeff]

Try as I might, I can't detect any relative movement among the features in Jupiter's atmosphere. I guess Jupiter's weather moves much more slowly than its rotation. On the time scale of the video, the weather features look static.

[johnnydeep]

Two comments: I'm surprised that a telescope in a large city like Paris is able to get such a clear view of Jupiter. And as for determining the trace elements that determine the differences in cloud colors, why wouldn't "simple" spectra provide the answers?

Thanks to Juno you might be able to wear it soon.

I'm figuring that they took ~30 hours of rapid images over a ~100 hour period and threw out all the cloudy/turbulent images.

Reordering, averaging & smoothing left the slow moving features (zones, belts & vortices) more or less in place whereas rapidly moving features (up to ~150m/s [or 54,000km/100hrs] just got "shmeared" out.

Atmospheric motions over ~240 hours

This 14-frame animation spans 24 Jovian days, or about 10 Earth days. Zones, belts and vortices on Jupiter. The wide equatorial zone is visible in the center surrounded by two dark equatorial belts (SEB and NEB). The large grayish-blue irregular "hot spots" at the northern edge of the white Equatorial Zone change over the course of time as they march eastward across the planet. The Great Red Spot is at the southern margin of the SEB. Strings of small storms rotate around northern-hemisphere ovals. Small, very bright features, possible lightning storms, appear quickly and randomly in turbulent regions. The smallest features visible at the equator are about 600 kilometers across. The occasional black spots in the image are moons of Jupiter getting into the field of view.

In today's APOD (10/26/21), is a movie of Jupiter rotating. Just off of center at the start of the video is a straight black line going from pole to pole. One of my 9yr old students noticed it. I at first thought it was produced by the lens, but then I noticed that the line rotated with the planet. Can you take a minute and watch it, and then maybe let me know what we're seeing?

Hi, I watched the video part you are referring to several times but I never saw the line. Try reloading I would guess that it is a streaming artifact unrelated to the video.
Cool to note, nine was about the age I really got in to astronomy, thank you Patrick Moore and “ Observer's Book of Astronomy”!
Happy observing!

"The featured high-resolution time-lapse video was captured over five nights earlier this month by a mid-sized telescope on an apartment balcony in Paris, France." How did somebody on Earth get a view from above Jupiter's pole?

He might have digitally draped the video of the clouds onto a sphere then rendered them how they would look from above.
During Apollo they did this manually by projecting full moon shots onto a big globe so they could see what the poles looked like.

A line seems to be there. I think he's referring to this one, seen here at 10 seconds in:

Straight Line In Jupiter's Clouds?

[jldauvergne]

Hi, you are right, a line is visible on the planet. I've tryed to avoid it without success. I don't realy know why does le software add this when it create the animation but it corresponds to the logitude 0° of the global map that I've made before producing the video.


It's not a black line left when I've croped. I've checked that.

Ok, so it's just a "stitching artifact".

A one-way ticket. A cash-stuffed teddy bear. A dream decades in the making.
For Katalin Kariko, a life in full: Awe-inspiring ideas, careful experiments,
unnoticed successes and the repeated sting of rejection
By Carolyn Y. Johnson, The Washington Post, October 1, 2021

<<In 1985, the Hungarian lab where [biochemist Katalin] Karikó worked lost its funding. She looked for an opportunity in the United States, settling on a postdoctoral position at Temple University in Philadelphia. The family bought one-way tickets and sold their car, smuggling the money inside a big brown teddy bear with red-rimmed eyes. A seam runs down its back, where Kariko performed the surgery. She keeps it in her daughter’s childhood room to this day.>>

<<Katalin Karikó (Hungarian: Karikó Katalin; born 17 January 1955) is a Hungarian biochemist who specializes in the development of in vitro-transcribed mRNA for protein therapies. Together with American immunologist Drew Weissman, she holds U.S. patents for the application of non-immunogenic, nucleoside-modified RNA. This technology has been licensed by BioNTech and Moderna to develop their protein replacement technologies but was also used for their COVID-19 vaccines.

Karikó grew up in Kisújszállás, Hungary, in a small home without running water, a refrigerator, or television. Her father was a butcher and her mother was a bookkeeper. She excelled in science during her primary education. After earning her Ph.D. at the University of Szeged, Karikó continued her research and postdoctoral studies at the Institute of Biochemistry, Biological Research Centre of Hungary. In 1985, the lab lost its funding, and she left Hungary for the United States with her husband and 2-year daughter. They smuggled in a teddy bear £900 received on the black market in exchange for the proceeds from selling a car.>>
