Starry Stormy Night

I don't usually post others' work, but I sort of collaborated:

StormyStarry Night

Notice anything unusual about the sky?

The sky is not filled with van Gogh's stars, but rather swirling storm clouds on jupiter's north pole captured by the juno mission.  The foreground is my daughter's rendition of van Gogh's Starry Night.  After seeing this awesome flyby of jupiter captured by the Juno space craft, my brother commented that the clouds were reminiscent of Starry Night.  So I took a picture of my daughter's painting, a screen shot of the NASA flyby and combined the two in photoshop.  

Here's her original a la van Gogh:

and here's the flyby paying homage to kubric (suggest full screen view):

Ice Giants and Moons

Here's a capture of Uranus equatorial north (earth's) up:

Uranus

Uranus' north pole is rotated to the left 90 degrees relative to the orientation of the rest of the planets in the solar system. a cloud on the north pole makes the left side brighter.  

Here's a wider view using a much longer exposure showing...

the moons of Uranus
Miranda is above, but lost in the glare as it's too close

Here's Neptune:

Neptune 11/29/21 4:04 UTC

and a brighter view showing Triton:

The magnetic fields of the ice giants uranus and neptune are unusual in that, they are highly skewed/off center from the axis of rotation.  a recent study suggest this is due to super ionic ice (which is just fun to say).

animated jupiter

seeing was not great for me this past apparition of jupiter.  here's an animation at low power:

Jupiter 10/4/21 03:34-03:47-UTC

Here's a combination of all of the frames derotated combined.  this gives a smoother image, but blurs the moon and causes edge effects at the extremes:

Lastly here's a wider composite image showing the moons:
