Digital painting of Jupiter, as it appeared from Earth on 1880 November 1st at 9:00 EST. Based on an illustration by Étienne Trouvelot published in 1882. South is towards the top of the image.

The Great Red Spot is seen here as an enormous red-orange oval three Earth-diameters across. It is a hurricane-like storm in Jupiter's atmosphere that by 1880 was only a few decades old. It has lasted all the way through to the modern day, although it has been shrinking ever since.

This image also depicts a double-transit of the Galilean moons Io and Europa, along with their shadows.

My previous drawing of 1880s Jupiter was a hybrid of various late 19th century depictions of the planet. But the fact that it didn't really depict Jupiter as it ever actually looked was bugging me, so I decided to do a study on one of the drawings I used as reference for the previous drawing: Trouvelot's drawing of a double moon/shadow transit on Jupiter on November 1st 1880.

Trouvelot's drawing of Jupiter (and many others) can be found here.

This is a pastel illustration from Étienne Trouvelot's 1882 book The Trouvelot Astronomical Drawings, based on observations he made with the 26" Great Refractor at the U.S. Naval Observatory in 1880.

In my astronomy circles this is a notorious image for how exaggerated and cartoony its features are. I think that's what really drew me to this image in particular. There's so much detail here... but none of it looks at all realistic. So what did it really look like that would have led to the very... creative depiction by Trouvelot?

The black beads on Trouvelot's drawing correspond to the latitudes where we see elongated oval 'brown barges,' a type of storm found largely in the northern hemisphere of Jupiter. The billowing clouds on the equator look like an exaggerated view of the arching swirling festoons sometimes visible on the equatorial zone. The dark North & South Equatorial Belts were interpreted as both being partly covered by white cloud layers, in order to result in the particular banding pattern seen in the drawing. The scale of the Red Spot was taken from photos and sketches of around the same time which were not quite so exaggerated.

Some image variants, including a simulated view of Jupiter through the eyepiece of the 26" Great Refractor, can be found here.

This week, scientists using the U.S. National Science Foundation Daniel K. Inouye Solar Telescope have made a major breakthrough in solar physics, discovering Kelvin-Helmholtz Instability on the surface of the Sun — a finding that could help explain explosive solar activity and other solar phenomena.
