Webb takes another infrared image of Uranus

Astronomers have used the Webb Space Telescope to take another infrared image of Uranus, following up on earlier observations with Webb in April.
The new false-color infrared picture is to the right, cropped, reduced, and enhanced to post here. Though the close-up of Uranus is in the left corner, the overall view is somewhat wider than the image I highlighted previously, showing many background galaxies and at least one star. The star is the spiked bright object on the left. In false color the galaxies all been given an orange tint, while the blue objects near Uranus are its moons. Because Uranus’s rotational tilt is so extreme, 98 degrees compared to Earth’s 23 degrees, its north pole is presently facing the Sun directly, and is in the center here.
One of the most striking of these is the planet’s seasonal north polar cloud cap. Compared to the Webb image from earlier this year, some details of the cap are easier to see in these newer images. These include the bright, white, inner cap and the dark lane in the bottom of the polar cap, toward the lower latitudes. Several bright storms can also be seen near and below the southern border of the polar cap. The number of these storms, and how frequently and where they appear in Uranus’s atmosphere, might be due to a combination of seasonal and meteorological effects.
The polar cap appears to become more prominent when the planet’s pole begins to point toward the Sun, as it approaches solstice and receives more sunlight. Uranus reaches its next solstice in 2028, and astronomers are eager to watch any possible changes in the structure of these features. Webb will help disentangle the seasonal and meteorological effects that influence Uranus’s storms, which is critical to help astronomers understand the planet’s complex atmosphere.
If you want to see what Uranus looks like to our eyes, check out the Hubble pictures taken in 2014 and 2022. Though fewer features are visible in optical wavelengths, those two images showed long term seasonal changes.
Webb has now revealed some shorter term changes.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuse to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

I have always had the ability to see the absurdity in nearly everything and that headline just SCREAMS for absurd remarks! My first thought was “oh, that explains that burning sensation I had recently”! Another was “didn’t Senator Ben ‘Dover’ Cardin’s aide upload that already”?? I’m sorry, I know this is a serious subject, but you have to admit, Uranus is just a funny name!
