It *is* shrinking (see www.space.com/6386-jupiter...), but it doesn't seem to be going away any time soon as it isn't slowing down. That said, the image above is of a different system that has been dubbed the "brown barge" (see also: www.missionjuno.swri.edu/news/juno-ca...)

Jupiter's Great Red Spot Is Shrinking
The Great Red Spot, a colossal storm twice the diameter of our planet, has been raging for at least 300 years.

Shot of the Sun this lunchtime, 2 December, showing impressive sunspots 4296, 4294 and 4298 coming round. Will they give us an auroral display in the next few days? #Astronomy #Astrophotography
Image of the Sun taken on 2 December 2025 with a DSLR through 150mm telescope and using a solar filter. The sunspots 4296, 4294 and 4298 can be seen at the lower left of the solar disc.

of course lol, never meant to imply that you do, that's my bad i suppose. Felt that some of the strongest offsets on gfs could be a little off, but never meant to cast doubt on your personal written conclusion or forecast themselves—i had no reason to. That's again my bad, could have phrased better.

Gustavo BC @gustavo-bc.bsky.social · 20/09/2025
I imagine you already know, but I'd caution that GFS seems to overshoot highs and lows a *lot*, at least for SAm, sometimes by as much as +5°C That said, other models aren't looking pretty either... and the whiplash from a cold front the very next day is very rough too!

The visible colours are mostly cloud tops, which will be composed largely of liquid droplets and ices (much like our clouds, but with different composition such as ammonia etc). Their shape, though, is determined by the motion of all the gas and stuff in Jupiter's atmosphere, so yes, in a way

This is a real image of what a new solar system looks like. The light from the central star is blocked, so it's possible to see the lanes of cleared-up dust around it. And that small, yellowish blob at lower right? That's a whole, brand new planet.

++em que as redes usam sistemas que já existem, com verificação facial por "IA" ou com verificação de documento, fornecidos por empresas de procedência suspeita. Isso sem contar alguns outros pequenos problemas que surgem da falta de clareza em alguns pontos, como também aconteceu no RU e outros.

como já disse, as redes têm que ser responsabilizadas por deixar abuso correr solto, mas vigilância em massa não é o jeito certo. A esquerda online brasileira tem muito que aprender que "proteger as crianças" é desculpa velha de político que não tem nenhum interesse em realmente proteger ninguém.

as redes tem que ser responsabilizadas, sim, mas o texto do projeto já diz que contas com "indícios" de serem "operadas por crianças" terão que ter identidade verificada, incluindo por documento pessoal, e isso tem muito jeito de virar vigilância em massa e pouco jeito de proteger alguém

Here's the quarter Moon from about a week ago. You can juuust see the Lunar X near the top left, and the Lunar V near the top middle — these are a light-and-shadow effect created by the rims of a few craters near the terminator for just a few hours every first quarter #astrophotography
The waxing quarter Moon of Wednesday, 2025-07-02. The colours are gently enhanced to show the subtle colour differences that exist on the Moon's surface due to varying mineral composition. Near the terminator, both the Lunar X and lunar Y light-and-shadow effects are visible.Cropped view of the previous image, zoomed into the area containing the previously mentioned Lunar X and Lunar V, which are circled and labelled. The X is formed from the rims of the craters Blanchinus, La Caille, and Purbach, while the V is formed from the rim of the Ukert crater plus a few small craters that surround it.

at this scale the Earth is like 5 pixels. a microscopic speck. a tiny little thing. almost every single one of these spots is bigger. 🤯 🔭
zoomed in view of the previous image, cropped to an area that covers most of the spots. A tiny circle shows the Earth to scale, with a label and an arrow pointing to it that says "EARTH". This tiny circle, containing everyone you know and everywhere you've been, is smaller than almost every single sunspot visible.

Trying solar photography again, there's some nice active regions right in the middle! AR 4100 is just below centre, and AR 4099 is just above and to the left. AR4100 produced a huge flare earlier that should light up the auroras in the coming nights! #astrophotography 🔭
Photo of the Sun, seen as a white orb with a gentle texture to it and various spots. Active Region (AR) 4100 is visible just below the centre of the disk with 26 spots, and AR 4099 is just above and to the left of centre with 13 spots.
ARs 4096 (bottom left), 4101 (left of 4100), and 4104 (above+right of 4100) are also visible, with 1-3 spots each.
North is approximately down.
