A bit of #Jupiter (NASA / JPL-Caltech / SwRI / MSSS / Arndt Stelter)
Taken high above Jupiter's southern subtropics, this picture shows various of its cloud bands with numerous storms and swirls and very distinct colour patterns, the area closest to the south pole being notably bluer than the rest.

La Terre vient d’enfanter ce qu’elle sait faire de pire. Depuis les satellites, on a probablement sous les yeux l’une des pires catastrophes météorologiques modernes.

Alors que TotalEnergies a été condamné jeudi pour s’être présenté comme un "acteur majeur de la transition énergétique", des ONG révèlent que la multinationale est depuis 2021 l'industriel engagé dans le plus grand nombre de projets fossiles au monde (154 au total 😮) .

Managed to grab a few more images of Comet Lemmon this evening (Sunday Oct 26th) from Kielder Campsite, Northumberland, through very brief gaps in the clouds. This is a phone-processed stack of half a dozen jpg images taken with my Seestar S50.

NASA's Perseverance rover has seen multiple signs of mineral formations linked to biological activity, providing strong hints that life once existed on Mars - but plans to confirm the find are under threat by budget cuts to NASA.

An extravagantly colored spiral galaxy. Red, orange, dusty arms of infrared light blend together in one splotchy, swirling mess. Bright patches of speckled star formation dot the arms all over, some tiny and some large and complex. Soft, blue x-ray light is seen along a diagonal axis from the upper left to lower right, along with some small fuzzy dots speckling the image in seemingly unrelated ways. The center is bright white with relatively smaller magenta colored jets along the same diagonal axis.

#NASAWebb’s new look at planetary nebula NGC 6072 resembles a squished bug, with multiple outflows extending from the central dying star: webbtelescope.pub/4f5R5s5 🔭 🧪
Colorful, mostly red glowing cloud with a distorted, asymmetrical shape that is illuminated from within by a bright central star. The asymmetrical shape resembles a large squished bug on the ground. In the center, a light blue glow appears over areas of dark pockets that look dark blue and are traced with orange material. It has a clumpy appearance. Shells of gas and dust appear as lobes stretching from roughly 11 to 5 o’clock, another from 1 to 7 o’clock, and possibly a third from 12 to 6 o’clock. The shells become a deeper red with distance from the center. These outflows push gas toward the equatorial plane, forming a disk that appears to span from 9 to 3 o’clock. The background of space is black and speckled with tiny bright stars and distant galaxies.

Just released: NEW images of Phobos over Mars by @esa.int Mars Express 🔭🧪

This view shows Phobos above Olympus Mons!

Full-size (130MP) image & details: flic.kr/p/2rggHKy

Captured on May 14, 2025 | Image ID: HQ967
Raw data from: psa.esa.int
A high-resolution color image of Mars with the small, dark, potato shaped satellite Phobos, seen in sharp contrast as it passes over the massive volcano Olympus Mons. Phobos appears irregular and shadowed against the softly rust colored Martian surface. In the distance, two other volcanic features Ascraeus Mons (upper right) and the flatter Alba Mons (upper left) are visible. Wisps of light clouds and the blackness of space frame the planet’s curved horizon.

Le 10 mai dernier, au sol 1500, Perseverance se prenait en selfie près du site de forage "Bell Island". Le rover se situe en contrebas de l'affleurement Sally's Cove, en haut à droite de l'image. On remarque que le forage a extrait de la poussière grise. Inspectons de plus près Perseverance...

🤩 The MIRI instrument on the NASA/ESA/CSA James Webb Space Telescope has captured a dying star’s display in unprecedented detail.

Read more 👉 www.esa.int/ESA_Multimed...

🔭 🧪
What looks like a single large, bright star (but is two) shines with bright purple diffraction spikes at the center of a large, diffuse cylinder of gas and dust that is tipped to the right. At the center is a bright pink clumpy cloud that takes up about 25% of the view. There are two large rings seen at a roughly 60-degree angle that appear joined at top left and bottom right. The edges are denser, and form shallow V-shapes that go inward. The rings appear orange at top left and bottom right, and are blue at bottom and center right. There is diffuse orange material around the body. The black background of space is speckled with tiny stars and galaxies mostly in blues and yellows. Areas Webb did not observe are along the top edges, a thin vertical near the nebula at top left, and at the bottom left and right corners.

🆕 This new #Hubble Space Telescope image of NGC 346 kicks off celebrations for the upcoming #Hubble35 anniversary – the first in a series revisiting previous Hubble targets, combining new processing techniques with the latest data 🧪🔭

A star cluster within a nebula. The background is filled with thin, pale blue clouds. Parts are thicker and pinker in colour. The cluster is made up of bright blue stars that illuminate the nebula around them. Large arcs of dense dust curve around, before and behind the clustered stars, pressed together by the stars’ radiation. Behind the clouds of the nebula can be seen large numbers of orange stars.

BOOM! What a beautiful #SolarFlare (just now). This eruptive event reached the X-class level, and produced this stunning coronal mass ejection. The flare source region will rotate to face Earth in the coming week. Further strong solar activity is likely! #spaceweather

📷 This NASA/ESA #Hubble Space Telescope image shows a small region of the Small Magellanic Cloud focusing on the centre of star cluster NGC 346. The Small Magellanic Cloud is a 'dwarf galaxy' and one of the closest galaxies to our Milky Way galaxy 🧪🔭

An area of space that is filled with stars. Most of the stars are small, distant dots in orange colours; closer stars shine with a bright glow and four thin spikes around them. These closer stars appear in both bluish and reddish colours. Clouds from a nebula cover the left half of the scene, giving it a blue-greenish cast. More pieces of cloud drift over the black background of space on the right.
