On October 2, 2024 (Hawai‘i Standard Time), Comet Tsuchinshan-ATLAS appeared in the eastern sky. From Maunakea in the early morning, its long tail stretched across the vivid dawn sky, illuminated by the colors of sunrise. Five telescopes of the Maunakea Observatory are captured in this picture.

On 11 Nov. 2020, APOD published this spectacular image. It is a spiral mosaic of 48 full moons, collected over 10 years from northern to southern Italy. No trick: it is the Moon, filtered by Earth’s atmosphere. Credit: Marcella Giulia Pace apod.nasa.gov/apod/ap20111... 🔭⚛️🧪 #astrophotography

Forty-eight full-Moon photos. Black background. They form a spiral, and the rings get tighter toward the middle. Some appear gray, some brownish gray. Others appear yellow, orange or deep red. A few pale blues. One vivid purple Moon sits near the center.
Several disks low in the arrangement look slightly flattened rather than round. The sequence ends with a faint red Moon from the total lunar eclipse of 27 July 2018.

Enigmatic flashes of x-rays in the sky may come from the catastrophic merger of two stars, creating an ultra-dense and ultra-magnetc remnant called a magnetar. The finding come from another kind of merger, one of Chinese & EU science missions. 🧪🔭 www.sciencedaily.com/releases/202...

Think you know Jupiter? In ultraviolet light, it can look like almost another planet. Dark poles, a dark Great Red Spot, one bright oval that fades. #Hubble reveals clouds and hazes the eye cannot see. 📷NASA, ESA, Hubble, Judy Schmidt apod.nasa.gov/apod/ap18101... 🧪🔭⚛️ #planetsci #astronomy

Jupiter sits big and round against black. This is near-ultraviolet, false color.
Bands run across the disk in cyan, pink and muted brown instead of the usual cream and orange. The poles look darker brown with slightly pinkish clues. On the left side of the planet a large storm, the Great Red Spot, is also dark rather than red. Just to its right a smaller oval that would look white in visible light is similarly dark. Farther right a chain of storms, the String of Pearls, stands out bright pink.A small round disk at upper left, off the planet’s limb, is Ganymede.

This is a SMALL version of the largest JWST image released so far—of IC 348, a star-forming region about 1,000 lightyears away. Open up the image and marvel in the incredible beauty even in our galactic neighbourhood. This is what it looks like when stars are born.

From the source: "A star-forming region. It is blanketed in thick clouds of gas and dust, millions of kilometres across, that form swirling patterns. Bright stars are scattered throughout the clouds, with the densest cluster situated in the centre of the scene. Each is crowned with six long points created by the optics of the telescope’s mirrors. In the upper right, a couple of hidden stars blast out long, glowing jets of material."

This is a stunning lunar corona, visible in Death Valley. A corona is an optical phenomenon you may see when thin clouds partially veil the Sun or the Moon. Photo: Arpan Das Source: epod.usra.edu/blog/2021/08... 🔭🧪⚛️ #sciart #science #optics

A night landscape in Death Valley. In the foreground the playa is dry and cracked. The ground is broken into blue-grey plates of mud or salt, divided by dark fissures. Near the bottom center one crack forms a wide, almost round shape, like a plate that has split. Some of those surfaces pick up a faint gloss from the moonlight.A dark mountain range sits farther back, low and uneven against the sky. The Moon is high and very bright. The disk is overexposed, almost a white glare. A lunar corona surrounds it. First comes a bright aureole. Outside that the colour changes. Near the Moon it is bluish-white. Then green. Then yellow. At the edge there is a faint pink-violet rim. The rings stay soft and run into one another.
Thin, streaky clouds drift across the sky, partly veiling the Moon and helping form the corona. The night sky offers a magical view. The whole scene is cast in cool blue tones, quiet and wide.

Principale conclusion : le mouvement des aérosols est dominé par la dynamique de l'air générée par la chasse, et pas simplement par la projection balistique de gouttelettes. L'article rappelle aussi qu'un couvercle fermé réduit la dispersion des aérosols, mais ne la supprime pas nécessairement.
