Це одна з небагатьох комет останніх років, яку можна було побачити неозброєним оком. Її появу трохи зіпсував Місяць

NASA Astronomy Hourly Picture - 2024-10-14: Comet Tsuchinshan-ATLAS Over the Lincoln Memorial
#Astronomy #NASA #Space
Go outside at sunset tonight and see a comet! C/2023 A3 (Tsuchinshan–ATLAS) has become visible in the early evening sky in northern locations to the unaided eye. To see the comet, look west through a sky with a low horizon. If the sky is clear and dark enough, you will not even need binoculars -- the faint tail of the comet should be visible just above the horizon for about an hour. Pictured, Comet Tsuchinshan-ATLAS was captured two nights ago over the Lincoln Memorial monument in Washington, DC, USA. With each passing day at sunset, the comet and its changing tail should be higher and higher in the sky, although exactly how bright and how long its tails will be can only be guessed.

This was my last proper nightscape from way back in July 2024, I did do a half interested one in October with comet A3 tsuchinshan-atlas but only in the back paddock as a single shot opposed to stacked

NASA Astronomy Hourly Picture - 2001-07-16: Animation: Comet Tsuchinshan-ATLAS Tails Prediction
#Astronomy #NASA #Space
Do worlds outside our Solar System have oceans of water like Earth? An indication that such worlds might exist was bolstered recently by new evidence that nearby star system CW Leonis harbors water. Recent observations with the Submillimeter Wave Astronomy Satellite (SWAS) found significant detections of light at specific colors emitted by water. A hypothesis quickly arose that the activity of the central star is vaporizing water from a cloud of comets that surrounds the star -- a cloud that may be similar to the Kuiper Belt of comets that surrounds our own Sun. The above drawing depicts the CW Leonis system with its hypothesized cloud of water-bearing comets situated to a ring. The closest comets are depicted as showing tails rich in water vapor pointing away from the star. Far from the central star, however, comets should not show significant tails and should be more sparsely spaced. The central star, also known as IRC+10216, is an aging giant star located about 500 light-years away toward the constellation of Leo.

Comet Tsuchinshan-ATLAS, photographed mid-October over Italy's Dolomites, already headed back to the outer solar system. Its anti-tail (heavy dust trailing sunward) points opposite the normal tail. NASA APOD.

Comet C/2023 A3 (Tsuchinshan-ATLAS) is a long period comet that passed through the inner solar system in 2023.

The long period comets are thought to originate in the Oort cloud, a cloud of cometary bodies surrounding the solar system upwards of 1 ly from the Sun. #astronomy

Comet C/2026 C1 (Tsuchinshan) remained near mag. 18 before disappearing into solar conjunction. It was still essentially stellar, with its tiny coma below my system's resolution. My last image until November, when it should be slightly brighter. #astronomy #comet

☄️ Comet C/2023 A3 (Tsuchinshan–ATLAS) over Maunakea
🪐 An infrared view of Jupiter by Gemini North
#astronomy
A comet with a long, bright white tail streaks diagonally upward through a starry night sky above a vibrant orange and yellow twilight horizon. In the foreground, dark silhouettes of a volcanic mountain ridge rise above a thick, rolling sea of clouds. An infrared telescope image of Jupiter glowing intensely against a black background, resembling a sphere of molten rock. The planet is covered in highly detailed horizontal bands of fiery orange, yellow, and deep red, revealing complex, churning cloud patterns, spots, and turbulent storms.
