A rare photograph showing Comet Leonard’s gas tail as it passes by Earth for its only ever appearance has been announced as the winner of the latest Astronomy Photographer of the Year Competition.
The image, titledDisconnection Event, was taken by Gerald Rhemann and shows the tail of a comet being torn away by a powerful solar wind.
“Astronomy, myth and art come together beautifully in this shot. It holds great value to scientists, as it elegantly captures a disconnection event,” said Imad Ahmed, a member of the judging panel of this year’s competition, and director of the New Crescent Society.
“Yet this photograph, which was taken on Christmas Day, seems to tell an otherworldly story too – it could be the Star of Bethlehem, an angel or a fairy soaring through the night sky.”
The Young Astronomy Photographer of the Year award was won by two fourteen-year-old boys from China. Yang Hanwen and Zhou Zezhen collaborated to capture Andromeda Galaxy: The Neighbour, a photograph of one of the Milky Way’s closest and largest neighbours.
The winning image will be on display alongside the winners of the other categories in the accompanying exhibition, opening at theNational Maritime Museumin London, UK, on 17 September 2022.
Overall winner
Comet Leonard was discovered by G J Leonard on 3 January 2021. It made its closest pass on 12 December 2021, and having left the Solar System, won’t be seen from Earth again. On 25 December 2021, a dramatic tail disconnection event happened. A piece of Comet Leonard’s tail was pinched off and carried away by the solar wind, as can be seen in this dramatic image.

Winner - Our Sun category
An image of the Sun, combined from images taken every day between 25 December 2020 and 31 December 2021 (missing just 6 days during this period). After a year, the images were blended to create a single shot. The sunspots create two bands on the solar disc, around 15–35 degrees north and south of the equator and gradually start drifting towards it (a phenomenon known as Spörer’s law).

Winner - Stars and nebulae
This ultra-deep exposure of the ‘Eye of God' (also known as the Helix Nebula, or NGC 7293), reveals the glorious colours of the core and rarely seen surrounding details. Photographed at Chilescope, Río Hurtado, Coquimbo Region, Chile, on 8 August 2021. Photo by Weitang Liang/APOTY
Winner - People and space category
This image features the International Space Station (ISS) positioned directly over the Apollo 11 Moon-landing site on the Sea of Tranquility. The moment only lasted milliseconds and required precise positioning to capture the pass at the perfect time. Photographed in Florence, Arizona, USA, on 19 January 2022.

Winner - Young astronomer of the year
The Andromeda Galaxy, or Messier 31, is one of the closest and largest neighbours of the Milky Way. M31 is also the most distant object the human eye can see. When you look at it with the naked eye it’s like a fog, but through the telescope it shows its magnificence. Photographed inHeishicheng, Kangding, Sichuan, China, on 21 February 2021.

Winner - The Annie Maunder prize for digital innovation
Multiple images of the Sun from the first part of the Solar Cycle have been layered to create concentric rings in this unusual and original composition. The oldest ring lies in the centre while the most recent sits furthest away. Month by month, the rings grow like the rings of a tree. The overall image is a marking of the passing of time, which incorporates visual evidence of increasing levels of solar activity apparent in the dark markings of solar flares.Photo by Pauline Woolley/Solar Dynamic Observatory/APOTY
Winner - The Patrick Moore prize for best newcomer

Winner - Our Moon category
Once a month the Sun rises over the giant lunar crater Plato and casts huge shadows from its east rim across its lava-filled floor. Occasionally this event coincides with a night of good visibility. The night of 20 April 2021 was one such rare night, with steady skies and the Moon high overhead, the dark, projected rim-profile was visible in exquisite detail.

Winner - Skyscapes category
Namcha Barwa is one of the most beautiful snow-capped mountains in China. The name of the mountain in Tibetan means ‘spear thrusting into the sky’. This untouched land is also home to the purest of starry skies, the trails of which weave a wide net even on full Moon days. Photographed inNyingchi, Tibet, China, on 24 December 2021.

Winner - Galaxies category
This image shows the faint star streams that were created when a smaller galaxy collided with, and its remnants then began to orbit, the Milky Way. Three versions of this photograph were made: a muted version for the background, a regular version for the disc and a super-stretched starless version for the stellar streams and halo. They were then combined into a single image. Photographed at Pie Town, New Mexico, USA, on 5 May 2021. Photo by Utkarsh Mishra/Michael Petrasko/Muir Evenden/APOTY
Winner - Aurorae category
The Northern Lights are one of the most interesting natural phenomena. Although they are usually witnessed in the winter months, this photograph was taken during the late spring. It shows the dancing Aurora Borealis, reflected in a little frozen lake above the Eystrahorn mountain, Hvalnes, Iceland, on 10 April 2021. Photo by Filip Hrebenda/APOTY
Runner-up - Planets, comets and asteroids category
Here, Jupiter can be seen alongside three of the planet’s largest moons. The famous Great Red Spot is clearly visible on Jupiter itself, along with many other spots and storms. Similar details are also evident on all three of the Jovian moons. The bright ray crater Osiris can be seen on the moon Ganymede at the upper left.

Runner-up - Stars and nebulae
The Flaming Star Nebula (IC 405, SH 2-229 or Caldwell 31) is an emission and reflection nebula in the constellation Auriga. It lies about 1,500 light years from Earth and is about 5 light years across. Photographed in Fareham, Hampshire, UK, on 22 February 2022. Photo byMartin Cohen/APOTY
Runner-up - Galaxies category
NGC 5426 and NGC 5427 are two spiral galaxies of similar size engaged in a major interaction. Known collectively as Arp 271, the interaction is expected to continue for tens of millions of years. Photographed at El Sauce Observatory, Hurtado, Coquimbo Region, Chile, between 3 June 2021 and 1 January 2022. Photo by Mark Hanson/Mike Selby/APOTY
Runner-up - People and space category
Built between 1974 and 1981, this spaceship-like structure was designed by Georgi Stoilov and involved the removal of more than 15,000 cubic metres of rock from the peak of Buzludzha, reducing the mountain’s height by 9 metres. Although the building is now closed to the public, its space-age silhouette is the perfect complement for dramatic images of the night sky. Photographed at Buzludzha, Balkan Mountains, Stara Zagora Province, Bulgaria, on 12 August 2021. Photo by Mihail Minkov/APOTY
Runner-up - Our Sun category
The Sun looks different every time astrophotographers capture an image as new sunspots form, grow and eventually fade away. The photographer selectively filtered out all wavelengths of light except a narrow red band (known as the H-alphaline) to reveal an active region of change of the Sun in this detailed image.

Runner-up - Skyscapes category
Some of the most exquisite locations in Death Valley National Park are the salt flats at Badwater Basin. Located 86 metres below sea level, the basin is the lowest point in North America. Every winter brings new rainwater to the flats and the continuous freeze-thaw-evaporate process creates these hexagonal patterns in the mud.

Runner-up - Our Moon category
This is a mosaic of the crescent Moon, made up of 32 separate images. In this image you can see the most famous craters, rims, mountains, domes and seas of this lunar phase. Photographed at Porto Mantovano, Lombardy, Italy, on 19 January 2021. Photo by Andrea Vanoni/APOTY
Runner-up - Aurorae category
This photo, captured over Cameron River in Canada’s Northwest Territories, shows the differentiation between the aurora and the dark sky. Photographed near Yellowknife, Northwest Territories, Canada, on 1 September 2021. Photo by Fred Bailey/APOTY
