Captivating photographs of our Milky Way, Andromeda galaxy and stunning images of the Aurorae are among the winners of the Insight investment astronomer photographer of the year award.
The winning pictures can be seen in an exhibition at National Maritime Museum in Greenwich, south-east London, from the 23rd of October.
Solar minimum may be seen as a quiet sun and deemed dull in white light, but if you look closely at the small-scale structure, the surface is alive with motion. This surface is about 100km thick and the ever-boiling motion of these convection cells circulate, lasting for about 15-20 minutes. They are about 1,000km in size and create a beautiful ‘crazy paving’ structure. Photograph: 2020 astronomy photographer of the year.
The Tycho crater is one of the most famous on the moon. This huge impact has left impressive scars on the lunar surface. With the colours of the soil, Tycho is even more impressive. This picture combines one session with a black-and-white camera, to capture the details and sharpness, and one session with a colour camera, to show the colours of the soils. These hues come mainly from metallic oxides in small balls of glass. The blue shows high titanium oxide concentration and the red shows high iron oxide concentration.

During the 2019 partial lunar eclipse, the photographer managed to capture this fantastic image of the moon while a small cloud passed in front of it. You can see the Earth’s shadow on the top right and its striking orange colour caused by the sun’s light passing through the atmosphere. This is a high dynamic range image, meaning the darker, shadowed region is correctly exposed as well as the much brighter parts of the moon.

Have you ever dreamed of touching a galaxy? This version of the Andromeda galaxy seems to be at arm’s length among clouds of stars. Unfortunately, this is just an illusion, as the galaxy is still 2m light years away. To obtain the tilt-shift effect, the photographer 3D printed a part to hold the camera at an angle at the focus of the telescope. The blur created by the defocus at the edges of the sensor gives this illusion of closeness to Andromeda.

NGC 3628 is a popular galaxy target for both astrophotographers and visual observers, with its distinctive dust lane. Studies by professional astronomers have shown that the evolution of some galaxies are the product of a series of minor merges with smaller dwarf galaxies. This image is an epic undertaking of five years of exposures taken with three telescopes, although the majority of the exposure was in 2019. The goal of this mosaic is to show the tidal tail, measuring 300,000 light years in length.

Despite what the title might imply, this image has nothing to do with space warfare. It shows four lasers of one of the telescopes at Paranal observatory pointing towards a globular cluster in the large magellanic cloud. The lasers excite sodium atoms located in a layer about 80–90km above the ground. This creates the four artificial ‘stars’ at the very ends of the laser beams.

The star in the centre of the image is the Albireo double star, surrounded by the trails of moving satellites. How many more might there be by the time we reach next year’s competition? There could be thousands of moving dots in the sky. In order to create astrophotos, photographers have to carefully plan where to place the telescope, and this will be more difficult in the future with more satellites in the way.

This image depicts the photographer climbing the radio telescope and Mingantu solar radio telescope array. First the photographer tested and moved his camera so that the M8 and M20 nebulae would appear right next to the telescope. After taking the foreground image, he moved his camera a little bit but still pointing at the same location in the sky, and captured the background with an equatorial mount.

At the top of fjords in Arctic Norway, the photographer was met with an unknown sky. Was it aliens? Was it the supernatural? He captured a series of photos to record the night and didn’t know until the next day that the colours were actually created by the auroral zone upwelling rocket experiment from Andøya Space Centre, which dispersed gas tracers to probe winds in Earth’s upper atmosphere.

This image shows the close alignment of the moon and Jupiter that happened on 31 October 2019. In the full resolution picture, three of Jupiter’s moons also visible. This small project is a big challenge that involves a lot of luck and good conditions. To capture this phenomenon in such a big scale was quite demanding in data acquisition as Jupiter and the moon travelled across the sky quite fast. It happened in altitude only 9 degrees above the horizon.

On 3 December 2019, the cloud cleared around mid-evening to reveal steady skies over the photographer’s home. He turned his telescope to Uranus and started gathering video frames using an infrared filter to bring out cloud details on this otherwise visually bland planet. For an object as faint as Uranus, this means individual frames are noisy. That night the lighter polar region could be easily seen – an exceptional situation and a testament to the unusually steady skies.

The photographer was searching for clear skies in Finnish Lapland to capture the beauty of a polar night and could not believe his eyes when he saw what was waiting behind the clouds. Polar stratospheric clouds are something Kast had been searching for many years and had seen only in photographs until that day. He took his camera on to a frozen river to get a good view and started to take photos. The clouds slowly changed their shape and colours to create a painterly image.

The photographer took this image during a trip through Jordan. He stayed for three days in the desert at Wadi Rum. The photographer tried to capture the amazing starry sky over the desert. He used a star tracker device to capture the image. Leibermann found this red dune as a foreground and snapped the imposing Milky Way centre in the sky.

NGC 3576 is a well-known nebula in southern skies, but is shown here without any stars. Software reveals just the nebula, which has been mapped into a false colour palette. The scene takes on the look of a celestial fire-maelstrom. The image is intended to reflect media images taken in Australia in 2019 and 2020, where massive bushfires caused the destruction of native forests and have claimed more than 12m acres of land. It shows nature can act on vast scales and serves as a stark warning that our planet needs nurturing.

This target is officially known as Sh2-308 but the photographer has always enjoyed calling it the Dolphin nebula. It is a bubble of gas being shed by the bright blue star in the centre of the image as it enters its pre-supernova phase. The red star, to the right, could possibly be influencing the shape too and might be responsible for the bill of the dolphin. While it will not explode in our lifetimes, seeing the warning signs is valuable.

The photographer imaged IC 1396, known as the Elephant’s Trunk, in the Hubble palette from my light-polluted backyard in Coppell, Texas. This image presents the Elephant’s Trunk surrounded by the emission clouds with a misty feeling and an emphasised blue doubly-ionised oxygen area as the background. It gives the feeling of the trunk emerging from the distance.

Dark River is a sculptural work that maps, or mirrors, the Milky Way using one of the largest images ever made of its central areas. This gigapixel image of the Milky Way, showing about 84m stars, is reworked into a sculptural ‘affective space’ that affords a bodily and imaginative engagement with the viewer. The image was obtained with the Vista survey telescope at ESO’s Paranal observatory in Chile and contains nearly 9bn pixels.

Photographing a planetary alignment requires rigour and patience but also a lot of luck. That evening, despite preparing everything for a week, the photographer encountered clouds. The magic started after sunset, where the moonset, Venus, Mercury, the star Antares, Jupiter and Saturn could be seen over the Indian Ocean. By looking at the sky map. Note also the presence of Alpha Centauri on the left of the image as well as our immense galaxy, the Milky Way.

This is the sun, captured from London in September 2019. This is a composite of two images: one exposed for the solar prominences and the other for the solar disc. The solar disc image was inverted, converted to false colour and blended with the prominence in Photoshop as a dark layer. This was the first time the photographer used this technique.
