In pictures: Astronomy Photographer of the Year 2017

From the northern lights to noctilucent clouds, the range of subjects, in this year’s competition covers all things astronomical. Here is a selection of finalists images.A battle that you’re losing

Haitong Yu

The Milky Way, which is on a small radio telescope at the Miyun Station of the National Astronomical Observatory of China, Beijing, Haitong Yu photography.

“The image depicts the luminous pollution, together with an electromagnetic noise, he has shot several optical and radio observatories near cities both blind and deaf,” says the photographer.

To make this image, Haitong Yu used a light-pollution filter and stacked more frames to show the Milky Way over the city of light. Auroral Corona

Yulia Zhulikova

This photo of the aurora borealis swirling above the trees covered with snow in Murmansk, Russia, was made by Yulia Zhulikova. The trees glow a vivid pink, which is highlighted by street lamps.
Crescent of the Moon above the Needles

Ainsley Bennett

Ainsley Bennett captures the waxing crescent Moon setting in the evening sky above the Needles Lighthouse on the western tip of the Isle of Wight.

Despite the Moon being a thin crescent, the rest of the figure is defined by the light of the sun reflected back from the surface of the Earth.The eastern emphasis

Paul Andrew

A great devastation hedge relief extending from the surface of the Sun, Paul Andrew image.

A number of different highlight types have been observed coming from the Sun, and the hedge prominence is so called because of the grouping of small bumps similar rough and wild shrubs. The fall of milk

Prisca Law

Taken from the Victoria Peak, the highest mountain of the Island of Hong Kong, Prisca Reads the image shows a very busy city, in contrast with the peaceful starry sky.

The yellow haze above the landscape is the light pollution. Along the coast roads, the pattern of the light means to the hectic life of the city.Turn on the lights

Nicolas Alexander Otto

After a long walk from his small cabin to Kvalvika, Lofoten Islands, Norway, Nicolas Alexander Otto arrived on the slopes above the beach at about midnight.

During the trip, the aurora borealis display was relatively weak. But when he made it to the beach, the sky lights up in a colourful spectacle of green and purple, framed by the mossy landscape.

The image was composed of six different exposures due to the high ISO of the camera setting and the thermal noise in the foreground. The sky was added from a of these exposures. Shooting stars and Jupiter

Rob Bowes

A shooting star crosses the sky above the craggy landscape of Portland, Dorset, as the planet Jupiter lights up Rob Bowes photography.

The image was made from two exposures: one for sky and one for the rocks. Light transit

Dani Caxete

The International Space Station moves across the face of the Earth’s natural satellite, the Moon, photographed in the middle of the day by Dani Caxete.

The ISS is lit by the Sun, to a height of nine degrees on the horizon.

Like the Moon, the ISS receives the rays of the sun during the different orbits of Earth a day, making it possible to see when the Sun is still high.

This image was made with only one shot, no composite or clipping in the process.The road back home

Ruslan Merzlyak

Noctilucent clouds stretch across the Swedish sky, illuminating Ruslan Merzlyakov home race at this dramatic display.

Noctilucent clouds are the highest clouds in the earth’s atmosphere, and the above form to 61 (200,000 ft).

Thought to be formed by ice crystals, clouds occasionally become visible at dusk, when the Sun is below the horizon and illuminates them.Near Earth Object

Derek Robson

31 October 2016, Near Earth Asteroid 164121 (2003 YT1) has had a close encounter with the Earth at three million miles away.

This asteroid, Apollo, with an orbital period of 427 days, it was discovered by the Catalina Sky Survey on December 18, 2003.

Derek Robson attempt imaging of the asteroid was made with a camera on a fixed tripod, that is controlled by Astrophotography software Tool. Nebula Medusa

Chris Heapy

Lying in the constellation of Gemini, IC443 is a galactic supernova remnant, a star that could explode up to 30,000 years ago,

His appearance is globular and has earned the celestial structure, the moniker of the Jellyfish Nebula.

In this photo taken by Chris Heapy, in the top left of the Jellyfish Nebula is a much fainter background area of nebulosity, which is a large cloud of mostly molecular hydrogen gas and dust.

Professional, the observatory, the data demonstrate that what we are seeing are the two lobes are superimposed on one another, but from this point of view appears as the head of medusa (left) and the other lobe (to the right) as the tentacles.
