Astronomy Photographer of the Year 2017

This picture of the aurora borealis swirling above snow covered trees in Murmansk, Russia, was made by Yulia Zhulikova. The trees glow a vivid pink, highlighted by street lamps.

Ainsley Bennett captures the waxing crescent Moon setting in the evening sky over the Needles Lighthouse on the western tip of the Isle of Wight.
Despite the Moon being a thin crescent, the rest of its shape is defined by sunlight reflecting back from the Earth's surface.

Taken from Victoria Peak, the highest mountain on Hong Kong Island, Prisca Law's image shows a busy city in contrast to the peaceful starry sky.
The yellow haze above the landscape is light pollution. Along the coastline roads, the pattern of light signifies the fast-paced life of cities.

After a long hike from his small cabin to Kvalvika, Lofoten Islands, in Norway, Nicolas Alexander Otto arrived at the slopes above the beach at about midnight.
During the hike, the aurora borealis display was relatively weak. But when he made it to the beach, the sky ignited in a colourful show of greens and purples framed by the mossy landscape.
The image was composed from six different exposures due to the high ISO camera setting and thermal noise in the foreground. The sky was added from one of these exposures.
