The Insight Astronomy Photographer of the Year 2015 contest shares its winners' mind-bending images of distant galaxies, glowing green auroras and faraway planets.
Italian photographer Paolo Porcellana captured a blazing prominence emitted from the sun in this winning image from the Insight Astronomy Photographer of the Year contest. It took top honors in the Our Sun category. Porcellana used a homemade telescope in the process of photographing this spectacular event.

Astronomy photo contest overall winner
French photographer Luc Jamet took the crown with this image of a solar eclipse taken on March 20 in Norway. The moon is a black dot inside the sun's glow and Venus makes an appearance as a pinpoint in the upper left.
This photo won both the Skyscapes category and the overall top award for the Insight Astronomy Photographer of the Year 2015 contest.
"It is one of those heart-stoppingly beautiful shots for which you feel grateful to the photographer for sharing such an exceptional moment," writes judge Melanie Vandenbrouck.

Photographer Matt Robinson from the UK titled this image "Sunderland Noctilucent Cloud Display." Robinson's first ever attempt at astrophotography earned him the runner-up award in the Skyscapes category.
According to NASA, noctilucent clouds "form at the edge of space 83 km above our planet's polar regions in a layer of the atmosphere called the mesosphere. Seeded by 'meteor smoke,' NLCs are made of tiny ice crystals that glow electric blue when sunlight lances through their cloud-tops."

Omega Centauri shines
Photographer Ignacio Diaz Bobillo is fascinated by Omega Centauri, a globular star cluster in the Milky Way.
"I always come back to this spectacular object, especially when it is high up in the sky on a night of good seeing, as in this case," he writes about the image that took the top spot in the Stars & Nebulae category.

Pinhole view of the sun's trails
This image is a unusual entry into the Insight Astronomy Photographer of the Year contest. Photographer Chris Bakley captured it over the course of six months using a homemade pinhole camera. It tracks the movement of the sun across the sky, creating an otherworldly view of the landscape in the process.
The photo was "highly commended" in the Our Sun category.
