This year’s Insight Astronomy Photographer of the Year competition received a record 2700 entries by astrophotographers from 59 countries around the world. These astonishing pictures reveal fresh perspectives on astrophotography favourites alongside some of the great astronomical events of the last year.
In subsequent weeks we will showcase the winning images from all 11 categories, but if you wish to see them all together, the Royal Observatory Greenwich has an exhibition open 18 September 2015 — 26 June 2016. Hours: 10.00–17.00, entry is free.
The instantly recognisable five-star M-shaped pattern of stars representing the constellation Cassiopeia (pronounced kas-ee-uh-pee-uh) lies almost overhead in the early evening as seen from the British Isles over the festive period. Cassiopeia is rich in wonderful double and multiple stars, so here’s our guide to some of the best for typical backyard telescopes.
In this image from ESO’s Very Large Telescope (VLT), light from blazing blue stars energises the gas left over from the stars’ recent formation. The result is a strikingly colourful emission nebula, called LHA 120-N55, in which the stars are adorned with a mantle of glowing gas. LHA 120-N55 lies within the Large Magellanic Cloud, a satellite galaxy of the Milky Way.
Comet Lovejoy has been a easy to follow object since the beginning of the year. Throughout May the comet continues its trek towards the north celestial pole, culminating in a close conjunction with Polaris at the end of the month.
