“Roseta-NBv5” (Rosette Nebula) by Juan Ignacio Jiminez

Astronomy Photographer of the Year 2015

13 September 2015 Astronomy Now

Measuring 50 light-years in diameter, the large, round Rosette Nebula is found on the edge of a molecular cloud in the constellation of Monoceros the Unicorn. At the core of the nebula the very hot young stars have heated the surrounding gaseous shell to a temperature in the order of 6 million kelvins resulting in the emission of copious amounts of X-Rays. Here the photographer has applied a false colour palette to several pictures using narrowband filters, which only allow a specific colour of light to reach the camera, with each one linked to an interstellar gas, resulting in the striking blues and oranges.

The Insight Astronomy Photographer of the Year competition is an annual celebration of the most beautiful and spectacular visions of the cosmos by astrophotographers worldwide. In 2015 the competition launched for its seventh year, with new categories and more prizes up for grabs.
