NASA has released an image capturing the first look at Pluto's blue atmosphere in infrared wavelengths which was taken by its New Horizons
spacecraft. 

The photo captured in July last year was made with data from the New Horizons Ralph/Linear Etalon Imaging Spectral Array instrument.
In the image, sunlight is coming from above and behind Pluto while New Horizons was about 180,000 kilometres away. 

The image covers LEISA's full spectral range (1.25 to 2.5 microns), which is divided into thirds, with the shortest third being put into the blue channel, middle third into the green channel, and longest into the red channel.
