Nasa has unveiled stunning mosaics of Pluto and its largest moon Charon made up of thousands of faces from the general public.

The mosaic represent the global response to its '#PlutoTime' social media campaign.

This was developed by Nasa so that people could experience the sunlight level on Pluto at noon - generally around dawn or dusk on Earth.

They asked people to submit images during Pluto time, which have now been assembled into detailed mosaics of Pluto, Charon, and a combined image of the two.

Since the Pluto Time campaign was announced in June, the space agency has received more than 7,000 image entries from around the world.

The mosaics include not only dim skies on Earth, but famous landmarks, selfies, and even family pets.

According to Nasa, the files are so large that, at current resolution, they would make an 11 x 11' print.

The Pluto Time idea stemmed from a frequently-asked question of New Horizons scientists: how are you going to take pictures of Pluto, given that it's so far from the sun?

WHAT IS PLUTO TIME? Even at Pluto's distance from the sun, it isn't completely dark all the time. In fact, for a brief a moment near dawn and dusk, the illumination here on Earth matches that of noontime on Pluto. Nasa calls this moment Pluto Time, and its interactive tool lets you exactly when your region's next Pluto Time is taking place. Advertisement

Even at Pluto's distance from the sun, it isn't completely dark all the time.

In fact, for a brief a moment near dawn and dusk, the illumination here on Earth matches that of noontime on Pluto.

Nasa calls this moment Pluto Time, and its interactive tool lets you exactly when your region's next Pluto Time is taking place.

'We realised that we could make a web tool that would estimate approximately when the light levels dropped to Pluto levels,' said Alex Parker, research scientist at the Southwest Research Institute.

'We looked up tables of illumination levels during various stages of twilight - used to determine when streetlights come on and such - and determined how low the sun would need to be on a clear day to match Pluto. After that is was a matter of doing the math.'

Nasa's Solar System Exploration Public Engagement team assembled the mosaics, using around 1,500 to 2,100 images for each.

Some of the images are occasionally repeated by the software to correctly fill in the colours and provide the proper shape of Pluto and its terrain.

'It's gratifying to see the global response to Pluto Time, which allowed us to imagine what it's like on Pluto, some three billion miles away,' said Jim Green, Nasa's director of planetary science.

'This is a wonderful example of how space exploration and science unite us with a common bond.'
