Solar System Portrait - Earth as 'Pale Blue Dot' T-Shirt

This narrow-angle colour image of the Earth, dubbed 'Pale Blue Dot', is a part of the first ever 'portrait' of the solar system taken by Voyager 1. The spacecraft acquired a total of 60 frames for a mosaic of the solar system from a distance of more than 4 billion miles from Earth and about 32 degrees above the ecliptic. From Voyager's great distance Earth is a mere point of light, less than the size of a picture element even in the narrow-angle camera. Earth was a crescent only 0.12 pixel in size. Coincidentally, Earth lies right in the centre of one of the scattered light rays resulting from taking the image so close to the sun. This blown-up image of the Earth was taken through three colour filters -- violet, blue and green -- and recombined to produce the colour image. The background features in the image are artefacts resulting from the magnification.
