Gemini Planet Imager snaps first direct image of exoplanet Beta Pictoris b (slide show)

Although its not the sharpest you've ever seen, the photograph above is a direct image of a planet (Beta Pictoris b) which is orbiting a star 63 million light years away. In addition to the distance, there is the problem of overcoming the dazzling light of the star. Think of pointing your camera directly into a searchlight & trying to take a photograph of a moth flying just to the side.
Gemini Planet Imager has done something similar, except that the star is very much brighter, & both star & planet, very much further away.
