Description - Nasa and European Space Agency has been observing this Comet since 20 years. ESA sent Rosetta Space Craft to this comet. Recently Rosetta landed on comet's surface and sent many images of this.
In this image, i observed a kind of old structure or historical fort with full of wall around it. This structure seems damage for sometime but its beauty clearly appears here.
It is believed that some radio signals came to Earth from this comet 20 years back. So that Nasa and ESA try to solve that mystery..!!
