The interesting part about this photo isn't necessarily the picture itself, rather the information that was gathered from it. As Comet 67p arrives closer to the sun and expels its gas and dust, scientists were able to discover some important facts about the early universe, including the fact that our Earth's water could not have come from comet collisions due to 67p's water being of significantly different composition. Also interesting is that the comet appears to have no magnetism, thus suggesting that magnetism was not of any key importance in the development of the early universe. Again, the fact that scientists learned this much from just one passing by comet is quite incredible.
