From Earth vs From Space
The observations made by the Rosetta orbiter and Philae lander are reshaping researchers’ ideas about comets. The year of research includes the comet’s unusual surface terrace structure, its formation
from two colliding objects producing the unusual rubber duck shape, and the
surprising detection of molecular oxygen – familiar on Earth but not on
a comet. you can see more about it here
Above, you can see the difference of vantage points: a telescopic image of Comet 67P captured from Earth versus the view from Rosetta’s NAVCAM 127 km (79 miles) from the comet, both taken recently.
