My scientist brain immediately notices that the Moon looks small compared to Earth because of how close Rosetta passed to us—just under 2000 kilometers (1200 miles) above Earth’s surface, a fantastically close shave—as well as how dark the Moon looks. Its surface is, on average, far less reflective than Earth’s, so to expose the planet correctly means the Moon looks much fainter.
But the part of my brain that appreciates art and beauty just sees the panoply of clouds, the graceful arc of the world, the thinner arc of atmosphere (visible on the left) allowing us to breathe, and the ghostly, milky looming of the Moon.
This is science, this is engineering, and this is art.
Some of the artistry came long after. My friend Emily Lakdawalla, writer for The Planetary Society Blog, took the raw image from Rosetta and reprocessed it to clean it up, enhancing the natural beauty stored in those zeros and ones. The raw image is inset here to give you an idea of what she did; click both to see them far larger.
