English: Scientists believe our Universe started with a rapid expansion, during which tiny quantum seeds were imprinted into the fabric of spacetime, leading in time to creation of galaxies, stars and planets, including the Earth. To prove this theory scientists are searching for B-modes, a spiral type of polarization imprinted in the microwave sky. However, Milky Way emits dust, which is also polarized, and scientists must learn how to distinguish the two signals. This image was created by taking dust emission as measured from the Planck satellite and converting its intensity into a polarization pattern. The bright yellow band is Milky Way as seen in the microwave sky. A B-mode was imprinted into a single spot by locally rotating the dust polarization pattern by 45 degrees. A hilly landscape was added at the bottom to represent that many of the B-mode experiments are ground based, in places from Antarctica to Atacama desert in Chile.
