Collage of galaxies in the Herschel Reference Survey at infrared/submillimeter wavelengths by Herschel, left, and at visible wavelengths from the Sloan Digital Sky Survey, right. The Herschel image is colored with blue representing cold dust and red representing warm dust; the SDSS image shows young stars in blue and old stars in red. Together, the observations plot young, dust-rich spiral/irregular galaxies in the top left, with giant dust-poor elliptical galaxies in the bottom right.

The tiny temperature fluctuations of the cosmic microwave background, shown here as color, trace primordial density fluctuations in the early universe that seed the later growth of galaxies. Gravitational waves from inflation are expected to produce much a fainter pattern that includes twisting B-mode polarization, consistent with the B-mode polarization pattern observed by BICEP2, which is shown here as black lines. The line segments show the polarization strength and orientation at different spots on the sky. Image credit: BICEP2 Collaboration.
