Neptune and Uranus have much in common — they have similar masses, sizes, and atmospheric compositions — yet their appearances are notably different. At visible wavelengths Neptune has a distinctly bluer color whereas Uranus is a pale shade of cyan. In this podcast, Dr. Patrick Irwin discusses new research shedding light on the differences in the colors of Uranus and Neptune.
