       Discover the cosmos! Each day a different image or photograph of our   
         fascinating universe is featured, along with a brief explanation   
                       written by a professional astronomer.

                      Supernumerary Rainbows over New Jersey

      Explanation: Yes, but can your rainbow do this? After the remnants of   
      Hurricane Florence passed over the Jersey Shore, New Jersey, USA in   
      2018, the Sun came out in one direction but something quite unusual   
      appeared in the opposite direction: a hall of rainbows. Over the course   
      of a next half hour, to the delight of the photographer and his   
      daughter, vibrant supernumerary rainbows faded in and out, with at   
      least five captured in this featured single shot. Supernumerary   
      rainbows only form when falling water droplets are all nearly the same   
      size and typically less than a millimeter across. Then, sunlight will   
      not only reflect from inside the raindrops, but interfere, a wave   
      phenomenon similar to ripples on a pond when a stone is thrown in. In   
      fact, supernumerary rainbows can only be explained with waves, and   
      their noted existence in the early 1800s was considered early evidence   
      of light's wave nature.
