This is a transonic NASA Ares I-X test rocket launched on 28 October 2009 from Florida, USA. The white “ring” or “halo” on the rocket is a Prandtl-Glauert Condensation Cloud. It’s due to a phenomenon of fluid mechanics called the Prandtl-Glauert Singularity. Photographer: Scott Andrews [2363 x 3000] via /r/spaceporn http://ift.tt/26L3lFq
