Gazing on the cosmic plughole

I wonder if Brandon Yoshizawa knew that the exhaust plume of a Falcon 9 rocket would take on the shape of a flower as its hot discharge made contact with colder air of the upper atmosphere? He was certainly in the right place at the right time and with the requisite skill to capture an extraordinary image. The result, Flower Power, is a perfect example of the blend of art and science that makes the annual Astronomy Photographer of the Year exhibition at the Greenwich National Maritime Museum so special.
