Master of Ragusa immortalizes the “Green flash”, the photo selected by NASA.

The astronomical photo of the day chosen by NASA is by the teacher from Ragusa Marcella Giulia Pace. (Https://apod.nasa.gov/apod/astropix.html). The photo frames and returns the “Green Flash (green ray)”, caused by a refraction of sunlight through the atmosphere.

“It is very difficult to catch a solar green ray – explained Pace to AGI – also celebrated by Giulio Verne, and even rarer is it to catch the lunar one. It is even more difficult to be able to photograph those of Venus and Mercury: the Iblei coast, south-east of Sicily, offers some of the best azimuth exposures for shooting at sunset, and these phenomena can be observed with less rarity than elsewhere ».

NASA understood the difficulties in finding the right moment, and rewarded the photos, taken in Sicily in Marina di Ragusa on March 18 (Sun), in Modica on May 8 (Moon) and May 24, 2020, on the occasion of the conjunction of Venus and Mercury. Elementary school teacher and astrophotography, Pace is a UAI (Italian Astrophiles Union) member, and member of the “Pictores Caeli” group, a group of astrophotographers already known at the Apos.

The US Space Agency’s “Astronomy Picture of the Day” provides a different image of our Universe every day accompanied by a brief explanation edited by astronomers Robert Nemiroff and Jerry Bonnell.

“It is the third recognition that I receive from NASA – Pace adds – I am always happy to offer NASA my images of atmospheric and astronomical optical phenomena, because NASA’s vocation is not only scientific in the strict sense, but also educational and popular. harmony with the other aspect of my professional life at school: I love trying to convey my love for observing what appears obvious in nature, and therefore unnoticed. My photos are shots of what is there for all to see, if only we stopped to observe the world around us, without too many distractions ».
