SAGITTARIUS ARM ABOVE OLD TOWN OF CORFU Taken by Bill Metallinos on February 6, 2016 @ Corfu, Greece

Sagittarius Arm above Old Town of Corfu

What does a Spiral arms looks like above two towns?
Our Galaxy Milkyway, a cosmic island with almost 200 billion stars forming Spiral arms, one of this arms can be seen in the above capture.

With the Sagittarius Star Cloud at the centre and top of the the photo, while just above the light-polluted old town of Corfu we can see the Lagoon Nebula, Messier 8 a giant interstellar cloud in the constellation Sagittarius estimated to be between 4,000-6,000 light years from the Earth and actual dimension of 110 by 50 light years. While next and above M8 it is the Triffid Nebula, also known as Messier 20, is an H II region located in Sagittarius. It was discovered by Charles Messier on June 5, 1764. It is approximately 5000 ly away from Earth. Its apparent magnitude is 6.3.
Also next to Sagittarius Star Cloud is the M17 an H II region in the constellation Sagittarius, Omega Nebula is between 5,000 and 6,000 light-years from Earth and it spans some 15 light-years in diameter.

Unfortunately we can barely see the Milkyway Galaxy, the two towns Corfu and Igoumenitsa are making light-pollution to the night-sky. As we can see the lights from the new port are so bright, even there are anti-lightpolution and spot all the light down. Bust still, the light of the monuments like old Fortress or the city lights are light-up the nightsky.

Enjoyable presence on this capture is the Waning Crescent Moon age 27 days old on the left side of the picture, with disc illumination just 7% and just 378771 km away from us...
