Every day our eyes catch the light of our memories – time spent with family, the journey to work, a special holiday, a beautiful sunset or a dark starlit night. Each image captured is a picture drawn in light – a photograph: only to be lost in our minds or forever forgotten. Nearly two hundred years ago a small group of amateur scientists achieved what had eluded mankind for centuries – the ability to capture a permanent record of an image seen by their own eyes – a moment in time frozen onto a surface. They had discovered Photography. They were the ‘Catchers of the Light’.

Pickering's Triangle NGC 6979

Pickering's Triangle is part of the Cygnus Loop supernova remnant, which includes the famous Veil Nebula.
Astronomers estimate that the supernova explosion that produced the nebula occurred between 5,000 to 10,000 years ago.
Pickering’s Triangle was discovered in 1904 by Williamina Fleming of the Harvard Observatory while examining photographic plates of the area. The object was named in honor of her boss, astronomer Edward Charles Pickering, then director of the Observatory. Pickering’s Triangle goes by a number of aliases, including Pickering’s Wedge, Fleming’s Triangular Wisp, and Simeis 3-188. Current estimates place this supernova remnant at about 1800 light years from Earth.
The entire Veil Nebula complex, of which Pickering’s Triangle is but a portion has an apparent diameter of about 3° or nine full moons!
