Pickering's Triangle is much fainter and has no NGC number (though 6979 is occasionally used to refer to it). It was discovered photographically in 1904 by Williamina Fleming (after the New General Catalogue was published), but credit went to Edward Charles Pickering, the director of her observatory, as was the custom of the day.
The visual portion of the Cygnus Loop is known as the Veil Nebula, also called the Cirrus Nebula or the Filamentary Nebula. Several components have separate names and identifiers, [2] [3] including the "Western Veil" or "Witch's Broom", the "Eastern Veil", and Pickering's Triangle.

An example of light exhibiting sub-Poissonian statistics is squeezed light. Recently researchers have shown that sub-Poissonian light can be induced in a quantum dot exhibiting resonance fluorescence. [5] A technique used to measure the sub-Poissonian structure of light is a homodyne intensity correlation scheme. [6]
Edward Charles Pickering (July 19, 1846 – February 3, 1919) was an American astronomer and physicist [1] and the older brother of William Henry Pickering. Along with Carl Vogel , Pickering discovered the first spectroscopic binary stars.
The Pickering scale is a scale of rating astronomical seeing, the blurring of images caused by atmospheric turbulence. [1] [2] The scale was developed by William H. Pickering (1858–1938) of Harvard College Observatory, using a 5" (13 cm) refractor. [3] [4] Seeing of 1 to 3 is considered very poor, 4 to 5 is poor, 6 to 7 is good, and 8 to 10 ...
Viktor Coble listed Xanthar's Guide To Everything as #8 on CBR's 2021 "D&D: 10 Best Supplemental Handbooks" list, stating that "unlike a lot of the other books in 5e, it is a lot more versatile. Not only does it have the feeling of a campaign plot hook, but it also offers a lot of new subclasses, spells, and tools for new ways to play and ...
Wyatt also writes the text for the series of Art of Magic: The Gathering coffee table books, which reprint illustrations from the cards with details for each plane's lore; the Plane Shift releases were created to allow players to use those books as campaign setting guides by providing the necessary rule adaptations.
