'''The "E" or "Barnard's E" Nebula''' (officially designated as [[Barnard Catalogue|Barnard]] 142 and 143) is a pair of [[Dark nebula|dark nebulae]] in the [[Aquila (constellation)|Aquila]] constellation.  It is a well-defined dark area on a background of [[Milky Way]] consisting of countless stars of all magnitudes, getting its name from its resemblance to the letter [[E]] in the [[Latin alphabet]].<ref>{{cite news|last=Armstrong|first=Mark|date=21 August 2023|title=Capitalise on Barnard’s giant ‘E’ in the sky|url=https://astronomynow.com/2023/08/21/capitalise-on-barnards-giant-e-in-the-sky/|work=Astronomy Now|access-date=10 October 2023}}</ref>  Its size is about that of the [[full moon]], or roughly 0.5 degrees, and its distance from earth is estimated at 2,000 [[light years]].
