Comment:
 Barnard's "E" are a pair of dark nebulae near the star Tarazed (Gamma Aquilae). They are some 2 kly distant. Dark nebulae are vast clouds of interstellar matter. B142 and B143 are more than 60 ly across. We can see them because they block the visible light of stars behind them. In time such clouds may develop denser areas that will finally collapse into new stars.
