The "E" or "Barnard's E" Nebula (officially designated as Barnard 142 and 143) is a pair of dark nebulae in the 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 . [ 1 ]

The Big E is America’s Premier Exposition and world’s only multi-state fair, representing all six New England States, with entertainment, unique foods, competitive livestock shows, shopping, a circus and much more.

The Big E, formally known as The Eastern States Exposition, is an annual fair in West Springfield, Massachusetts, which opens on the second Friday after Labor Day and runs for seventeen days. It is billed as " New England 's Great State Fair," the largest agricultural event on the eastern seaboard and the fifth-largest fair in the nation. [2] .

The Big E is the largest event on the East Coast and the fourth largest fair in North America. Attendees can enjoy hours of free entertainment and attractions, terrific food, plus the best that New England—and beyond—has to offer.

B142 and B143 are two of these nebula, and how appropriate it is that the two nebulae appear to form a large "E" in the sky - just like astronomer Barnard's first two initials! The E formed by B142 and B143 is about 1 degree tall - equivalent to the diameter of 2 Full Moons. The nebulae are made of dust approximately 2,000 light years from us.

2025年3月18日 · This image shows six different, unrelated planetary nebulae, all with similar, bipolar morphologies. These six objects, NGC 6302, NGC 6881, NGC 5189, M2-9, Hen 3-1475, and Hubble 5, are all ...

The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the …

2023年8月21日 · Barnard’s ‘E’ in Aquila is formed from the dark nebulae Barnard 142 and 143 (B142/143). At their most dramatic, dark nebulae, dark clouds of interstellar gas (largely molecular hydrogen) and dust that can block out or obscure the light from stars and other objects lying beyond it, are spectacular deep-sky objects.

The astronomer E. E. Barnard cataloged dark nebulae throughout the sky. They are areas of gas and dust that block the light of the stars behind them, so they appear as relatively empty patches of sky.
