Only that central part is visible through a telescope (identified by Messier as #16 in his catalog) and it does indeed look like an eagle visually. Calling the larger structure the Eagle Nebula is quite recent. The Eagle Nebula was named because of the visual appearance (through an eyepiece) of the section also called "The Pillars of Creation" long ago, before any of that other larger structure was even known. You might not realise it if you look solely at Hubble's Pillars of Creation image in isolation, but they really only make up a small portion of the Eagle Nebula region. The pillars are regions of dark dust and gas contained within the Eagle Nebula that stretch about 5 lightyears long and hide embedded newborn stars from view. Despite their notoriety, the pillars represent only a small part of the Eagle Nebula, measuring 4 to 5 light-years across, according to NASA. Originally taken in 1995(opens in new tab) by the Hubble Space Telescope, the Pillars of Creation is one of the most iconic astronomical images of all time. If however I am wrong, please tell me how. the name became popular when HST captured that region. according to and, the pillars of creation are within the Eagle Nebula, and I don't think the astronomers that named this nebula Eagle had equipment strong enough to distinguish the pillars of creation. The Eagle emission nebula, tagged M16, lies about 6500 light years away, spans about 20 light-years, and is visible with [url= " >binoculars toward the > Already visible are several young bright blue stars whose light and winds are burning away and pushing back the remaining filaments and walls of gas and dust. In this cavity, tall pillars and round globules of dark dust and cold molecular gas remain where stars are still forming. Through this window, a brightly-lit workshop appears where a whole open cluster of stars is being formed. A closer look at the Eagle Nebula, however, shows the bright region is actually a window into the center of a larger dark shell of dust. Explanation: From afar, the whole thing looks like an eagle.
