Why doesn't the Horsehead Nebula glow like other nebulae?
Horsehead Nebula doesn't glow like other nebulae because it is older than other nebulae and was probably a lot smaller. In addition, Horsehead Nebula is farther away from the Earth than other nebulae, so it may seem that it doesn't glow as bright as other nebulae. No, this isn't right! The horsehead nebula doesn't glow for one reason - it isn't illuminated by any stars whose energy is enough to make the gas shine. That's the only difference between a 'bright' diffuse nebula (like M42) and a 'dark' one like the Horsehead or the Coalsack. M42 (the Orion nebula) is bright because there are several hot, energetic stars embedded inside it, and which cause it to 'shine'.

Is a nebula further from earth than a galaxy?
Earth is IN a galaxy - as is the nebula.
How far is trifid nebula from the Earth?
The Trifid Nebula is about 5,200 light years away from Earth.
Is the sun closer or farther to the earth than the Orion nebula?
Orion Nebula is much further from the earth than the Sun is.
Can the crab nebula produce energy for use on earth?
The Crab Nebula is too far away for its energy to have any impact on Earth.

Who found the Horsehead Nebula?
The Horsehead Nebula was discovered by Mrs. Williamina Fleming on Harvard College Observatory Bache Telescope plate B2312, noted by Professor E. C. Pickering in his Harvard Annals publication of new objects discovered by photography at Harvard in Cambridge, Massachusetts, published in 1890. The discovery was made by her on June 27, 1888, and the plate was exposed on February 6, 1888. It was Mrs. Fleming's job to examine and analyze the photographs for details and possible new objects. Professor Pickering also reported that his brother, William, had immediately speculated that the nebula consisted of dark, obscuring matter: and thus from the very beginning, the correct scientific nature of the phenomenon was comprehended. However, though the large bright nebula IC-434, upon which the Horsehead is superimposed on Earth's line of sight, was catalogued in 1895 (with a mistaken attribution to "Pickering", not Fleming), the Horsehead itself was not generally acknowledged in astronomical catalogues for some years, until Edward E. Barnard included it as his item no. 33 in a paper containing a list of 182 dark 'markings', published in 1919. Though others photographed the Horsehead after 1891, Barnard was apparently the first person to observe and study it visually, in 1913. Stephen Waldee, a California amateur astronomer and researcher, turned up the forgotten and unacknowledged facts in the old Harvard publication and -- with the cooperation of Martha Hazen, Curator of Harvard's Historical Photographs -- the original plate, during a research project in 1989/90. The saga of Mrs. Fleming's work on the nebula and other such objects discovered in Harvard's early photographic program was chronicled and published over the next few years, in a joint Waldee-Hazen paper, a magazine article, and eventually a large research website. Mrs. Fleming's work was finally professionally recognized (unfortunately not her Horsehead discovery!) in 1908, with the publication of the second Index Catalogue; she found no fewer than 59 gaseous nebulae on various Harvard photographs made in Massachusetts and Arequipa, Peru. In addition she discovered novae and hundreds of variable stars. But her seminal discovery of the Horsehead was not understood prior to the Waldee-Hazen paper of 1990. -- Stephen R. Waldee
What is the acual size of the horse head nebula in light years and miles?
A long standing problem in the study of planetary nebulae is that their distances are generally not well known. Many methods for estimating distances to planetary nebulae rely on making general assumptions, which may be very inaccurate for the object concerned. On this basis, the approximate distance is 3,300 light years
