    Nebula

    A nebula is a distinct luminescent part of interstellar medium, which can consist of ionized, neutral, or molecular hydrogen and also cosmic dust. Nebulae are often star-forming regions, such as in the Pillars of Creation in the Eagle Nebula. In these regions, the formations of gas, dust, and other materials "clump" together to form denser regions, which attract further matter and eventually become dense enough to form stars. The remaining material is then thought to form planets and other planetary system objects. Most nebulae are of vast size; some are hundreds of light-years in diameter. A nebula that is visible to the human eye from Earth would appear larger, but no brighter, from close by. The Orion Nebula, the brightest nebula in the sky and occupying an area twice the angular diameter of the full Moon, can be viewed with the naked eye but was missed by early astronomers. Wikipedia

    Portion of the Carina Nebula. Around 150 AD, Ptolemy recorded, in books VII-VIII of his Almagest, five stars that appeared nebulous.He also noted a region of nebulosity between the constellations Ursa Major and Leo that was not associated with any star. [9] The first true nebula, as distinct from a star cluster, was mentioned by the Muslim Persian astronomer Abd al-Rahman al-Sufi in his Book ...

    4 days agoA nebula is a cloud of dust and gas in space. A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova.Other nebulae are regions where new stars are beginning to form.

    nebula, any of the various tenuous clouds of gas and dust that occur in interstellar space. The term was formerly applied to any object outside the solar system that had a diffuse appearance rather than a pointlike image, as in the case of a star.This definition, adopted at a time when very distant objects could not be resolved into great detail, unfortunately includes two unrelated classes of ...

    Oct 23, 2024Common Properties of Nebulae. Nebulae vary widely, but they share certain properties: Composition: Mostly hydrogen, with traces of helium, oxygen, nitrogen, and other elements. Size: Nebulae can span light-years across. Temperature: They range from cool molecular clouds, where stars are born, to hot, ionized regions surrounding young stars. Density: Nebulae are much less dense than the air on ...

    Oct 28, 2024How Do Stars Form in Nebulas? Stars are born in clouds of gas and dust. One such stellar nursery is the Orion Nebula, an enormous cloud of gas and dust many light-years across. Turbulence from deep within these clouds creates high density regions called knots. These knots contain sufficient mass that the gas and dust can begin to collapse from ...
