**Nebula**
The term #0excludeGlossary has a fascinating etymology, tracing back to the Latin word for #1excludeGlossary or #2excludeGlossary Historically, it was used to describe any diffuse astronomical object, but its meaning has since narrowed to refer to interstellar clouds of gas and dust. In the cannabis world, Nebula is a strain that mirrors the ethereal beauty of its astronomical counterpart. Known for its sweet, fruity aroma and potent effects, the Nebula strain is cherished for its ability to elevate mood and inspire creativity. As the cannabis industry continues to expand, Nebula stands out as a strain that offers a unique blend of relaxation and euphoria, making it a popular choice for those seeking a cosmic escape. With its roots in both the stars and the earth, Nebula is a testament to the ever-evolving nature of language and culture. Whether you’re exploring the universe or the world of cannabis, Nebula offers a journey that’s as enlightening as it is enjoyable. [Source: Harvard, Weedmaps]
A nebula (Latin for 'cloud, fog'; pl. nebulae or nebulas) 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 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. Although denser than the space surrounding them, most nebulae are far less dense than any vacuum created on Earth (105 to 107 molecules per cubic centimeter) – a nebular cloud the size of the Earth would have a total mass of only a few kilograms. Earth's air has a density of approximately 1019 molecules per cubic centimeter; by contrast, the densest nebulae can have densities of 104 molecules per cubic centimeter. Many nebulae are visible due to fluorescence caused by embedded hot stars, while others are so diffused that they can be detected only with long exposures and special filters. Some nebulae are variably illuminated by T Tauri variable stars.
Originally, the term "nebula" was used to describe any diffused astronomical object, including galaxies beyond the Milky Way. The Andromeda Galaxy, for instance, was once referred to as the Andromeda Nebula (and spiral galaxies in general as "spiral nebulae") before the true nature of galaxies was confirmed in the early 20th century by Vesto Slipher, Edwin Hubble, and others. Edwin Hubble discovered that most nebulae are associated with stars and illuminated by starlight. He also helped categorize nebulae based on the type of light spectra they produced.
