My Favorite APOD Nebula Images
There are numerous mysteries contained within the Cosmos that have yet to fully be analyzed and appreciated. The unique events that transpire within the Universe everyday are unbelievably remarkable and captivating. Hidden within the immense ocean of stars we see every night lays an even more incredible spectacle in the form of Nebulae. The paragraphs that ensue will delve into the creation of Nebulae, and the many intriguing aspects of the most visually appealing amongst these particular phenomena.
The Astronomy Picture of the Day (APOD) website features many spectacular images of the Universe and the phenomena contained within it. Among this considerable collection of pictures there are several diverse photographs of nebulae; such as, The Great Carina Nebula, The Red Spider Planetary Nebula, The Ring Nebula, The Horsehead Nebula, The Crab Nebula and The Butterfly Nebula. The word, nebula, itself comes from the Greek word for cloud, and is defined as a stellar nursery made of clouds of dust and hydrogen gas.
Furthermore, there are five main types of nebulae; they include emission, reflection, planetary, dark and supernova remnants. Each type appears in a vast array of shapes, sizes and form in different ways. The unique appearance of each nebula depends on temperature, density and how the dust is spatially arranged with respect to the viewer. Although all nebulae are forms of interstellar matter some of them formed from the death of stars while others formed from atoms and simply reflect the light from the nearby stars.
The first nebula, to be highlighted, is The Great Carina Nebula, or NGC 3372, which is found approximately 7,500 light-years away from earth and is easily observed with the unaid...
