telescope, but was not sharp like stars or planets" (Nebulae - Fuzzy Patches in Space, 2002). It was the 18th century French astronomer Charles Messier that first published  a catalogue of these objects so that he and other astronomers would not confuse them with comets (Nebulae - Fuzzy Patches in Space, 2002). Examination of his work by  later day scientists reveals that on some account Messier was not accurate, but indeed his contribution was significant as a starting point for nebulae identification and recording (Nebulae - Fuzzy  Patches in Space, 2002). Nebulae "" refers to clouds of interstellar dust and gas within our own galaxy made visible by their interaction with nearby stars or star  remnants" (Nebulae - Fuzzy Patches in Space, 2002). There are four main types of nebulae in our solar system (Nebulae - Fuzzy Patches in Space, 2002). They are:  Emission Nebulae, Reflection Nebulae, Planetary Nebulae, and Supernova Nebulae (Nebulae - Fuzzy Patches in Space, 2002). Each one of these types has a unique character (Nebulae - Fuzzy Patches  in Space, 2002). The word nebulae is derived from a word meaning clouds, and essentially, a nebulae is a cloud  of gas and dust floating in space (Nebulae - Cosmic Clouds, 2002). Nebulae are considered a building block of the universe and contain the same elements as stars and  solar systems (Nebulae - Cosmic Clouds, 2002). Additionally, they are very beautiful and typically glow in the sky (Nebulae - Cosmic Clouds, 2002). Typically, nebulae are composed of 90%  hydrogen, 10% helium, and 0.1% heavy elements such as carbon, nitrogen, magnesium, potassium, calcium, iron (Nebulae - Cosmic Clouds, 2002). It is interesting to note that nebulae are among
