I believe it is about time I state another fact about space. If you have any topics you would like me to offer information for, do let me know! Nebulae. Giant clouds of gas, cosmic dust and a vast number of other material components. Did you know there are four different major types? For now, I shall focus on Diffuse Nebulae. A majority of discovered nebulae fall under this type. These can be further separated into three subtypes, based on their visibility: Emission Nebulae glow and provide their own light; Reflection Nebulae are illuminated through the reflection of nearby stars and finally Dark Nebulae absorb or block visible wavelengths of light! One of the most famous examples of Diffuse Nebula on Earth is NGC 2174 or, colloquially, the Monkey Head Nebula. This example is found approximately 6,400 light-years away from Earth!
