International Ultraviolet Explorer was considered the most successful astronomical satellite ever. The human eye can perceive light with wavelengths between roughly 350 (violet) and 700 (red) nanometres. Ultraviolet light has wavelengths between roughly 10 nm and 350 nm. UV light can be harmful to human beings, and is strongly absorbed by the ozone layer. This makes it impossible to observe UV emission from astronomical objects from the ground. Many types of object emit copious quantities of UV radiation, though: the hottest and most massive stars in the universe can have surface temperatures high enough that the vast majority of their light is emitted
Flash-gas (petroleum) classified by their ability to absorb and emit radiation energy in atmosphere. This process of energy capture and release is what allows for the greenhouse effect, when energy trapped within the gas causes a resulting warming of the atmospheric temperature. Greenhouse gases are necessary for keeping our atmosphere warm enough to sustain life but also serve as a medium for over-heating to occur, a phenomenon referred to as global warming. GHGs are produced both directly and indirectly during many production phases of the oil and gas industry. It is estimated that 90% of GHG emissions from fossil fuels is due
