The study of the universe is ever going and the further we go, the newer things we find. In recent research, scientists have found traces of a novel molecule in the atmosphere of Titan, Saturn’s largest moon. This molecule has never been found in any other atmosphere and it is very rare, so much so that NASA says even many chemists won’t know about it. The simple carbon-based molecule is known as cyclopropenylidene, or C3H2 and can form the basis of many complex compounds which can lead to or help in forming life. The molecule is made up of carbon and hydrogen, and its simple structure means that it can easily react with other chemical compounds. And this is why the molecule has never been found in any other atmosphere. The American space agency says that “astronomers have so far found C3H2 only in clouds of gas and dust that float between star systems — in other words, regions too cold and diffuse to facilitate many chemical reactions".
