Diverse theories range from cosmic deliveries of organic compounds to local synthesis of amino acids in the Primordial Soup of a young Earth. Some theories settle with a compromise between the two. The most popular idea suggests an Earth bombarded by comets and asteroids which brought building blocks of life onto the planet. This notion hinges on one important premise: that there are organic compounds in outer space. As telescope technologies have vastly diversified since Galileo's age, we have come to analyze specific wavelengths of light that characterize the various phenomena of space, like supernovas and solar activities. Recently, scientists have developed a technique to analyze new type of data; namely, the chemical composition of space to detect organic molecules. The astrochemists - the combined profession of an astronomer and a chemist - uses radio frequencies to classify various molecules, which inherently have different atomic compositions and structures which alter radio waves that reach the telescope. Astronomers turned their focus to one of the giant gas clouds near the center of the galaxy to analyze the identities of molecules that compose it. By analyzing the radio frequencies gathered by the Green Bank Telescope in West Virginia, astrochemists determined that a molecule called cyanomethanimine is present in the cloud of gases. Anthony Remijan, a researcher at the National Radio Astronomy Observatory, explained that cyanomethanimine is a precursor of adenin, one of the four building blocks of DNA. Scientists believe that the detection of cyanomethanimine encourages the theory that there are organic compounds in space. In addition to cyanomethanimine, scientists also found a compound called ethanamine which is a key component in the formation of alanine, an amino acid that is crucial in genetic coding.
