Astronomy is the almighty science. "It got physics started by showing the beautiful simplicity of the motion of stars and planets" (Feynman Lecture I. 3-6). Now it is beginning to engulf chemistry by showing exquisite spectra! It has been observationally established that hydrogen in the Universe is more molecular than atomic, over 100 molecules exist abundantly in interstellar space, and molecules are essential for star formation. We here discuss some recent developments starting from the most fundamental H3+, which plays the pivotal role in interstellar chemistry, to the diffuse interstellar bands, an enigma for astronomers for nearly 100 years, whose carriers are yet to be identified but are surely complex organic molecules.
