July 2020 marks 50 years since the astronomical discovery of interstellar carbon monoxide (CO)  and 51 years since the detection of the first polyatomic molecules ammonia (NH3) , water (H2O)  and formaldehyde (H2CO)  at radio frequencies. These discoveries fundamentally altered our view of interstellar space, and astronomical observations continue to provide new opportunities for chemical discovery. Astronomical instrumentation has improved substantially since the early days of molecular astrophysics, and broadband, high spectral resolution surveys are now possible in frequencies ranging from 1 GHz to 10 THz, leading to a plethora of new molecule detections and an improved understanding of the formation of molecular material in astronomical environments . In addition, the data quality coming from these astronomical broadband surveys routinely rivals their laboratory-based counterparts – not only in achieved signal-to-noise ratio but also in terms of the complexity of the mixtures detected. Observations using these remote sensing techniques have characterized the nitrogen content in the atmosphere of Titan , detected new large carbon-bearing molecules in cold dark clouds that may carry the majority of the C-budget in the universe  and been responsible for the detection of the largest atomic species ever seen in the early universe . In addition, broadband molecular line data taken with interferometric arrays allow one to investigate the distribution and morphology of molecular material in astronomical environments, thereby providing a comprehensive chemical picture of the universe. In this special issue of the Journal of Molecular Spectroscopy, we encourage submission of original research papers that highlight laboratory studies of astronomical interest, spectral line observations of astronomical sources, and opportunities that may be possible with the next generation of astronomical facilities. This Special Issue is dedicated to Dr. Francis (Frank) J. Lovas who was one of the driving forces of the microwave spectroscopy group at the National Institute of Standards and Technology (NIST).
