Abstract: We will present new views of the molecular gas distribution of the southern sky based on the CO surveys conducted by Nagoya University with the NANTEN 4-m millimeter-submillimeter wave telescope installed at the Las Campanas Observatory in Chile. The observations are carried out mainly in the 12CO, 13CO, and C18O (J=1--0) emissions at a beam size of ∼2.' 6. The survey toward the Galactic plane in 12CO covers almost 60 deg > l > 240 deg, -10 deg < b < 10 deg with grid spacings of 4' for |b| < 5 deg and of 8' for the remainder of the survey. This resulted in a number of detections of candidates for molecular supershells along the Galactic plane. In this contribution, we will briefly introduce the observational results by NANTEN focussing on the detection of the molecular supershells and on their role in triggering star formation in the Galaxy.
