Forest of Molecular Signals in Star Forming Galaxy
Astronomers found a rich molecular reservoir in the heart of an active star-forming galaxy with the Atacama Large Millimeter/submillimeter Array (ALMA). Among eight clouds identified at the center of the galaxy NGC 253, one exhibits very complex chemical composition, while in the other clouds many signals are missing. This chemical richness and diversity shed light on the nature of the baby boom galaxy.

The helium explosion at the surface sets out the final journey of a dying star
An international astronomical team led by Ji-an Jiang, a graduate student of the University of Tokyo, and Mamoru Doi (U-Tokyo) has found the evidence that the brightest stellar explosions in our universe could be triggered by the helium nuclear explosion at the surface of a white dwarf (star), by carrying out survey observations with the wide-field camera mounted on the 8.2-m Subaru telescope, the Hyper Suprime-Cam. This study was reported in Nature published on Oct. 5, 2017 (Japanese Standard Time).
