ALMA is demonstrating its power in solving various mysteries of the universe. In particular, the mystery of how galaxies were born and evolved in the 13.8 billion year history of the universe is a major theme in modern astronomy. ALMA's high sensitivity and resolution have made it possible to observe galaxies that exist in the universe more than 13 billion years in the past, and are gradually revealing the appearance of the early universe. It has also made it possible to examine in more detail than ever before the gas clouds that can be called the factories of stars in galaxies that exist in the present universe. We will introduce in an easy-to-understand manner the cutting edge of research that is unraveling the evolution of the universe through the appearance of various galaxies, such as galaxies that are explosively forming stars, galaxies that are currently merging, and galaxies that are strongly influenced by supermassive black holes. #ALMA #Space #Astronomy #Planet #BlackHole
