Astronomy in the information era

In the 21st century, astronomy steps into the era of big data and information science, and takes on a new look. The questions about the origin of the universe and how to relate to information science are issues yet to be solved for astronomers. Although some achievements have been made, in this new age astronomers need to understand artificial intelligence and cooperate with experts from other fields or enterprises, and foster a new big-data oriented generation to compose together the beautiful chapters of astronomy.
