Astronomers Put Forward New Theory of Galaxy Formation

摘要

How and when did galaxies form? How and when did stars form in these island-like universes? These questions are still posing a considerable challenge to present-day astronomers. An international team of astronomers, including CAS researchers from the China's National Astronomical Observatories, presents new convincing answers to such fundamental questions. For this, they rely on an extensive set of observations of galaxies taken with several space- and ground-based telescopes. In particular, they used over a two-year period, several instruments on Very Large Telescope-of the European Southern Observatory (ESO).
