Cosmic dust —— dust in space—— includes intergalactic dust, interstellar dust, interplanetary dust and circumplanetary dust, which can cause not only extinction but also reddening for the remote background objects. Cosmic dust extinction plays a very important role in cosmological study. For example, the existence of cosmic...

10 09, 2014Chinese astronomers have reported the discovery of 28 candidate high-velocity stars, stars that whizz around so fast that they may escape from the Milky Way galaxy. The superfast moving stars are found at distances of up to one third ofthe distance to the center of our Milky Way, with speeds in excess of 300km/s.This sample is the ...

Prof. Baan is a distinguished expert in astronomical masers and ultra-luminous galaxies. As the first-author and co?author, he has more than 180 scientific articles in refereed ...
03 28, 2013After three years’ construction, the Shanghai 65-Meter Radio Telescope is close to its completion. In the second half of October, 2012, the mechanical structure, electrical system, network, control software of the telescope have been tested and they run smoothly. The test experiment was successfully carried out in the afternoon of...
10 27, 2012Chinese astronomers have made important progress in the study of the Milky Way structures. Using a simple bulge model, astronomers in Shanghai Astronomical Observatory (SHAO) confirmed and explained the existence of an intriguing X-shaped structure in the Milky Way bulge. This research was led by Dr. Zhao-Yu Li under the supervisio...
