摘要

A new shell-type faint radio Supernova Remnant (SNR) has been discovered by CAS astronomer TIAN Wenwu and his Canadian colleagues, as reported in the April 3 issue of Astronomy and Astrophysics.rnNamed SNR G 108.2-0.6, the remnant is about ten thousand light years away from the Earth with an expansion diameter of some 180 light years. It is also of the lowest surface brightness among all known remnants, according to Dr. Tian, a researcher from the CAS-affiliatedrnNational Astronomical Observatories and first author of the paper.
