Te­le­scope ob­tains data on 7 mil­lion stars

China Daily (Canada) - - NEWS CAPSULE -

A Chi­nese te­le­scope has col­lected data on more than 7 mil­lion stars, ex­ceed­ing the sum of all ex­ist­ing spec­tro­scopic data on stars and mak­ing it the world’s largest data­base in the field.

The Guo Shou­jing te­le­scope, named af­ter a 13th-cen­tury Chi­nese as­tronomer, is op­er­ated by the Na­tional Astro­nom­i­cal Ob­ser­va­to­ries un­der the Chi­nese Academy of Sciences (CAS), which re­leased the find­ings.

The te­le­scope has been in use since 2012. It is the world’s first large-area te­le­scope that can ob­serve the spec­tra of 4,000 stars at a time.

“Data are para­mount for astro­nom­i­cal stud­ies,” said Liu Chao, a fel­low re­searcher with the na­tional ob­ser­va­to­ries.

In 2014, sci­en­tists used the te­le­scope to dis­cover a hy­per­ve­loc­ity star, which are stars that can travel at high speeds to es­cape the grav­ity of a gal­axy.
