Milky Way Center Lacking Stars

Posted by on Tuesday, August 2, 2016

A new study has shown that the center of the Milky Way is entirely lacking young stars.

There are billions of stars within the Milky Way. Our Sun about 26,000 light-years from its center.

Researchers used an analysis of near-infrared observations made with a Japanese-South African telescope located in South Africa. They found almost no Cepheids in a huge region stretching for thousands of light years from the core of the galaxy.

Cepheids is a type of star that pulsates radially, varying in both diameter and temperature and producing changes in brightness with a well-defined stable period and amplitude.

There is an area extending out to 8,000 light years from the center that is nearly empty.
