Astronomers have traced the source of mysterious high-energy X-rays and gamma rays in space to a little known star cluster in the Milky Way. IE 11 is not supported.

The scientists looked at stars in the Perseus stellar cluster — a region with a high concentration of stars, particularly red supergiants, located around 7,500 light-years from the solar system ...

Red-supergiant supernova images reveal secrets of an earlier universe. An international research team led by the University of Minnesota Twin Cities has measured the size of a star dating back 2 ...

Using a massive galaxy cluster as a magnifying lens, ... After burning out all its nuclear fuel, the red supergiant star, 11.5 billion light years away, exploded in a supernova.
