HOW BIG IS ANTARES?

Reported by Lee Cavendish

The night sky, especially when viewed from an area with low to no light pollution, can reveal a beautiful array of celestial gems - twinkling stars that generations before have marvelled at. The difference between then and now is that our generation has the capability to map these stars with precision. New research has taken this to a whole new level by mapping the famous star Antares, learning more about its atmosphere and how this can be applied to other red supergiant stars.
