Hot blue star

Its story

In the direction of Cygnus lies a blue B-type star, intensely hot and supergiant by nature. Its distance, estimated in hundreds of thousands of light-years, suggests it belongs more to the halo than to the galactic disc: its light reaches us after a millennial journey that began long before any human civilisation. It is a bluish beacon linking the celestial swan with remote extragalactic regions.
