Cold bed in the Sun


Observations with the infrared Herschel Space Telescope discovered the star Alpha Centauri A strange "cold bed", exactly the same as that of our sun.

Our star is composed of six layers: the core, where fusion reactions occur, areas of radioactive transfer, convective zone, photosphere, chromospheres and corona.
