Spots on Supergiant Star drive Spirals in Stellar Wind

Astronomers recently discovered that spots on the surface of a supergiant star are driving huge spiral structures in its stellar wind. Massive stars are responsible for producing the heavy elements that make up all life on Earth. At the end of their lives they scatter the material into interstellar space in catastrophic explosions ie supernovae – without these dramatic events, our solar system would never have formed.

Zeta Puppis is an evolved massive star known as a ‘supergiant’...
