RCW 58

Hi,

This is an image of RCW 58. It is a ring nebula about 13,000 light years away in the constellation Carina. It surrounds and originates from Wolf-Rayet star WR40, which is the bright blue star in the center of the nebula. Wolf-Rayet stars are massive (up to 20 solar masses), hot (30,000 t0 200,000 degrees Kelvin) stars that produce very strong solar winds. These solar winds ionize the surrounding gas producing the nebula. It is estimated this nebula is expanding at a rate of 87 km/s.

Comments and suggestions welcomed.
