Japanese satellite Hinode discovers two huge holes in sun's magnetic field Local Japanese News In English
A Japanese satellite has captured images showing two huge holes in the Sun which are blasting solar material into space.
Known as "coronal holes" these gaps in the Sun's magnetic field allow gas to escape into space through the star's super-hot outer atmosphere where they become the "solar wind".
Solar winds stream from the holes hitting the earth at an average speed of 400 kilometres per second contributing to auroral displays and in more extreme cases creating solar storms. (news.com.au)
