The researchers at the University Of Hawaii Institute Of Technology (IFA) have been studying the solar corona.
It is an outermost atmosphere of the sun that expands into interplanetary space.
This stream of charged particles that have been radiating from the surface of the Sun is called the Solar wind and it expands to fill the entire Solar system.
The corona has been most easily seen during a total solar eclipse.
When the moon is directly between the Earth and Sun which blocks the bright surface of the Sun is the total solar eclipse.
