An Erupting Solar Prominence from SOHO
Explanation:
Our Sun is still very active.
In the year 2000, our Sun went though
Solar Maximum
, the time in its 11-year
cycle
where the most sunspots and explosive activities occur.
Sunspots
, the
>Solar Cycle, and
>solar prominences are all caused by the
Sun's changing magnetic field
.
Pictured above
is a
solar prominence
that
erupted
in 2002 July, throwing
>electrons and
>ions out into the
Solar System
.
The above image
was taken in the
>ultraviolet light emitted by a specific type of ionized
helium
, a common
element
on the
Sun
.
Particularly hot areas appear in white,
while relatively cool areas appear in red.
Our
>Sun should gradually quiet down until
>Solar Minimum occurs, and the Sun is most quiet.
No one can precisely predict when
>Solar Minimum will occur, although some
signs indicate
that it has started already!
