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!
