Explanation:
Here is one of the sharper views of the Sun ever taken.
This stunning image shows remarkable details of a dark
sunspot across the image bottom
and numerous
boiling granules
which appear like
kernels of corn
across the top.
Taken in 2002,
the picture was made using the
Swedish Solar Telescope operating
on the Canary Island of La Palma.
The high resolution image was achieved using sophisticated
adaptive optics, digital
image stacking, and other processing techniques to counter the
blurring effect of Earth's
atmosphere.
Currently a sunspot group is crossing the Sun that is so large it can be
easily seen by the
cautious observer
even without magnification.
