Explanation:
Very recognizable stars of the northern
sky are a backdrop for calm waters in this moonlit sea and skyscape
off Cape Cod, Massachusetts.
Taken
on September 7, the photo also records a colorful display of
northern lights or
aurora
borealis triggered by a severe geomagnetic storm.
Visible
crossing the Sun, the giant solar active
region responsible, AR 2673, is much larger than planet Earth.
It has produced
the strongest flare of the current solar cycle and
and the Earth-directed coronal mass ejection
in the last few days.
