This
is a story about an incredibly challenging rescue that took place
on January 2nd, 2010, 250 miles off the shore of North Carolina.
Dennis Clements was on his way to the Caribbean when severe
weather struck and damaged his boat leaving him alone in the
middle of the frigid Atlantic Ocean. Miraculously, after an hour
floating in the cold water, he bumped into a life raft thrown by
the US Coast Guard and shortly after that he was pulled out by a
Navy rescue diver.

Dark
Filament
May

This
SDO close-up of a filament and active region, taken in extreme UV
light, shows a dark and elongated filament hovering above the
Sun’s surface (May 18, 2010). The bright regions beneath
it, which show where heating is going on in the magnetic field,
send up shafts of plasma that trace magnetic field lines emerging
from them. Filaments are cooler clouds of gas that are suspended
by tenuous magnetic fields. They are often unstable and commonly
erupt. This one is estimated to be at least 60 Earth diameters
long (about 500,000 miles).

dark regions show the site of evacuated material from the
eruption, and the large magnetic loops were formed during the
flare.

Has
pollen got you sneezing? Wondering what's causing that mysterious
afternoon haze? How do you find out what's in the air you are
breathing? For the thousands of people who visit the University
of Maryland Baltimore County's "Smog Blog" each day,
the answer is just a web click away. The Smog Bloggers combine
laser measurements of current air quality with NASA satellite
data to paint a daily picture of air pollution across the US.

These
images are whole-Sun maps of magnetic activity. They show 360
degrees of longitude in the Carrington coordinate system normally
used for solar observations. The map extent is from south pole to
north pole in an equal area projection. The solar equator and
each 60 degrees of longitude are marked.
