most super-charged particles in the
universe—cosmic rays is now
being inspected by a giant balloon
which is taller than the football
Researchers from Sweden who belong
to University of Delaware have set
afloat the balloon, which is 396 feet
tall and 459 feet in diameter when
fully inflated, last week from Esrange
Space Center near Kiruna in Sweden
in the Arctic Circle.
The Balloon is currently flying at
a speed of more than 40 Knots and
at an altitude of nearly 27 miles.
The level of solar activity rises
and falls over a period of approximately
11 years and influence cosmic ray
intensity. And as solar activity rises,
cosmic ray activity decreases.
The data from the balloon will be
used to study solar modulation, the
variation in cosmic ray intensity
is correlated with solar activity.
One of the researchers said "We're
working to better understand how the
sun's changing magnetic field affects
cosmic ray propagation through the
