The most super-charged particles in the universe—cosmic rays is now being inspected by a giant balloon which is taller than the football field.

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 solar system."
