Brazil seeks to measure energy from solar explosions

Sao Paulo, April 5 (EFE).- A team of Brazilian scientists plan to use a pair of stratospheric balloons to study the energy produced by explosions on the Sun, the head of the project said.

The specially equipped balloons have to reach the stratosphere - 40 kilometers (25 miles) above the Earth's surface - because the frequencies the researchers want to study cannot penetrate the atmosphere, Pierre Kauffmann told Efe.

Balloons represent a less costly alternative to satellites, according to Kauffmann, a scientist with the Center for Radioastronomy and Astrophysics at Sao Paulo's Universidade Presbiteriana Mackenzie.

The first balloon flight, tentatively scheduled for the summer of 2014, will pass over Russia.
