Radiation from deep space is intensifying, affecting space weather and potential space travel

Ever since humanity’s first foray into space, our astronauts have had to contend with deep-space radiation. Scientists have done what they can to protect space voyagers and technology from exposure to cosmic rays. But, as new research has shown, that may not be enough: The radiation environment of space may be higher than previously conceived.

“The radiation dose rates from measurements obtained over the last four years exceeded trends from previous solar cycles by at least 30 percent, showing that the radiation environment is getting far more intense,” explained Nathan Schwadron, professor of physics at the University of New Hampshire.
