This development, while sudden, is not unexpected. Cosmic rays from deep space are repelled by solar activity; when one goes up, the other goes down. Since 2021, Solar Cycle 25 has roared to life<\/a> faster than forecasters expected. The onset of the new solar cycle has naturally led to a decrease in cosmic radiation reaching Earth.<\/p>\n\n\n\n

To many readers this may sound counterintuitive. After all, don\u2019t solar flares produce<\/em> radiation? Yes, but most high-energy radiation doesn\u2019t come from the sun; it comes from deep space. Every day galactic cosmic rays<\/a> from distant supernova explosions pass through the Solar System. When they hit the top of Earth\u2019s atmosphere, they create a secondary spray of radiation, which we measure<\/a> using sensors onboard our balloons.<\/p>\n\n\n\n

The sun makes it more difficult for these cosmic rays to reach Earth. Simply put, when the sun is active, its magnetic field gets stronger and more tangled. Cosmic rays have trouble penetrating the magnetic thicket. Also, individual CMEs sweep aside cosmic rays, causing sharp reductions called \u201cForbush Decreases<\/a>.\u201d The two effects blend together to bring daily radiation levels down.<\/p>\n\n\n\n

There is considerable interest in atmospheric cosmic rays. Climate scientists are engaged in a lively debate about whether or not cosmic rays affect cloud cover. (The consensus seems to be mostly not<\/a>.) Cosmic rays also penetrate aircraft, boosting the risk of cancer among frequent fliers and flight crews.<\/p>\n\n\n\n

Solar Maximum is expected in 2025, so the downward trend in cosmic radiation should continue for years to come.\u00a0How low will it go? Stay tuned for updates.<\/p>\n\n\n\n
