The Moon is shining brighter than the Sun — and that is dangerous
- The Moon outshines the Sun as cosmic rays bounce off its surface creating gamma radiation.
- They aren’t visible to the naked eye but were spotted using NASA’s
Fermi Gamma Ray Telescope.
- Gamma rays may make the Moon shine all year around but they’re fatal to lunar explorers who plan to land on the surface.
All it takes for that to happen is radiation, gamma rays and National Aeronautics and Space Organisation’s ( NASA) Fermi Gamma Ray Space Telescope.
Unlike the Sun, the Moon doesn’t have a protective magnetic field around itself. All the cosmic rays, which are basically high energy radiation, slam right onto the lunar surface.
Cosmic rays are mostly protons accelerated by some of the most energetic phenomena in the universe, like the blast waves of exploding stars and jets produced when matter falls into black holes.
The result is an explosion of gamma rays, which aren’t visible to the naked eye.
"Seen at these energies, the Moon would never go through its monthly cycle of phases and would always look full," said Francesco Laparco, a researcher at Italy’s National Institute for Nuclear Physics, in a statement to NASA.
Why care about gamma rays?
Studying the amount of radiation on the Moon can help space agencies, like NASA which plans to send astronauts to space in 2024, have better protection in place.
Apollo astronauts are already paying the price with higher mortality rate than average due to heart diseases. And this is no ordinary heart disease, it was brought on by exposure to deep space radiation according to a paper published in Scientific Reports.
And, it’s because of gamma radiation that scientists are wondering whether it will ever be possible to build a safe habitat for humans off-the-planet — ever.
