The gamma rays of the moon are shining brightly in these images from NASA's Fermi Telescope. Bright colors show a large number of gamma rays. This sequence shows how more months of exposure improved the outlook.

(CNN) – When it comes to brightness, the sun is hard to control. But in NASA's new images, the moon thanks to the bright-telescope that detects high-energy radiation.

NASA's Fermi Space Telescope allows us to see high-energy radiation called gamma rays, which gives the moon a sharp glow due to its gamma ray emission.

But it's not the gamma ray glow that scientists are really interested in – it's the brightness that cosmic rays say about other types of space radiation.

"The rays of the universe are often accelerated by some of the most powerful events in the universe, such as the exploding stars and the plane's blast waves," said Mario Nicola Mazziotta, a researcher at the Italian Institute of Nuclear Physics, Italy's National Institute of Nuclear Physics. Which studies the rays using a NASA image.

When cosmic rays hit the moon, they produce gamma ray emissions.

Therefore, from the point of view of the gamma ray telescope, the moon will be a nifty detector for cosmic ray particles.

Despite their electric charge, cosmic rays can reach the surface of the moon without pushing away because The moon lacks a magnetic field. Meanwhile, the sun's powerful magnetic field blocks many cosmic rays (except for the surprisingly energy-rich ones), creating less gamma ray emission to shine in binocular photos.

As NASA prepares to send humans back to the moon by 2024, it is important to study space radiation. The glow of these moon images suggests that astronauts will need protection from cosmic rays and the radiation they produce.

Interestingly, Fermi telescope images do not show the monthly phases of the Moon.

Scientist Francesco Loparco said, "Given these powers, the moon never goes through its menstrual cycle and will always look perfect."

But with the telescope, the brightness of the moon is changing over time. This is because the magnetic field of the Sun is cycled through different levels of intensity, which changes how many global rays that rise on the Moon.

Unlike a telescope, humans cannot see the shining gamma rays – so stop buying those moon glasses.
