They imagine that the Moon was brighter than the Sun. Well, according to the image captured by the telescope NASA Fermi, right, except that our eyes are not able to record that awesome situation.
The American space agency has revealed that if human eyes could see high-energy radiation called gamma rays, the Moon would seem to shine more than the brightest star in our system.
But why does NASA analyze these types of images? According to the team of scientists who have analyzed the last 10 years through the gamma ray telescope, the brightness of the moon's gamma rays allows us to better understand another type of radiation from space: fast-moving particles called cosmic rays.
Cosmic rays are mostly protons accelerated by some of the most energetic phenomena of the universe. Because the particles have an electric charge, they are strongly influenced by magnetic fields, which are missing from the Moon.
But it was not all that revealed the impressive image. According to researchers from the National Institute of Nuclear Physics in Bari, receiving the cosmic rays – even at low energy – the Moon turns into a practical space-based particle detector.
The researchers collected gamma-ray data with energies greater than 31 million volts of electrons, over 10 million times greater than the energy of visible light.
The data that have been organized over time have also revealed that if we could see the gamma rays we would never see the monthly cycles of the moon, that is we would always see it full.
