This is at the same time coolheaded and horrifying . Cosmic electron beam are actually mote — diminutive protons and neutron , that shoot through space . They ’re too small to see , but astronauts may still be seeing them .
One of the things they do n’t severalise you about being an cosmonaut is the fact thatyou will see fiddling flashes of light . You will see them only once you ’re out of Earth ’s magnetosphere , which gives scientists a clue as to what may be causing the flashes . The magnetosphere is what protects us from many of the cosmic beam of light zooming through space .
“ Cosmic shaft of light ” are badly cite . They ’re not rays , they ’re tiny particles — usually single protons , but sometimes several protons stuck together ( otherwise known as a little nuclear core ) .
Obviously , these are much to small to be directly seen . investigator take a look at the question of what the spaceman were seeing up there . They came up withthree melodic theme . One was that the particles were interact with the optic mettle . The other was that they were instantly hitting the vision center of the brain .
The third theory is somehow creepier than either other option . Cherenkov radiationis a glow usually emitted by cloth around radioactive objects . Material , whatever it is , slows down photons . Only in a vacuity does low-cal travel at the “ upper of luminance ” . Light has a characteristic upper in dissimilar materials — glass , water , air travel , diamond — and within those materials , that speed can be exceeded . When the upper is exceeded , by particles pass off by the radioactive object , there is a kind of shower , or sonic gravy , of photons . The cloth emits lightsome . It ’s possible that what the astronauts are see is Cherenkov radiotherapy triggered by these particles passing through the vitrified witticism of their own eye . The luminousness is come from inside their eyeballs .
