The work «builds on a notable amount of literature showing that
space radiation produces negative consequences on brain and behavior,» says Amelia Eisch, a neuroscientist at the University of Texas Southwestern Medicine Dallas.

Outer
space may look mostly empty, but it's actually packed with cosmic
radiation — gamma rays and charged particles
produced by exploding stars, black holes and other violent astrophysical phenomena.
To conduct the new study, rats were first trained for the tests and then taken to Brookhaven National Laboratory on Long Island in Upton, N.Y., where a collider
produces the high - energy proton and heavy ion
radiation particles that normally occur in
space.
Asteroids also contain an abundance of water, which, aside from serving as hydration during
space travel, could be used as a shield to protect spaceships from the sun's
radiation or to
produce hydrogen - and oxygen - based rocket fuels.
At the same time the surface and the atmosphere emit infrared
radiation back to
space, which
produces cooling.
Instead of dissipating into
space, the infrared
radiation that is absorbed by atmospheric water vapor or carbon dioxide
produces heating, which in turn makes the earths surface warmer.
But Alex Dessler, a
space physicist at the University of Arizona, Tucson, says the same area of the planet also
produces unusual radio signals, flares of ultraviolet light, and high levels of infrared
radiation and even seems to be correlated with a patch in Jupiter's magnetosphere that pumps out high - energy electrons.
It was the first cosmic event in history to be witnessed via both traditional telescopes, which can observe electromagnetic
radiation like gamma rays, and gravitational wave detectors, which sense the wrinkles in
space - time
produced by distant cataclysms.
was 30 degrees Kelvin); whereas Eddington in 1926 had already calculated that the «temperature of
space»
produced by the
radiation of starlight would be found to be 3 degrees Kelvin.»
«The big bang made no quantitative prediction that the «background»
radiation would have a temperature of 3 degrees Kelvin (in fact its initial prediction [by George Gamow in 1946] was 30 degrees Kelvin); whereas Eddington in 1926 had already calculated that the «temperature of
space»
produced by the
radiation of starlight would be found to be 3 degrees Kelvin.»
The fifth gravitational wave event (GW170817), detected in mid-August 2017, was probably even more important than the first detection because it was the first one whose source also
produced electromagnetic
radiation we could observe with ground and
space - based telescopes.
Such emission of infrared
radiation to
space produces substantial cooling... think of a refrigerator coil at the surface.
Large solar storms, such as from flares and CMEs, can
produce lethal
radiation environments on the Moon or in interplanetary
space.
Physics says the energy into a system must equal the energy out once in balance, The heat in the oceans is what must be there to
produce enough heat
radiation out to
space through the air / GHG blanket.
And cumulus clouds not only reflect solar
radiation back into
space but also
produce rain.
Added methane reduces heat
radiation to
space, amplifying the warming effect of carbon dioxide
produced by burning fossil fuels.
I believe that if in the vacuum of
space you place a blackbody object with (a) a constant (i.e., unchanging energy per unit time) internal thermal energy source, and (b) internal / surface thermal conduction properties such that independent of how energy enters the blackbody, the surface temperature of the blackbody is everywhere the same and you place that object in cold
space (no background thermal
radiation of any kind), eventually the object will come to a steady state condition — i.e., the object will eventually radiate energy to
space at a rate equal to the rate of energy
produced by the internal energy source.
