Not exact matches
Although Proxima Centauri's dimness
provides the planet with a balmy climate, the star is prone to outbursts of harsh X-ray and ultraviolet
radiation, which could damage any chance of life on the planet — X-rays hit the surface 400 times more often than those
from the
sun pummel Earth.
Btw, if anyone can
provide any evidence of more than 10 watts per square meter of any kind
radiation from the
Sun [or
from anywhere] other than the energy emitting
from the
Sun in wavelength in the range 250 to 2500 nm and intersecting the earth surface, I would find this very fascinating.
Earth's atmosphere also plays a vital role in regulating the temperature by
providing a blanket of gases that not only protects us
from excessive heat and harmful
radiation from the
sun, but also traps heat rising
from the Earth's interior, keeping us warm.
The theory is that the Ozone Hole, by allowing more of the UV component of the
Sun's incoming
radiation to make it down to low altitude rather than being absorbed in the stratosphere is
providing an incremental energy increase to drive the strength of the SAM, and thus the degree to which Antarctica is isolated
from more global weather influences.
The
Sun's
radiation transports, or emits, short - wave electro - magnetic
radiation away and thus avoids «a big bang» --(There may also be back
radiation from planets etc.
provided the radiative forces are strong enough to reach the
Sun) On a smaller scale the same «Energy Transport System» or radiative principles work here on Earth too.
Notice that the Earth System mean temperature I had to use to
provide 240 Watts / m ^ 2 of
radiation to Space to balance the input absorbed
from by the Earth System
from the
Sun was 255 K. However, the actual mean temperature at the Surface is closer to 288 K.
