can you still be hit by the UV rays even at night?

Question

UV rays come frome the sun, right? if the moon is reflecting the sun's light, even at night, can you still be touched by the UV rays while walking at night?

Answer 1

you shouldnt if the sun is down... UV rays are from the sun directly.. if the moon reflects off the sun's light at night, there might be a small chance that you will be touched by these UV rays.. gosh, we're making it seem like a bug or something drastic. lol.

Answer 2

UV rays are just light that is more violet than violet light, and your eyes cannot see it. The Sun does generate UV, but so do the stars, which are just very distant suns. Of course starlight is very dim compared to sunlight, so you don't get hit by enough UV light from the stars to cause any effects, but your are still getting some microscopic amount. And some does get reflected by the Moon, so you might get a little from that too. But the amount is too small to have any effects. You cannot get a starburn or a moonburn like you can a sunburn, just like you cannot warm up by standing in the moonlight or starlight on a cold day.

Answer 3

When these highest-energy cosmic rays strike the Earth's atmosphere, they produce low-energy UV radiation in the NIGHTGLOW range. A proposed NASA satellite mission called OWL (Orbiting Wide-angle Light-collectors) would detect this radiation from a low-earth orbit and help us understand their origins. The highest-energy cosmic rays are rare, and a device such as OWL is needed to search for them simultaneously over wide stretches of the atmosphere, as wide as 400,000 square miles.

NIGHTGLOW will lay the groundwork for OWL by precisely measuring the background UV radiation at nighttime. When an energetic cosmic ray strikes, OWL would be able to differentiate between the cosmic ray-induced UV radiation and ordinary background radiation. NIGHTGLOW itself could not search for such rare cosmic rays because its field of view at any given time is less than a square mile.
So your answer to this question would be YES but with a lesser effect.

Answer 4

Not at all .. what moon reflects is scattered light .. UV rays have to come directly ..

Answer 5

Yes. We have the background radiation phenomena. UV and other forms of radiation are do emitted at night by the moon, stars and other sources!

Answer 6

yes. Light is also infered ligh which means that its is warm or hot. So it takes 8 minutes for light to travel from the sun to the earth.

Answer 7

There no such rays at night.

Answer 8

No, I don't think so.
