Hence, the stars are only visible to the plain eye during the night time. They become invisible in the day because of the brightness of the sun rays. Since the sun is so bright, it contrasts with the brightness of the stars during the day. Having realised his error, he ponders why it's so rate to see — or at any rate to notice — the moon in the daytime sky. b) Stars are in the sky both day and night. When we "see" stars, what we actually see is the light they sent out years ago. But stars are in the sky both day and night. The effect called "scattering" that takes place in the earth's atmosphere is what prevents us from seeing other star's during the daytime. Seeing the dim light of a distant star in the blanket of photons from our Sun becomes as difficult as spotting a single snowflake in a blizzard. Why, then, do photos of things in space not contain stars? In the daytime we see the sun shine. So, yes, on Earth, the atmosphere is in fact the problem, because of Rayleigh Scattering. Why can't we see stars in the daytime? In space this doesn't happen, so you can see stars during the "day" (which is all the time). We can only see them at night because during the day, even though the light they sent out is still hitting the earth, the sun puts out so much more light that it drowns out the other stars. Which information from the passage shows this is true? During the night, when the sun's rays are blocked by the other side of the earth, it is possible to see the faint light of the stars shining in space. And how come dimly lit worlds like Pluto look so bright in space photos? Answer by Rebecca Pitts , MS in astronomy, working toward PhD, on Quora : There are a few questions that we get all the time at The Planetary Society. What color is your sky during the day? When the sun is up, the blue color in sunlight gets scattered all over the atmosphere, turning the sky the familiar bright blue color. Those stars are made of burning gases. I always thought sunlight would bounce off the particles in the air, thus illuminating them. Why Can't Stars Be Seen In Moon, Space Photos? The best way to appreciate that is to watch a sunrise this week and keep an eye on the moon; it will dramatically fade as the sun rises, though look carefully and you can often see it during the day.

It is bright and the atmosphere refracts and scatters the light from it so that the other stars can't be seen. during the day is very simple: the atmosphere is too bright. originally appeared on Quora-the place to gain and share knowledge, empowering people to learn from others and better understand the world. "The stars are nowhere near as bright as the blue sky during the day, but the moon is approximately as bright in reflected sunlight as the sky during the day, and that's why we can see the moon during the day, but not the stars during the day," O'Meara said. How is it that we can see the brightest object in the night sky when the Sun is still beaming overhead? First, there’s the sun, our nearest star, but observing it directly is dangerous without using the proper shields and equipment. Stars and planets do not actually disappear they just become unseen in the daytime.
