During the job the stars are still there, you justcan"t watch them because the sky is therefore bright. Forexample, it"s a lot much easier to check out the glow of acandle in the dark than in the light. It isalways tough to sense tiny changes come somethingthat is already large to start with. Because that example,in a loud room you probably can"t hear a drippingfaucet, however when every little thing else is quiet climate youcan hear the drip, also though the dripping hasn"tgotten any louder. That is just less complicated to hearsomething soft in a quiet background, than it isto hear something soft in a noisy background. In the same method it"s much easier to watch the dimstarlight with a dark background 보다 it is come seethe exact same dim starlight ~ above a bright background.

Answer 2:

Try noticing the sky at night throughout the nextmonth.Compare how countless stars you deserve to see now, if moon is not up (until around midnight orlater), come a couple of weeks from now when the moon isfull again. Now imagine having the sunlight in the skyinstead of the complete moon. How numerous stars do youthink girlfriend should have the ability to see?You couldalso clock the skies as the sun is setting. Together thesky begins to darken, when can you very first seestars? exactly how bright does the sky seem come be in ~ thistime when contrasted with daytime? once the skies isfully dark, exactly how bright are the very first stars youcould see contrasted to the rest of the stars in thesky?

Answer 3:

The reason that girlfriend cannot watch stars during thedaytime is that the sun"s beam overpower the faintlight we view from the stars. Throughout the night,when the sun"s rays space blocked by the various other sideof the earth, it is feasible to watch the faintlight of the stars shining in space. Girlfriend canwatch this shift if you clock the sunset on aclear night, as the sun"s rays end up being fainter andfainter (and it i do not care dawn on the various other side ofthe earth), you can begin to view the very first hint ofthe brightest stars. You will also notice that,generally speaking, the an initial stars to appear willbe those farthest away from the setup sun (wherethe skies is darkest at the time).Hope thathelps!

Answer 4:

This question have the right to be partly answered by severaleffects. First, the person eye is perceptible tolight end an enormous selection of intensities.Typical "bright" stars space actually very dimcompared come the brightness the the sun -- about atrillion 10^12 time dimmer. The brightness ofobjects illuminated through the sun frequently 10 come 100times dimmer 보다 it is -- yet that still makesthe an enormous problem for the eye. (It has atleast 2 mechanisms for light accommodation-- theiris which straightforward stops a fraction of the lightlike a camera lens, and chemical transforms whichenhance the cells particular to night vision. --this takes part 10 come 20 minutes and also unless youwalk quickly from dim to bright or angry versa youwon"t notification it.) for this reason the very first problem is thatyour eye -- to permit you to see, will alleviate itssensitivity when there is shining lightpresent.Secondly, the environment of theearth has lots of fine particles of dust i m sorry areso tiny they never settle come the ground. Thesedust particles scatter a small component of the lightfrom the sunlight in random directions, and themechanism for scattering works better for shorter(bluer) wavelengths. This is why the sky is blueand why the sun appears to redden together it sets -- ithas a much longer path in the air -- so more of theblue irradiate is lost, then eco-friendly ... Etc.By theway, clouds space made of lot bigger bits, therefore theyscatter clearly shows light relatively evenly -- do themappear white. (But no to also longer irradiate likeinfrared -- which deserve to peer throughclouds).Both procedures make see starsin the daytime very hard. However, if friend happento be in a deep well, v dark walls so that youonly see a tiny bit of sky, and the remainder of youvisual field is dark, you could see part brightstars during the day.... So, carry out you think that theastronauts deserve to see the stars throughout the work fromthe moon?

Answer 5:

The reason we can"t see the stars throughout the dayis due to the fact that when the sun is up, that is therefore muchbrighter 보다 the stars the our eye can"t pickthem out of the sky. You might think the youcould see stars throughout the day if friend looked AWAYfrom the sun, but the sun"s irradiate is spread out outall over the skies by our atmosphere, which is partof the reason why the sky is blue throughout the day(it"s clear at night, right?)Here"s aquestion because that you. Stars, just like the sun, tendto rise in the eastern and collection in the west. Why dothey carry out that?If that"s as well easy, here"s amuch more difficult question. The sunlight rises in the eastand to adjust in the west. But in the summer, the sunrises in the northeast and also sets in the northwest,and in the winter the sun rises in the southeastand sets in the southwest. (In the spring andfall, the sun rises and sets much more or less directlyin the east and west.) exactly how or why does thishappen? (Drawing images may help.)

Answer 6:

In the work the stars space still there, but youcannot check out them since they are so lot fainterthan the sunlight that is scattered by ouratmosphere. If the earth had no atmosphere, thenour daytime sky would be black like at night,except the sunlight would it is in a large spotlight shiningdown at us. In together an unpleasant world we mightsee stars throughout the day. But due to the fact that we have actually anatmosphere, the sun"s light scatters and gives usa beautiful blue glow from all over, not simply fromwhere the sunlight is. In other words, even if youlook far from the sunlight you space still see thesun"s light that has bounced off of part particlein the atmosphere, and that irradiate is much brighterthan the irradiate from the stars.Maybe yourteacher can help you try to uncover out what theparticles are in our setting that scatter thesun"s light and why the scattered irradiate is blue! WHY IS THE sky BLUE?

Answer 7:

It is possible to watch a couple of of the brightest starsduring the day. In fact, over there is one star thatcan periodically be seen throughout the daytime, however cannever be viewed at night! have the right to you guess i beg your pardon one?(Hint -- it"s the closest star.)There areat least two problems with observing stars duringthe job time. First, stars are an extremely faintcompared to the irradiate from the sun (the neareststar). Our eye are adjusted to sunshine duringthe day, and much less sensitive. Not only doesthe iris that the eye contract from the highintensity sunlight, however the retina i do not care muchless perceptible to light as well. A clear sky istransparent to starlight, however the blue shade fromscattered sunshine is bright sufficient to overpowerfeeble stars. The other problem is thatyour eye has an obstacle focusing come infinity whenyou space looking in ~ a featureless blue sky. If youare trying to watch small, pass out things choose starsit is crucial that your eye be focused precisely.However, if friend look in ~ a blue skies there is noreference thing for her eye to focus on and also itis an overwhelming to correctly emphasis on a star.Nevertheless, it is feasible to view somestars in daylight. The stars should be bright, suchas Sirius, Arcturus, Vega, Capella, Rigel, etc.You also need to know precisely where to look, inadvance. Finally, it helps if there is part verydistant thing right alongside the star the you canfocus your vision on. Aldebaran is a great star totry to see due to the fact that it lies near the airplane of theecliptic, and the moon passes an extremely near that onceevery 28 days.

(Often the moon occults Aldebaran,that is, that passes between the Earth and thestar.) If the moon is very near Aldebaran duringthe day, you simply might have the ability to see the if youhave good eyesight.
