Will the night sky on our planet eventually become brighter and brighter because of the lights of many stars eventually lighting up the sky?? And if we took the suns light away from the day would we see different constellations in our sky?

  1. No. The number of stars being born and the number of stars dying is approximately equal, so there is no overall change. Also, even the closest extrasolar star, the Alpha Centauri system, is a mere dot of light.

    Taking the sunlight away will not show other constellations. During the day, the Sun blocks vision of them. However, 6 months later, they will be visible because the Earth will have moved to the other side of its orbit.


  2. Close to the equator, one can see the band of the Milky Way and it is so bright, you can read large type.  Kind of like the way it looks when snow bounces light around at night.  It depends on how much light pollution there is.

    In some really dark areas of the USA like the Smoky Mountains, it's so dark, the stars come out so much they crowd out the more familiar constellations like the Big Dipper.

  3. No, the light from distant stars doesn't get here and then hang around.  It's absorbed - by your eyes (that's how you see it) or the Earth (makes little difference to the Earth, they are so dim).  Our galaxy isn't producing nearly enough new stars to light up the sky at night more than it is now, and you're really not seeing anything outside our galaxy (except Andromeda).  

    The Sun, during the summer, is passing through the winter constellations.  If you took it away, you'd see the winter constellations during the day and the summer ones at night.

  4. No for a couple of reasons. One is that stars are born and die out at about the same rate. And second, even the closest star shows up as a dot in the sky.

    If anything we are seeing less stars because of the growing amount of lightpolution with our advancing civilization. You are supposed to see about 1000 stars in the night sky without a telescope, but with all the light polution your lucky to see 100.
