The reason of this is that near the horizon we look through a very great thickness of the lower atmosphere, which is full of the larger dust particles reflecting white light, and this diluter the pure blue of the higher atmosphere seen beyond, And in the vicinity of the sun a good deal of the blue light is reflected back into space by the finer dust, thus giving a yellowish tinge to that which reaches us reflected chiefly from the coarse dust of the lower atmosphere.

Dis- Fly away lonely souls into the endless sky so far away When you're all alone Feeling down and lonely Tell me what you see deep inside your soul You only know who you are So don't be afraid Just open your heart to me You will spread your wings like an eagle Learning how to fly in the sky Just like the sun rises after the rain you'll shine in the air Take off your mask and be true to your heart trust yourself and fly away Into the light of joy and truth Where there's a grief there will always be a hope For a place where we can be who we wanna be Your tears may fade away But always keep the faith and live tomorrow Break through the night away into a brand new day Life's just begun Yeah, feelin' the melody of eternity It has the power to set us free Travlin' through the galaxy with only space around Follow the suns peaceful sound It's time for us to end this illusion Fightin' ourselves will only cause confusion Shinin' light is the key of life Let's all get together and make this better I don't know how but there has got to be a way There are times when I Wish I could just disapear Far from this place of pain and hurt If only I could be gone There's something in your eyes Pulls me back from running away Oh, yes it's hard sometimes But now I'm strong enough to tell the sadness goodbye Just like the moon fills the night with the stars I'll dance in the air Seek in the darkness there's nothing to fear I will stand and fly away Into the night I'll find the truth The pain never ends but there's always be a hope To be free eternally in this galaxy To live another day the sun will show the way and I will follow Break through the night away into a brand new day My journey goes on Into the light of joy and truth Where there's a grief there will always be a hope For a place where we can be who we want to be Your tears may fade away But always keep the faith and live tomorrow Break through the night away into a brand new day Your journey's begun
