    Any idea how large the image of Google Earth is ?? The one which covers entire earth(down to maximum zoom level). 😀 . I mean yeah that is superimposition of many images but still , it's size in terms of megapixels must be amazing.

    It is a composition of many millions of small images. As a whole, it would be a million miles long...
    To be exact, it is 510,072,000 km[sup]2[/sup]. 😉

    Amazing view. You can really see the Raman effect as the thin blue band of atmosphere. That is all the extent of the so called deep blue sky.

    NO, not the clouds. If you look at the edge of the earth the thin blue band (about 2 mm thick in the above image) is the actual atmosphere surrounding the earth. I went to your link to see the full image. It is clearer in that.

    Wow, I never cared to read about the Raman effect. Could you explain it very briefly, with the context of the image?

    It is Sir C.VRaman that gave the ecorrect explanation for why the sky is blue.

    I had met Raman a few times. I very much wanted to do physics and work with him. It was not to be. However, I did get to work under Prof Ramaseshan, Raman's student and nephew, for many years. So in a sense I am Raman's grand student!
