Our planet Earth. This is the only spot in our cosmos that harbours life, as we know it. The atmosphere and environment here has enabled life to thrive. Complex and intelligent life like us, humans evolved here. Our intelligence has now enabled us to realise that Earth is very unique and therefore we must protect it. Let us do all that we can to understand our Earth and protect the glory of our 'Blue Marble'. Here, you will find scientific stories of the Earth, its changing environment and behaviour in the cosmos.
