Earth: Our Unique Cosmic Home

Earth is literally racing through space at 67,000 miles per hour while spinning like a giant top,

and you can't even feel it. This blue marble we call home sits in what scientists

call the Goldilocks zone, not too hot, not too cold, just perfect for

liquid water. What makes Earth truly unique is its protective atmosphere that burns up thousands

of meteors daily before they reach us. The planet is 71% water,

yet most of it remains unexplored. We've mapped more of Mars surface than our own ocean

floors. Earth hosts over 8.7 million species, from microscopic bacteria to massive

blue whales. Every breath you take contains oxygen produced by plants and ocean algae
