地球、宇宙"From this faraway viewpoint, Earth may appear insignificant. But for us, it's everything. That tiny dot, that’s our home, that’s who we are."

Carl Sagan once shared his thoughts on an iconic image of Earth captured from a distant perspective. He said: "From this faraway viewpoint, Earth may appear insignificant. But for us, it's everything. That tiny dot, that’s our home, that’s who we are."
