“From the moment Earth first coalesced out of cosmic dust 4.5 billion years ago, one star has been our unbroken companion: the Sun. It has bathed our world in warmth, painted skies with dawns and sunsets, and sustained every breath we take. Every tree, every ocean wave, every heartbeat is a gift of solar energy streaming across 150 million kilometers of space to nourish life.”
