SUN 3 Traveler beware: Five-billion-year-old nuclear fusion reactor in operation! Think of the Sun’s heat on your upturned face on a cloudless summer day; think how dangerous it is to gaze at the Sun directly. From 150 million kilometers away, we recognize its power. What would we feel on its seething, self-luminous surface, or immersed in its heart of nuclear fire? And yet, our Sun is just an ordinary star, one of 400 billion in the Milky Way Galaxy, which is one of billions, perhaps hundreds of billions, of galaxies in the Universe. Someday, five or six billion years from now, when all the hydrogen fuel in its interior has been converted into helium, the Sun will begin to evolve into a Red Giant. Ruddy and bloated, it will envelop and devour the planets Mercury and Venus—and probably the Earth as well. The inner Solar System will then reside within the Sun.
