Description du produit

On a clear, starry night you can catch a cold, and our
ancestors were sometimes tempted to think that the Moon and the stars
sucked heat from the Earth and made people ill. It was good observation but
dodgy theorizing. Astronomers will now tell you that most of the bright
stars are far hotter than the Sun. Yet when the biggest of them expire in
mighty supernova explosions they spray the Galaxy with atomic bullets, the
cosmic rays. As a result, those exploded stars do indeed chill the world,
by making it cloudier. Like other big discoveries, it seemed crazy at first. Who would think that
the ordinary clouds that decorate the sky take their orders from exploded
stars far off in space? Or that the climate obeys the swarms of atomic
particles that rain down on us from the Milky Way? Many experts scoffed
when the Danish physicist Henrik Svensmark linked those cosmic rays to
clouds and temperatures, but investigations around the world confirm his
theory, altering much of what scientists believed they knew about the
weather, the climate, and the long history of life on the Earth. To unwrap some of Nature's best kept secrets, this book visits unlikely
places, from the Atlantic seafloor to fossil-rich hills in China, and from
the stormy Sun to the spiral arms of the Milky Way.
