Mars, the red planet, is ingrained in our culture, from David Bowie's extra-terrestrial spiders to Captain Scarlet to War of the Worlds. It has inspired hundreds of authors, scientists and science-fiction writers - but why? What is it about this particular planet that makes it so intriguing? Ancient mythologies defined Mars as a violent harbinger of war, star-gazers puzzled over its peculiar motion, and astrologers defined human personalities by its position and bizarre dance through the sky.

Naturwissenschaft leicht erzählt. Die Schwerkraft kann man mit einer Pfannkuchentorte erklären und die Relativitätstheorie mit dem Bauch einer dicken Katze. Klingt irre? Ist es auch! Vor allem, weil es funktioniert. Mit Begeisterung erzählt Johan Olsen vom Urknall über die Entstehung des Lebens bis zum Menschen. Er erklärt Atome, Relativitätstheorie, Moleküle und Proteine, also was man alles braucht um eine Welt zu erschaffen mittels humorvoller Veranschaulichungen - und warum der Mensch vielleicht doch nicht die Krone der Schöpfung ist.

New York’s Battery Park is under water. The beaches of the Jersey Shore are reduced to thin strips of sand. Huge portions of California have been reduced to burned hellscapes due to relentless fires and mudslides.

In the mid-1990s, astronomers made history when they detected three planets orbiting stars in the Milky Way. The planets were nothing like Earth, however: They were giant gas balls like Jupiter or Saturn. More than 500 planets have been found since then, yet none of them could support life. Now, armed with more powerful technology, planet hunters are racing to find a true twin of Earth. Science writer Michael Lemonick has unique access to these exoplaneteers, as they call themselves, and Mirror Earth unveils their passionate quest.
