Northern extremes. Camouflage is a key survival strategy for many animals. But what do you do if your habitat changes dramatically with the seasons? From high mountain habitats to the Arctic north, animals have developed a seasonal wardrobe to stay under cover — and stay alive.

Our new story of the Universe is set within an ultimate mystery. It is a myth like all the preceding ones of whatever culture or religion. This one is woven from wider strands of experience and imagination, fed by electronic circuitries, seen through electronic eyes, shepherded by a common scientific method. This ultimate personal history traces our individual existence beyond our families, beyond our species, beyond life, beyond the earliest galaxies, and finally beyond the primordial fireball to the time when there was not time, the place where there was no space, and there was only mystery.
