Images from this year's dazzling light festival
Shark Bay, Australia
Of all the natural wonders on this list, Shark Bay is perhaps the most significant. Though it’s hardly extraordinary to look at or even particularly well-known outside the country, this bay in north-western Australia contains strange little hillocks formed by some of the earliest life-forms on earth – marine stromatolites. To these 3,500-million-year-old organisms all life as we know it owes its existence, on account of the way they absorb carbon dioxide and emit oxygen.
