The Antarctic island of South Georgia is home to a million King penguins, plus countless fur seals, gigantic elephant seals, staggering numbers of seabirds such as albatrosses, amidst a backdrop of towering mountains with massive glaciers spilling off them.

Nothing can prepare you for the incomprehensible size of the penguin rookeries here, densely packed as far as the eye can see (all those white dots on the hills behind are penguins). Nor for the size of bull elephant seals weighing up to 8,000 pounds, especially when they rise up and crash their chests against each other in mating challenges emitting deafening bellows. Nor being surrounded by a thousand fur seals unafraid of you. The density of wildlife combined with the magnificent beauty of the island is completely overwhelming.

Here also is the abandoned whaling station of Grytviken where the heroic explorer Ernest Shackleton is buried. You can only get here by expedition cruise ship. South Georgia is one of the great experiences on our planet. (Glimpses of Our Breathtaking World #96 photo ©Jack Wheeler)

You’re looking at something historically and scientifically astonishing. It is what remains of an astronomical observatory built 600 years ago – in 1420 – by a Sultan in Central Asia who loved science and mathematics more than war and conquest.

It was in Samarkand, the most fabled oasis of the Silk Road, that Sultan Ulugh Beg built his circular observatory, three stories high of white marble. All that’s left today is part of the underground sextant that you see in the photo.

For the full story of what he achieved, with many more photos, click on The Sultan Astronomer in TTP I wrote in 2020.

This Glimpse is to whet your appetite to learn about this amazing Sultan and his scientific achievements.

It’s also to whet your appetite for joining your fellow TTPers on our Heart of Central Asia expedition this September. The story of The Sultan Astronomer is but one example of what awaits you in exploring Central Asia, an enrichment of your life beyond description.

April 1990. When our oldest son Brandon was six years old, I took him with me to the North Pole. It was my 14th expedition there, and as always, we stopped to visit friends at Canada’s northernmost community, the Inuit hunting village of Grise Fiord on Ellesmere Island. Brandon thought it would be cool to sleep in an igloo, which the Inuit do only when they’re hunting seals or walrus far out on the ice.

So the villagers happily complied, showing him how they built one, carving out blocks of wind-blown snow, shaping and placing them in an inward-sloped spiral with one block on top, and packing snow as mortar between the blocks. When it was bedtime – still daylight with 24-hour sunshine by April – they lined the inside with caribou skins, which shed like crazy with hairs everywhere but sure are warm. Snuggled into our arctic down sleeping bags, we slept like stones.

It was an experience both of us will never forget. Never pass up an opportunity to have an adventure with your kids they’ll always remember. (Glimpses of Our Breathtaking World #50 Photo ©Jack Wheeler)

Aït Benhaddou is a thousand year-old kasbah or fortified village on the ancient trade route from the Sahara to Marrakech in Morocco. It’s constructed entirely of rammed earth, adobe, and wood.

Remember the famous scene in Gladiator where Maximus shouts “Are you not entertained?!” to the bloodthirsty crowd? It was filmed here, as were scenes in many other movies such as “The Jewel of the Nile,” and “The Mummy,” or the series ”The Game of Thrones.”

Yet this is no location set – people live here, scores of families, as they have for a millennium. You’re welcome to come here to see how they live for real – as here Hollywood is far, far away. (Glimpses of Our Breathtaking World #181 photo ©Jack Wheeler)
