• Stargazing tourists flock to Africa’s darkest region

  Not many tourist spots boast of being dark and difficult to get to, but the Namib Desert is one of a number of remote “Dark Sky Reserves” drawing in stargazers for a celestial safari.

  In the cool night air, an urbane Austrian tourist climbs rocky steps behind a chic hotel lodge and peers into a matte-black metal cylinder containing a spine of mirrors and lenses that reveal the universe.

  “My mum wanted to set him on fire yesterday when he said: ‘We are looking 10 million years in the past,’” he joked, pointing at the resident astronomer.

  Not everyone is ready to face the scale of the universe laid out so starkly by powerful magnification and the crisp desert sky.

  However, across the starkly beautiful Namib, hotels and lodges are betting that the stars will lead to more business, rather than a spike in Galileo-esque witch hunts.

  Many lodges have purchased research-grade or “prosumer” telescopes and hired live-in astronomers as they try to lure tourists who want to gaze deeper into space and time.

  According to consultancy Euromonitor, so-called “astro-tourism” vacations are growing in line with increased urbanization, with Africa in particular taking off.

  “Most people come here for the other activities: visiting the dunes or the nature reserve where you see all the wildlife. This is kind of a bonus,” said Misha Vickas, formerly a guide at a public observatory in Sydney, but now resident at the And Beyond Sossusvlei Desert Lodge. “Most people have never looked through a telescope and a lot of them have just never looked up.”

  Vickas operates a “go-to” telescope, a device which, once calibrated, pivots on demand to any star or planet with little more than a mechanical hum and whir.

  Not that a telescope is really needed in the Namib.

  Across as much as 50 percent of the Earth, the starry firmament is obscured by an orange glow of anthropogenic light pollution.

  During the day, the Namib’s sea of copper red and ecru yellow dunes and mountains glow blindingly, befitting the world’s oldest desert.

  However, in the inky night sky, the Milky Way seems much closer than Windhoek, a half-day’s drive away across dirt track and sun-rippled single-lane carriageway.

  The red glow of Mars, Magellanic clouds — dwarf galaxies outside our own — and assorted gaseous nebulae are all visible to the naked eye.

  “The sky is particularly good to look at here, because the Milky Way — which is the main part of our galaxy — is usually very high overhead,” meaning light refraction is at a minimum, Vickas said. “There is a lot to look at.”

  In 2012, a sliver of the central Namib the size of Mauritius — the NamibRand — was named Africa’s first “Dark Sky Reserve,” in recognition of the sky’s special allure here.

  A handful of similar sites exist elsewhere, including Aoraki Mackenzie on New Zealand’s South Island and the Iveragh Peninsula on Ireland’s southwest coast.

  Hawaii and Chile are also gaining renown as astro-tourism hot spots.

  “The darkest places are almost inevitably distant from populated places,” said John Barentine of the Arizona-based International Dark-Sky Association, which awards the designation.

  “The glow of cities can often be seen several hundred kilometers away, under good conditions,” he added.

  To rank sky quality, scientists use measurements like the Bortle scale.

  An inner city is level nine, meaning you can see very little. Bright constellations like Orion might be faint or even invisible.

  At the other end of the scale — in a first-class sky like the Namib — Venus and Jupiter shine bright, a white spray of zodiacal light smears the sky.

  Like parts of Chile, the Namib’s good weather and ultra-dry atmosphere make for clear nights and particularly transparent air all the way to the horizon.

  “A visitor to NamibRand has a statistically high probability of experiencing that exceptionally dark sky on any given night,” Barentine said.

  Namibia has just over 2 million people spread over an area about the size of Pakistan or Nigeria, making it one of the most sparsely populated nations in the world.

  “NamibRand is located in one of the darkest accessible places that remain on Earth,” Barentine said. “It is as close as you get to the way the world was long ago, before the invention and proliferation of artificial lights.”

  That might be the only thing this remote region is close to — thankfully for stargazing tourists.
