After a few days in the seaside town of Mejillones, we head south towards the summit of Cerro Paranal in the Atacama Desert. On the way we stock up at a mall in Antofagasta and treat ourselves to a good pizza. Just a few kilometres beyond the city, the landscape shifts into something that\u2019s hard to put into words. Route 28 climbs into the surrounding hills and, after a few kilometres, joins Chile\u2019s main north\u2013south artery, Route 5. A little farther south we turn off onto road B710, which in under an hour brings us to the small airstrip used by staff at the Cerro Paranal observatory. Here we swing west (right) onto Acceso Observatorio Paranal and begin the climb to the observatory. The road threads through a desolate landscape, and the views give full meaning to the word \u201cnothing\u201d.<\/p>\n\n

Our progress stops at the gate to the research area, at roughly 2,400 m a.s.l. The gatekeeper confirms what we basically knew: public visits are offered only once a week and must be booked in advance. We park by the gate and I pull out the drone. I try to fly as close as I can to the summit of Cerro Paranal, still a respectable 2.5 kilometres away and about 230 metres higher, at 2,635 m a.s.l. A strong wind keeps me from reaching the very top, but I still manage a few good shots.<\/p>\n\n

We move on, looking for a good spot to watch the night sky, and end up finding one just beyond the entrance gate. There\u2019s an open view in all directions, plus a clear line of sight to the summit and the observatory on it. We\u2019re here far too early, night still a long way off, so\u2014somewhat paradoxically\u2014we pass the time sunbathing. The tyre tracks make it clear we\u2019re not the only ones who come here. Even so, we end up spending the entire night completely alone. Exactly as we\u2019d hoped.<\/p>\n\n

All around are rolling hills and a desert that feels utterly abandoned. Despite the elevation\u2014around 2,400 m\u2014it\u2019s surprisingly hot, roughly 30 \u00b0C. No water, no trees, no plants, no sign of life. Just dozens upon dozens of kilometres of nothing. The kind of place that reminds you how vast the world is\u2014and how small you are.<\/p>\n\n

Atacama \u2013 gateway to the cosmos<\/h3>\n\n

High elevation, zero light pollution and almost no humidity. These are exactly the conditions that make the area around Cerro Paranal one of the best places on the planet to observe the universe. It\u2019s no coincidence the European Southern Observatory runs some of the world\u2019s most powerful telescopes up here on the summit. Cerro Paranal is known beyond the scientific community, too: the final scenes of the Bond film Quantum of Solace were shot here. Look around and you understand why. The landscape feels raw, otherworldly, cut off from reality.<\/p>\n\n

Across the valley we can see another giant telescope taking shape on nearby, much higher Cerro Armazones (3,046 m). Another sign that Atacama has a big future in astronomy.<\/p>\n\n

The starry show begins<\/h3>\n\n

After a few hours of sunbathing, sunset slowly but surely arrives. We say goodbye to the day and get ready for the big show. For hundreds of kilometres around there are no sources of light. The sky is crystal clear and we sense an exceptional night ahead. Of course we need to change fast. This is the desert, and after sunset the temperature drops fast.<\/p>\n

\n
\"\"<\/figure>\n<\/div>\n

Evening twilight plays in incredible colours\u2014from pale orange through pink and purple to deep blue. It starts subtly. First a few of the brightest objects appear\u2014Jupiter, Mars, later Venus and Saturn. Only then do the first stars come out.<\/p>\n\n

But things change fast. About two hours after sunset the stars are beyond counting. The Milky Way is plain to see, stretching across the sky like a luminous band. Above us it isn\u2019t just a star show but a view into deep space\u2014we can make out distant galaxies with the naked eye. When you realise you\u2019re looking at objects millions of light\u2011years away, it hits you: this isn\u2019t just a pretty night sky. It\u2019s a truly cosmic experience.<\/p>\n\n

Around midnight the observatory gets to work. A powerful laser beam shoots into the sky from the summit of Cerro Paranal. It calibrates the telescopes\u2019 adaptive optics, which cancels out distortion caused by Earth\u2019s atmosphere. To watch this live, in the absolute darkness of the desert, is a powerful\u2014almost chilling\u2014moment. Chilling also because in just a few hours the temperature has dropped from sunbathing\u2011friendly to near freezing.<\/p>\n

\n
\"\"<\/figure>\n<\/div>\n

Time\u2011lapses beautifully reveal Earth\u2019s rotation. The stars draw arcs across the sky and the night takes on a rhythm of its own. All that remains is to add the classic line: And yet it moves!<\/strong><\/p>\n\n

We could watch this show forever, but the falling temperature slowly drives us to seek warmth. First we try the bed of our pickup. It sounds like a great idea\u2014roll out mats, crawl into sleeping bags and watch the night sky lying down until you doze off. Unfortunately the cold seeps through the truck\u2019s metal and into our bags. After about an hour we retreat into the cab.<\/p>\n\n

Make a wish<\/h3>\n\n

When the cold finally creeps into the cab as well, I grab a tripod, camera and headlamp\u2014plus, crucially, hat and gloves\u2014and head up a low hill a few hundred metres from the car. From there I have the whole of Cerro Paranal laid out before me. I set up the tripod, fire up the camera and program a 20\u2011minute time\u2011lapse. I secretly hope the activity will at least warm me a bit.<\/p>\n

\n
\"\"<\/figure>\n<\/div>\n

In the end, something else gets my blood moving. A few minutes into shooting I see a meteor streak from west to east\u2014a long streak across half the sky right over the observatory, ending in a bright flash\u2014and the celestial show is over. My eyes jump to the camera still clicking away. I just hope it caught the moment. Later it turns out it did\u2014and at last one of my photographic dreams comes true: to capture a falling star.<\/p>\n\n

Only in the small hours, just before sunrise, does the Moon rise. Everything around us starts casting shadows and the finer details of the night sky fade\u2014the Moon simply drowns them in its glow. Moments before sunrise we watch the first light reflect off the telescopes atop Cerro Paranal. Tired, chilled to the bone, but full of one-of-a-kind experiences from this mystical place, we wait for the sun, hoping its rays will finally warm us.<\/p>\n\n

Cerro Paranal Observatory<\/h3>\n\n

Construction of the Cerro Paranal observatory began in 1999. More than 30 metres were shaved off the mountaintop to create a level platform for the telescopes. It\u2019s one of the largest astronomical projects of its kind anywhere. If you make it here, a tour of the observatory is absolutely worth it\u2014we sadly didn\u2019t have the time.<\/p>\n\n

Just below the summit is the observatory\u2019s support base: technical buildings, a gym, a heliport, a small airstrip and even a hotel.<\/p>\n\n

Darkness as a commodity<\/h3>\n
\n
\"\"<\/figure>\n<\/div>\n

On the way back to the main road we pass a traffic sign that makes perfect sense here. Darkness is a precious commodity. If you want to drive here at night, you have to drive without headlights. <\/p>\n\n

And that, more than anything, sums up Cerro Paranal: a place where darkness still belongs to nature\u2014and to the stars. One last thing: if you ever come, time your visit for the new moon, when the Moon\u2019s glow won\u2019t spoil the unique experience of the night sky. Good luck!<\/p>\n\n
