It’s an interesting question: how does one consider, view, or photograph what’s under the sun? There’s a lot of room for interpretation. Modifying the theme for the desert sun, I examine the “quality of sunlight” within the Atacama Desert in northern and north-central Chile, and within the Sonoran Desert in southwest United States.
Since 2003, December 11 is International Mountain Day as designated by the United Nations General Assembly. Annually, the Food and Agriculture Organization of the United Nations (FAO) observes the day:
… to create awareness about the importance of mountains to life, to highlight the opportunities and constraints in mountain development and to build alliances that will bring positive change to mountain peoples and environments around the world.
• Mountains cover almost one-quarter (22 percent) of the Earth’s surface.
• Mountains host about 50 percent of the world’s biodiversity hotspots.
• Up to 80 percent of the world’s freshwater supply comes from mountains.
• One in eight people (13 percent) around the world lives in the mountains.
• Mountain tourism accounts for almost 20 percent of the worldwide tourism industry.
The following provides a glimpse to the mountain environments around the world and to the challenging conditions our ancestors would have faced and endured.

The fourth Sunday in September is World Rivers Day. The University of Oxford’s Dictionaries defines ‘river‘ as:
“a large natural stream of water flowing in a channel to the sea, a lake, or another river.”
A river has always been water supply and demand: daily use and consumption; farming and agriculture; and where the waste goes, often back into the same supply. A river has always been about transport: trade and delivery of goods; shuttling people between places; and with people travelling, the exchange of language and culture. Throughout history, the establishment of towns and cities and the subsequent development of rivers have been about a mix of urban and rural elements, and about the relationship and interactions between people and their waterways.
It’s a long road to a latitude of 30 degrees South to stand at an elevation of 9000 feet up on the mountainous spine of South America.
Over a period of 11 years, I visited telescopes in Chile to collect research data, before I moved to Chile to live and work there for 5 years. This is a brief look at the journey an astronomer makes to telescopes in Chile.

The morning creeps gently forward, up and over the desert sky. Sounds? What sounds? What scarce sounds there are, they pierce the silence with soft whistles and drawn-out wails. Alternating light and dark horizontal streamers, known also as “the rays of God,” mark the first light of dawn. Small clumps break loose, as the overnight shroud of valley fog pulls back slowly from view.
The sun climbs higher, the shadows grow shorter, the cotton patch dissolves. It isn’t long until a spectacular sight is revealed. This is what you get from a height of 7500 feet above sea level.
Dry river beds twist and sweep and stretch along canyon floors. Cactus and desert scrub carpets the surrounding hills in faded greens and dusty browns. To the east rise jagged rocky teeth capped with white frosting, fixing the location of the Andes along the Chilean spine.
In this desolate and isolated part of the world, I’ve often wondered about the few brave souls who make this place their home. They’re prospectors, miners, even some farmers, all of whom carry their burden for financial endeavour. People have been digging around in these parts for centuries, whether it’s plant, mineral, or some kind of monetary paydirt.
But there’s another human enterprise with different rewards, a quest that asks questions on a much larger scale.
How do planets take shape?
How do stars form?
How are galaxies assembled?
Is there life elsewhere in the universe?
These issues occupy astronomers from all over the world. Many astronomers go up onto mountains, just like this one, onto the summit of Cerro Tololo, peering into the skies. The telescopes point straight up, reaching out like outstretched hands, wanting more.
