The astro-dweeb has just spent a week observing in Chile. He had a terrible trip back with canceled and delayed flights. During an unscheduled stopover in Miami he had plenty of time to sort through the photos taken with his new camera and to outline a message for me. Click on a photo a couple of times if you want to see the full sized version of anything.
[Edited to add: To reach Las Campanas one drives about 75 miles north of La Serena on the Pacific Coast Road. It quite quickly turns into desert once you leave the outskirts of the city. From the turnoff to the telescopes is a 45 minute drive on a dirt road up the mountain.]
QUOTE: My chariot. Just landed at La Serena Chile after 22 hours of travel. I have now flown more than 2 million miles!
. A military helicopter? I have not previously seen a helicopter at the little La Serena airport.
Dogs like to find any corner for a snooze. There are many seemingly friendly dogs running the streets. The dogs around the La Serena airport know not to go inside the terminal.
CTIO offices in La Serena. CTIO is the headquarters for the American Government southern hemisphere optical observatories. Essentially all large southern hemisphere telescopes are in Chile because the Chilean coastal mountains provide better "seeing" and more clear nights than any place else. The European Southern Observatory (ESO) maintains two observing sites in Chile, including four 8-m telescopes. Two of the three proposed "next generation" telescopes, the European Extremely Large Telescope (ELT) and the international Giant Magellan Telescope (GMT), will be built in Chile.
Condos just beyond the CTIO offices.
The climate in La Serena is very much like San Diego. San Diego is at 32 degrees north, La Serena is at 32 degrees south, both with long stretches of Pacific beaches.

Pisco Sours are the national drink of Chile. This restaurant is right on the beach. I suggest ordering the catch of the day.
The population of La Serena is about 100,000. This supermarket is better than any around where we live in Washington DC. The worst supermarket in La Serena is about on par with the best supermarket in DC.
Still in the supermarket. A $6 bottle of Chilean wine is at least as good as $20 bottle of California wine, maybe better. I am sure this has nothing to do with the fact that the Americans and Europeans put all their large southern hemisphere telescopes in Chile. Carmenere is a lovely plumy varietal that is a specialty of Chile.
Like southern California, foggy mornings in La Serena are very common.
Heading out of La Serena on a bus:
Fog plays by its own rules.
The turn off for the La Silla and Las Campanas Observatories.
The "space pods" are the two 6.5-m Magellan Telescopes at Las Campanas. To the left are a cluster of telescopes ranging from 0.8-m to 2.5-m. At 8,000 feet, Las Campanas is high desert.
Las Campanas is very isolated. It is not on the power grid. Electricity is generated on site. Water is heated with this solar array.
Astronomers at work. Dim your headlights!
The 1-m telescope.
A series of telescopes along a ridge.
The Polish 1.3-m Ogle Telescope. This telescope has made most of the micro-lensing discoveries.
The duPont 2.5-m Telescope. This telescope was completed in 1977 and was the first major telescope on the mountain.
If you love high desert, Las Campanas is the place for you. The tiny white dot in the distance is La Silla, part of the European Southern Observatory.
The cottages in the foreground are for special people, like the observatory director.
More high desert. The peaks in the background are the Andes.
Astronomers hate these beautiful sunsets. The only good cloud is a non-existent cloud.
On the other hand sunrise in the high desert is almost worth staying up all night to see.
This is one of a globe spanning series of telescopes that are used to study solar oscillations. These 5 minute oscillations reveal information about the interior of the Sun such as temperature and pressure that can not be obtained in any other way. These studies have greatly contributed to the solar neutrino problem and the discovery that neutrinos have mass and can change form.
Semi-wild goats, donkeys, and horses roam the mountain. While I did not see any on this trip, I did find remnants of their recent passage.
Another sunset. Beyond the telescopes the coastal mountains and the Pacific are visible.
Sunset facing the Andes. The scenery looks like a fake backdrop for a western movie.
Sunset on the Magellan telescopes:
Fog at the La Serena airport. This fog prevented LAN airlines from landing for 6 hours. As you can see, there is a lot of blue sky. A LAN employee claims the fog is an act of god, it is not their responsibility for delayed flights. I pointed out that it is foggy like this at least 100 days a year, and that LAN could easily install 1980s technology to allow their planes to land. LAN is the only airline at this airport!
This post is about 10 feet from the Lan ticket counter at the La Serena airport. I watched a middle aged woman walk her little Scottish Terrier to this post and then looked on admiringly as he raised his leg and left this little trail. I wish I had the camera at the ready then! A door to the outside was 20 feet away, but that was clearly too much trouble. Small children and babies were crawling all over the floor throughout the day.
Another little "issue" I had with the LAN monopoly at La Serena. There is a strong WiFi radio carrier, but there is no actual internet connection. Another sleeping dog outside the terminal – perhaps the lady would not take her little terrier out to be a snack for this guy.
I did eventually get home with many more photos and scientific data to share with Emjay.
