Astronomy’s golden age, most astronomers will tell you, is right now. Four centuries after Galileo pointed his telescope skyward, that primordial instrument’s fabulously complicated descendants are giving researchers stunning insights into black holes, the birth of galaxies, even the nature of physics itself. The whole enterprise depends on observatories that cost as much as atom smashers—and need about the same amount of automation.
Providing that automation is a huge challenge. It can also be a blast, if you get to do it for a cutting-edge instrument that happens to be in the gorgeous Canary Islands, as José Losada does. As a senior computer scientist in charge of major systems at the Gran Telescopio Canarias, Losada, 42, writes the code that controls the instrument with the largest light-collecting mirror in the world.
Tenerife, the most populous of the Canary Islands, has the most in the way of people, nightlife, and culture, and it’s on Tenerife where Losada gets to live. But the telescope is on a lofty mountain on the island of La Palma, a half-hour flight away. When IEEE Spectrum visited in June, Losada was subbing for his boss, who was out on sick leave, by supervising 10 people. One or two of them rotate through the observatory on La Palma, but they all live on Tenerife, too.
”This is a good balance,” Losada says. ”Live here, work there—when you need to install something, you go there to do it.” What he installs is software.
His is a laid-back, small-town world, with a tight circle of friends. At a café in Santa Cruz de Tenerife, the bustling little capital, he encounters several friends from past classes in tai chi and contemporary dance, his greatest passion.
”If I could live life over,” Losada sighs, ”I’d be a dancer.” His troupe recently performed in the Audiotorio, a swoopy bird of a building perched on the bay of Santa Cruz. Losada missed that one because he was traveling on telescope business.
We fly to La Palma and find the Gran Telescopio to be worthy of its name. It crouches like an idol in its silvered dome, atop an exhausted volcano, where the air is so dry that it chaps your lips in a few hours. The telescope’s primary, light-collecting mirror, measuring 10.4 meters, is the largest in the world. In its particular sliver of spectrum, the infrared, the Gran peers farther away and thus further back in time than any other such telescope has done, surveying the birth of stars and the tug of black holes—the face of the universe when it was young.
