The eyes of the Earth.
How does Planet Earth look out at, er, the world [sic.]; I mean, where are its eyes?
That’s right – its telescopes!
Telescopes come in different types and shapes and sizes and uses: there are radio/gamma telescopes, assorted space telescopes, and also optical telescopes – which measure more than a meter in diameter. Of the latter there are just several dozen or maybe just over a hundred in the world. However, there are a lot fewer suitable locations for them; in fact – just three. There’s Hawaii (been), Atacama Desert in northern Chile (haven’t been yet), and the Canary Islands (was there just the other week). All three spots have plenty of clean, dry air and stable weather conditions and are well away from the glare of civilization, aka – ideal astro-climatic conditions.
While on Tenerife last week, after the SAS-2016 conference we decided to go have a look at these large telescopes. We reckoned we might as well since we were there, and hopefully have a chat with the astronomers/astrophysicists, have a feel of the kit, and take the usual slew of snaps (where it’s allowed; and it turned out that it was allowed practically everywhere:).
