There’s a really simple reason why the Royal Greenwich Observatory moved their telescopes here. It’s one of the three best places in the world for astronomy. The observatory was founded in 1675 by Charles II of England – hence the “royal” for £520 (£20 over budget!). It was the first purpose-built scientific research facility in Britain. At the time, Greenwich was a great place to build it – away…
The MAGIC telescope has the biggest telescope mirrors in the world. I’ve always wanted to get up the green tower to prime focus, where the light is focused onto the camera. I finally got up there in July. Even better, my friend Carolin Liefke (from the Max Plank Institute) had a camera with a fisheye lens and the skill to make good use of it. You can read more…
Tuesday night is the best meteor shower of the year, the Perseids. Of course it should be visible all over the planet, but La Palma’s astronomical viewpoints will probably be a particularly good place to see shooting stars. Unfortunately the full moon will spoil the show quite a bit. Cielos La Palma will be in La Polvacera basketball court from 9 pm – midnight with telescopes. Toño will also…
Two of the fourteen telescopes at the Roque de los Muchachos observatory are solar telescopes — highly specialised to observe our own sun. This is the Swedish Solar Telescope, which was the first telescope built on the Roque. It’s currently the best solar telescope in the world since they added the new adaptive optics in 2005. (Adaptive optics compensate for air turbulence.) It can resolve details of the sun’s surface…
You see a lot of flags on La Palma. Most English visitors will recognise the flags of Spain and the European Union. But the Canary Islands are an autonomous region within Spain, and they have their own flag too. You see it a lot, especially around May 30th, which is Canary Day. And then each island has its own flag. Here’s the flag of La Palma: And as if…
Today is Canary Day. Like the national day in most places, it’s an excuse for lots of patriotism. So here’s a picture of some traditional Canarian food – wrinkly potatoes. As you can see, they’re small potatoes, cooked in their skins. Actually they’re boiled in very salty water – you can use sea water – for at least 20 minutes, then allowed to dry with the remaining heat. They…
