And the blue sky on that last one that gives the game away. Yes, it’s Earth, not Mars. It’s actually the Teneguia volcano, on the southern tip of La Palma. The red colouring comes from iron in the rocks. The reason why there’s no visible vegetation is that the volcano last erupted in 1971, just 37 years ago. Some of these little holes in the ground (just big enough to…
Teneguia
Hurrah! After seventeen years on the island, I finally got to the summit of the volcano Teneguia. It’s only 400 m above sea-level, and I didn’t walk all that far. But I’m horribly unfit and it’s a rough path. And besides, I have a horrible tendency to leave everything to some mythical day in the future when I won’t be so busy. So I’m proud of myself for getting up…
The MAGIC telescope
This is the MAGIC telescope (Major Atmospheric Gamma-ray Imaging Cherenkov Telescope). It’s perhaps the most exotic telescope at the observatory at the Roque de los Muchachos. It’s not an optical telescope. Instead of observing visible light, it’s looking for gamma rays. Visible light is made up of different wavelengths, which give the different colours from red to violet. Wavelengths which are just a bit too short to see form ultra-violet…
Los Sauces Sardine Postponed
Los Sauces always hold their Sardine’s Funeral a week or two after Santa Cruz. It was supposed to happen on Saturday, but we had an orange weather alert. The rain poured and the wind gusted, and it was obvious that nobody was going out if they could help it. In one way it’s a good thing – the reservoirs were very low after such a dry winter. It’s finally stopped…
A Carnivorous Shopping Trolley
It’s been pouring with rain for days. Eventually I had to go out and get shopping regardless. I went to the supermarket at San Antonio, and I had to park on the steep slope beside the building. It wasn’t raining when I went in, but as I came out, it was pouring with big gusts of wind . I didn’t want to sit in the car and wait, because I…
Giant Lizards
Yesterday I clean forgot that in December last year they found out that the giant Canarian lizard, Gallotia auaritae, isn’t extinct after all. José Antonio Mateo, a reptile expert, only found the one, but he believes there must be a colony within a kilometre of the one he found. In this case, “giant” means 30 cm (one foot) long. Extinct specimens are larger. Twenty-five years ago, they thought Gallotia…
