There was a solar eclipse in March, and all I saw was cloud. I was prepared for this, of course, what with living in the UK these days. But all was not lost! I still got a photograph (indirectly) of the whole thing in the form of this time-slice, which shows a period of about three hours from left to right. I wrote a Python script to do all the legwork for me, which I’ve put on GitHub should anyone want it. Continue reading
Ok, so Venus isn’t an extrasolar planet (exoplanet), but I thought this would be a cool thing to try. A while ago I put together a time-lapse movie of the 2012 Transit of Venus. More recently, during a public talk on exoplanets, I saw a video someone had made to demonstrate the transit method used to detect planets around other stars. The video looked a bit like my time-lapse, except that it was a simulation. I thought, “why not try to get a real light curve from my transit footage?” Continue reading
I have compiled the following time-lapse video, inspired by Ken Murphy’s “A History of the Sky”. Ken’s time-lapse is actually a mosaic of 360 smaller individual movies, each showing the San Francisco sky throughout a single day. The result is a brilliant and unique visualisation of an entire year of weather in just a few minutes.
I present Her Majesty’s equivalent, “A History of the British Sky”, recorded from the top of a building near the Welsh border. I’m sure you’ll agree that the time taken to process over 3 million individual photographs is repaid ten times over in this video. Such a wealth of information in one view; it’s a feast for the eyes. You can see the change in the length of the British day, for example. And you can clearly pick out the season of summer.
EDIT: Positive responses to A History of the British Sky:
“I always knew you could get different shades of grey, but never so many different types of grey.” -Gordon
“I can see summer! It’s up in the top-right!” -Tina
“This particular year looks drier than most.” -Margaret
Seriously though, I’d like to thank Ken for his original and actually genuine creation, which, unlike my version, took an awful lot of commitment and skill to pull off. Such a cool idea!
I’m pretty much fuelled by coffee, but last year I developed an extra habit: whenever I was served a fancy frothy coffee at a café (you know.. cappuccino and the like), I would take a photo with my iPhone. And here they are in date order!
