The Pacific Ocean, looking north with a bit of east from Manly Beach, Sydney. Beyond the horizon is Vanuatu, from where I have just returned.
Since I have made even more museum-related posts, I have revised my earlier tag maps to give the clickable mosaic below. This tag map links to many (though not all) of my posts concerning museums (large and small) around the world. See the mouseover text, or click to jump to the relevant post:
The centre four rectangular photographs (and all six circular ones) here are mine; the others are public domain.

I’m back in Australia, after a month in the tropics. For the next few days, I will be catching up on solar car news, and updating my World Solar Challenge team list.
I will be offline for a few weeks. A variety of science-related posts are queued during my absence, but solar-race coverage will be on hold until I return (my WSC team list is up to date as at 23 June). See you all later!
The Christmas fresco above, by Giotto, shows the Star of Bethlehem as a comet (top centre). It is likely that this fresco depicts Halley’s Comet, which Giotto saw in 1301, about two years before he began the series of frescos of which this is part. This work by Giotto was celebrated in the name of the Giotto spacecraft, which observed the comet in 1986.
Let me take this opportunity to wish all my readers a very happy Christmas (and apologies for duplicating a previous post).
