Dust, comprised of particles from near and far, including the depths of space, turns out to be incredibly varied in its composition:

Dust is hugely diverse. The biggest particles are more than 2 millimetres across; the smallest, less than 0.1 micrometres. Excitingly, some have cosmic origins: around 200,000 tonnes of extraterrestrial material enters the atmosphere each year. This is dwarfed by the 4 billion tonnes from Earth itself, though, more than 90 per cent of which comes from natural sources such as soils, volcanoes, deserts, pollen and sea salt. The human contribution is far smaller, but we are responsible for some of the nastier little particles, including those from car exhausts, industrial emissions and fertilisers.

Yes, last Wednesday in Sydney was certainly a red letter day, but for all the wrong reasons. It was an eerie feeling – to say the least – looking out the window that morning to see an orange coloured sky.

And if you’re looking for some photo galleries of the freak weather event, then check out The Big Picture, Sydney Morning Herald (multimedia format), and The Red Sydney Project – Dust Storm Days at Flickr.

Dirty Car Art by Scott Wade.

I’m always interested in the materials and mediums artists use in their work, but this is the first time I’ve seen someone work with “dust” and “car rear windows”.

Some of the images are truly stunning.
