Aurora Stepping Stones
Deni Cupit
Tasmania is fortunately one of the best placed locations on Earth to view the famed Southern Lights. Better known as the Aurora Australis, it is a natural phenomenon in which solar particles reach Earth’s atmosphere, colliding with nitrogen and oxygen atoms. The collisions of these particles with oxygen produce red or green light; whereas with nitrogen they produce green or purple light. The electrons are stripped from the particles, leaving ions in excited states, which then emit radiation in various wavelengths. In short, this is a G-rated strip show that is fun for the whole family.

BEAKER STREET SCIENCE PHOTOGRAPHY PRIZE
This photograph was a finalist in Beaker Street’s annual Science Photography Prize. This highly-respected prize invites all Tasmanians to showcase the wonders of our extraordinary part of the world — which is teeming with science and scientists. Finalist images are displayed at the Tasmanian Museum and Art Gallery during Beaker Street Festival each August, with great prizes on offer for Judges’ and People’s Choice winners.
The Beaker Street Science Photography Prize would not be possible without the support of Full Gamut, Tasmania’s premier fine art printers and long-time sponsor of this competition. Many thanks also go to Pennicott Wilderness Journeys, which donates a generous prize for the People’s Choice winner.
