Aurora borealis

A couple of weeks ago my very good friend from Thessaloniki, Agni, returned from a trip to Finland and sent me these pictures of the Northen Lights, or to give it its correct scientific name, the Aurora Borealis. The Aurora occurs when streams of charged particles from the sun are driven out into space by the solar wind. They are largely deflected by the earths magnetic field but at the poles where the magnetic field is at it’s weakest they can enter the atmosphere and react with different gases, and different gases produce different colours. The most common colour is yellowy green which is generated by oxygen at a height of around 60 miles.

Despite being half Danish and spending nearly all my summer holidays, and some winter holidays, in Scandinavia, I’ve still never seen the Aurora, so I think these pictures are absolutely stunning. And it must have been totally jaw-dropping to see it for real so I’m now even more on a mission to go and see them for myself!

Aurora borealis‘ means ‘dawn of the North’ and is named after the Roman goddess of the dawn, Aurora, and the corresponding Aurora in the Southern Hemisphere is called the ‘Aurora australis‘ or ‘dawn of the South’.

I don’t normally post other peoples pictures here but these are so special they have to be shared, so I’m really grateful to Agni for letting me post them. They were taken with a Nikon D3200 on a tripod with a 10s exposure time. And they’re so cool!
