Columnas luminosas que montan al cielo de Ontario

Début janvier, Timothy Joseph Elzinga a assisté à un spectacle exceptionnel. Vers 01h30 du matin, ce Canadien a aperçu des colonnes lumineuses multicolores illuminer le ciel de l’Ontario, rapporte le site Mashable.

Estas columnas de luz son visibles cuando  finos  cristales de hielo finos están a bajo nivel en el aire. Cuando el cielo está despejado ", los cristales de hielo  pueden alinearse en un plano horizontal y formaruna pila vertical. Se comportan como espejos  que reflejan la luz horizontales y masivamente ", dice el sitio especializado en la ciencia.

Lo cierto es que es hermoso y hace pensar a los extraterrestres.

Extraordinary images captured in Canada have shown rare light pillars beaming up to the sky above the houses after a combination of sunshine and snow.
The pillars are caused when temperatures plummet so low that water molecules in the air freeze but remain stationary in vertical shafts.
They then reflect artificial light coming from street lights, neon signs and even homes to create the bright colours.
And unlike the natural northern lights, light pillars can be partly man-made and there are no magnetic fields involved.
One person to spot the rare phenomenon over the Canadian sky was photographer Darlene Tanner in Blackflads in Alberta.
She said: 'I spotted loads of amazing light pillars whilst out in Blackfalds and managed to get some good photos.
'The light pillars were very defined, it was -27 with wind chill.'
While another person to spot the light pillars was Timothy Elzinga in Ontario, where temperatures had plunged to -18C.
Mr Elzinga had got out of bed when his son started crying - and he noticed the incredible light show outside.
He said: 'It looked almost supernatural - like some kind of intergalactic wars, with beams shooting down from the sky.
'It was very bright in person, like nothing I've even seen before. It seems like nobody has really seen this kind of thing, either.
'There were beams of light being shot out of the atmosphere down to the ground, all different colours shimmering and changing.
'It's about the one time I'll be glad to get waked up at 1.30am by my son crying. If not for that I would have missed it.'
'It was pretty amazing. I just happened to be in the right place at the right time.
'It was so cold that night that it froze the moisture in the air, creating crystals so small that are perfect for prisms of light to shoot out from.'
