Aurora boreal

moussette_aur16jul1_full.jpg (153 KB)

Explanation: While enjoying the spaceweather on a gorgeous summer evening in mid-July, astronomer Philippe Moussette captured this colorful fish-eye lens view looking north from the Observatoire Mont Cosmos, Quebec, Canada, planet Earth. In the foreground, lights along the northern horizon give an orange cast to the low clouds. But far above the clouds, at altitudes of 100 kilometers or more, are alluring green and purple hues of the aurora borealis or northern lights, a glow powered by energetic particles at the edge of space. In the background are familiar stars of the northern sky. In particular, that famous celestial kitchen utensil, the Big Dipper (left), and the W-shaped constellation Cassiopeia (right) are easy to spot. Then, just follow the pointer stars of the Big Dipper to Polaris, perhaps the most famous northern light of all.
Eu nunca ví, mas, além da física, deve ser bonito! Mas a beleza estética não exclui a beleza da física!!!

    What makes you think I understand Portuguese? Anyway, yes, it doesn’t matter if it’s a perfectly logical and natural occurrence or if it’s a piece of art that someone created in his basement because he had too much free time. I enjoy colour, and colour in unusual places makes me all giddy.

    Stunning. I would love to see this in person.


    i’ve only seen the yellow and variety, apart from the “normal” colour.!img4866570.jpg
    also crazy about some of the patterns, like this “path”.

    the purple looks so close in the pic . awsum!


    I once knew a chick with nipples that were so big, we called them the Areola Borealis.


    Were they also green and purple and stuff?
    Also: send pix!


    It’s just, like, physics, man


    i lived in Alaska for 20 years- it never got old. i’ve seen several weak displays down here in the Washington area.


    Hubby has been to Alaska several times and has some pics somewhere. We’ve had green borealis as far south as West Virginia, but no other colors.
