If there is one thing I would like to see before I die it would be an Aurora!

This is a NASA video of the Aurora Brealis over the Great Lakes and Canada. Teken recently:

Just for balance to the misinformation published with the second of the images (that of the McClure Strait which the blurb says has been fully open since 2007), here is an up-to-date image of the state of Arctic sea ice from the National Snow and Ice Data Center.

Methinks they missed out an important phrase from the blurb, one saying that the McClure Strait "has been open for a short period at the end of summer each year since 2007" before it freezes up again for the winter. Just for balance, it's important to remember that it had been open in some summers before that too.

Whole truth and nothing but the truth, please!

Fantastic.
Interesting to read how these images were made.

Ten years of gorgeous images of Earth from space

That looks like a series of the clouds called "Morning Glory" that were shown on QI the other night. In that case it was just one rope of cloud which stretched for miles and was a regular tourist attraction in a little town at the back of beyond. Must be a result of the landscape and the wind patterns.

Amazing! I must be more mundane because my first impression was of tyre tracks, then I realised that this matches the description of cloud 'streets'.

Arran sweater I reckon

Butternut Tue 31-Jan-12 08:14:51

Goodness, that's lovely.

Think it also looks like a magnification of a knitting pattern

Cloud "streets", off Alaska:

There's no light pollution where I live, and the star-lit night skies are wonderful.

I think the man is French!

bagitha Fri 27-Jan-12 15:20:34

Milky Way. I love the stars and the tree silhouettes. Not so sure about the guy peeing in the foreground!

I've a feeling they mean tallest rather than biggest.

Annobel Fri 27-Jan-12 13:10:23

Yes, they are lovely trees, but if they are looking at the world's biggest trees, I wonder why the ancient kauri tree known as Tane Mahuta, king of the forest, in North Island, NZ, wasn't included. This tree has reached the age of 1500 years, is more than 51 metres high and has a girth of 13.7 metres. Kauris have been cut down in the past for building Maori canoes and homes; and by European newcomers for the timber trade. Now the emphasis is on conservation.

Love trees!

bagitha Fri 27-Jan-12 12:48:40
