Weekend Unthreaded

……..

More beach holidays. Apologies to Northern Hemisphere readers. We’ve had three beach holidays in two weeks with various friends and relatives. January in Australia is tough. 😉

I love the colors of the Western Australian coast. The sky really is that intense blue, and the water is that clear. We fed stingrays at Hamelin Bay at sunset too. This is a seven year old boy hand-feeding a tame eagle ray which must have weighed twice as much as him. That one had no tail, but others did. Remarkable. Click to enlarge shots.

We had a an excellent few days holiday this week in the South West of Australia. What still surprises me is how these giant trees seem to sneak up on you. One minute you’re driving through normal forest and the trees don’t seem to “get big” but you suddenly notice the scale of everything has changed. Like the car and road shrank instead.

Karri trees are some of the tallest trees in the world. See the trunk girth of a medium specimen. Try to imagine this tree in your yard.

Karri Forest, Caves Road, Western Australia

They must be the most beautiful.

I’m sure some people must be tired of discussing the solar model 😉

Unthreaded Lewandowsky weekend

What can I say. Not another “downfall” video, oh yes. Oh Yes! But for those who know the background on the Recursive Fury retraction, the irony is delicious. Enjoy. Right to the end.

Yesterday I said I had to learn German. Today it’s probably better that I haven’t.

Read on for clues if you are not familiar with the saga.

Each year the winter whitewater carves out a tiny bit more rock, and each summer we see the ripples in the granite.

Is a rock on the way? (and a Weekend Unthreaded)

50,000 years ago a bit of wayward rock about 50m across met Earth and left this 1200m wide crater in Arizona.

Ponder the momentum of 50m bit of rock that left a hole over a kilometer wide and 200m deep.

If one was coming. Would we know?

Thanks to NASA and The Earth Observatory

UPDATE: JoeV in comments adds an interesting link to Tracking space junk at Satview.org. An old satellite is coming in right now. It’s over Alaska (moving fast) at 153km high and falling quickly. Cosmos 1220, a Soviet era military surveillance satellite. Eddie adds a different link which suggests Cosmos is expected to crash into the Pacific in hours. Amazing what you can find out on the Internet.

I took this flying from Denpasar to Perth. Glorious ancient landscape in the dry season north-west WA. Click for a larger broader image.

UPDATE: thanks to help from Steve R W, I think I’ve found the location. It appears to be part of a long ridge in The Barlee Range, just north of the Frederick River in the Pilbara area of Western Australia. It is so remote, Google Earth tells me “you can’t get here from where you are”.
