APOD: Mars over Duddo Stone Circle (2021 Mar 23)

Post by APOD Robot » Tue Mar 23, 2021 4:05 am

Image Mars over Duddo Stone Circle

Explanation: Why are these large stones here? One the more famous stone circles is the Duddo Five Stones of Northumberland, England. Set in the open near the top of a modest incline, a short hike across empty fields will bring you to unusual human -sized stones that are unlike anything surrounding them. The grooved, pitted, and deeply weathered surfaces of the soft sandstones are consistent with being placed about 4000 years ago -- but placed for reasons now unknown. The featured image -- a composite of two consecutive images taken from the same location -- was captured last October under a starry sky when the Earth was passing near Mars, making the red planet unusually large and bright. Mars remains visible at sunset, although increasingly close to the horizon over the next few months.

These human shaped stones kind of remind me of the Easter Island statues except that the face looks more like a snake's face instead of a dude's.

There are about 1,300 surviving stone circles in the British isles, dating from about 3,300 BC onwards, along with countless other megaliths. We know very little about how they were used but astronomical alignments are suspected, possibly they were used as calendars as well as ceremonial sites. Some stones may have been aligned to mark the rising or setting of bright stars at particular times of the year. In most cases precise alignments have been lost. Over time weather and animals using them as rubbing posts tends to topple the stones, most we see today have been re-erected sometime over the last couple hundred years.

One thing we can be certain of, the night sky would have played a prominent role in the lives of ancient people.

Here's the Milky Way above the Hurlers on Bodmin Moor, Cornwall. I must go back sometime and have a go at a timelapse.
With lockdown, I've been exploring the moors more and keep blundering into archaeological sites. Sometimes I only notice when I check my position on the google maps satellite view, some features are much easier to make out from the air.

The greatest stone ring structure in the UK, Stonehenge, continually puzzles and surprises us.
It has long been known that the 'bluestones' that make up the circle of smaller monoliths within the extraordinary Sarsen ring were cut from the Preselli Hills in South Wales, nearly 200 miles away, and across the Bristol Channel.

But recently it's been shown that they were first erected to form the Waun Mawn ring, which is now only known by traces. The whole ring of stones were dug up again and moved, in an age without metal tools or wheeled transport. Conquest, religious change - we have no ideas!

You'd think for something billed as a circle of stones I'd be able to find an aerial shot somewhere. But no. I had to resort to google maps: https://www.google.com/maps/place/Duddo ... 125724,86m

And here you can plainly see the vacant space for the other two stones.

Human shaped? Shaped by humans, yes, but I don't see anything resembling a human form or even a human part, except maybe upright clenched fists. And a snake's face? Where?

My first thought was they looked like bad teeth.

Love that starry sky over the Hurlers! I can see the Double Cluster, the Andromeda Galaxy and Cassiopeia!

Thanks, think this was just a 30 second snap with a wide angle lens, with a little light-painting on the foreground. Not much light pollution up on the moors. I now use Sequator for easy stacking of fixed tripod shots, making it possible to get a lot more colour and detail on the Milky Way.

Thanks! Those are great. Now, why didn't they turn up in my searching? (rhetorical question...)

Yeah, that works even better.
