Astronomy Picture of the Day -- Days in the Sun
NASA ^ | January 21, 2012 | (see photo credit)

Posted on 01/21/2012 4:11:45 PM PST by SunkenCiv

Explanation: From solstice to solstice, this six month long exposure compresses time from the 21st of June till the 21st of December, 2011, into a single point of view. Dubbed a solargraph, the unconventional picture was recorded with a pinhole camera made from a drink can lined with a piece of photographic paper. Fixed to a single spot for the entire exposure, the simple camera continuously records the Sun's path each day as a glowing trail burned into the photosensitive paper. In this case, the spot was chosen to look out over the domes and radio telescope of the University of Hertfordshire's Bayfordbury Observatory. Dark gaps in the daily arcs are caused by cloud cover, whereas continuous bright tracks record glorious spells of sunny weather. Of course, in June, the Sun trails begin higher at the northern hemisphere's summer solstice. The trails sink lower in the sky as December's winter solstice approaches. Last year's autumn was one of the balmiest on record in the UK, as the many bright arcs in the lower part of this picture testify.

It reminds me of the Titanic looming over a ‘futuristic’ city...... I can almost see ‘people’ on the decks.

This link is 21st century internet. Amazing. Thank you!

How do I access this to view my back yard with the same technology?

The winter arcs are pretty low in the sky.

The whole picture looks like tree rings in the sky.

Me too!

I can see the Captain falling into a lifeboat - one arm around a blonde - the other arm filled with bottles of champagne!

How do I access this to view my back yard with the same technology?

Find your back yard on either Google Maps or Bing maps. Bing has oblique photography for a lot of places (as in this case), so it may be your better bet. Once you've got the view you want, click the Share link (Bing) or the chain link icon (Google) and grab the URL it coughs up.

The observatory's web site turns out have a directions page. It has a couple of Google maps showing the observatory. But they're not too useful, given they are just screen shots, not IFRAMES containing live maps. However, up in the corner is SG13 8LD, a UK postal code. UK postal codes are more like ZIP+4 than like ZIP. If you put SG13 8LD into either Google Maps or Bing maps, it takes you right to the observatory.

As for the lat-lon, you can get the exact coordinates from Google Maps. Use the right-click menu to center the map on whatever. Then right-click and copy the link value from the chain-link icon. The coordinates will be found therein, as the ll parameter, e.g., &ll=38.871005,-77.055938.

BTW, if you type a lat-lon number pair into either Google Maps or Bing Maps, it will show you the corresponding spot. Signed decimal degrees seems always to work. Degree-minute-second, N/S and E/W also works, but less reliably.

I see why you thought of the Titanic, potlatch.

It did look like some kind of structure at first glance; if not the Titanic, maybe that Italian cruise ship that tipped over last week? ;’)

I am not sure which impresses me more; the pictuer itselt, or the utter simplicity of how it was taken.

I’ve been reading Danielle Steele’s book about the Titanic and the minute that image appeared that’s what it reminded me of, lol.

Yeah, I had been reading about the Titanic and we are all familiar with the Italian Captian. Didn’t mean to mess up your thread but the image was powerful and “Titanic” looking!
