Tonight’s Starry, Starry Night Sky, Above My Head, During My 11pm 1-Mile Night Walk.

by Anura Guruge



I am relatively lucky in that light pollution, ‘up here’, in the sticks, isn’t too, too bad.

Tonight was cloudless, moonless & the temp. in the mid-50s (F). Dark black sky. Ideal for the stars to shine.

It was mesmerizing. I just love to just look up, stare & wonder. It is amazing.

Took this with my Google Pixel 4 — using its ‘Night Sight‘. To be honest, I expected it to capture more stars. I tried twice. This was it. This, however, does NOT do justice to what I was able to behold.

Think – Today: Why Is There 360 Degrees In A Circle?

by Anura Guruge


thinktodaybanner
360360º in a circle (as opposed to say 100 or 200)? Why? Where did it come from?


Think first, then research, then THINK again. Think for the pleasure of thinking.


Yesterday’s ‘Think’: How many stars can you see naked eye? Lot depends on your own eyesight, where you are and light pollution. There used to be a general consensus that it was (on average) around 3,500 stars. Best case, it would never be over 6,000. But now we have a more definite answer thanks to Yale University professor, Dorrit Hoffleit. She counted all the stars up there with a ‘visibility index’ (so called ‘apparent magnitude’) of 1 to 6.5 — the normal range associated with naked eye visibility. She found a total of 9,096 across BOTH hemispheres, i.e., North & South. So that gives us (roughly) 4,548 a hemisphere. So, the original 3,500 wasn’t a bad guess and probably still holds true given eyesight variation AND increasing light pollution.

Milky Way — When Was The Last Time YOU Saw It?

Do you remember? If you don’t that is very sad and you should try and remedy that ASAHP.

I will confess that I had forgotten how blinking beautiful — and beguilingly mesmerizing — it is!

There is nothing else like it — anywhere.

On Friday, September 2, 2016, on the way to ‘Acadia National Park‘ (for our 3 day visit), I took a detour at 10:30pm to go for a quick (and in my case it is always ‘quick’) run up ‘Cadillac Mountain‘. There were about 15 other vehicles at the top. I got out. The bright lights of ‘Bar Harbor‘ were right in front of I — as I expected.

Then I looked up.

WOW!

Right across, from horizon-to-horizon, straight-up above me — OUR MILKY WAY.

So beautiful.

I had forgotten the delight of seeing it.

Though it must have been visible when I was growing up in Ceylon I can’t recall it in the context of my childhood.

I know/remember that I only started being aware of the Milky Way when I moved to the United States in 1985 — living in very rural, farm-country Maryland (about 30 miles from a city). I used to love looking up and seeing it.

I know it was visible in Southern New Hampshire when I moved here in September 1986 — again to a very rural area at the time.

But now, though I still live in what is a rural area, on a dirt road, I no longer see the Milky Way. Light pollution is BAD up here. Why people who are afraid of the dark decide to live on dirt roads baffle me. Stay in the City with bright lights. Don’t move next door to me and put up 40 solar powered garden lights.

New Hampshire. The ‘white dot on the blue arrow‘ is ME.
You can see the pollution encroaching.
Compare with this map from 4 years ago.

Acadia National Park area. The ‘blue arrow with white dot’ is Bar Harbor.

The Purple swatches denote THE PARK — not light pollution!
Hence the Purple in Schoodic Peninsula (to the right) and Isle au Haut (southwest).

The Milky Way when there is no light pollution — from ‘National Geographic’. Click to read thought provoking article.


Maybe it hits me the hardest because I only saw the Milky Way as an adult when I came to the U.S. (on my 2nd time around) in 1985 and lived way, way, way out in the sticks in rural Maryland, about 30 miles west of Baltimore. There is too much light pollution in Europe unless you can get way out (and then in the U.K. you have the clouds).

Yes, you can still see it, quite well, from the Lakes Region if you are lucky. But, totally unnecessary, totally uncalled for light pollution is becoming more and more of a problem.

We live on a dirt road. In the 27 years I have been in the U.S. (this time around), for 63% of that time. I have never had town water in any of the 6 homes I have owned in that time. 4 of them also had septic tanks. So I have always lived out in the sticks. Part of it, certainly, was the reaction of moving here from the U.K., which being a small country is considerably more congested.

What really confounds me is people who move to dirt roads, like the one we live in now, only to discover that they are afraid of the dark! So they have to have all these lights on to make them feel safe and secure. Cracks me up.

The guy next door is the worst. From what I can see he lived in parsonages, in the middle of town, for the last 25 years. He appears to be petrified of the dark. I went out last night at 10:45 pm to walk the dogs. His yard was lit up like Time’s Square. There is nobody around. It is 10:45. This is the country. But, he is not alone.

All of our neighbors seem to abhor the dark. They love those solar powered lights. I can even tolerate those since they are not bright. But, for some those are too tame. One of the neighbors, diagonally across, keeps his outside lights on all night, every night, year round. In winter he turns on a bright, outdoor spotlight that stays on 24/7 from October till April. They, who moved here from Nashua, don’t like the dark. That spotlight lights up our house and yard. More than once I had thought about sending him a check for about $30 to defray his electric bill because when that light is on I don’t have to use any of my outside lights. I just use his spare light.

I just wish people would give some thought to light pollution. It is a form of pollution. I am not the only one concerned. Even NASA is worried.
