That's truly horrifying but I so believe it. At least the part about
clouds due to changing weather patterns. The way air travel is going,
maybe we'll also have been the last generation to fly.
Finished rebuilding my scopes in the summer of 2005. All of them - a
6" f5 and 8" f6, a 12 1/2' f6, my 20" f5.7 as a tri., as well as all
their finders, etc. It took me almost two years to rebuild them all.
Spent this summer building 3 equatorial platforms. But who knew that the
Cypress Hills Star Party in August 2004 would have been pretty much the
last clear nights that Edmonton, Canada would see. Nearly 1 1/2 years
after finishing the scopes, 2 1/2 years after Cypress, Edmonton has had
no more than literally just a handful of clear, moonless nights. Haven't
looked thru the 20" once. Treed-in urban dweller. Long drive to my dark
sky site. Have had the little scopes out in the back yard a couple times
to see how they work. Checked out Saturn with the 12" but the seeing
was horrible.
Two and a half years of cloud...
We do have "clear" days. They have high thin cloud mostly. Sometimes
the evening is clear but the clouds roll in as darkness comes. Sometimes
it's solid clouds until they roll off at dawn. We had a pretty nice
summer, but we're far enough north that we get a mid-summer perpetual
twilight where for a nearly 6 weeks the night sky is so bright that the
only stars you can see are as bright as the Summer Triangle and
Arcturus. Not great for deep sky.
It's not only suicidally depressing for observers, it's been just
awful for gardens (co-inciding with a drought that's entered its 7th
year), and I think it has to take some toll on the general population as
well, even if the clouds are often just high and thin.
I have started having a recurring dream: that I wake up in the
middle of the night and that the sky is black and the stars are
brilliant, like they were when I was a kid in the 60s, and I drag out a
scope, and it's just a wonderful, wonderful... dream. But I realize just
now that even that dream hasn't come back for a while. Sigh. I guess
I've given up hope at all levels.
So if you do have a dark sky full of stars, enjoy it. While you can.
It may be that ground-based astronomy across the world could end in 40
years. It may be that ground-based astronomy could end at an observatory
near you much, much sooner than you'd ever believe.
