Lost in space: The hope to walk around on Mars

By Dana Wilde on May 20, 2012, at 4:18 p.m.
Every so often in these pages I come staggering out of the woods with twigs in what’s left of my hair and caterpillars angling up my socks and my eyeballs dilated and aiming in different directions with notions of sinister household vehicles or what computer is trying to seize control ...

Notes on the 150th anniversary of Thoreau’s death

By Dana Wilde on May 06, 2012, at 4:04 p.m.
April was not as cruel this year as last (when by the 15th there were still 2 feet of snow in the Troy woods, if memory serves). This time winter almost kept us warm, comparatively, with no snow well into January and strange tangles of bare branches growing like botanical ...

NGC 1999, a reflection nebula, shines because the light from an embedded source illuminates its dust, in this case a bright, recently formed star, visible just to the left of center in this Hubble Space Telescope image from the constellation Orion.

The philosophy and science of putting clouds in focus

By Dana Wilde on April 22, 2012, at 1:19 p.m.
If you give your eyes a little while to get adjusted to the night sky, there soon starts to be more than just great sprays of lights. Here and there, when conditions are right — meaning when the sky is free of scud that gets in the way and of ...

Even in a mild spring, the dogs of April stubbornly keep watch on the driveway, and the hope of an end to winter, in Troy.

The dogs of April

By Dana Wilde on April 08, 2012, at 4:44 p.m.
This is the time of year when winter does not want to let go of its grip, like a mean dog. When the sun is out and the wind is still, it feels like May. But if you speak too soon the wind bites you two months back to the ...

Forces of nature

By Dana Wilde on March 24, 2012, at 5:42 p.m.
I remember looking up one night decades ago through broken clouds, with icy snow underfoot, and feeling afraid. The kind of fear that creeps along the back of your neck and clogs your throat. It was a star, one pin of light among thousands, unimaginably far away. Huge distances are ...

Amateur Naturalist: The Dog Star

By Dana Wilde on March 11, 2012, at 3:48 p.m.
You know Orion always comes up sideways. Throwing his leg up over the Dixmont hills he strides into the evening sky and by about 11 p.m. in winter you can see his dog behind him, too, with legs outstretched and a large bright star in its shoulder. Sirius, the star ...

Stars stream through the sky in a 38-minute exposure over Acadia National Park in 2008. Once you get your vision oriented, a lot of information starts streaming in from the night sky.

Messages in starlight

Just a few points of orientation are enough to find your bearings among the roughly 6,000 stars your eye can pick out in a black sky, clear of city lights. About 300 of the brighter ones have names, such as Polaris, Sirius and Vega. The rest are known to astronomers ...

Orienting yourself to the stars

By Dana Wilde on Feb. 12, 2012, at 4:50 p.m.
The key to stargazing is points of orientation. In the beginning, like for all beginnings, you take the simple points first, which in the case of stargazing is simply the brightest stars. There are two ways to use the bright stars, and like practically everything else in the universe, the ...

This budding lilac bush in Hampden last week appears to think it is already spring. Is it a sign of global warming? Maybe. Only people who are conversant with all the facts can say for sure.

My theory of climatology and the driveway

By Dana Wilde on Jan. 29, 2012, at 5:13 p.m.
Two weeks later the snow was gone again. At least, gone from all of central Maine except our house in Troy, where before Friday’s rainsnow there was still an icy crust under the firs and spruces. As noted here before, it has snowed this winter, but the catch has been ...

A dark and reckless winter

By Dana Wilde on Jan. 14, 2012, at 6:44 p.m.
Winter is a dark and reckless thing, even when it’s half asleep. By which I mean, of course, the lack of snow cover in most of Maine through the middle of last week. At my house in Troy, we’ve had disturbingly mixed feelings about this. In one way, we’ve felt ...

The once and future pole star

By Dana Wilde on Jan. 01, 2012, at 7:42 p.m.
The great weight of winter is bearing down on us again. For younger readers this will be little more than an old guy’s grouchy personal mythology stinging their ears. But the more years you’ve lived through the apparently interminable stretch from December to March, the more the cold seems to ...

Winter frontiers

By Dana Wilde on Dec. 18, 2011, at 4:39 p.m.
The day before the November snowstorm, a few vestiges of summer dangled like bits of grass and twigs in autumn’s last spider webs. A lone yellow hawkweed, contracted against the cold, looked up out of the grass by the gravel walk. A little viney beast with tiny white blossoms and ...

Two galaxies colliding about 220 million light-years from Earth toward the constellation Aquarius have formed the object NGC 7252, informally called by astronomers the Atoms-for-Peace galaxy because it reminds them of a drawing of an atom. NGC 7252 spans about 600,000 light-years.

When particles collide

By Dana Wilde on Dec. 04, 2011, at 9:34 p.m.
Everything is interacting. People are interacting with their cars and cats and jeejahs, with the woods, with each other. Mosquitoes are interacting with dragonflies. Blue jays with sunflower seeds. Roots with soils. Sunlight with raindrops. Moons with planets, planets with stars, stars with galaxies, and galaxies with more galaxies. The ...

Streaks of light on film: The real particles produced by the collision of a 6400 GeV sulphur ion with a gold target pass through a streamer chamber. Streamer chambers consist of a gas chamber through which a strong pulsed electric field is passed, creating sparks as a charged particle passes through it.

Models of behavior

By Dana Wilde on Nov. 20, 2011, at 10:04 a.m.
One of the easiest things to understand in chemistry is the model of an atom. An atom is like a mini solar system. It has a nucleus, which is like the sun, and electrons whirling around the nucleus, like planets. After this it gets complicated fast, and since I am ...

An old bee on the edge of the driveway

By Dana Wilde on Nov. 06, 2011, at 8:24 p.m.
Beside the driveway in late September, I stopped to watch a red-tailed bumble bee pore over some New England asters, bright purple-blue-rayed medallions in tight clusters. He was making his way over each blossom, methodically prodding each dusky orange central disk. He was working very slowly, gathering what nectar he ...

Halloween morning

I get out of bed and make coffee, then sit in front of the computer. I spend much of the morning complaining to two friends. They seem to understand what I say. They are a dying breed, and they live hundreds of miles away. Why do they listen to this ...

This spring peeper came out from under some cold stone in Troy and got lost this August. Note the toes, suitable for use in witches hell-broth.

The usual summer frameworks were somewhat disjointed this year. Around our house snowbanks lingered into May, the timing of some wildflowers was way off — starflowers weeks late, lupines a month early — and in the end I did see small green rose hips at the end of July, which ...

Cat karma

A few Sunday mornings ago, we went outside to the deck for our coffee and found a familiar sight: The two cats, Brian and Panda, were sleeping under the chairs in the warm, bugless morning air. A little earlier they had eaten their complimentary canned-food breakfast. The bear-cublike orange one, ...

September sunset and goldenrod in Unity

Thoreau, Poe and September

By Dana Wilde on Sept. 11, 2011, at 9:23 p.m.
The first bite of fall in Troy this year came Sept. 7, a Wednesday. Just a slight tell-tale chill rolling through the kitchen window, like a nip on the ear. Birch leaves were already strewing the deck, and the sumac had been reddening since August – it always gives in ...
