Stars and Mars


Daylight veils and night-time reveals the most majestic sight of the planet Mars, like a huge red star, rising in the east soon after dark, dominating the sky. It's at its closest to the Sun right now, meaning that it's at its closest to us, and on the 16th was precisely aligned with the Earth and Sun. Oh! I tried so hard to get a photo showing how I felt when this planet appeared in the eastern windows each night, persisting, as if it wanted something. I'll give it! (This is the best my camera could do; there's a more awesome photo here.)

Dominating the southern sky not long ago were the two brilliant planets Jupiter and Saturn, so bright in the bedroom window that after settling in I got back up and went out to look at them. They're headed west, sinking soon after sunset. On December 21 (winter solstice!), look low in the southwest at sunset, and Jupiter and Saturn will be in a rare conjunction at 0 degrees of the sign Aquarius. This is also called "the Great Conjunction" and occurs every 19.6 years. Astronomers say that the star the Magi noticed and followed was a Jupiter-Saturn conjunction.

This 2020 at least the planets are with us and want to entertain us!

The Homeless Telescope

We'd not seen each other in 10 years, but a Facebook friend, a city resident, knew I liked stars and one day messaged and asked if I wanted a telescope. I have always wanted a telescope. We met and placed the entire assembly in my car's trunk because neither of us knew how to separate the telescope from the tripod -- and if we did we might not know enough to reassemble it.

It's a 114mm Polaris by Meade reflector telescope, and somebody bought it and never used it and gave it to my Facebook friend who kept it in his garage hoping to use it but never did. It looked quite too noble to be homeless.

Before even daring to clean the dust from it I'm trying to learn whether it's salvageable. First, telescopes shouldn't be left outside, especially not in garages that can get very hot. Only my porch or my heart have any room. I figured if it's been garaged for a couple of years staying on the porch awhile wouldn't do much further harm. The buyers' reviews said it's a beginner's telescope but good quality for the price, about $150 new. The knob sticking out on the right is a counterweight.

Looking down into the eyescope I discovered it lacks an eyepiece. New telescopes come with a set of 3 eyepieces, but this model of Polaris had cheap ones I can replace with better-quality eyepieces for about $20. The eyepieces are everything. The telescope's focus is permanently set to "infinity." That I liked. There is at least one scientific-looking ring marked in increments, in white paint, 0-360.

I also learned you can buy new telescopes controllable with your phone. Using an app, enter the desired astral object and the telescope will find it automatically. But one cannot use those 'scopes manually. Without Wi-Fi there'd be no stargazing.

Ahead: more learning, and maybe some joy. If I can restore and master this one, I can master a finer one.

Comet Lovejoy

skyandtelescope.com 

A friend said "Follow Orion's belt up to the Pleiades" and to their right -- with binoculars or a telescope, because this rare visible-to-the-naked-eye comet is at its brightest right now, today, at magnitude 3.8. That's not very bright; the North Star is much brighter at magnitude 1.97. About 11:15 p.m. last night in the marvelous 99 percent darkness we have here (except for the headlights on passing cars) I searched with my 8x binoculars. Didn't find the comet.

Back in the house I consulted the Google Sky map. It's not on there! Googled it, learning its name -- Comet Lovejoy, how wonderful! -- at skyandtelescope.com, and their map showed the comet's location and trajectory for every day of January--currently to the right of the Pleiades, just as I was told. The page had wonderful astronomers' photos of the comet, which is bright green. Out again but did not find it. Kept looking to the right of the Pleiades. Now I'd been looking for an hour. I knew it was out there. Back indoors, looking at the same map.

The temperature, above freezing, was tolerable, so I went out again because I hate to give up on anything. Carefully, carefully I  swept the sky with its shovelsful of stars. This time I recalled that the sky is a curved shell and "to the right"--as the stars progress westward--will also mean "downward." At last, at last: I found it. A smeary little wad of light, no tail, not visibly green, but rather the color of Vaseline. Beautiful, to me!
