Thoughts for the new year,

but before that think about this

The oddest celestial event?

This year there's an easy winner. It's the millennium's first total lunar eclipse completely visible from all of North America and Hawaii. And whoa, beat the drums, it happens right on the solstice.

12/21/2010

This was exactly the kind of spectacle that inspired the fun-loving Mayans to push their most annoying relatives off pyramids. (Does any scholar actually know how they selected people for sacrifices? "Annoying" seems logical.) These days, our own citizenry is much too overweight to engage in such energetic rituals. But if you're tempted, be sure to first check local ordinances before you perform even a single goat sacrifice.

At midnight December 20/21, we'll have the highest Full Moon until 2020. From the West Coast, that Moon will be in total eclipse at midnight — how cool is that?

We'll also get a rare chance to gauge the Full Moon's brightness. During the night's first half, it defiles the sky with a creamy glow that obliterates everything fainter than 3rd magnitude. Then, if you live in the country away from streetlights and other light pollution, behold the metamorphosis. Drink in the glory of the winter Milky Way after the Moon's been reduced to a coppery phantom, with the visible star count boosted from 120 to 2,600.

Earth's shadow usually appears red. So the Moon becomes copper when fully immersed. Yet the initial "bite" as the event begins always looks inky black. Culprit: our retinas. When the sunlit portion is still fat and brilliant, our eyes underexpose the shadowed part. As you watch the eclipse progress, it's fun to note when the ebony starts becoming reddish, about halfway through the event.

The eclipsed Moon doesn't have to be red. It can be pale pink, beige, or even black so that it vanishes altogether. It all depends on clouds and dust around Earth's edge, or limb. This is the only occasion when a celestial body gives us a report card about our planet. Coppery red means everything is normal. Black means dust from the Iceland volcano and perhaps China's industrial pollution has dirtied our air big time. Green means you didn't set the alarm and are dreaming the whole thing.

Now for the ancient debate over equipment. People often fail to appreciate things that are free, so maybe they'll find this event enhanced through their most expensive telescope and largest 14-pound eyepiece. In my opinion, however, a lunar eclipse looks best with either the naked eye or else image-stabilized binoculars.

The Moon will occupy a very special place in the heavens that night. Our sky is a carnival of intersecting planes. There is the flat plane of our solar system seen edgewise, defined by the ecliptic. Then there is our galaxy's disk, the Milky Way. These eternal planes meet and cross at the Taurus-Gemini border. Astoundingly, a third plane called the solstitial colure — the sky-circling meridian running through the celestial poles in the precise direction of Earth's tilt — is right there, too.

It's an implausible three-way intersection. And yet that is where — within a few degrees — the Full Moon will stand during the eclipse.

So the Moon will be eclipsed while aligned with the galaxy's plane, Earth's tilt axis, and the centerline of our solar system all at once. Are you kidding? The Mayan priests would have tossed extra people.

The three sky-lines intersect in a teensy triangle that manages to surround NGC 2129, an open cluster 7,000 light-years away. Use your go-to telescope to locate those baby stars near the eclipsed Moon. Because the heavens will be nice and dark, deep-sky lovers take note: At mid-eclipse (3:17 a.m. EST), the ruddy Moon sits exactly halfway between Gemini's Rolls-Royce cluster M35 and Taurus' freakish Crab Nebula (M1).

Can you imagine the uproar from the paranoid and gullible if this notable display had coincided with the Mayan calendar flip? Then they'd be sure it's Armageddon-time. Happily, no eclipse or conjunction will occur 2 years from now on December 21, 2012. To show your gratitude, that non-event deserves an additional goat sacrifice.

One more thing. The Full Moon's hot surface aims infrared radiation our way like a bathroom heater. This makes Earth's lower atmosphere 4/100° warmer whenever the Moon is full. Will we lose this warmth during the eclipse? Let's bring along our high-tech lab thermometers that night and really puzzle onlookers.

Thad, thanks for your very interesting and cleverly written post. It was especially nice to see a post about astronomical phenomena that was free of astrological and other paranormal codswallop. Such a rarity here in Waccoland--refreshing!

For thinking people the Winter Solstice is the beginning of the new year, there is a tradition of making resolutions on

new years eve that so often fall away into the distractions of living.

As to a significant moment to hang a resolution on,

this one takes the cake,

for new years day to begin in the midst of a dead on eclipse is remarkable

When the Moon goes dark remember all that light is still there streaming by the shadow as an analogy of the darkness of

these days, remember how much light surrounds you and is there to call on, find hope in that and rise to your dreams that

have fallen behind in these darkened days of dire sway

This year's winter solstice will coincide with a full lunar eclipse in a union that has not been seen in 456 years.

The reappearance of the celestial eccentricity -- an event that will occur on Tuesday -- holds special significance for

spiritualities that tap into the energy of the winter solstice, the shortest day of the year and a time that is associated with the

Rebirth of the sun.

"It's a ritual of transformation from darkness into light," says Nicole Cooper, a high priestess at Toronto's Wiccan Church of

Canada.

Ms. Cooper said Wiccans also would see great significance in the unique coupling of the masculine energy of the sun and the

feminine energy of the moon.


The last time the two happened at the same time was in 1554, according to NASA.

The eclipse will start just after 10:30, with the full eclipse at midnight

Ah, 1554, I remember it well. The goats, the annoying relatives, the unique coupling.... lol
