Total lunar eclipse on December 20 or 21, depending on time zone
There is a lunar eclipse on the night of December 20 or 21 – depending on your time zone. See below for the date in your location. This December solstice eclipse is also the northernmost total lunar eclipse for several centuries.
There won’t be a total lunar eclipse this far north on the sky’s dome until December 21, 2485.
That’s because this eclipse is happening almost simultaneously with the December solstice – which in 2010 occurs on December 21 – when the sun will be southernmost for this year. Remember, a totally eclipsed full moon has to lie exactly opposite the sun. The winter sun rides low to the south now, as it crosses the sky each day. So this December full moon is far to the north on the sky’s dome. It rides high in the sky – much like the June solstice sun. Read full story from earthsky.org
Whose Holiday Is It, Anyway?
It’s fundamental to who we are and how we behave. Humans are hard-wired for it.
It brings pleasure to those engaging happily in it, and grief to those who don’t.
Both war and Facebook are rooted in it.
We first become aware of it as toddlers, and spend the rest of our lives either trying to perfect it, wondering why we can’t, or both.
And until individuals understand its evolutionary underpinnings, we’ll never learn how to truly get along with each other.
It’s called ethnocentricity: the tendency to measure other groups according to the values and standards of our own, especially with the belief that one’s own group is superior to others. Read full story from naplesnews.com
The ‘zombie theology’ behind the walking dead
Some people find faith in churches. David Murphy finds them in zombies.
Murphy, the author of “Zombies for Zombies: Advice and Etiquette for the Living Dead,” says Americans’ appetite for zombies isn’t fed just by sources such as the AMC hit series “The Walking Dead” or the countless zombie books and video games people buy.
Our zombie fascination has a religious root. Zombies are humans who have “lost track of their souls,” Murphy says.
“Our higher spirit prevents us from doing stupid and violent things like, say, eating a neighbor,” Murphy says. “When we are devoid of such spiritual ‘guidance,’ we become little more than walking bags of flesh, acting out like soccer moms on a bender.” Read full story from cnn.com
Ending ‘Don’t Ask’ Will Take Time
Congress has repealed ‘Don’t Ask, Don’t Tell,” but the task of lifting the ban against gays serving openly in the military would likely take months, officials said.
Secretary of Defense Robert Gates said in a statement after the Senate voted Saturday to end the policy that he would “approach this process deliberately.”
Once the change becomes law with President Barack Obama’s signature, the military will need to revise policies and regulations that govern everything from leadership training to standards of conduct. And before the policy officially ends, the president, the secretary of defense and the chairman of the Joint Chiefs of Staff must sign a letter certifying that the changes wouldn’t affect military readiness.

President holds pre-meeting with select tribal leaders
WASHINGTON – A select group of tribal leaders from some of the 565 federally-recognized tribal nations invited to join President Barack Obama at his Dec. 16 tribal summit were summoned to meet with the president a day before the main event.
The White House announced the evening of Dec. 15 that 12 tribal leaders had met earlier in the day with the president in the Roosevelt Room. The meeting was closed to other tribal leaders, as well as press.
The president was in the room for approximately 15 minutes. His aides listened to tribal leaders speak for much longer, according to sources familiar with the event. A photo of the session was taken by a White House photographer while the president was in the room.
Complete details of the meeting were unavailable due to the closed nature of the event, but the White House released a statement to publicly document it. The National Congress of American Indians also released a statement. Read full story from indiancountrytoday.com
Got the Winter Blues? Weather’s Effect on Mood Revealed
New research into the connection between weather and moods has started to chip away at old myths as well as uncover some potentially powerful treatments for the winter blues.
The first myth to die is the idea that everyone feels bad when the weather gets foul. It turns out that most people might fall into one of four categories when it comes to their moods and weather, say researchers who have studied more than 2,000 Germans by way of daily questionnaires about their moods and other happenings in their lives.
“We saw differences and we actually categorized people according to their differences,” said Jaap Denissen of Humboldt University in Berlin. He and his colleagues have submitted their latest work, an expansion of an earlier study, to the journal Emotion. Read full story from discovery.com
Beam Me Up: ‘Teleportation’ Is Year’s Biggest Breakthrough
Thanks to physics, and the truly bizarre quirks of quarks, those Star Trek style teleporters may be more than fiction.
A strange discovery by quantum physicists at the University of California Santa Barbara means that an object you can see in front of you may exist simultaneously in a parallel universe — a multi-state condition that has scientists theorizing that teleportation or even time travel may be much more than just the plaything of science fiction writers.
Until this year, all human-made objects have moved according to the laws of classical mechanics, the rules governing ordinary objects. Toss a ball in the air and it falls back to Earth. Drop a coin from your roof and it falls into your yard. But back in March, a group of researchers designed a gadget that moves in ways that can only be described by quantum mechanics — the set of rules that governs the behavior of tiny things like molecules, atoms, and subatomic particles.
And the implication — that teleportation and even time travel may someday, somehow be a reality — is so groundbreaking that Science magazine has labelled it the most significant scientific advance of 2010. Read full story from foxnews.com
Sun’s gravity could be tapped to call E.T.
Our own sun might represent the best communications device around, if only we could harness its power, scientists say.
If the sun’s gravity could be used to create a giant telescope, people could send and receive intensely magnified signals that could allow us to call an alien civilization, some researchers propose.
According to Einstein’s general relativity, the sun’s behemoth mass warps space-time around it, which actually bends light rays passing by like a giant lens. If a detector was placed at the right focal distance to collect the light, the resulting image would be extremely magnified. Read full story from msnbc.msn.com
Celebrate the return of the light with ice lanterns
The way light refracts through ice is fascinating. Forget the science — it’s just plain fun to look at. Flickering light, captured inside an ice lantern, adds a warm and distinctive ambiance to any winter setting. And the gentle glow of fire and light cutting through the dark of winter can take the chill out of the coldest days — at least in spirit.
In Norse mythology, the space where the worlds of fire and ice meet is the place of creation — a place of light, air and warmth. With the arrival of winter solstice and the sun on its slow return, ice lanterns are an easy and fitting way to welcome brighter days.
The formula is simple: Add water to any mold and set it outside or in the freezer. Five-gallon buckets work well if you like the look of a traditional lantern. If you prefer globes, balloons are the way to go. Start now, and with a few supplies and a little patience, you’ll have your own creation ready in time for Christmas or New Year’s Eve. The amount of water you’re freezing and the air temperature will affect how long it takes to make your lantern. The more science you apply — tap vs. distilled water, temperature variances, thin vs. thick walls — the more varied outcomes you can achieve. Read full story from alaskadispatch.com
Why doesn’t the latest sunset fall on the longest day of the year?
If the summer solstice falls on the longest day, why doesn’t it also coincide with the earliest sunrise and the latest sunset?
We all know that the summer solstice, the moment when the sun reaches its most southerly point in the sky, falls on the longest day. So it seems logical that the day would coincide with the earliest sunrise and the latest sunset of the year. But the earliest sunrise tends to happen in early December, while the latest sunset is on another day in early January.
This phenomenon is created by a combination of the Earth’s oval-shaped orbit and its tilt of 23.5 degrees, says Professor Fred Watson, astronomer-in-charge of the Australian Astronomical Observatory.
“These two things together have a real effect on the sunrise and sunset times and they skew them so you don’t have the longest day, the earliest sunrise and the latest sunset all on the same day,” Watson explains. Read full story from abc.net.au
My Take: Religious Cities are Among the Most Violent
In one of the more jarring passages in God is Not Great, the celebrated atheist Christopher Hitchens writes of being asked a “straight yes/no question” by the conservative Jewish broadcaster Dennis Prager. Hitchens was to imagine seeing a large group of men approaching him in a strange city at dusk: “Now – would I feel safer, or less safe, if I was to learn that they were just coming from a prayer meeting?”
Hitchens’ answer, of course, is that he would feel less safe. And the rest of his polemic, which is subtitled “How Religion Poisons Everything,” is an extended attempt to explain why.
Whether religious people are more prone to criminality than unreligious people is, of course, an empirical question. So in some sense it doesn’t make all that much sense to argue about it. Just go instead and look at the data. Read full story from cnn.com
