Distant Dwarf Planet Secrets Revealed


Orbiting at the frozen edges of our solar system, the mysterious dwarf planet Makemake is finally coming out of the shadows as astronomers get their best view yet of Pluto's little sibling.

Discovered in 2005, Makemake—pronounced MAH-keh MAH-keh after a Polynesian creation god—is one of five Pluto-like objects that prompted a redefining of the term "planet" and the creation of a new group of dwarf planets in 2006. (Related: "Pluto Not a Planet, Astronomers Rule.")

Just like the slightly larger Pluto, this icy world circles our sun beyond Neptune. Researchers expected Makemake to also have a global atmosphere—but new evidence reveals that isn't the case.

Staring at a Star

An international team of astronomers was able for the first time to probe Makemake's physical characteristics using the European Southern Observatory's three most powerful telescopes in Chile. The researchers observed the change in light given off by a distant star as the dwarf planet passed in front of it. (Learn how scientists found Makemake.)

"These events are extremely difficult to predict and observe, but they are the only means of obtaining accurate knowledge of important properties of dwarf planets," said Jose Luis Ortiz, lead author of this new study and an astronomer at the Instituto de Astrofisica de Andalucia, in Spain.

It's like trying to study a coin from a distance of 30 miles (48 kilometers) or more, Ortiz added.

Ortiz and his team knew Makemake didn't have an atmosphere when light from the background star abruptly dimmed and brightened as the chilly world drifted across its face.

"The light went off very abruptly from all the sites we observed the event so this means this world cannot have a substantial and global atmosphere like that of its sibling Pluto," Ortiz said.

If Makemake had an atmosphere, light from the star would gradually decrease and increase as the dwarf planet passed in front.

Coming Into Focus

The team's new observations add much more detail to our view of Makemake—not only limiting the possibility of an atmosphere but also determining the planet's size and surface more accurately.

"We think Makemake is a sphere flattened slightly at both poles and mostly covered with very white ices—mainly of methane," said Ortiz.

"But there are also indications for some organic material at least at some places; this material is usually very red and we think in a small percentage of the surface, the terrain is quite dark," he added.

Why Makemake lacks a global atmosphere remains a big mystery, but Ortiz does have a theory. Pluto is covered in nitrogen ice. When the sun heats this volatile material, it turns straight into a gas, creating Pluto's atmosphere.

Makemake lacks nitrogen ice on its surface, so there is nothing for the sun to heat into a gas to provide an atmosphere.

The dwarf planet has less mass, and a weaker gravitational field, than Pluto, said Ortiz. This means that over eons of time, Makemake may not have been able to hang on to its nitrogen.

Methane ice will also transform into a gas when heated. But since the dwarf planet is nearly at its furthest distance from the sun, Ortiz believes that Makemake's surface methane is still frozen. (Learn about orbital planes.)

And even if the methane were to transform into a gas, any resulting atmosphere would cover, at most, only ten percent of the planet, said Ortiz.

The new results are detailed today in the journal Nature.

Water Polo: Shock win for S'pore at Asian Swimming Championships






SINGAPORE: A bronze medal-finish from the 1986 Asian Games remains the most recent international result of note for the Singapore men's water polo team.

But that may soon be bettered.

This is because the Republic are on course to reach the semi-finals at the 9th Asian Swimming Championships in Dubai after skipper Eugene Teo's (picture) hat-trick propelled them to a shock 8-7 win over Asian powerhouse Uzbekistan on Wednesday (Thursday morning, Singapore time).

On Thursday night, they lost 23-2 to world No 6 China, who had beaten Uzbekistan 28-6 in an earlier Group A match. Nonetheless, Singapore are expected to reach the quarter-finals as group runners-up to China, where they are likely to face Thailand from Group B.

Despite the defeat, team manager Samuel Wong described their win over Uzbekistan as a long-awaited "breakthrough" for the 24-time SEA Games champions - they have won the title every time since 1965 - who have often been criticised for failing to replicate their regional dominance at the continental level.

"We've always done well at the SEA Games, but have been nowhere in Asia for a long time," he said. "But this has proved we can dream big. Hopefully, this would also help increase interest in the sport in Singapore."

Singapore Sports Council Chief Executive Officer Lim Teck Yin, a member of Singapore's 1986 Asiad side, added: "It's an exciting result. Some of the players are as young as 17, and to achieve this speaks a lot about the maturity of their game."

Coached by Lee Sai Meng, Singapore had also drawn 8-8 with Saudi Arabia and beaten Sri Lanka 24-4.

"We started the tournament slowly ... (but) the team, especially goalkeeper Byron Quek, was excellent and once the Uzbeks realised they weren't getting much luck against us, their confidence dropped and ours rose," said Wong.

To prepare for the meet, the squad played in the China National League earlier this year, and also went on a training stint in Guangzhou.

A Singapore Sports Institute sports science team are also in Dubai to provide support.

However, Lim has called the team not to be carried away with their results at the Asian Championships - not when the SEA Games will be held in Myanmar.

He said: "People may say the SEA Games isn't important anymore, but we'll be under pressure to keep our run going. Hopefully this will be the impetus to build belief that if they keep working hard, they can achieve a lot."

David Headley shadow over resumption of cricketing ties with Pakistan

NEW DELHI: The government on Thursday sounded a word of caution about the resumption of cricket ties with Pakistan saying that one of the main 26/11 accused, David Coleman Headley, had entered India on the pretext of watching matches. Minister of state for external affairs E Ahmed said the issue of visas to Pakistani nationals coming to India to watch cricket matches at various venues will be in accordance with "extant rules and regulations".

"India continues to make efforts to build peaceful and stable relations with Pakistan," said Ahmed, a day after India hanged Ajmal Kasab, one of the perpetrators of Mumbai attacks. "This includes promotion of sporting ties. However, terrorism against India emanating from Pakistan and territory under its control remains a core concern for us," he added.

Government has given clearance to BCCI for Pakistan cricket team's tour to India to participate in three One Day Internationals (ODIs) and two T20 matches from December 25 to January 6. The matches will be played in Bengaluru, Ahmedabad, Delhi, Chennai and Kolkata.

"As per available information, two alleged conspirators of Mumbai terror attack, as revealed by David Coleman Headley, visited New Delhi in 2005 on the pretext of watching India-Pakistan cricket match," said Ahmed.

According to the minister, the government has conveyed to the Pakistan leadership, including at the highest levels that Islamabad must abide by its commitment that it will not allow its territory and territory under its control to be used for aiding and abetting of terrorist activities against India and for providing sanctuaries to such terrorist groups. "It has also been conveyed to Pakistan that an expeditious and successful conclusion of the investigation and trial relating to those involved in the Mumbai attacks would be a major confidence building measure and would help bridge the trust deficit," he added.

2 Dead, Dozens to Hospital After 100-Car Pileup













At least two people died and more than 80 were injured after a 100-plus car pileup in Texas today, according the Department of Public Safety.


A man and a woman died from their injuries, ABC News affiliate KBMT-TV reported. Their names were not immediately available.


The DPS said it won't know the exact number of cars involved in the pileup until officials finish untangling the wrecks.


At least five people who were taken to the hospital are in critical condition, KBMT reported.

The accident happened in Jefferson County shortly after 8 a.m. Thanksgiving morning on Interstate 10 between Taylor Bayou and Hampshire Road.


Fog blinded drivers, with investigators saying most couldn't see a foot in front of them at the time of the crash.


"The cause of the accident was a heavy fog bank rolled into this area this morning, which caused nobody to be able to see and caused one accident that triggered another accident and then a chain reaction," said Deputy Rod Carroll of the Jefferson County Sheriff's Department.


"Even as the deputies were pulling up we still had a continuous chain of accidents," Carroll said.


An 18-wheeler tanker truck began leaking after the chain-reaction accident, KBMT reported.


The eastbound side of the freeway was closed for hours and remained closed into the afternoon, DPS told ABC News. The westbound lanes opened shortly after noon.

Football: Galatasaray end United's unbeaten run






ISTANBUL: Galatasaray ended Manchester United's perfect start to this season's Champions League with a 1-0 victory in Group H in Istanbul on Tuesday.

Burak Yilmaz scored the only goal of the game at the Turk Telekom Arena when he headed in a corner in the 54th minute to take the hosts to the brink of qualification for the knockout stages

But with United already through to the second phase, this match allowed manager Alex Ferguson to give several younger players some valuable European experience in front of some of the continent's most passionate fans.

"The possession was good and the attacking play was good," Ferguson told Sky Sports. "We had one or two good opportunities in both halves.

"They had a few strikes from outside the box and our goalkeeper did well. Otherwise we coped well."

United stars such as England striker Wayne Rooney, top scorer Robin van Persie, Rio Ferdinand, Patrice Evra, Paul Scholes and Ryan Giggs, the only survivor from the 1993 'Welcome to Hell' trip to Istanbul, stayed in Manchester.

By contrast, Tuesday saw Nick Powell, at 18 years and 242 days, become the second youngest Englishman to feature for United in the Champions League.

The fact that record is held by Kieran Richardson should warn Powell that Tuesday's appearance is no guarantee of Old Trafford stardom.

Meanwhile, Phil Jones made his first United appearance of the season and Powell his first start.

A first half of few chances saw United keeper Anders Lindegaard make just the one save, turning away a curling Hamit Altintop shot.

But the match livened up considerably after the interval with former Liverpool player Albert Riera testing Lindegaard from long range before the Dane did well to tip Felipe Melo's header over the bar.

But the ensuing corner saw Filmaz find space on the edge of the six-yard box before steering in a header.

The margin of defeat could have been worse for United, with Altintop's powerful long-range shot rattling the crossbar.

Ferguson tried to conjure an equaliser by introducing Ashley Young, Federico Macheda and Joshua King off the bench but it made no difference to the result.

Cyclists set out for green GDP

SILIGURI: A group of environmental activists set out from here on a 2,000km awareness yatra on Tuesday to press for the introduction of what they are calling gross environmental product (GEP), a measure similar to GDP for monitoring India's natural resources.

The 11-member team will travel on bicycles from Siliguri in north Bengal to Dehradun in Uttarakhand, covering the distance in 40 days. They will hold meetings along the way to spread the word on why India needs to track its natural resources such as water, air, soil, forests etc.

"Only a stable ecology can lead to a stable economy. Just as the government releases GDP figures, it should also come out with an annual GEP, which would be a tabulation of how each of our natural resources was spent in that year," said Anil P Joshi, who is leading the yatra. The group, consisting of activists aged 19 to 72, would be travelling through Patna, Varanasi, Allahabad, Kanpur, Mathura and Delhi, interacting with people to popularize the demand for GEP. "Our mission is to create mass awareness about the need to formulate an ecological growth measure so people know about the health of India's environment," said Joshi, a Padma Shri-awardee who runs a Dehra Dun-based NGO, Himalayan Environmental Studies and Conservation Organization.

GEP is somewhat similar to the concept of a 'green GDP' — gross domestic product after being adjusted for environmental costs of economic activity — which the Union environment ministry hopes to roll out by 2015.

The team would cross 55 districts and more than a 1,000 villages to reach the Himalayas. "Our other motto is save the Himalayas. For ages, this mountain range has been providing life to 65% of Indians. Today, Himalayan ecology is threatened and we wish to raise awareness about what this means for people living in the plains," Joshi said.

Thanksgiving 2012 Myths and Facts


Before the big dinner, debunk the myths—for starters, the first "real" U.S. Thanksgiving wasn't until the 1800s—and get to the roots of Thanksgiving 2012.

Thanksgiving Dinner: Recipe for Food Coma?

Key to any Thanksgiving Day menu are a fat turkey and cranberry sauce.

An estimated 254 million turkeys will be raised for slaughter in the U.S. during 2012, up 2 percent from 2011's total, according to the U.S. Department of Agriculture's National Agricultural Statistics Service. Last year's birds were worth about five billion dollars.

About 46 million turkeys ended up on U.S. dinner tables last Thanksgiving—or about 736 million pounds (334 million kilograms) of turkey meat, according to estimates from the National Turkey Federation.

Minnesota is the United States' top turkey-producing state, followed by North Carolina, Arkansas, Missouri, Virginia, and Indiana.

These "big six" states produce two of every three U.S.-raised birds, according to U.S. Census Bureau data.

U.S. farmers will also produce 768 million pounds (348 million kilograms) of cranberries in 2012, which, like turkeys, are native to the Americas. The top producers are Wisconsin and Massachusetts.

The U.S. will also grow 2.7 billion pounds (1.22 billion kilograms) of sweet potatoes—many in North Carolina, Mississippi, California, and Louisiana—and will produce more than 1.1 billion pounds (499 million kilograms) of pumpkins.

Illinois, California, Pennsylvania, and Ohio grow the most U.S. pumpkins.

But if you overeat at Thanksgiving dinner, there's a price to be paid for all this plenty: the Thanksgiving "food coma." The post-meal fatigue may be real, but the condition is giving turkeys a bad rap.

Contrary to myth, the amount of the organic amino acid tryptophan in most turkeys isn't responsible for drowsiness.

Instead, scientists blame booze, the sheer caloric size of an average feast, or just plain-old relaxing after stressful work schedules. (Take a Thanksgiving quiz.)

What Was on the First Thanksgiving Menu?

Little is known about the first Thanksgiving dinner in Plimoth (also spelled Plymouth) Colony in October 1621, attended by some 50 English colonists and about 90 Wampanoag American Indian men in what is now Massachusetts.

We do know that the Wampanoag killed five deer for the feast, and that the colonists shot wild fowl—which may have been geese, ducks, or turkey. Some form, or forms, of Indian corn were also served.

But Jennifer Monac, spokesperson for the living-history museum Plimoth Plantation, said the feasters likely supplemented their venison and birds with fish, lobster, clams, nuts, and wheat flour, as well as vegetables, such as pumpkins, squashes, carrots, and peas.

"They ate seasonally," Monac said in 2009, "and this was the time of the year when they were really feasting. There were lots of vegetables around, because the harvest had been brought in."

Much of what we consider traditional Thanksgiving fare was unknown at the first Thanksgiving. Potatoes and sweet potatoes hadn't yet become staples of the English diet, for example. And cranberry sauce requires sugar—an expensive delicacy in the 1600s. Likewise, pumpkin pie went missing due to a lack of crust ingredients.

If you want to eat like a Pilgrim yourself, try some of the Plimoth Plantation's recipes, including stewed pompion (pumpkin) or traditional Wampanoag succotash. (See "Sixteen Indian Innovations: From Popcorn to Parkas.")

First Thanksgiving Not a True Thanksgiving?

Long before the first Thanksgiving, American Indian peoples, Europeans, and other cultures around the world had often celebrated the harvest season with feasts to offer thanks to higher powers for their sustenance and survival.

In 1541 Spaniard Francisco Vásquez de Coronado and his troops celebrated a "Thanksgiving" while searching for New World gold in what is now the Texas Panhandle.

Later such feasts were held by French Huguenot colonists in present-day Jacksonville, Florida (1564), by English colonists and Abnaki Indians at Maine's Kennebec River (1607), and in Jamestown, Virginia (1610), when the arrival of a food-laden ship ended a brutal famine. (Related: "Four Hundred-Year-Old Seeds, Spear Change Perceptions of Jamestown Colony.")

But it's the 1621 Plimoth Thanksgiving that's linked to the birth of our modern holiday. To tell the truth, though, the first "real" Thanksgiving happened two centuries later.

Everything we know about the three-day Plimoth gathering comes from a description in a letter wrote by Edward Winslow, leader of the Plimoth Colony, in 1621, Monac said. The letter had been lost for 200 years and was rediscovered in the 1800s, she added.

In 1841 Boston publisher Alexander Young printed Winslow's brief account of the feast and added his own twist, dubbing the 1621 feast the "First Thanksgiving."

In Winslow's "short letter, it was clear that [the 1621 feast] was not something that was supposed to be repeated again and again. It wasn't even a Thanksgiving, which in the 17th century was a day of fasting. It was a harvest celebration," Monac said.

But after its mid-1800s appearance, Young's designation caught on—to say the least.

U.S. President Abraham Lincoln declared Thanksgiving Day a national holiday in 1863. He was probably swayed in part by magazine editor Sarah Josepha Hale—the author of the nursery rhyme "Mary Had a Little Lamb"—who had suggested Thanksgiving become a holiday, historians say.

In 1941 President Franklin Roosevelt established the current date for observance, the fourth Thursday of November.

Thanksgiving Turkey-in-Waiting

Each year at least two lucky turkeys avoid the dinner table, thanks to a presidential pardon—a longstanding Washington tradition of uncertain origin.

Since 1947, during the Truman Administration, the National Turkey Federation has presented two live turkeys—and a ready-to-eat turkey—to the President, federation spokesperson Sherrie Rosenblatt said in 2009.

"There are two birds," Rosenblatt explained, "the presidential turkey and the vice presidential turkey, which is an alternate, in case the presidential turkey is unable to perform its duties."

Those duties pretty much boil down to not biting the President during the photo opportunity with the press. In 2008 the vice presidential bird, "Pumpkin," stepped in for the appearance with President Bush after the presidential bird, "Pecan," had fallen ill the night before.

The lucky birds once shared a similar happy fate as Super Bowl-winning quarterbacks—a trip to Disneyland's Big Thunder Ranch in California, where they lived out their natural lives.

Since 2010, however, the birds have followed in the footsteps of the first President and taken up residence at George Washington's Mount Vernon Estate and Gardens.

After the holiday season, however, the two 40-pound (18-kilogram) toms won't be on public display. These fat, farm-fed birds aren't historically accurate, unlike the wild birds that still roam the Virginia estate.

Talking Turkey

Pilgrims had been familiar with turkeys before they landed in the Americas. That's because early European explorers of the New World had returned to Europe with turkeys in tow after encountering them at Native American settlements. Native Americans had domesticated the birds centuries before European contact.

A century later Ben Franklin famously made known his preference that the turkey, rather than the bald eagle, should be the official U.S. bird.

But Franklin might have been shocked when, by the 1930s, hunting had so decimated North American wild turkey populations that their numbers had dwindled to the tens of thousands, from a peak of at least tens of millions.

Today, thanks to reintroduction efforts and hunting regulations, wild turkeys are back. (Related: "Birder's Journal: Giving Thanks for Wild Turkey Sightings.")

Some seven million wild turkeys are thriving across the U.S., and many of them have adapted easily to the suburbs—their speed presumably an asset on ever encroaching roads.

Wild turkeys can run some 10 to 20 miles (16 to 32 kilometers) an hour and fly in bursts at 55 miles (89 kilometers) an hour. Domesticated turkeys can't fly at all.

On Thanksgiving, Pass the Pigskin

For many U.S. citizens, Thanksgiving without football is as unthinkable as the Fourth of July without fireworks.

NBC Radio broadcast the first national Thanksgiving Day game in 1934, when the Detroit Lions hosted the Chicago Bears.

Except for a respite during World War II, the Lions have played—usually badly—every Thanksgiving Day since. For the 2012 game, the 73rd, they take on the Houston Texans.

Macy's Thanksgiving Day Parade

For a festive few, even turkey takes a backseat to the Macy's Thanksgiving Day Parade in New York City, originally called the Macy's Christmas parade, because it kicked off the shopping season.

The tradition began in 1924, when employees recruited animals from the Central Park Zoo to march on Thanksgiving Day.

Helium-filled balloons made their debut in the parade in 1927 and, in the early years, were released above the city skyline with the promise of rewards for their finders.

The Macy's Thanksgiving Day Parade, first televised nationally in 1947, now draws some 44 million viewers—not counting the 3 million people who actually line the 2.5-mile (4-kilometer) Manhattan route.

Thanksgiving weekend also boasts the retail version of the Super Bowl—Black Friday, when massive sales and early opening times attract frugal shoppers.

A National Retail Federation survey projects that up to 147 million Americans will either brave the crowds to shop on 2012's Black Friday weekend or take advantage of online shopping sales, a slight dip from last year's 152 million shoppers.

Planes, Trains, and (Lots of) Automobiles

It may seem like everyone in the U.S. is on the road on Thanksgiving Day, keeping you from your turkey and stuffing.

That's not exactly true, but 43.6 million of about 314 million U.S. citizens will drive more than 50 miles (80 kilometers) from home for the 2012 holiday, according to the American Automobile Association. That's a small 300,000-person increase from last year.

An additional 3.14 million travelers will fly to their holiday destination and 1.3 million others will use buses, trains, or other modes of travel. These modestly rising Thanksgiving travel numbers continue to rebound slowly from a steep 25 percent drop precipitated by the onset of the 2008 recession.

Thanksgiving North of the Border

Cross-border travelers can celebrate Thanksgiving twice, because Canada celebrates its own Thanksgiving Day the second Monday in October.

As in the U.S., the event is sometimes linked to a historic feast with which it has no real ties—in this case explorer Martin Frobisher's 1578 ceremony, which gave thanks for his safe arrival in what is now New Brunswick.

Canada's Thanksgiving, established in 1879, was inspired by the U.S. holiday. Dates of observance have fluctuated—sometimes coinciding with the U.S. Thanksgiving or the Canadian veteran-appreciation holiday, Remembrance Day—and at least once Canada's Thanksgiving occurred as late as December.

But Canada's colder climate eventually led to the 1957 decision that formalized the October date.
