    Mini-robot finds surprise in Mexico's ancient Temple of Quetzalcoatl

    Researchers lowered a robot with a camera into a tunnel under Mexico's Teotihuacan and have discovered three ancient chambers under the pyramid. NBCNews.com's Dara Brown reports.

    A diminutive robot helped researchers make a substantial discovery during preliminary tests conducted in a tunnel running under the Temple of Quetzalcoatl at the archaeological site of Teotihuacan, the team said Monday.

    The team expected to find only one chamber in the last section of the tunnel — but instead, they found three, team leader Sergio Gomez said in a report published by the Mexican newspaper El Universal. The chambers are thought to have been used by Teotihuacan's rulers roughly 2,000 years ago for royal ceremonies or burials, but they're so choked with mud and rubble that they haven't been explored in modern times.

    A worker from the National Institute of Anthropology and History walks next to a robot used to explore ruins at the entrance of a tunnel in the archaeological area of the Quetzalcoatl Temple, near the Pyramid of the Sun at the Teotihuacan archaeological site.

    That's where the 3-foot-long (1-meter-long) robot known as Tlaloc II-TC comes in: The robot is designed to drive through the tight spaces leading to the back of the tunnel beneath the Temple of Quetzalcoatl, also known as the Temple of the Feathered Serpent. It's equipped with a video camera as well as mechanical arms to clear obstacles.

    The current project follows up on an earlier round of robotic exploration by Tlaloc II-TC's predecessor, Tlaloc I, in 2010. (Tlaloc was the Aztec god of rain.)

    In 2010, Gomez said there was a "high possibility that in this place, in the central chamber, we can find the remains of those who ruled Teotihuacan." The city was once an influential center of Mesoamerican culture, but little is known about its rulers. Archaeologists have not yet found any depictions of a ruler, or any tomb of a monarch.

    El Universal quoted Gomez as saying that the configuration of the space beneath the temple appears to be similar to that of the tunnel running beneath Teotihuacan's Pyramid of the Sun, where four chambers were explored in the 1970s. About 76 meters (250 feet) of the Quetzalcoatl tunnel have already been uncovered, leaving 30 meters (100 feet) or so in the last section. After a round of robotic reconnaissance, archaeologists intend to clear out that section for exploration.

A remote-controlled robot has relayed back video images of what appears to be three ancient chambers beneath the temple.

    No gloom or doom as crowds usher in new age at Maya monument

    Victor Ruiz Garcia / Reuters

    A tourist raises her hands during a group meditation ceremony near the pyramid of Kukulkan at the Chichen Itza archaeological site on Dec. 21. Hundreds gathered to greet the sunrise on a day that marked a new age on the Maya calendar.

    Tourists, mystics and Maya priests accentuated the positive this morning at Mexico's best-known Maya monument, the El Castillo pyramid at Chichen Itza, on a day that some thought would bring catastrophe.

    For years, doomsayers warned that the end of a grand 5,125-year cycle in the Maya timekeeping system would signify the end of the world as well. Some feared that Dec. 21 would be marked by solar blasts, earthquakes, superstorms or other planetary disruptions. But the hundreds who flocked to El Castillo took a different message to heart.

    "It's not the end of the world, it's an awakening of consciousness and good and love and spirituality — and it's been happening for a while," Mary Lou Anderson, a 53-year-old information technology consultant from Las Vegas, told Reuters.


    Reuters reported that the rituals at Chichen Itza began just before the winter solstice, as dawn was breaking. A spotlight illuminated the western flank of El Castillo, a 100-foot-high pyramid that was built sometime between the 9th and the 12th centuries to serve as a temple to the Maya serpent god Kukulkan. Then a group of five English-speaking tourists, dressed in white,  made their way across the plain, dropped their bags and faced the pyramid with their arms raised.

    As the sun climbed into the sky, a man with dreadlocks played a didgeridoo at the north end of the pyramid, while a group of tourists meditated on brightly colored mats.

    The visitors said they came to Chichen Itza not to face the world's end, but to make a new beginning. "I hope something happens to make me a better person," said Graham Hohlfelde, a 21-year-old student from St. Louis, Mo. "If I can get a little cosmic help, I won't turn it down."

    Gee, the only apocalypse that did occur today happened in the programming offices of the History Channel, Discovery Channel, NATGEO, SYFY, etc. Now what are they going to do with the countless hours of doomsday prophecy programming? They obviously cannot show these programs again.

    New, doom-free era begins for Maya

    Guatemalan Mayan natives take part in celebrations marking the end of the Maya age at the Tikal archaeological site on Friday.

    By Alan Boyle, Science Editor, NBC News

    Follow @b0yle


    The sun has arisen today at Maya monuments in Mexico and Guatemala, heralding the completion of a 144,000-day calendar cycle — but not the end of the world.

    Most archaeologists say the ancient Maya regarded sunrise as the signal for the turnover, much as we regard midnight on New Year's Eve as the time to party. And sure enough, tourists as well as modern-day Maya in traditional garb gathered at Chichen Itza's El Castillo pyramid in Mexico to greet the day. Josh Gates, host of the Syfy TV show "Destination Truth," is live-tweeting the activities. (Syfy is owned by NBC Universal, which also owns NBC News Digital.)


    The ancient Maya calendar marks Dec. 21 as the end of a cycle known as a baktun, which lasts 144,000 days or nearly 400 years. This finishes up the 13th baktun since Year Zero for the Maya, and taken together, all that time represents an even longer 5,125-year cycle of creation. That led to speculation that the Maya expected the gods to reset the cosmos on Dec. 21. Somehow that speculation was taken seriously enough to whip up this whole end-of-the-world hype.

    Along the way, all sorts of claims were made about unseen planets, solar disturbances and other supposed earth changes that would make today a very bad day. But judging from the pictures coming from Chichen Itza and other Maya monuments, people are having a good time today.

    In the longer term, Maya community leaders hope all the attention they're getting this week will translate into a wider awareness of their ancient culture and their modern-day challenges. They're not worried about doomsday; they're worried about poverty. Check out this PhotoBlog posting for more about the real concerns being voiced by the indigenous people of Guatemala.

    The Maya calendar's Big Day dawns ... with no doomsday in sight

    Dec. 21 is the day many believe the ancient Maya predicted the world would end. The hype has spread on social media, illustrating the world's fascination with the end of time. NBC's Kristen Dahlgren reports.

    By Alan Boyle, Science Editor, NBC News

    After years of claptrap about the Maya apocalypse on 12/21/12, the Big Day has dawned in many parts of the world. It's daytime in China, one of the world's hot spots for doomsday angst. So far, no solar flares have fried the earth, and no mountains have fallen into the sea. The sun will soon rise on Mexico's ancient Maya monuments, where thousands are gathering to greet a new era.

    Then what?

    "I don't think there's going to be a herd of jaguars descending from the heavens," said John Henderson, an anthropologist at Cornell University who specializes in the Maya world.

    Archaeologists and astronomers have thoroughly debunked everything about the doomsday myth: The Maya never expected that the world would end when their Long Count calendar rolled over to the next 144,000-day cycle in 2012. Earth's magnetic field is not going haywire. There's no threat from the Large Hadron Collider, or the sun, or unseen planets, or the galactic plane.


    More: Keep up to date on non-doomsday

    Not everything about the Big Day is doom and gloom: Tourists and New Age types have flocked to the Maya ruins of Chichen Itza to greet Friday's dawn and the start of a new age with rituals old and new. "There is an explosion of consciousness through this," a gray-haired Californian musician named Shambala Songstar told Reuters. "We are becoming billionaires of energy. Opening to receive more light and more joy."

    Minu Nair, a 27-year-old tourist from India, joked about the doomsday connection after hiking up to the top of the Maya pyramid at Coba, about an hour's drive from Chichen Itza. "At least we can die saying we saw the end of the world," he said with a laugh.

    But not everything is sweetness and light, either. "We have to beware of mass psychosis," said Mexico's best-known soothsayer, Antonio Vazquez Alba. According to The Associated Press, Vazquez warned his followers to stay away from mass gatherings on Friday, out of concern about stampedes — or even mass suicides "of the kind we’ve seen before."

    Guatemalan shaman Christian Nottbohn conducts a Maya ceremony in Rastrajon, which was once a settlement for warriors tasked with protecting the ancient city of Copan in present-day Honduras.

    Elsewhere, more than 1,000 members of Church of Almighty God were reportedly detained in China for spreading doomsday rumors. Hundreds more were heading for Serbia's Mount Rtanj and the French town of Bugarach, in search of a haven from the apocalypse. Authorities in Argentina limited access to a mountain called Cerro Uritorco after rumors spread about a plan for "massive spiritual suicide." In Michigan, dozens of schools were shut down early, partly because of end-of-the-world worries stoked by the Maya hype.

    More: Rumors lead to school closures in Michigan

    What would the ancient Maya think? "The Maya thought about everything in terms of cycles," Henderson told NBC News today. "Some may have expected the gods to fine-tune their creation of humanity. But others may have taken it more as an occasion to contemplate whether they were the kind of people they ought to be. And we can take it in the same way."

    Think of it as the opportunity for New Year's Resolutions — or, in this case, New Baktun's Resolutions.

    The Maya Long Count calendar divides time into a series of periods, building up to a cycle called the baktun that lasts 144,000 days, or a little more than 394 years. Dec. 21 marks the completion of 13 baktuns, which the Maya saw as a full cycle of creation. In some texts, the end of the 13th baktun — 13.0.0.0.0, in numerical notation — was used to refer to a long, long time.

    "It would be like you and I saying, 'George Washington was such a great leader for us that we'll still be talking about him in the year 3000,'" said Walter Witschey, an anthropologist and Maya expert at Longwood University in Virginia.

    But the Maya never thought time stopped in 2012 — or the year 3000, for that matter. A recently discovered Maya workshop demonstrated that calendar-makers contemplated time frames well beyond 2012, and the longest Maya calendar cycle, the alautun, goes out about 63 million years.

    More: How the Maya calendar works

    The concept of a Maya apocalypse appears to date to the 1960s: That was when anthropologist Michael Coe wrote a book speculating that the Maya saw the final day of the 13th baktun as the time for an "Armageddon" that would overtake all creation. Over the years, that idea became wrapped up with Christian ideas about the end times.

    "So much of this Maya calendar fascination plays to very natural human tendencies to look for sources of information about the future, right?" said Loa Traxler, an archaeologist who is the curator of a "Maya 2012" exhibit at the Penn Museum in Philadelphia. "When you add to that a lot of opinions that would point us to the end of days, and events of great reckoning, and destruction as the opening chapter of great change ... those are trends that play very strongly in modern society."

    Some cultures get more concerned about it than others. In May, an international public opinion survey conducted by Ipsos for Reuters found that 20 percent of the Chinese respondents agreed that the Maya calendar would mark the end of the world. About 12 percent of the U.S. respondents felt that way, compared with only 4 percent in Germany.

    Traxler said she encountered several well-educated people who asked her serious questions about the 2012 Maya apocalypse during a cruise through the Mediterranean in 2009. "It caught me by surprise," she said.

    Her experience on that cruise was one of the reasons why she went to work on the "Maya 2012" exhibit, which tells the full story about the ancient Maya and their attentiveness to the cycles of time. "It has been quite an amazing adventure over the last several months," she said. "People have decided to make hay out of this."

    More: In Maya doomsday, marketers see $$$

    Dec. 21 has arrived, and predictions about the end of the world have proven false. TODAY's Jenna Wolfe asks people who believed the prophecy how they plan to move forward, now that we're all still here.

    So when exactly does it stop? The consensus view among archaeologists is that the 13th baktun will end, and the 14th will begin, at sunrise Friday. "That would be sunrise in the Maya world, not in Beijing," Henderson joked.

    But Witschey said there's still a bit of uncertainty about how the dates are calculated. "Most scholars would agree that we have a match within about three or four days," he said. "That means that the rollover of cycle 13 is going to hit on Dec. 21, or 23, or 24."

    If past doomsday scares are any guide, it will take a while for the folks who were so worried about 12/21/12 to settle down. Some might claim that the date for the apocalypse was miscalculated, and will actually come at a later time. Others might say that the world-shifting change has actually begun, but the rest of us just can't sense it yet. Case studies abound, ranging from the Great Disappointment of 1844 to the Planet Clarion prophecy of 1954 to the Rapture of 2011.

    The precise day or hour of the Maya calendar turnover doesn't matter all that much to Witschey.

    "It's no big deal," he said. "Whatever day it is, I'm going to wake up the next day, going forward."

    That sounds sensible to me. How's it sound to you? Even though it's no big deal, we'll be passing along updates during the Big Day and beyond. Just check in with http://cosmiclog.nbcnews.com/2012 for the latest.

    Update for 11:15 p.m. ET: NASA says it has been fielding hundreds of questions a day from people who are worried about 12/21/12. "We have done all we can to answer questions from the public," David Morrison, an astrobiologist at NASA's Ames Research Center, told NBC News in an email. "Unfortunately, many don't believe us, like several mothers who have written to me in the last few hours asking if they should keep their children at home today."

    Morrison forwarded one email message (with the sender's name removed) that he said was typical. Here's what it said: "Just like to know how I can survive the end of the world? Two friends of mine committed suicide this week because of that dreaded day, date. I just want to try to survive, and please tell me what to do!?"

    It's impossible to verify the substance of that particular email, but if the sentiment is "typical," I'm hoping such folks are getting the reassurance they need. DON'T PANIC!

    Google maps ancient Mexican ruins

    INAH

    Children watch as a rider drives a camera-equipped tricycle around a temple at the Chichen Itza archaeological site in the Mexico's Yucatan state. Imagery from the tricycle trip has been incorporated into Google Street View.

    Google is expanding its Street View offerings to include dozens of 360-degree photo tours of ancient Mexican monuments such as Teotihuacan, Chichen Itza and Palenque.

    The additions are aimed at helping Mexico "open a window to the world, to encourage physical visits to the pre-Hispanic sites and thus in turn benefit cultural tourism," Miguel Angel Alva, director of marketing for Google Mexico, said this week in an announcement from Mexico's National Institute of Anthropology and History, or INAH.


    Follow @CosmicLog

    Google collected the all-around views by having riders pedal camera-equipped tricycles around the Mexican sites, with INAH's cooperation. INAH said the photo project started two years ago. Thirty sites have been added to Google Street View so far, with the aim of having more than 80 sites online by the end of the year. Eventually, all 189 of the archaeological sites under INAH's custody will be cataloged, the institute said.

    The virtual tours highlight some of Mexico's best-known monuments:

    • Chichen Itza's El Castillo, also known as the Temple of Kukulkan, a Maya pyramid built more than a millennium ago. Some researchers say the temple's staircase was designed to create a "feathered serpent" shadow during the spring and autumn equinoxes, and can also produce quetzal-bird echoes when you clap your hands at just the right spot.
    • Teotihuacan, the monumental city that was founded by a mysterious pre-Aztec culture and reached its height somewhere between 100 B.C. and the year 750.
    • Tulum, a Maya walled city on the Yucatan Peninsula's Caribbean coast that dates back to the 13th century and was still occupied when the Spanish arrived in the early 16th century. Today the well-preserved ruins are the middle of a modern-day resort area.
    • Palenque, an important Maya site in the Mexican state of Chiapas that reached its peak in the 7th century. Last year, the remote-controlled exploration of a 1,500-year-old tomb at the Palenque site made headlines. 
    • Uxmal, a city that flourished during the Classic Maya period and is now a popular tourist attraction. Among its best-known ruins are the Pyramid of the Magician and the Governor's Palace.

    Micro-camera explores Maya tomb

    INAH

    Blood-red paint clings to the walls of a 1,500-year-old tomb chamber hidden within a Maya pyramid in Mexico.

    By Alan Boyle, Science Editor, NBC News

    A tiny remote-controlled camera is providing remarkable views of an apparently intact 1,500-year-old Maya tomb that's thought to hold a ruler's remains.

    The 2-inch-long camera was lowered into a vault inside a pyramid at the Palenque archaeological site, in the hills of the southern Mexican state of Chiapas. Archaeologists have known about the vault since 1999, but the only access to the room was through a small shaft in the pyramid — just big enough to fit the micro-camera through.


    The images reveal a series of nine figures painted on the walls in black on a vivid, blood-red background. Dishes, apparently meant to hold funerary offerings, are set on the floor. The camera also spotted pieces of a funerary shroud made of jade and mother of pearl. "The characteristics of the funeral site show that the bones could belong to a sacred ruler from Palenque, probably one of the founders of a dynasty," Reuters quoted archaeologist Martha Cuevas as saying.

    The tomb is hidden within a pyramid known as Templo XX at Mexico's Palenque archaeological site.

    Workers had to climb down a ladder to get to the place where the micro-camera could be lowered through a small shaft.

    OK, I see where this is going ... "Indiana Jones and the Tomb of Blood." I'd watch that movie.

    A satellite view from GeoEye shows the 1,000-year-old Maya monuments at Chichen Itza on Mexico's Yucatan Peninsula.

    Holiday calendar: Stairways to heaven

    By Alan Boyle, Science Editor, NBC News

    This satellite image from GeoEye highlights the Maya pyramid known as El Castillo, or the Kukulkan Pyramid, the focal point of a monumental plaza at Chichen Itza on Mexico's Yucatan Peninsula. The pyramid was apparently constructed with an eye to the calendar: During the spring and autumnal equinoxes, patterns of sunlight move across the main stairway to make it look as if the body of a serpent (Kukulkan) is creeping downward to join up with a giant serpent's head carved in stone at the bottom.

    Each of the stairways has 91 steps, and when you add the platform at the top, the total comes to 365 steps — the number of days in a year. The Maya, of course, were expert calendar makers. The fact that their "long count" calendar comes to an end in 2012 has led some to fear that the world will end. But even present-day Maya say that's silly. It's merely the end of a cycle, just as we'll be ending a calendrical cycle in just a couple of weeks.

    This view of Chichen Itza represents today's offering for the Cosmic Log Space Advent Calendar, which presents daily images of Earth from space through Christmas Day. For a wider perspective on Chichen Itza, check out this Ikonos satellite image. (Can you spot the swimming pools and the baseball diamond in the full-resolution image?)

    How on earth could they have understood equinoxes, shadow patterns and architecture well enough not just to come up with an idea like that, but to actually build a giant structure that pulls it off? It really boggles the mind.
