Great Pumpkin meteorite passes near Earth – Times

Ed. Print TRAVEL | The asteroid was baptized with that name by the coincidence with the feast of Ha-lloween. He went on to a slightly greater distance than is the moon and then continued.

Washington <- - end pub!> |

A large meteorite dubbed the “Great Pumpkin “because of its coincidence with the feast of Halloween, reached yesterday at its closest point to Earth, when he approached a just a little further away from the Moon, and then continue its journey through space.

“It’s close, very close! (…) It seems a skull rotating. It’s like the giant head of a white bear, “said astronomer Bob Berman, pointing to the images of stellar rock, relayed by Internet community” Slooh “which has an agreement with the Space Agency (NASA).

“The danger was not even there, it is gone. So in less than a minute, “said the astronomer.

The images broadcast live by the community” Slooh “portrayed a bright and fast space rock, the size of four football fields (400 meters in diameter ) that moved at a speed of 35 kilometers per second, which is a speed 29 times higher than that of a rifle bullet.

Those who could be with a small telescope could see a small bright spot , reflecting the moonlight and was traveling at a high speed.

The space rock, technically called 2015 TB145, was first sighted 21 days ago, on 10 October, telescopes University of Hawaii (USA) and, since then, NASA has monitored the trajectory of celestial object that never was a danger to Earth.

But on the night of witches, step an asteroid so large and so close to Earth has sparked debate in the scientific community, which considers crucial to know the structure of meteorites for how these stellar rocks can be destroyed, if they get too close to Earth.

“The probability that such a large meteorite hit the Earth is one in a million. (..) But, hey, if for example it is directed directly to the city of New York, the city would be completely destroyed. Although it is extremely unlikely, “said astrophysicist Mark Boslough.

Boslough, who works at Sandia National Laboratories in Albuquerque, New Mexico (USA), warned that if the” Great Pumpkin “had reached Earth would have produced a huge crater, destroyed trees and even caused an earthquake of 7.6 degrees on the Richter scale.

“If you hit the ocean could produce a tsunami. We do not know for sure. We are now studying how the energy of a meteorite could be transmitted to the water, “said astrophysicist.

In order to advance the research of these bodies, NASA scientists began Friday to launch waves Radio into the asteroid from the antennas of up to 34 meters long complex Goldstone, Calif.

The radio waves throwing antennas bounce off the asteroid and are collected by two NASA centers, located in West Virginia and Puerto Rico.

The last time he came was in 2006

According to initial calculations of NASA’s “Great Pumpkin” got close to 480,000 kilometers from Earth, equivalent to 1.3 times the distance between our planet from the moon.

last time an object of that size approached Earth was in July 2006, when the asteroid 2004 XP14 was able to approach 1.1 times the distance separating Earth from the Moon, according to the catalog NASA Near-Earth objects.

Until August 2027, the amateur astronomers can not see another asteroid to pass as close as “the Great Pumpkin.”

They will have to wait for 1999 AN10 rock that will come to nearly 384,400 kilometers, the same distance that separates our planet’s lunar satellite, according to NASA. In the coming days, the US space agency will provide images of the spatial phenomenon, shaped like a pumpkin for Halloween magic and continue to delight the curious space many days after it passes through the Earth.

Facebook spy WhatsApp your conversations – EntornoInteligente

Facebook spy your conversation WhatsApp / Journal Century / Vincent Steckler, Avast CEO, has not walked the bush at CeBIT INDIA 2015, an event that brings together many professionals to analyze the digital market being held the last week of October. And the leader of the popular computer security company said that Facebook spy WhatsApp our conversations to redirect advertising to each user. abc.es

Although many may surprise you this news, for Steckler this is not anything new. The social network Mark Zuckerberg and the popular instant messaging application do what Google has been doing for a long time.

“Google is an advertising company”, said Steckler, as recorded by the newspaper “Times of India”. “Their business model is very simple. Spy users to find out what interests them and serves them the ad That’s something that we all should know.” Has he declared

In fact, is a practice Google does not hide and that includes in the privacy that we all accept. “We collect information to provide better services to all our users from determining basic information such as the language you speak, to more complex data, such as ads that will be most useful, the people who matter most to you online or YouTube videos can LIKE “he explains Internet giant in its clauses. Therefore, nobody should be surprised.

And in the same line are placed Facebook and WhatsApp. Do not forget that Zuckerberg bought the messaging application in 2014 after several months of negotiations. “WhatsApp is a data collector to serve advertising within Facebook,” says the CEO of Avast. Therefore, if your conversations deal with some of your hobbies, it is no coincidence that this announcement has just appeared on your Facebook.

Steckler said, nevertheless, that represents a violation of privacy user data. He recalled: “To use WhatApp, each user has to share its database of contact with the platform, which means that they have already provided information about their friends Have you asked permission to your colleagues to do so.?”

The asteroid “Halloween” resembles a skull – El Universal

Radar images obtained from the Arecibo Observatory revealed that Asteroid 2015 TB145 has a size of 600 meters (1,968 feet), so that the space rock was found to be larger than the preliminary estimates.

Many have called this the “Halloween asteroid” because its closest to Earth step occurs on October 31. The most recent studies suggest that seems to be the core of an extinct comet or worn.

Scientists group of planetary sciences at Arecibo Radio Telescope found that the space rock, which will be spending 1.3 times the Earth-Moon distance, has an estimated turnover of 5 hours.

This asteroid also be seen in conjunction with other radio telescopes in the United States, including radar NASA’s Goldstone in California and radars “Green Bank “in Virginia. These comments will be used to determine even better shape, and surface rotation and refine the asteroid’s orbit. This in turn will allow better assessment of the dangers of a possible future impact. The Arecibo Observatory also observed the asteroid today, Halloween day.

The Asteroid 2015 TB145, discovered on October 10 by the Pan-STARRS I Survey Hawaii, was categorized as a potentially hazardous asteroid because of its size and proximity to Earth. “One of the responsibilities of the Arecibo Observatory is accurately measure the distance of asteroids and their velocities, which is then used to study the orbit and predict its movement for hundreds of years,” said Dr. Edgard Rivera-Valentin, a planetary scientist the Universities Space Research Association (USRA) in the Arecibo Observatory. Asteroid 2015 TB145 no danger nor will pass so close to Earth this century.

Valuable work in Arecibo

“Our measures also allow high-resolution images only surpassed by space missions sent to asteroids specifically. The difference is that our work is far more cost effective and can quantify a greater amount of asteroids, “said Dr. Patrick Taylor, USRA scientist at the Arecibo Observatory and leader.

The radar images obtained at the Arecibo Observatory suggest that the asteroid is moving in favor of clockwise, which is significant due to the movement of its brilliant features. “The bright and dark parts are an indicator of surface irregularities. For example, the dark central part could be a large circular depression, possibly Impact Crater said Dr. James Richardson, USRA scientist at the Arecibo Observatory.

The asteroid it has also been captured by telescopes ópticos.Efraín Morales, dela Caribbean Astronomical Society (SAC), captured a sequence of images showing the movement of the space rock in a span of 20 minutes. Look at the spectacular slideshow

The SAC said there are specific instructions to try to spot the asteroid 2015 TB145 on his website.

The Arecibo Observatory has observed about 80 asteroids in so far this year and will continue to monitor the sky to improve our understanding of potentially dangerous objects for Earth, as Asteroid 2015 TB145. The rotation of the space rock, as captured from the radio telescope at Arecibo, can be appreciated it by clicking on this link.

“On Friday night will be watching the passing space rock,” the SAC while stressing that those with telescopes can see the asteroid apparently looking like a star moving through the constellation Orion. The educational institution will be clarified on Friday night when he can be spotted with the help of telescopes, since during the close pass happens on Saturday as the asteroid would not be visible in the daytime sky.

Located in Puerto Rico, Arecibo Observatory radio telescope is home to one of the largest and most sensitive world dish. The Arecibo Observatory is operated by SRI International in partnership with the Ana G. Mendez University System and USRA Metropolitan University under a cooperative agreement with the NSF. Planetarium program is supported by the NASA program Near Earth Object Observation Program.

Today, a large asteroid will pass close to Earth. – Advertising Agency

An asteroid the size of four football fields will now very close to Earth, as confirmed by the European Space Agency (ESA). And while there is no danger for our planet, it is the demonstration that more efforts to locate potentially dangerous space rocks are needed.

The object, called 2015 TB145, is 400 meters long and will pass 480,000 kilometers from Earth. That is, to a greater distance that separates us from the moon. However, very rarely it happens so close to an object of this size and with sufficient mass to destroy an entire city if it fell in a populated area.

However, despite this time no danger exists, ESA emphasizes the fact that the asteroid was discovered on October 10, that is, only 21 days from the time of closest approach.

If his career had been slightly different, only we would have had the time to prepare for the impact.

Just 12 hours after the first sighting, which was held in Hawaii, the ESA confirmed the presence and trajectory of the asteroid from the observatory of Tenerife.

Although 480,000 km is a more than reasonable distance, on a cosmic scale corresponds to “a bullet whistled past his ear,” say the researchers.

Meteor “Great Pumpkin” closer to Earth – The Universal

A large meteorite, named the “Great Pumpkin” and the size of four football fields, will approach tomorrow during the feast of Halloween to Earth, where scientists from around the world prepare to witness an unusual phenomenon which only happens every ten years.

“It will seem a point of light. The human eye can not see and had better use a small telescope to view this celestial body so bright,” said Paul Chodas, director Center Near Earth Object Lab NASA JPL in Pasadena (California).

At 17:01 GMT on Saturday, the space rock, named 2015 TB145 technically, will approach 490 thousand kilometers from Earth, meaning that the meteorite will be at a slightly greater distance separating the Moon from our planet, according to the US Space Agency (NASA).

The TB145 has a diameter of about 400 meters and will pass near Earth orbit about 126,000 kilometers per hour without posing a threat to the planet.

“It’s a rare event. Asteroids of this size, so big, do not approach the Earth very often. I would say that happens every ten years or so once, “said astronomer Chodas.

According to the catalog of the NASA Near-Earth objects,” Great Pumpkin “will be the object closer pass our planet until at least August 2027, when it is expected that the rock 1999 AN10 approaching almost 384,400 kilometers, the same distance that separates our planet from the moon.

According to the astronomer, Over asteroid “Great Pumpkin” near Earth is more than a threat, an opportunity to enjoy with children in Halloween and investigate this type of celestial bodies.

Scientists at the US agency began today to use antennas up to 34 meters long Goldstone complex in California, to launch against the asteroid radio waves that bounce off the surface and be collected by two NASA centers, located in West Virginia and Puerto Rico.

These two centers are responsible for collecting the waves and molded images of stellar rock, NASA expects to process with a resolution of up to two meters per pixel.

“This does not It is the first time we used radar to see the image of an asteroid. But, possibly, this will be one of the times you’ll have a better picture because rarely an asteroid has passed so close to Earth. Tomorrow we will see strong and clear, “Chodas said.

Knowing the structure, surface, composition and evolution of the” Great Pumpkin “will allow scientists to learn more about how these stellar rocks work and how they can be destroyed.

“It’s good to know more about these bodies should you ever have to divert an asteroid on Earth. This poses no danger, but may one day need to deflect an asteroid and it is important to know as much as we can on the physical characteristics of these bodies, “defended Chodas.

The celestial body was discovered on 10 October for a telescope in Hawaii (EU) and since then there have been calculations to pinpoint its orbit.

The NASA scientists have warned that the gravitational influence of the asteroid will have no detectable effect on Earth as tides and movements of tectonic plates.

The best place to keep track of the “Great Pumpkin” will be Europe and Asia because when celestial rock approach in these continents it’ll be dark and the rapid career bright meteor can best be seen, said the astronomer.

NASA detects and usually tracks asteroids and comets passing close to Earth using ground and space telescopes with its “Watching Near Earth, “which it called” Spaceguard, “to detect if any could be potentially hazardous to the planet objects.

The ‘Great Pumpkin’: the asteroid that will visit Earth Halloween – Semana.com

Halloween is coming. And with the arrival of this celebration in which children dress up as dead, witches and ghosts trick or treating, the visit of “the Great Pumpkin” approaches.

It is not, however, a character in this pagan festival of Celtic origin: a giant asteroid is technically known as TB145, this object has an estimated 400 meters wide

This makes it 20 times bigger than the meteorite that streaked and. He exploded in the sky over Chelyabinsk, Russia, in 2013, destroying hundreds of windows and leaving more than a thousand injured because of the debris

And his speed is also higher. while Russian meteorite entered the atmosphere at a speed of 19 kilometers per second, the “Great Pumpkin” moving at 35 km / s.

But fortunately, pass at a distance that though close in spatial terms, are considered safe for our planet.

Opportunity

Indeed, when it is at its closest point to the TB145 is 480,000 km from Earth. That is, 1.3 times the distance between the Moon and Earth.

And it will not be easily visible. “It will take at least a small telescope to see it,” said Paul Chodas, director of the Center for the study of the Near Earth Object of the Jet Propulsion Laboratory of NASA.

For the space agency American, however, this is a wonderful opportunity to study the asteroid, because the next time such a large object pass close to Earth will be only in August 2027.

NASA plans to image radar to analyze the surface of the object, but also to detect whether or not it is accompanied by a moon, which may provide clues about its mass and density.

“The gravitational influence of the TB145 is so small you will not have detectable effects on the Moon, or tectonic plates of the Earth tides, “NASA said in a statement.

catastrophic consequences

Fortunately, the “Great Pumpkin” will briefly crossing the sky orbit. But if Earth had been brought on its way, there had been no time to react.

“An asteroid of this size is very hard to save it with a warning of only 20 days,” he told Chodas Popular Science magazine.

If collided with Earth, a piece of rock and ice as the TB145 could cause catastrophic devastation, the researcher added.

Currently, scientists are working on plans to deflect and destroy asteroids as our planet is hit middle asteroids near de100.000 years each.

But for now, NASA says we do not have to worry about.

Scientists successfully prove more durable lithium battery – ABC Color

WASHINGTON. Scientists at Cambridge University have successfully tested a model of lithium battery that brings that technology to a longer useful life and could facilitate the electric car has as much autonomy as gasoline.

The experiment, whose findings published in the journal Science today, small-scale test the feasibility of a combination battery of lithium-oxygen, which opens the door to theoretical production of lithium batteries have limited capacity to load.

At present, the capacity of lithium batteries is limited by the formation of lithium peroxide during discharge efficiency blocking irremediably battery by blocking the micropores of the anode receiver, typically carbon.

The design of this battery includes a lithium metal negative electrode, a nonaqueous electrolyte and a positive electrode, that by adding lithium hydroxide instead of peroxide and graphene electrodes with larger pores that prevent the barrier presents current batteries.

The researchers hope that the findings of his study to accelerate mass production of batteries Lithium-oxygen more efficient, more burden on both electric cars to electronics.

The battery capacity of conventional lithium ion around 80% of rated capacity, while proved by researchers at the University of Cambridge can exceed 93%. In addition, new experimental batteries can be recharged more than 2,000 times and are more resistant to water, one of the problems of current batteries.

The lithium-oxygen batteries have a higher capacity relative the space occupied and could finally make electric cars have the autonomy of a gas tank, something that would revolutionize a clean technology that gradually becomes more popular,

However, the scientists, led by professor of chemistry at Cambridge material Clare Grey , remember that the experiment is provisional and there are many obstacles to reach a phase of industrial production.

The lithium batteries Oxygen developed so far are more unstable and inefficient in the long run, something that has prevented its expansion as an alternative.

Puebla tuned observatory to monitor TB145 asteroid 2015 – XEU

On 31 October 2015 TB145 asteroid will pass at a distance of about 525,000 kilometers of our planet, equivalent to 1.3 times the average distance from Earth to the Moon, so tuned instruments for INAOE observe.

If the weather permits, will be closely monitored by a team of astrophysicists INAOE located in Tonantzintla, Puebla, said researcher Jose Ramon Valdes.

This, as part of a monitoring program asteroid that initiated the National Institute of Astrophysics, Optics and Electronics (INAOE), public research center of the National Center for Science and Technology (CONACYT).

INAOE renewed, for this and other projects, the Schmidt House, the historic telescope with which thousands of astronomical discoveries in the decades of the forties and nineties of the twentieth century were made.

José Ramón Valdés, INAOE researcher said that the size of this asteroid has been estimated between 280 and 620 meters and is the closer of a large asteroid from July 3, 2006, when the asteroid 2004 XP14 spent 1.1 times distance to the moon.

“Although the approach of a large asteroid is not very common, asteroids middle step is much more common, it is estimated that the number of asteroids between one hundred meters and one kilometer near-Earth is about 19 000 500 and most of these cosmic rocks they have not yet been discovered.

He noted that the number of small asteroids, under a hundred meters, is much higher, hence the scientific importance and from the point of view of security of the planet, with search systems and monitoring of asteroids, in particular those They are known as Near Earth Objects and even more so-called potentially hazardous asteroids.

“The latter can it have a minimum distance of orbital intersection with Earth less than 750 000 kilometers. An asteroid medium definitely has the ability to destroy a metropolitan area should it fall in the right place,” he said.

The asteroid was discovered TB145 2015 barely 10 October by the Pan-STARRS1 telescope, operated by the Institute of Astronomy, University of Hawaii, one of the systems in the world dedicated to the search for new asteroids.

“To date just over 13 thousand near-Earth and in the year 215 thousand have been discovered new objects of this type asteroids are known. As important is to discover an asteroid to develop systematic monitoring campaigns once they are discovered.

Having a greater number of observations of a particular asteroid to calculate more precise orbital elements and determine with greater certainty the possible danger to impact on the surface of the Earth, “said the researcher.

With the aim of increasing the number of observations of asteroids near the Earth has created an international monitoring network in more than 40 countries.

“In order to insert Mexico in this important task, coordinating Astrophysics INAOE we took on the task of renovating the historic Schmidt Chamber of Tonantzintla was inaugurated in February 1942″, notified astrophysicist.

The reactivation of the Schmidt camera consisted of placing about 77.4 cm mirror telescope a new aluminum layer as reflective surface.

It also called cleaning the 66.04 correcting lens used to correct spherical aberration produced by the mirror.

They put together new telescope control systems and imaging, as light pollution conditions in Tonantzintla prevented still use astronomical plates operating in the Chamber since its inauguration Schmidt said.

Once the trial period ended renewed Schmidt Chamber have found that improvements have resulted in a substantial increase of the benefits of this historic telescope.

“On the one hand, it allows us to overcome light pollution, since the integration times of our images are substantially lower and, secondly, have allowed us to obtain images of very faint asteroids whose flows could not be detected before the restoration process .

Under current conditions we can observe asteroids that are 32 times weaker than previously discovered, “Valdes said.

The researcher added that for INAOE is a great satisfaction that the Schmidt camera is reinserted in modern astronomical observations.

He said he can be dedicated full time permanent observation campaigns of near-Earth asteroids, potentially hazardous asteroids and those who, in the not too distant future, could be targets for future NASA missions.

“The comments we will also allow us to know some important physical parameters of asteroids such as its period of rotation, shape and size, and the tilt of its axis of rotation,” he said.

Knowing these physical parameters is very important because if they find that any of these objects can collide with Earth in the future will depend on how much damage, if it is larger, more massive and faster is potentially more dangerous one smaller, less massive and slower.

Create a device to “see” through walls – Clarín.com

Researchers at the Massachusetts Institute of Technology (known as MIT, for its initials in English) developed the RF-Capture device, which can “see” images of the human body and identify a person behind a wall.
The device, which will be marketed in about a year, can distinguish one person from another and even track the movement of the human hand to simulate writing in air, without the need for sensors in the body or cameras in the halls, the site reported Quartz
RF-Capture works by emitting radio signals low power can pass through a wall and bounce in the body that is the other side.; then the images are captured by the device, which combines information from multiple reflections to join the silhouette of the person.
The researchers propose that the technology can be made available for applications ranging from video games and movies to hotlines and eldercare. Today to capture movements in the film industry, for example, the actors should wear sensors and move in a room full of cameras; but the new device could track their movements, even if they are behind objects or walls.
In the case of a smart home, RF-Capture could help adjusting the heating and lighting as there are people in the room.
According to the site News MIT researchers have incorporated the technology as part of a product called Emerald, specifically designed to detect, predict and prevent falls in older people. The product was presented to the President of the United States, Barack Obama, in August during Demo Day, an innovation forum taking place in the White House.
The researchers noted that there are uses “unwanted” that could lend new product: thieves could know if a house is occupied or not.
“We want to ensure that people will not use it for evil reasons,” the site Gizmodo a researcher at MIT, Dina Katabi.
“We are working on two fronts: first designing blockers that can prevent someone from being tracked except for your own device or with its consent; and, secondly, we need to have regulations that dictate how and when the devices can be used. Privacy is always a priority, “he said.

Fossils are common ancestor of apes and humans | Peru Trade – Trade

A new primate, they have called Pliobates Cataloniae, it has been discovered by researchers from the Catalan Institute of Palaeontology Miquel Crusafont. According to experts, could have been the last common ancestor between gibbons (lesser apes biped family of hilobátidos ) and great apes human .

Salvador Moya-Sola, director of this institution, said that the discovery was made from a skeleton of 11.6 million years found in the paleontological site Can Mata (Spain).

The remains of this new primate (70 bones of the skull, leg and left arm) corresponding to an adult female to paleontologists have named Laia, weighing about 4 or 5 kilos, fed soft fruits and hung in the tops of the trees.

The skull Pliobates Cataloniae has been reconstructed virtually with high resolution scanners and, thanks to the remains of the extremities, has been Laia has some primitive features, such as the anatomy of the arm, the joint between the humerus and radius, and the bones of the wrist.

The work of this team, published in the journal “Science”, radically changes the hitherto accepted model on hilobátidos and ancestor of hominids, and provide very strong clues to the origin of gibbons current.

According to Moya-Sola said the origin of gibbons is a mystery about the lack of fossil record, but until now most scientists thought their last common ancestor with hominids should be of great size, about 40 kilos.

David Laia Alba said that might have been the last common ancestor of all the large and small anthropomorphic and human .

Laia is noted that the species 17 million years ago did they separated the one hand gibbons, and other hominid and ape is the first small form present in the existing hominids, which has important implications for reconstruct the last common ancestor of both groups

New primate could last link between gibbons and humans – The Universal

A new primate , who have called Pliobates Cataloniae , discovered by researchers at the Catalan Institute of Paleontology Miquel Crusafont, might have been the last common ancestor between gibbons, and great apes and humans.

The director of the Institut, Salvador Moya-Sola, and principal investigator of the study, David Alba, highlighted by presenting the finding that the discovery was made from a skeleton 11.6 million years found in the paleontological site of Can Mata (northeastern Spain), the most important fossil primates the middle Miocene Eurasian continent.

The remains of this new primate, 70 bones of the skull and other leg and left arm, corresponding to an adult female to paleontologists have dubbed “ Laia “, weighing about 4 to 5 kilos, fed soft fruits and climbed and hung in the tops of the trees.

The skull Pliobates Cataloniae has been reconstructed virtually high resolution scanners and the remains of the extremities it has been seen that Laia has some primitive features , as the anatomy of the arm, the joint between the humerus and radius, and the bones of the wrist, having the basic design of current hominoids.

The work of this team, published in Science , radically changes the hitherto accepted model on hilobátidos and ancestor of hominids, and provide very strong clues to the origin current gibbons.

David Laia Alba said that might have been the last common ancestor of all apes and big and small human, within the group of primates, and is characterized by having no external tail.

Laia is noted that the species 17 million years ago did they separated the one hand gibbons (hilobátidos ), and on the other hominids (great apes and humans), and is the first ape small form present in existing hominids, which has important implications to reconstruct the last common ancestor of both groups.

According to Alba, current hominoids are a group of primates that includes the small apes (gibbons and siamangs, which constitute the family of the hilobátidos) and great apes (orangutans, gorillas and chimpanzees) that human form the family of hominids.

All current hominoids share the absence of external queue, a orthograde body design that enables them to an upright position of the trunk, and several cranial features.
