Shaped asteroid “Skull” pass close to Earth today – El Diario de Yucatan

         

     

Culiacan (Notimex) .- The 2015 TB145 asteroid will pass close to Earth on Saturday, a distance slightly greater than that between the Earth and the Moon, said Tatiana Kokina Yurova, a researcher at the Autonomous University of Sinaloa (UAS).

The head of the Center for Astronomy of the UAS said that the asteroid poses no threat to Earth, but the National Administration of Aeronautics and Space Administration (NASA) is monitoring its orbit because it moves at a speed of 126,000 kilometers per hour.

With a diameter of about 400 meters, 2015 TB145 will pass about 490,000 kilometers from Earth, equivalent to 1.3 times the distance to the moon, and it will take at least a small telescope to view it.

“The gravitational influence of the asteroid is so small you will not have detectable effects on the Moon, or tectonic plates of the Earth tides” said the researcher from the School of Earth Sciences and Space (facite) of the UAS.

The asteroid was discovered on October 10 by a telescope in Hawaii and since then there have been calculations pinpoint its orbit.

Tatiana Kokina Yurova noted that over TB145, rather than a threat, an opportunity to investigate this type of space bodies, since it is the largest asteroid ever found in past 30 years.

He stressed that radioantenas complex Goldstone, in California, will be reoriented to monitor and study over TB145.

He noted that the asteroid is moving at a speed unusually high, according to NASA.

“Great Pumpkin” round Earth orbit – The Universal

A large meteorite dubbed the “Great Pumpkin” because of its coincidence with the feast of Halloween, reached today at 17:01 GMT its closest point to Earth, when he approached a just a little more distance the Moon, and then continue its journey through space.

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

“The danger that even was there is gone. So within a few minutes, “he said the astronomer.

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

Those who could get hold of 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, October 10, by telescopes of the University of Hawaii (USA) and, since then, NASA has monitored the trajectory of celestial object that never was a danger to Earth.

But, the night of witches, the passage of an asteroid as big and as 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 come Earth too.

“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 and is responsible for collecting waves and shaping images of the rock star, the space agency expects to process with a resolution of up to two meters per pixel.

According to initial calculations 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.

The last time an object of similar size approached Earth was in July 2006, when the asteroid 2004 XP14 was able to approach 1.1 times the distance separating the Earth from the moon, according to NASA catalog on nearby objects Earth.

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

They will have to wait until the Rock 1999 AN10 which will approach almost 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 with pumpkin shape by the magic of Halloween and continue to delight the curious space many days after his time on earth, only one stop of his journey through the vastness of space.

Tonight a large meteorite rub Earth – El Universal (Venezuela)

Washington .- 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 that only happens every ten years.

“It may 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,” he said today Efe Paul Chodas, director of the Center for Near Earth Objects Laboratory NASA JPL in Pasadena (California).

At 17.01 GMT on Saturday, the space rock, named 2015 TB145 technically, It will approach 490,000 kilometers from Earth, meaning that the meteorite will be at a slightly greater distance separating the Moon from our planet, according to the 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 (USA) 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 or tectonic plate movements.

The best place to keep track of the “Great Pumpkin” will be Europe and Asia because when approach the celestial rock in these continents and it will be dark and fast race 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 their program “Observation of Near Earth Objects”, which called “Spaceguard,” to detect if any could be potentially hazardous to the planet. EFE

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.

Spanish astronomer says that the “Great Pumpkin” shows our vulnerability – Terra Peru

The fact that until two weeks ago did not knew the existence of the asteroid 2015 TB145, known as the “Great Pumpkin” and now will pass near Earth, shows that “we are very vulnerable,” said one of the astronomers Spaniards involved in monitoring.

For the astronomer Miquel Serra, a member of the research group of the Solar System Astrophysics Institute of the Canary Islands (IAC), it is “incredible” that a celestial object like this, with a diameter of almost one kilometer, is discovered just two weeks ago.

The discovery was made on 10 October this year by a NASA project in Hawaii (USA), and is a potentially dangerous celestial object will pass about 486,000 kilometers Earth, ie 1.3 times the distance to the moon, and a speed of about 126,000 kilometers per hour.

Miguel Serra noted that while all near-Earth asteroids are known and have more than one kilometer in diameter and approximately 40 percent of which is half a kilometer in diameter, “escape us “Most of celestial objects that have a smaller diameter.

And it is worrying that the number of celestial objects that are tens of meters and capable of destroying a city, Miquel Serra said is not known.

The IAC astronomer Javier Licandro recalled, meanwhile, that celestial objects with more than thirty meters in diameter could cause a catastrophe and one of more than a kilometer almost destroy life on Earth.

According to Miquel Serra early warning projects are needed to find out in advance this type of objects, and therefore shortly begin operating at the Observatorio del Teide on the Canary island of Tenerife, a telescope robot to locate asteroids that could destroy a city.

Javier Licandro, the research group of the Solar System IAC is very important track TB145 2015 because it is quite large and centuries could collide with Earth.

In addition, moves in cometary orbit, so from telescopes in the IAC will be monitored to determine whether an asteroid or comet inactive.

To determine whether it is an asteroid or a comet and inactive to find your path in the future if necessary divert, telescopes as IAC80 and Open Disclosure will be used at the Observatorio del Teide, to observe the visible range and calculate the rotation period from the varying brightness of celestial object.

And since William Herschel telescope and Galileo National in the Roque de los Muchachos Observatory, also in the Canary Islands, will attempt to obtain spectra in the visible and infrared for information on the surface composition of 2015 TB145, while with the Isaac Newton Telescope will be a photometric monitoring in the visible range.

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.

‘Great Pumpkin’ approaches to Earth on the night of Halloween – Milenio.com

A large meteorite, dubbed 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 a phenomenon unusual, that only happens every 10 years.

The asteroid Halloween – El Colombiano

If you fall on Earth would damage regional proportions, but it will be 480,000 kilometers, just beyond the orbit of the Moon

It is the asteroid 2015 TB145, 400 meters long, the asteroid ghost or pumpkin for Halloween this will have its closest approach 31.

And while there is no doubt that there will come closer , according to Paul Chodas , head of the Office of Study of close objects (NEO) spacecraft, which has been discovered on 10 this month reminded that any surprise is possible: Chelyabinski event is cool , this 15-meter asteroid that hit close to that population a few years ago and caused damage to 7,200 buildings in 6 cities and injured 1,500 people.

This, indeed, is 28 times bigger. The closer, rubbing will occur at 12 days and is not visible to the naked eye. Moves to 126,000 kilometers / hour.

Can hit Earth in next visit? After the passage of today will never come so close to within 40 years. It is an asteroid visits us every three years but further away.

No ongoing asteroid known to the planet, with which on average every 10,000 years strikes a rock of 1 kilometer. Which it triggered the extinction of the dinosaurs measuring 10,000 meters, which happens every few hundred thousand years.

The next large asteroid known that Earth will rub in 2027, 1999 AN10, of about 800 meters until you reach a lunar distance, according to the Minor Planet Center.

Today we have identified 1,671 potentially hazardous asteroids, those greater than 150 meters to spend at least 7.4 million kilometers. Asteroids are over 12,000.

But what are the asteroids? Ignacio Ferrin , an astronomer at the University of Antioquia, explains that they are “rock density 2.5 gm / cm3, much like terrestrial rocks. A very common type of rock in them are chondrites, which have high nickel and iron, and thus are magnetic. “

There are some near and others in the main belt between Mars and Jupiter , some of which may have an altered orbit, such as 99942 Apophis, which will pass relatively close to Earth in 2019, says Ferrin.

But not everyone is convinced that 2015 TB145 is an asteroid. It is possible for a comet. One is Lance Benner , the Jet Propulsion Laboratory of NASA. The reason is clear: the comets tend to have elongated orbits

That, plus the high-speed 35 kilometers per second, suggest that possibility.. And as the approach to be followed by observatories radar as the Deep Space Network at Goldstone, California, it would be the first to take a picture of a comet.

But it remains to be seen.

Successfully tested lithium battery last longer – Trade

A team of scientists from the University of Cambridge (UK) has successfully tested a model of battery Lithium longer than at present, and could enable electric cars have the same autonomy than gasoline, according to the magazine “Science”.

The small-scale experiment to test the feasibility of a battery containing lithium and oxygen, which opens the door theoretical production of lithium batteries so far are limited in their capacity.

At present, the ability of battery lithium is limited by the formation of lithium peroxide during discharge, which decreases the efficiency of the battery irreparably by blocking the micropores of the anode receiver, usually carbon.

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

The researchers hope that this advance could accelerate mass production of battery lithium-oxygen load and more efficient for both electric cars to electronics.

The ability of the battery of conventional lithium ion around 80% of rated capacity, as proven by scientists at the University of Cambridge can exceed 93%.

In addition, this new device can be recharged more than 2,000 times and is highly resistant to water, one of the problems of the battery Current.

device has a higher load capacity on the space occupied and could finally make an electric car you have the autonomy to gasoline.

However, these battery of lithium oxygen are more unstable and inefficient in the long term, which has avoided that arise as an alternative

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 for the planet.

“The path of 2015 TB145 is well understood,” he said Paul Chodas, manager of the Center for Near Earth Objects Laboratory NASA JPL in Pasadena (California).

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

asteroid was discovered last October 10 by a telescope in Hawaii (USA) and since then there have been calculations to pinpoint its orbit.

The NASA has said the passage of the asteroid near the Earth is more than a threat, an opportunity to investigate this type of space bodies.

The radio antennas Goldstone complex in California, will be reoriented to monitor and study over TB145, which is moving at an unusually high speed, according to NASA.

The observatory hopes to process images with a resolution of up to two meters per pixel. EFE

Progress in lithium batteries could revolutionize the world of electric cars – The Nacional.com

Scientists at the University of Cambridge (UK) successfully tested a model of lithium battery that brings that technology to a longer useful life and could enable electric cars have as much autonomy as fuel.

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

At present, the capacity of lithium batteries is limited by the formation of lithium peroxide during discharge blocking battery efficiency inevitably to block the micropores of the anode receptor usually carbon.

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

The researchers hope that the findings of his study to accelerate mass production of lithium-oxygen more efficient with higher load both for 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.

Batteries Lithium-oxygen have a greater capacity on the space they occupy and could finally make an electric car 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 Clare Grey material, remember that the experiment is provisional and there are many obstacles to reach a phase of industrial production.

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

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.
                 

Puebla observatory to monitor refined details asteroid – Azteca News

Puebla, Puebla .- On October 31 the asteroid 2015 TB145 pass at a distance of about 525,000 kilometers of our planet, equivalent to 1.3 times the average distance of Earth to the moon, so INAOE tuned instruments to observe it.

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

The researcher INAOE, he said 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 the distance Moon.

He noted that the number of asteroids small, less than one hundred meters, is much higher, hence the scientific importance and from the point of view of security of the planet, have search systems and monitoring of asteroids, particularly those known as Near Earth Objects and even more so-called potentially hazardous asteroids.

asteroid 2015 TB145 was discovered 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.
