CERN Update: The Higgs Boson - Is it the God Particle?

http://facebook.com/ScienceReason ... CERN/LHC Update: "The Higgs Boson - Is it the God Particle?" CERN confirms existence of new particle consistent with Higgs boson. Is the Higgs boson the long-sought "God Particle"? And what do scientists think about the metaphor "The God Particle"? The ATLAS and CMS experiments at CERN presented their latest results in the search for the long-sought Higgs boson. Both experiments see strong indications for the presence of a new particle, which could be the Higgs boson, in the mass region around 126 gigaelectronvolts (GeV). --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/FFreeThinker • http://www.youtube.com/ScienceTV • http://www.youtube.com/Best0fScience • http://www.youtube.com/RationalHumanism --- CERN experiments observe particle consistent with long-sought Higgs boson "We now have more than double the data we had last year," said CERN Director for Research and Computing, Sergio Bertolucci, "that should be enough to see whether the trends we were seeing in the 2011 data are still there, or whether they've gone away. It's a very exciting time." If and when a new particle is discovered, ATLAS and CMS will need time to ascertain whether it is the long sought Higgs boson, the last missing ingredient of the Standard Model of particle physics, or whether it is a more exotic form of the boson that could open the door to new physics. "It's a bit like spotting a familiar face from afar," said CERN Director General Rolf Heuer, "sometimes you need closer inspection to find out whether it's really your best friend, or actually your best friend's twin." The Standard Model gives an extraordinarily precise picture of the matter that makes up all the visible universe, and the forces that govern its behaviour, but there are good reasons to believe that this is not the end of the story. For example, we know from observation that the visible universe is just 4% of what seems to be out there. "It's hard not to get excited by these results," said CERN Research Director Sergio Bertolucci. " We stated last year that in 2012 we would either find a new Higgs-like particle or exclude the existence of the Standard Model Higgs. With all the necessary caution, it looks to me that we are at a branching point: the observation of this new particle indicates the path for the future towards a more detailed understanding of what we're seeing in the data." "We have reached a milestone in our understanding of nature," said CERN Director General Rolf Heuer. "The discovery of a particle consistent with the Higgs boson opens the way to more detailed studies, requiring larger statistics, which will pin down the new particle's properties, and is likely to shed light on other mysteries of our universe." Positive identification of the new particle's characteristics will take considerable time and data. But whatever form the Higgs particle takes, our knowledge of the fundamental structure of matter is about to take a major step forward. • http://press.web.cern.ch/press/PressReleases/Releases2012/PR17.12E.html --- Tags: "god particle" "higgs boson" "higgs particle" god particle higgs boson new higgs-like cern lhc cms atlas experiments physics standard model supersymmetry susy mass matter universe results videos .

Historic Milestone: CERN Discovers Higgs-like Boson

http://facebook.com/ScienceReason ... New particle observed at LHC! CERN Physicists are sure they have found a boson particle -- but is it the long-sought Higgs boson of the Standard Model? The ATLAS and CMS experiments at CERN presented their latest results in the search for the long-sought Higgs boson. Both experiments see strong indications for the presence of a new particle, which could be the Higgs boson, in the mass region around 126 gigaelectronvolts (GeV). --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/FFreeThinker • http://www.youtube.com/ScienceTV • http://www.youtube.com/Best0fScience • http://www.youtube.com/RationalHumanism --- CERN experiments observe particle consistent with long-sought Higgs boson At a seminar and a press conference held at CERN on 4 July 2012 as a curtain raiser to the year's major particle physics conference, ICHEP2012 in Melbourne, the ATLAS and CMS experiments presented their latest preliminary results in the search for the long sought Higgs particle. Both experiments observe a new particle in the mass region around 125-126 GeV. "We observe in our data clear signs of a new particle, at the level of 5 sigma, in the mass region around 126 GeV. The outstanding performance of the LHC and ATLAS and the huge efforts of many people have brought us to this exciting stage," said ATLAS experiment spokesperson Fabiola Gianotti, "but a little more time is needed to prepare these results for publication." "The results are preliminary but the 5 sigma signal at around 125 GeV we're seeing is dramatic. This is indeed a new particle. We know it must be a boson and it's the heaviest boson ever found," said CMS experiment spokesperson Joe Incandela. "The implications are very significant and it is precisely for this reason that we must be extremely diligent in all of our studies and cross-checks." "It's hard not to get excited by these results," said CERN Research Director Sergio Bertolucci. " We stated last year that in 2012 we would either find a new Higgs-like particle or exclude the existence of the Standard Model Higgs. With all the necessary caution, it looks to me that we are at a branching point: the observation of this new particle indicates the path for the future towards a more detailed understanding of what we're seeing in the data." The results presented today are labelled preliminary. They are based on data collected in 2011 and 2012, with the 2012 data still under analysis. Publication of the analyses shown today is expected around the end of July. A more complete picture of today's observations will emerge later this year after the LHC provides the experiments with more data. The next step will be to determine the precise nature of the particle and its significance for our understanding of the universe. Are its properties as expected for the long-sought Higgs boson, the final missing ingredient in the Standard Model of particle physics? Or is it something more exotic? The Standard Model describes the fundamental particles from which we, and every visible thing in the universe, are made, and the forces acting between them. All the matter that we can see, however, appears to be no more than about 4% of the total. A more exotic version of the Higgs particle could be a bridge to understanding the 96% of the universe that remains obscure. "We have reached a milestone in our understanding of nature," said CERN Director General Rolf Heuer. "The discovery of a particle consistent with the Higgs boson opens the way to more detailed studies, requiring larger statistics, which will pin down the new particle's properties, and is likely to shed light on other mysteries of our universe." Positive identification of the new particle's characteristics will take considerable time and data.

CERN 'Higgs Boson' Announcement: We Have Observed A New Particle

In the video dated July 4 2012, Joe Incandela, a spokesman for Cern, announces that scientists "have observed a new particle". "We have quite strong evidence that there's something there. Its properties are still going to take us a little bit of time. "But we can see that it decays to two photons, for example, which tells us it's a boson, it's a particle with integer spin. And we know its mass is roughly 100 times the mass of the proton. And this is very significant. This is the most massive such particle that exists, if we confirm all of this, which I think we will," Mr Incandela, the CMS Spokesperson says. "And this is very, very significant. It's something that may, in the end, be one of the biggest observations of any new new phenomena in our field in the last 30 or 40 years, going way back to the discovery of quarks, for example," he adds. The origin of mass has been fiercely debated for decades **Credit to the UK Telegraph for the amazing video

Giant Solar Tornado Makes a Film Debut

The only thing more terrifying than a giant twister on Earth is one on the face of the sun. A monstrous tornado has been observed erupting on our star, and its numbers are staggering. So big it could swallow five Earths in one gulp, the swirling vortex observed last September and presented at this week's National Astronomy Meeting in England grew to a height of 125,000 miles, about half the distance between Earth and the moon. The temperature of the plume of superheated gas measured between 90,000 and 3.6 million degrees Fahrenheit and was accelerated to speeds approaching 186,000 miles per hour. Discovered by NASA's Solar Dynamic Observatory, this Master Blaster is thought to be the first Solar Tornado ever filmed, and may help us understand the kinds of large particle eruptions that recently came flying at us from the ball of gas. As our local star approaches Solar Max, the peak activity of an 11-year cycle, 2012 is shaping up to be one spectacular year for space weather.

Gigantic Solar Tornado Is 5 Times the Size of Earth--September 2011

Discovered using NASA's Solar Dynamic Observatory satellite, this colossal twisting mass is made up of superheated gas at a temperature of between 90,000 and 3.6 million degrees Fahrenheit. Over the course of three hours, this behemoth reached up from the sun's surface to a height of 125,000 miles, or roughly half the distance between the Earth and the moon. The hot gases were whipped up to nearly 186,000 miles per hour. In comparison, the wind speed of terrestrial tornadoes generally reaches a paltry 100 miles per hour. Scientists have previously seen smaller solar tornadoes with other sun-observing satellites but this one — spotted in September 2011 — is thought to be the first one ever filmed (left). Since then, researchers have seen at least one more solar tornado, an Earth-sized twister seen in the video below. These tornadoes often precede events known as coronal mass ejections — huge eruptions of charged particles that blast out of the sun's surface with tremendous energy. Such flare-ups are thought to be related to interactions among the sun's magnetic field lines, whose corkscrewing movements also shape the solar tornado. The top images and movie were presented at the National Astronomy Meeting 2012 in Manchester, England on Mar. 29. http://www.wired.com/wiredscience/2012/03/gigantic-solar-tornado/ comment-rate-subscribe also watch: http://www.youtube.com/playlist?list=PL20C572EB49403155&feature=view_all

Tornado on the Sun Vast 300,000mph Planet-Sized

A tremendous tornado whirling across the surface of the sun was captured by a NASA satellite recently -- an amazing wonder of the solar system that may be as big as the Earth itself. The video was recorded by the Solar Dynamics Observatory (SDO), a sun-watching satellite that has transmitted a series of stunning photos of solar flares in recent months. The new video shows darker, cooler plasma shifting back and forth above the sun's surface over the span of nearly 30 hours stretching from Feb. 7 to Feb. 8. And the giant tornado may be as large as the Earth itself, with gusts of up to 300,000 mph, explained Terry Kucera, deputy SOHO project scientist and a solar physicist with NASA's Goddard Space Flight Center. "It's about 15,000 degrees Fahrenheit -- relatively cool," Kucera told FoxNews.com. After all, the sun's corona is a whopping 2 million degrees, she explained. Such tornadoes (Kucera classed it a "solar prominence") have been known of for decades; the European Space Agency's SOHO spacecraft captured evidence of them as early as 1996, mainly near the Sun's north and south poles at the time. And though they resemble their cousins here on Earth, they're created entirely differently, Kucera said -- through magnetism, not pressure and temperature fluctuations. "Those motions you see, it's all just moving along the magnetic field somehow -- but we're still looking to understand what's happening with these things," Kucera said. The storm was created by competing magnetic forces, which pull the charged magnetic particles on the sun back and forth, creating a spinning mass of plasma that tracks along strands of magnetic field lines, NASA explained. The spinning top of the tornado is mesmerizing, but Kucera noted the span of the prominence as well. The long, ribbon shapes could span hundreds of thousands of miles, she said. "In total length, this could be dozens of Earths -- quite large," she said. Such detailed, high-resolution recordings of the immense tornadoes was not possible until the launch of SDO. The satellite has several cameras on board that capture solar activity in different wavelengths and frequencies, all in the name of science. "Each wavelength of light tells us something different," she said.

Earth size Tornado's rip up the Sun! (February 17, 2012)

For a 30 hour time frame on (Feb 7-8, 2012) the Solar Dynamics Observatory captured plasma caught in a magnetic dance across the Sun's surface. In this video, cooler plasma material appears as darker spots on a bright background. The SDO spacecraft recorded the video in the extreme ultraviolet range of the light spectrum, giving the movie an eerie yellow hue. NASA released the new SDO video to mark the second anniversary of the spacecraft's mission, which launched on Feb. 11, 2010. The $850 million spacecraft is on a five-year mission to record high-definition videos of the sun to help astronomers better understand how changes in the sun's solar weather cycle can affect life on Earth. The sun is currently in an active period of its 11-year weather cycle. The current cycle is known as Solar Cycle 24 and will peak in 2013.

PREVIEW: Alien Planets & Eyeball Earths

Music by Zero Project. The hunt for planets beyond our solar system has reached a fever pitch. With some 500 planets revealed by ground telescopes, now, the ultimate planet finder, the Kepler space telescope, has released a tsunami of data. Among over a thousand new planet prospects are 200 multi-planet solar systems and 58 worlds in life-friendly orbits. They're all within a narrow window on the sky the size of your hand. That's why this may be the tip of the iceberg in a galaxy that's literally crawling with planets. Scientists are now beginning to envision what these worlds are like, with atmospheres, oceans, geological history. In the process, they are redefining what a planet might need to spawn life.

NASA SDO - M8.7-class Solar Flare, Jan 23, 2012

The Chinese New Year certainly started with a bang this morning. At approx. 04:00 UT a strong and long duration M8.7-class solar flare exploded from Active Region 1402. NASA SDO captured this event and thanks to ESA/NASA SOHO and NASA STEREO Behind spacecrafts, we have also learned of a very quick moving Coronal Mass Ejection. The CME is traveling at approx. 2,200 km per second and the Goddard Space Weather Lab predicts the arrival of this CME on earth to be January 24, 2012 at approx. 14:18 UT (+/- 7 hours). It also shows that Mars will get hit too, several hours after Earth. These kinds of events can cause problems for spacecrafts in geosynchronous, polar and other orbits passing could be affected by the cloud's arrival. In addition, strong geomagnetic storms are possible, so high-latitude sky watchers should be alert for Aurorae. Credit: NASA SDO

NASA SDO - X1.1 Solar Flare, March 5, 2012

After several days of a quiet Sun, the solar activity is now high again. Big sunspot AR1429, which emerged on March 2nd, is crackling with strong flares. This morning brought the strongest so far--an X1-class eruption on March 5th at 0413 UT. This flare propelled a bright Coronal Mass Ejection into Space, which will probably miss Earth, but hit Mercury and Venus. Even if this CME misses, high-latitude sky watchers should still be alert for auroras in the nights ahead. An M2-class eruption from the same sunspot on March 4th produced another, wider CME that might yet intersect Earth. The cloud is expected to deliver a glancing blow to our planet's magnetic field on March 6th at 04:30 UT (+/- 7 hr). Take a look at the forecast from our friends at the NASA Goddard Space Weather Lab: http://iswa.gsfc.nasa.gov/downloads/20120305_085600_anim.tim-den.gif Credit: NASA SDO

NASA SDO - X5.4-class Solar Flare, March 7, 2012

Right at midnight UT time the active region 1429 unleashed a powerful X5.4-class solar flare. X-class flares are the strongest of the flares. They are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms. It appears that right after the large X5.4 flare another slightly lower, X1 flare (5 times smaller) occurred. You can clearly see a wave going across the Sun. We are still gathering data and the Space Weather Forecast Lab will be having updates available soon. Credit: NASA SDO

NASA SDO - Spectacular Prominence Eruption, June 7, 2011

The Sun unleashed an M-2 (medium-sized) solar flare with a substantial coronal mass ejection (CME) on June 7 that is visually spectacular. The large cloud of particles mushroomed up and fell back down looking as if it covered an area of almost half the solar surface. SDO observed the flare's peak at 1:41 AM EST. SDO recorded these images in extreme ultraviolet light and they show a very large explosion of cool gas. It is somewhat unique because at many places in the eruption there seems to be even cooler material -- at temperatures less than 80,000K. When viewed in SOHO's coronagraphs, the event shows bright plasma and high-energy particles roaring from the Sun. This Earth-directed CME is moving at 1400 km/s according to NASA models. Due to its angle, however, effects on Earth should be fairly small. Nevertheless, it may generate space weather effects here on Earth in a few days. Credit: NASA SDO

NASA Science - The Surprising Power of a Solar Storm

A recent flurry of eruptions on the sun did more than spark pretty auroras around the poles. NASA-funded researchers say the solar storms of March 8th through 10th dumped enough energy in Earth's upper atmosphere to power every residence in New York City for two years. "This was the biggest dose of heat we've received from a solar storm since 2005," says Martin Mlynczak of NASA Langley Research Center. "It was a big event, and shows how solar activity can directly affect our planet." Mlynczak is the associate principal investigator for the SABER instrument onboard NASA's TIMED satellite. SABER monitors infrared emissions from Earth's upper atmosphere, in particular from carbon dioxide (CO2) and nitric oxide (NO), two substances that play a key role in the energy balance of air hundreds of km above our planet's surface. "Carbon dioxide and nitric oxide are natural thermostats," explains James Russell of Hampton University, SABER's principal investigator. "When the upper atmosphere (or 'thermosphere') heats up, these molecules try as hard as they can to shed that heat back into space." That's what happened on March 8th when a coronal mass ejection (CME) propelled in our direction by an X5-class solar flare hit Earth's magnetic field. (On the "Richter Scale of Solar Flares," X-class flares are the most powerful kind.) Energetic particles rained down on the upper atmosphere, depositing their energy where they hit. The action produced spectacular auroras around the poles and significant1 upper atmospheric heating all around the globe. "The thermosphere lit up like a Christmas tree," says Russell. "It began to glow intensely at infrared wavelengths as the thermostat effect kicked in." For the three day period, March 8th through 10th, the thermosphere absorbed 26 billion kWh of energy. Infrared radiation from CO2 and NO, the two most efficient coolants in the thermosphere, re-radiated 95% of that total back into space. In human terms, this is a lot of energy. According to the New York City mayor's office, an average NY household consumes just under 4700 kWh annually. This means the geomagnetic storm dumped enough energy into the atmosphere to power every home in the Big Apple for two years. "Unfortunately, there's no practical way to harness this kind of energy," says Mlynczak. "It's so diffuse and out of reach high above Earth's surface. Plus, the majority of it has been sent back into space by the action of CO2 and NO." During the heating impulse, the thermosphere puffed up like a marshmallow held over a campfire, temporarily increasing the drag on low-orbiting satellites. This is both good and bad. On the one hand, extra drag helps clear space junk out of Earth orbit. On the other hand, it decreases the lifetime of useful satellites by bringing them closer to the day of re-entry. The storm is over now, but Russell and Mlynczak expect more to come. "We're just emerging from a deep solar minimum," says Russell. "The solar cycle is gaining strength with a maximum expected in 2013." More sunspots flinging more CMEs toward Earth adds up to more opportunities for SABER to study the heating effect of solar storms. "This is a new frontier in the sun-Earth connection," says Mlynczak, and the data we're collecting are unprecedented." Credit: NASA Science

NASA - Aurorae from Space

Lately, the International Space Station has been flying through geomagnetic storms, giving astronauts an close-up view of the aurora borealis just outside their windows. These videos were taken by the crew of Expedition 30 on board the International Space Station. First, get an introduction into the beauty of aurorae. 1st Segment: The sequence of shots was taken March 3, 2012 from 17:59:48 to 18:16:25 GMT, on a pass from eastern Kenya, near the Indian Ocean, to the South Indian Ocean, east of the Kerguelen Islands. This video begins as the ISS travels southeast from eastern Africa over the Arabian Sea and the Indian Ocean. The first land we see is that of the Mauritius and Reunion Islands east of Madagascar. The pass continues over the Indian Ocean, where there are heavy clouds blocking the view of the water. Finally, the Aurora Australis begins to appear, as well as a faded view of the Milky Way. 2nd Segment: The sequence of shots was taken March 4, 2012 from 17:19:17 to 17:27:10 GMT, on a pass over the South Indian Ocean. This video again focuses on the Aurora Australis as the ISS passes over the South Indian Ocean, from northeast of the Kerugelen Islands to south of Australia. The streaks of the aurora are very visible and active in this video, as the ISS passes right over the green lights. 3rd Segment: The sequence of shots was taken March 10, 2012 from 14:49:58 to 15:05:37 GMT, on a pass from the South Indian Ocean to southeast New Zealand. This video mainly focuses on the Aurora Australis over the Southern Hemisphere. As the ISS traveled southeast and then northeast, the crew captured the bands of the Aurora Australis as the Milky Way made an appearance in the star field. Credit: NASA ISS/JSC/Science@NASA

NASA/ESA SOHO & NASA SDO Comet Meets Sun, October 1, 2011

A comet discovered on Friday September 30, 2011 by an amateur astronomer disintegrated on Saturday October 1, 2011 when it plunged into the Sun. The Corongraph of NASA/ESA's SOHO captured the last few hours of the comet. Very shortly after the comet dove into the Sun a Coronal Mass Ejection (CME) exploded. As of current solar scientists do not believe that a comet can trigger a Coronal Mass Ejection - however, the question of if a comet could cause a magnetic instability on the Sun remains and is being studied. On July 6, 2011 the Solar Dynamics Observatory (SDO) observed a sungrazing comet and it appeared to interact with the plasma and magnetic field as it fell apart. The first two segments in this video are from October 1, 2011 and were observed by NASA/ESA's SOHO spacecraft. The last two segments were captured by NASA's SDO on July 5, 2011.

NASA SDO - M2.6 Solar Flare on January 19, 2012

Today's M2.6-class Solar Flare produced a nice Coronal Mass Ejection, which appears to be Earth directed. Current forecasts have it to arrive on January 21, 2012 at approx. 22:30 UT (let's give or take 7 hours... it's over 90 million mile journey after all). Our friends at the NASA Goddard Space Weather Lab are predicting possible strong geomagnetic storms. What will it mean for us? Possibly some Aurorea and perhaps some communications interruption. No major issues are expected. A view of the Active Regions 1401 and 1402 over the past couple of days shows the development of those beautiful sunspots. Then two views of the solar flare through the SDO instrument before concluding with views from STEREO Ahead and Behind. Credit: NASA SDO & NASA STEREO

NASA SDO - M8.7-Class Solar Flare from January 23, 2012

The Chinese New Year certainly started with a bang this morning. At approx. 04:00 UT a strong and long duration M8.7-class solar flare exploded from Active Region 1402. NASA SDO captured this event and thanks to ESA/NASA SOHO and NASA STEREO Behind spacecrafts, we have also learned of a very quick moving Coronal Mass Ejection. The CME is traveling at approx. 2,200 km per second and the Goddard Space Weather Lab predicts the arrival of this CME on earth to be January 24, 2012 at approx. 14:18 UT (+/- 7 hours). It also shows that Mars will get hit too, several hours after Earth. These kinds of events can cause problems for spacecrafts in geosynchronous, polar and other orbits passing could be affected by the cloud's arrival. In addition, strong geomagnetic storms are possible, so high-latitude sky watchers should be alert for Aurorae. Credit: NASA SDO

NASA SDO - M9-class Solar Flare, July 30, 2011

In the early hours of July 30, 2011 a fairly strong, but brief, M9-class solar flare occurred on Active Region 1261. Because it was brief it appears not to have hurled a large coronal mass ejection (CME) outwards. Additional analysis are underway. Credit: NASA SDO

Higgs Boson Mass Range Excluded By LHC

http://www.quicknuclearscience.webs.com/ The LHC has excluded the higgs boson's mass range between 141-476 GeV, also next year it will look at the lower end of the spectrum to hopefully find or exclude the higgs all together.
