ONGOING ERUPTION OF SINABUNG VOLCANO, INDONESIA
Until 2010, Indonesia's Sinabung volcano was dormant, with no confirmed eruptions in the historical record. A brief burst of activity in August and September 2010 caused the temporary evacuation
of about 30,000 nearby residents. Just three years later, fresh gas and ash plumes marked the arrival of a new series of eruptions that have continued into late January, 2014.

10/02/2014...Etats Unis, Californie: Les scientifiques qui analysent les algues au large de la côte de
San Diego y ont confirmé la présence de césium cette semaine, un isotope radioactif directement liée à la centrale de Fukushima Daiichi.



13:28












 









Faisant partie du projet en cours  “Kelp Watch 2014» , les institutions gouvernementales et universitaires ont commencé à recevoir les résultats des échantillons des algues
varech et des algues géantes Kelp recueillies le long de la côte de la Californie, ils confirment une présence radioactive plus élevée que la
normale. 
«Nous essayons de comprendre si des éléments radioactif émanant de Fukushima ont déjà atteint  notre écosystème », a déclaré le Dr Matthew Edwards , un professeur
de l'Université d'État de San Diego . «Que nous soyons de l'autre côté du Pacifique ne signifie pas que nous soyons protégé des radiations émises par l'accident de Fukushima" .
Bien que les scientifiques affirment que les niveaux de césium reste très faibles, la méfiance du public ne fait que croître compte tenu du
refus persistant du gouvernement à informer la population de la côte ouest sur les questions liées aux radiations émise par la centrale de Fukushima accidentée.
Pourtant cette nouvelle découverte coïncide avec les déclarations faites par des chercheurs de l'Institut de Physique de la Croix en
Espagne , qui prédisait l' arrivée début 2014 de rayonnement de Fukushima le long de la côte ouest de l'Amérique du Nord .
Suite à la découverte récente de niveaux de rayonnement de plus
de 1400 % supérieures à la normale sur une plage de Californie et que le gouvernement continue de présenter sans risque des experts indépendants ont
mis en garde les parents de ne pas laisser les enfants jouer sur les plages de Californie, le sable y est à risque disent ils .
Malgré les tentatives des médias pour minimiser l'importance de la catastrophe en cours, cette nouvelle découverte n'a fait que confirmer l'accumulation continue de rayonnement
dans les eaux de la côte Ouest des Etats Unis.
Compte tenu de la capacité des rayonnements à accumuler dans les écosystèmes marins, beaucoup craignent que les mortalités massives de la
vie marine constatés ces dernier temps tout le long de la côte ouest soit liées à l'augmentation continue d'isotopes radioactifs . 
Effectivement les découvertes récentes d'hécatombes massives de la vie marine sur la côte ouest est inquiétante, les étoiles de mer et les
sardines sont mystérieusement atteintes d'anomalies étranges et mortelles depuis quelques mois ( voir cet article précédent ).
Malgré que le gouvernement tente de rassurer le public qu'il n'y a absolument aucun risque actuellement , des dizaines de millions de doses de iodure de potassium ont
été discrètement acheté par le ministère de la Santé et des Services sociaux.
Les experts prédisent que la probabilité d'une augmentation de césium dans l'océan Pacifique semble inévitable, et que la radioactivité
risque de durée environ une quarantaine d'année.

'Tatooine' Alien Planets May Form Far from Twin Suns

Worlds with twin suns like Luke Skywalker's fictional home world Tatooine in "Star Wars" may be born far from the stellar heart of their alien solar systems, scientists say.


Although Earth may orbit around a single star, most sun-like stars are binaries — two stars orbiting each other as a pair. In fact, there are many three-star systems, even going up as high as
seven-star systems.


Worlds that orbit around binary stars are known as circumbinary planets. The first real-life alien planet
with two suns ever discovered by astronomers is Kepler-16b, a gas giant found orbiting the star Kepler-16 about 200 light-years from Earth. [NASA Discovers 1st Real-Life 'Tatooine' Planet (Gallery)]


 


Planets are born from protoplanetary disks of gas and dust that orbit stars. Scientists had thought the very strong gravitational pull binary stars would exert on these disks might disturb
the material within too much for it to easily coalesce into worlds. This made the existence of circumbinary planets in real life a bit of a mystery.

How 'Tatooine' alien planets are born


To learn more about how circumbinary worlds form, researchers analyzed the twin-sun planet
Kepler-34(AB)b, which is located about 4,900 light-years from Earth. This world, also known as Kepler-34b, is about 22 percent of the mass of Jupiter (the largest gas giant in our solar
system) and 76 percent the width of Jupiter. It orbits its two sunlike stars at about the same distance as Earth is from the sun, and was discovered used NASA's Kepler space telescope.


The scientists performed high-resolution, 3D computer simulations of the early stages of planet formation around binary stars. These used an intricate model that calculated the effect of
gravity and physical collisions on and between one million planetary building blocks, each 60 miles (100 kilometers) wide.


The researchers discovered the majority of the simulated exoplanets that resulted originated far from their binary stars.


"Taking into account data on collisions as well as the physical growth rate of planets, we found that Kepler 34(AB)b would have struggled to grow where we find it now," study author Zoe
Leinhardt, an astrophysicist at the University of Bristol in England, said in a statement.


In the area close to binary stars, the planetary building blocks experienced what the researchers called "super-catastrophic erosion events," breaking up into smaller chunks instead of
merging into planetary embryos. This made circumbinary planets in the inner parts of binary systems unlikely, they said.

Twin-sun planet migration


The researchers suggest that Kepler 34(AB)b, like many other known circumbinary planets, may
have migrated inward from where they originally formed to where astronomers see them now. A minimum safe distance for Kepler 34(AB)b's formation would be about 1.5 astronomical units (AU).
(One AU is the average distance between Earth and the sun.)


"Our results seem to indicate that all inner circumbinary planets have migrated," Leinhardt told Space.com.


One possible exception may be the circumbinary planet Kepler-47c, which is further away from its
stars than any other known circumbinary planet.


"Circumbinary planets have captured the imagination of many science-fiction writers and filmmakers," study lead author Stefan Lines at the University of Bristol in England said in a
statement. "Our research shows just how remarkable such planets are. Understanding more about where they form will assist future exoplanet discovery missions in the hunt for Earth-like
planets in binary star systems."


Future research will involve more complex models incorporating gas into the protoplanetary disk, which should drag on planetary building blocks in the disk and could significantly change its
dynamics.


"Most of the mass in the disk is thought to be in gas," Leinhardt said. "The gas should make the environment even less conducive to growth."


In addition, the planetary building blocks in the research team's models are currently large and all start at the same size.


"They are large because we are limited by our computational capability," Leinhardt said. "We have been working over the past year to make our (computer) code faster and able to run with
larger numbers of particles, from millions to billions."

Bold Prediction: Intelligent Alien Life Could Be Found by 2040



By Mike Wall, Senior Writer   |   February 10, 2014 07:14am ET




       

















This exoplanet orbits the star Gliese 667 C, which belongs to a
triple system. The six Earth-mass exoplanet circulates around its low-mass host star at a distance equal to only 1/20th of the Earth-Sun distance. The host star is a companion to two
other low-mass stars, which are seen here in the distance.

PALO ALTO, Calif. — The first detection of intelligent extraterrestrial life will likely come within the next quarter-century, a prominent alien hunter predicts.


By 2040 or so, astronomers will have scanned enough star systems to give themselves a great shot of discovering alien-produced electromagnetic signals, said Seth Shostak of the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, Calif.


"I think we'll find E.T. within two dozen years using these sorts of experiments," Shostak said here Thursday (Feb. 6) during a talk at the 2014 NASA Innovative Advanced Concepts (NIAC)
symposium at Stanford University. [13 Ways to Hunt Intelligent Alien Life]


 


"Instead of looking at a few thousand star systems, which is the tally so far, we will have looked at maybe a million star systems" 24 years from now, Shostak said. "A million might be the
right number to find something."


 



Do you believe alien life exists elsewhere in the universe?


Yes - We may not have found them yet, but they're out
there.No - Aliens are just part of science
fiction.I'm not sure

Many potentially habitable worlds


Shostak's optimism is based partly on observations by NASA's planet-hunting Kepler space
telescope, which has shown that the Milky Way galaxy likely teems with worlds capable of supporting life as we know it.


"The bottom line is, like one in five stars has at least one planet where life might spring up," Shostak said. "That's a fantastically large percentage. That means in our galaxy, there's on
the order of tens of billions of Earth-like worlds."


Shostak and his colleagues think at least some of these worlds host intelligent aliens — beings that have developed the capability to send electromagnetic signals out into the cosmos, as
human civilization does every second of every day. So they're pointing big radio dishes toward the heavens, hoping to detect something produced by living beings.


 



This search started in 1960, when pioneering astronomer Frank Drake scanned two sun-like stars with an 85-foot-wide (26 meters) West Virginia antenna. It has ramped up considerably over the
past half-century, as astronomers have taken advantage of significant advances in electronics and digital technology.


However, getting enough funding to keep scanning the skies is a constant problem. For example, the Allen Telescope Array in northern California — which the SETI Institute uses — was designed
to consist of 350 radio dishes, but just 42 have been built to date. And the array had to go into hibernation in April 2011 due to budget shortfalls. (It came back online in December of that
year after more funding was found.)


The funding situation colors any discussion of SETI activities and timelines, Shostak said.


The 24-year estimate, for example, "depends on continued SETI funding, which is in dire straits right now," he told Space.com after his talk at the NIAC symposium.

A three-way race to find life in space


The search for alien life does not focus solely on technological societies, of course. Many other scientists are
keying in on simple life forms, which must be distributed much more commonly throughout the universe.


The first evidence of microbial life on Earth, for instance, dates from 3.8 billion years ago — just 700 million
years after our planet formed. But it took another 1.7 billion years for multicellular life to evolve. Humans didn't emerge until 200,000 years ago, and we've become a truly technological
species in just the last century or so.


Shostak thus views the alien life hunt as a three-way race. The contenders are researchers looking for advanced, intelligent civilizations; scientists scouring solar-system bodies such as
Mars and Jupiter's moon Europa for simple organisms; and researchers focusing on finding signs of microbial life on nearby exoplanets using future instruments such as NASA's $8.8 billion

Tonight for February 11, 2014

As dusk turns into darkness on February 11, look for the bright stars Castor, Pollux and Procyon in the vicinity of the moon and Jupiter.



If it’s at all clear in your part of the world, you can’t miss the moon and the planet Jupiter at nightfall. These two rank as the brightest and second-brightest celestial bodies in the
February 2014 evening sky. Both of these worlds – the moon and Jupiter – shine in front of the constellation Gemini the Twins on the night of February 11.


The waxing gibbous moon will leave the constellation Gemini after a day or two, but Jupiter will remain in
front of Gemini until early July 2014. So you can use brilliant Jupiter to find Castor and Pollux for months to come.


Despite tonight’s blinding moonlight, you may be able to make out Gemini’s two brightest stars, Castor and Pollux. You also have a good chance of seeing
the brilliant star on the opposite side of tonight’s moon from Castor and Pollux. That’s Procyon, the brightest star in the constellation Canis Minor the Lesser Dog.


Drawn an imaginary line from Procyon and through the gap between Castor and Pollux, and you’re pointing in the direction of Polaris, the North Star. In other words, Castor and Pollux are to the north of Procyon, and
Polaris marks the end of the journey. Past Polaris, you start to go southward again.


The Gemini stars and Procyon are found in the eastern half of sky at nightfall and early evening. They’ll climb upward throughout the early evening hours, until Procyon transits
– climbs to its highest point for the night – somewhere around 10 p.m. local time. At Denver, Colorado, Procyon transits at 22:11 (10:11 p.m.) MST on February 11, 2014. Click here to know when Procyon transits in your sky.




The stars – like the midday sun – reach their highest point when they cross the meridian



When any celestial body transits, it is said to reside on the meridian – the imaginary semi-circle that arcs across the celestial sphere from south to north. When a heavenly body
transits the meridian, it’s neither in the eastern half of sky nor in the western half of sky. A transiting body can only be at one of three places: at zenith (straight overhead), south
of zenith or north of zenith.


Whenever Procyon crosses the meridian, so does that tiny gap between Castor and Pollux. Use the moon to find the stars Castor, Pollux and Procyon tonight, and then use the planet Jupiter
to find these stars in the months ahead.
