NASA SDO - Plasma Indirection

As if it could not make up its mind . . . darker, cooler plasma slid and shifted back and forth above the Sun's surface seen here for 30 hours (Feb. 7-8, 2012) in extreme ultraviolet light. An active region rotating into view provides a bright backdrop to the gyrating streams of plasma. The particles are being pulled this way and that by competing magnetic forces. They are tracking along strands of magnetic field lines. This kind of detailed solar observation with high-resolution frames and a four-minute cadence was not possible until SDO, which launched two years ago on Feb. 11, 2010. So it's our 2nd Anniversary!

Thunderbolts the Electric Universe and Plasma Physics

Thunderbolt the Tutorial is about the electrical model of the universe. In the universe plasma makes up 99.99% of everything we can see. Our current model has big flaws that has forced scientist to dream up things that don't exist in order to explain things that we see out there in space. Yet the electrical model can explain most of these things. So why don't we hear about this model? It's not mentioned on TV shows like The Universe or How The Earth Was Made, Discovery Channel, or even PBS, never talk about it, WHY? Electricity, that's why! If the universe has electrical currents flowing thru it, and it does, then it's just a matter of time before we would learn how to harness that energy. You would have to buy a devise that would output the power, but after that it would be free. Imagine being able to drive anywhere you wanted to without having to stop and fill up your tank every 200 or 300 miles. Imagine your home when it's 110 degrees outside, but inside a nice 75 degrees with no electric bill to eat up all your hard earned money. Could it be true? I believe it could, and this would defiantly be a reason for the energy companies to not want this known. _____________________________________________________ Related videos: The truth about dark energy, it's really zero point energy. http://www.youtube.com/watch?v=EqaLSulA_3I A short 10 min video about the electrical universe and plasma physics. http://www.youtube.com/watch?v=gPiGWIf3FjA Dr. Chuck Missler on The Electric Universe 1hr 43min lecture. http://www.youtube.com/watch?v=mxLn06k2ATo Wallace Thornhill on the misconceptions of the electrical universe 13 min. http://www.youtube.com/watch?v=aa9tsMztZPY Universe - The Cosmology Quest Pt 1 http://www.youtube.com/watch?v=L6EGpg_BVBg&feature=channel_video_title Universe - The Cosmology Quest Pt 2 http://www.youtube.com/watch?v=t7uT0JuKT8Q&feature=relmfu ______________________________________ For more informative videos like this one: http://youtube.com/davnxs http://youtube.com/thetruthalwaysaddsup _____________________________________ Now you can add my Playlist to your Channel.

Space Odyssey: Voyage To The Planets 1 - BBC

Space Odyssey: Voyage To The Planets This two-part science fiction docu-drama examines the possibilities of a dangerous, manned space mission to explore the inner and outer planets of the Solar system. Five astronauts pilot the nuclear thermal rocket powered Pegasus spacecraft on a tour of the solar system. Their mission is a collaboration of the NASA, CSA, ESA and РКА space agencies and takes the crew to Venus, Mars, a close flyby of the Sun, Jupiter's moon Io and Europa, Saturn, Pluto, and the fictional Comet Yano-Moore. Most of the planetary destinations the crew reaches are followed by a manned landing there. Prior to the mission large tanks of hydrogen were deposited in stable orbits around the planets to allow the crew to refuel to have sufficient delta-v for the multi-year mission. The crew encounter many hardships and disappointments along the way. A Venus EVA that almost ends in disaster when the lander Orpheus encounters launch delays, the near-loss of the shield during the aerobrake in Jupiter's upper atmosphere (according to the first part of the miniseries) and the loss of samples from Jupiter's moon Io all test the crew's resolve. The most devastating blow comes when the ship's medical officer dies of solar radiation-induced lymphoma in Saturn orbit, forcing the crew to decide whether to continue the mission to Pluto, or abort and return to Earth. In the original British release, the crew decides to press on to Pluto, making history.

Hubble Deep Field: The Most Imp. Image Ever Taken (Redux)

This is the latest incarnation of the HDF video. The narration has been edited to include research from a paper in Physical Review Letters (2004) which puts the size of the universe at 46.5 billion light years, not 78 billion as I originally stated. In the video narration, I round that value up to 47 billion light years.

Stephen Hawking - We must colonize space in order to survive

Note: I edited this video, here is the full 10mins. Stephen Hawking: Asking big questions about the universe http://www.youtube.com/watch?v=xjBIsp8mS-c http://www.ted.com In keeping with the theme of TED2008, professor Stephen Hawking asks some Big Questions about our universe -- How did the universe begin? How did life begin? Are we alone? -- and discusses how we might go about answering them. PLEASE SUBSCRIBE TO: http://www.youtube.com/user/TEDtalksDirector "Since, in the long run, every planetary civilization will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring--not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive... If our long-term survival is at stake, we have a basic responsibility to our species to venture to other worlds." Carl Sagan, Pale Blue Dot, 1994 "We need the stars... We need purpose! We need the image the Destiny [to take root among the stars] gives us of ourselves as a purposeful, growing species. We need to become the adult species that the Destiny can help us become! If we're to be anything other than smooth dinosaurs who evolve, specialize and die, we need the stars.... When we have no difficult, long-term purpose to strive toward, we fight each other. We destroy ourselves. We have these chaotic, apocalyptic periods of murderous craziness." Octavia Butler, Parable of the Talents, 1998 "I don't think the human race will survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I'm an optimist. We will reach out to the stars." Stephen Hawking, interview with Daily Telegraph, 2001 "The dinosaurs became extinct because they didn't have a space program. And if we become extinct because we don't have a space program, it'll serve us right!" Larry Niven, quoted by Arthur Clarke in interview at space.com, 2001 "In time, [a Martian] colony would grow to the point of being self- sustaining. When this stage was reached, humanity would have a precious insurance policy against catastrophe at home. During the next millennium there is a significant chance that civilization on Earth will be destroyed by an asteroid, a killer plague or a global war. A Martian colony could keep the flame of civilization and culture alive until Earth could be reverse- colonized from Mars." Paul Davies, The New York Times, 2004 "We must turn our guns away from each other and outwards, to defend the Earth, creating a global and in space network of sensors and telescopes to find asteroids that could destroy our planet and create the systems to stop them. It makes no sense to dream great dreams while waiting to be hit by a train." Buzz Aldrin and Rick Tumlinson, Ad Astra Online, 2006

He is best known for his eponymous laws of planetary motion, codified by later astronomers based on his works "Astronomia nova", "Harmonices Mundi", and "Epitome of Copernican Astrononomy". They also provided one of the foundations for Isaac Newton's theory of universal gravitation. During his career, Kepler was a mathematics teacher at a seminary school in Graz, Austria, an assistant to astronomer Tycho Brahe, the court mathematician to Emperor Rudolf II, a mathematics teacher in Linz, Austria, and an adviser to General Wallenstein. He also did fundamental work in the field of optics, invented an improved version of the refracting telescope (the Keplerian Telescope), and helped to legitimize the telescopic discoveries of his contemporary Galileo Galilei. Kepler lived in an era when there was no clear distinction between astronomy and astrology, but there was a strong division between astronomy (a branch of mathematics within the liberal arts) and physics (a branch of natural philosophy). • http://en.wikipedia.org/wiki/Johannes_Kepler .

Line spectrum of hydrogen atom

The Ruther Fords Alpha particle-gold foil experiment has proved that most of the mass of an atom is concentrated only in a very small region and thus he called this region as the nucleus of atom. Ruther Ford proposed that (BUT WITHOUT ANY EXPERIMANTAL EVIDENCES) electrons revolved around their nuclei in circular orbits with which are just sufficient to balance the attractive force by nuclei. Unfortunately no scientists have questioned this high-speed motion of electrons around the nucleus and this was the beginning of the development of many misleading theories in the history of physical science. Matter wave, uncertainty principle, electron cloud around the nucleus, wave particle duality for particles etc. Charged particles like electron have a standing- electric field and magnetic field in right angle regardless of any kind of its motions.Uncharged particles like neutron have a standing- magnetic field.Since the standing- electric and magnetic fields, an electron cannot travel in a straight line when it accelerated.When a neutron is accelerated, its standing- magnetic field makes it to oscillate. In essence, a particles standing field lines is the reason for the wave nature when it moves at a high speed.The Davisson and Germer experiment showed that particles behave as wave when they are accelerated. But without knowing the structure of particles they blindly supported the Louis DeBroglies matter wave theory.This matter wave theory has led to the development of the quantum mechanical model of atom.The model says that, the nucleus of an atom is surrounded by a series of stationary waves. These waves have crests at certain points, each complete standing wave representing an orbit. The absolute square of the amplitude of the wave at any point at a given time is a measure of the probability that an electron will be found there. Thus, an electron can no longer be said to be at any precise point at any given time. This series of stationary waves by the electrons are used today for explaining all phenomenon that generated by atoms. Jumping of electrons: The space matter density decreases with the increasing of the distance from the nucleus. When an electron oscillates in an atom, for the every oscillation toward the direction of the nucleus, the high density space matter in the inner region of the atom expels the electron to an outer low density space matter region. Line spectrum of hydrogen atom: When the electron shell of a hydrogen atom is excited it will oscillate in its natural frequency, and so the electron present in the shell. This oscillation of the electron causes the emission of the shortest wavelength Lyman series photon (because that frequency is the natural frequency of the electron shell of hydrogen atom) and jumps from the shell to an outer transitory shell. If there is no any further excitation for the atom, the electron will instantaneously falls back to its original shell. Also, this fall into the shell can cause, the shell get excited in a nominal fashion and the emission of a low intensity photon in the natural frequency of the shell. But, if the transitory shell (to which the electron has initially jumped) is simultaneously excited by some ways (for example, collision of an energetic electron from an external source-in a discharge tube or collision between atom),the electron will again get excited and emit a photon in a longer wavelength, in the natural frequency of that transitory shell. Also, this excitation of the electron causes a further jumping to a more outer transitory shell, and these processes can be continued until the electron is expelled out from the atom and to turn the atom into plasma of hydrogen at a very high temperature.For very jumping of the electron to a more and more outer transitory shells, and the excitation of that transitory shell can cause the emission of more and more long wavelength photons, and this is the reason for the emission of more long wavelength photons like Balmer series, Paschen series, Brackett series, Pfund series etc. http://www.physics-edu.org

Earth Sized Tornado Spins On Sun's Surface Feb-2012.mpg

Vast solar tornado spins on the sun 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.

5-times size of Earth: Giant solar tornado caught in rare NASA tape (VIDEO).mp4

For more exclusive information on UFOs, visit: http://erigia.blogspot.com/2012/05/les-theories-du-complot-revendication.html 5 fois la taille de la Terre: Géant tornade solaire pris dans la NASA cassette rare (VIDEO): Une tornade géante solaire - cinq fois le diamètre de la Terre - tourbillonnant à la vitesse incroyable de certains mph 186000 a été capté sur vidéo par l'Observatoire de la NASA Solar Dynamics. C'est la première fois un géant solaire twister a été capturé sur vidéo. Tornades solaires, connus sous le nom des protubérances solaires, sont façonnées par le champ magnétique du soleil et se produisent souvent pendant les éjections de masse coronale - explosions énormes de plasma solaire. La vitesse de gaz tourbillonnant solaires peut parfois atteindre plusieurs milliers de miles par heure. Cette tornade 124 000-mile de haut a été filmé le 25 Septembre 2011, mais la vidéo n'a été rendu public lors de la réunion national d'astronomie à Manchester (Royaume-Uni) le jeudi. Xing Li, un astronome de l'Université d'Aberystwyth au Pays de Galles, estime que le constat est un "vrai petit bijou d'un événement de frapper l'imagination, et il est un bon moyen d'étudier les structures magnétiques dans l'atmosphère du soleil." Les scientifiques pensent que l'étude de tornades solaires permettra de comprendre les causes des tempêtes de l'espace en général, qui est encore l'un des grands mystères de notre système solaire. ---------------------------------------------------------------------------------------------- A giant solar tornado - five times the Earth's diameter - swirling at incredible speed of some 186,000 mph has been captured on video by NASA's Solar Dynamics Observatory. ­This is the first time a giant solar twister has been caught on video. Solar tornadoes, known as solar prominences, are shaped by the sun's magnetic field and often occur during coronal mass ejections -- huge explosions of solar plasma. The speed of swirling solar gases can sometimes reach several thousand miles per hour. This 124,000-mile-tall tornado was filmed on September 25, 2011, but the video was only released to the public at the National Astronomy Meeting in Manchester (UK) on Thursday. Xing Li, an astronomer at Aberystwyth University in Wales, believes the finding is a "real gem of an event to fire the imagination, and it is a good way to study magnetic structures in the sun's atmosphere." Scientists believe that study of solar tornadoes will help understand the causes of space storms in general, which is still one of the great mysteries of our solar system.

1of5_Cosmic Odyssey-Hubble Heritage

This is part 1 of a 5 part episode. To watch the full show go to my channel (Zuke696) then go to my Playlist, find the show then click Play All - Hubble's Heritage - In 1929, astronomer Edwin Hubble made one of the greatest discoveries in the history of science -- the expansion of the universe. To honor this king of cosmology, an orbiting observatory named the Hubble Space Telescope was launched in 1990 after years of research and delay. Hubble's Heritage takes a closer look at this instrument, from its beginning as a flawed engineering nightmare to its evolution, through corrective optics, into humanity's eyes on the universe. Viewers see some of the astonishing images captured by the Hubble Space Telescope through the years and learn of their significance to astronomers. Designers of the next generation of space telescopes explain the challenges that must be met before Hubble's successors can reveal more mysteries of the universe.

ESO 20 Richest eXoPlanetary System Ever [HD] Discovered by HARPS (not HAARP!)

~credits video: http://youtube.com/ESOobservatory Astronomers using ESO instruments have discovered a remarkable extrasolar planetary system that has some striking similarities to our own Solar System. At least five planets are orbiting the Sun-like star HD 10180, and the regular pattern of their orbits is similar to that observed for our neighbouring planets. One of the new extrasolar worlds could be only 1.4 times the mass of the Earth, making it the least massive exoplanet ever found. This video podcast explains how these faraway planets were detected and exactly what we know about them. Astronomers using ESO's world-leading HARPS instrument have discovered a planetary system containing at least five planets, orbiting the Sun-like star HD 10180. The researchers also believe the system has two other planets, one of which would have the lowest mass ever found, making the system similar to our own Solar System in terms of the number of planets. Furthermore, the scientists find that the location of the planets follows a regular pattern, as also seen in our own Solar System The team of astronomers used the HARPS spectrograph, attached to ESO's 3.6-metre telescope at La Silla, Chile. HARPS is an instrument with unrivalled stability and great precision, and the world's most successful exoplanet hunter. The astronomers, led by Christophe Lovis from the Geneva Observatory, studied the Sun-like star HD 10180 over a period of six years! This star is located 127 light-years away in the southern constellation Hydrus ("the Male Water Snake"). Thanks to the 190 individual HARPS measurements, the astronomers detected the wobbles of the star caused by five or more planets. The five strongest signals correspond to planets with Neptune-like masses — between 13 and 25 Earth masses — which orbit the star in between 6 to 600 days. The astronomers have also strong reason to believe that two other planets are present. One would be a Saturn-like planet orbiting in 2200 days. The other, having a mass of only about 1.4 times that of the Earth would be the least massive exoplanet ever discovered. This suspected planet is very close to its host star and so it is likely to be very hot. One 'year' on this planet lasts only 1.18 Earth-days! The newly discovered Solar System is unique in several respects. First of all, with at least five Neptune-like planets lying within a distance equivalent to the orbit of Mars, this system is more populated than our own Solar System in its inner region, and has many more massive planets there. Furthermore, the system probably has no Jupiter-like gas giant. In addition, all the planets seem to have almost circular orbits. Dynamical studies of the new system reveal complex interactions between planets and give us insights into its long-term evolution. Using the new discovery as well as data for other planetary systems, the astronomers discovered that the locations of the planets seem to follow a regular pattern — similar to the "Titius-Bode" law that exists in our Solar System. This could be a general signature of how planetary systems form. Another important result is that all very massive planetary systems are found around massive and metal-rich stars, while the four lowest-mass systems are found around lower-mass and metal-poor stars. These properties confirm current theoretical models. There is no doubt that this remarkable discovery highlights the fact that we are now entering a new era in exoplanet science: the study of complex planetary systems and not just of individual planets!! And with HARPS, European astronomers will be a driving force behind this transition. --- ESOcast is produced by ESO, the European Southern Observatory.

Universe 114 Beyond Big Bang 17 Copernicus

The History Channel Australia & New Zealand The Universe : 1/14 Beyond The Big Bang : 1/7 Copernicus Learn about Copernicus' theories of a sun-centered universe. --- It all began inside a violent, blinding explosion that threw everything into chaos. Ever since, our greatest thinkers have peered into that chaos in search of order, logic & the answers to where we began. As earlier generations learned to decipher the cosmic clues of how we came to be, we stepped from revelation to revelation; epiphany to epiphany. Aristotle told us the world was round. Ptolemy conceived of a system of planets, stars & sun. Copernicus placed the sun at the center of this system. Galileo confirmed it. Newton explained what held it all together. Einstein offered insight into what fueled it. Hubble proposed it started with a "Big Bang". Our search for answers has shaped how we have evolved as thinking creatures. The Big Bang is the history of why & how we think about who & what we are. We'll contemplate how various cultures believe the world began & how it will all end...& what comes after. & for the first time, we'll be able to see what it might have all looked like, sitting in God's front row seats. Using unprecedented cutting edge animation, The Big Bang will recreate that amazing moment when everything started. With interviews from the world's leading physicists, engineers & historians we will employ every storytelling tool to make complex & confusing ideas clear, exciting & dramatic. Recreations, visual metaphors & first-person accounts will explain concepts like: the formation of galaxies, the existence of other dimensions & the idea of a parallel universe. The Big Bang will pose one of history's greatest questions, Where do we begin? --- http://www.thehistorychannel.com.au

It is named after the American astronomer Edwin Hubble. Although not the first space telescope, the Hubble is one of the largest and most versatile, and is well-known as both a vital research tool and a public relations boon for astronomy. The HST is a collaboration between NASA and the European Space Agency, and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope. Space telescopes were proposed as early as 1923. The Hubble was funded in the 1970s, with a proposed launch in 1983, but the project was beset by technical delays, budget problems, and the Challenger disaster. When finally launched in 1990, scientists found that the main mirror had been ground incorrectly, severely compromising the telescope's capabilities. However, after a servicing mission in 1993, the telescope was restored to its intended quality. Hubble's orbit outside the distortion of Earth's atmosphere allows it to take extremely sharp images with almost no background light. Hubble's Ultra Deep Field image, for instance, is the most detailed visible-light image ever made of the universe's most distant objects. Many Hubble observations have led to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe. The Hubble is the only telescope ever designed to be serviced in space by astronauts. There have been five servicing missions, the last occurring in May 2009. Servicing Mission 1 took place in December 1993 when Hubble's imaging flaw was corrected. Servicing missions 2, 3A, and 3B repaired various sub-systems and replaced many of the observing instruments with more modern and capable versions. However, following the 2003 Space Shuttle Columbia accident, the fifth servicing mission was canceled on safety grounds. After spirited public discussion, NASA reconsidered this decision, and administrator Mike Griffin approved one final Hubble servicing mission. STS-125 was launched in May 2009, and installed two new instruments and made numerous repairs. The latest servicing should allow the telescope to function until at least 2014, when its successor, the James Webb Space Telescope (JWST), is due to be launched. The JWST will be far superior to Hubble for many astronomical research programs, but will only observe in infrared, so it will complement (not replace) Hubble's ability to observe in the visible and ultraviolet parts of the spectrum. • http://en.wikipedia.org/wiki/Hubble_Space_Telescope .

NASA SDO - Aurora; What Causes Them?

Aurora are colorful lights in the night time sky primarily appearing in Earth's polar regions. But what causes them? The culprit behind aurora is our own Sun and the solar plasma that is ejected during a magnetic event like a flare or a coronal mass ejection. This plasma travels outward along with the solar wind and when it encounters Earth's magnetic field, it travels down the field lines that connect at the poles. Atoms in the plasma interacts with atoms in Earth's upper atmosphere.
