Kepler 22b New Planet Discovered Earth like Characteristics -- News Story

Kepler-22b New Planet With Earth-Like Characteristics Discovered In Habitable Zone thoughts NASA's Kepler Confirms Its First Planet in Habitable Zone of Sun-like Star: Kepler 22-b (5/12/2011) thoughts NASA's Kepler Mission Announces Latest Planetary Discovery thoughts This is amazing news according to reports NASA announced the discovery of Kepler-22b this is great the first planet the Kepler spacecraft has discovered in the habitable zone, an area with a distance from a star where temperatures will permit the existence of liquid water.Reports say the discovery of Kepler-22b which is 600 light-years away from Earth, brings scientists one step closer to finding a planet that could possibly harbor life Earth may not be the only one This is a major milestone on the road to finding Earth's twins Kepler's results continue to demonstrate the importance of NASA's science missions, which aim to answer some of the biggest questions about our place in the universe Kepler-22b has several Earth-like characteristics according to reports The new planet's temperature is around 72 degrees Fahrenheit and its radius is 2.4 times Earth's. The planet completely orbits its star, which is similar to our sun, every 290 days, just 75 days shy of an Earth year Reports say that the National Optical Astronomy Observatory announced the discovery of Kepler-21b, a new planet with a radius 1.6 times Earth's. But unlike Kepler-21b, which is only about 3.7 million miles away from its sun and is therefore a scorching 2,960 degrees Fahrenheit, Kepler-22b is about 79 million miles from its sun, coming in at a pleasant 72 degrees. it's not yet clear if Kepler-22b is composed or rock, gas or liquid according to reports. Scientists use the Kepler spacecraft to discover new planets by analyzing extremely faint dips in light from far-away stars. These "dips" occur each time the planet passes between the Kepler and its sun, therefore obstructing the star's light. In order for a planet to be confirmed, scientists must observe the celestial body orbit its sun three times according to sources Kepler-22B takes 290 days to orbit its sun, it took nearly three Earth years for scientists to confirm that it was a planet.

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 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

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

Universe 114 Beyond Big Bang 47 Galileo

The History Channel Australia & New Zealand The Universe : 1/14 Beyond The Big Bang : 4/7 Galileo Learn about Galileo's bold moves of challenging the church with his theories of the 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
