Galileo Sun-Centered System

http://www.myspace.com/acorvettes When Galileo published his book debating the Copernican and Ptolemaic systems, the Church found him guilty of heresy and sentenced him to house arrest for the rest of his life. Today, Galileo is recognized for his revolutionary work in both astronomy and physics, and has been referred to as "the father of modern science." In addition to his findings in support of the Copernican system, his theories regarding falling objects and objects in motion laid the groundwork for classical mechanics. He was also a pioneer in the approach we call the scientific method, which utilizes observation and experiment. In 1992, three hundred and fifty years after his death, the Church officially apologized for condemning Galileo and his scientific research.

Gigantic Solar Tornado Is 5 Times the Size of Earth

This enormous tornado erupting from the surface of the sun is big enough to swallow the Earth. In fact, it could swallow five Earths. 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.

5-Times Size of Earth: Giant Solar Tornado Caught In Rare NASA Tape

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 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.

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.

TORNADO THE SIZE THE EARTH With 300,000 MPH Winds Spotted On The Sun! AMAZINGLY AWESOME! Part Two

17TH FEBRUARY 2012.. 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.

Helmut Jerjen: Tales of stars and stellar systems - part one

In the first of this two-part video Dr Helmut Jerjen tells 'Tales of stars and stellar systems' . The event is part of Mount Stromlo's Centenary Celebrations. Astronomy has arguably had the single largest impact on the development of science, human society and culture over the past 10,000 years. On our journey through space and time we will explore the glorious life of our sun, learn how astrophysical knowledge acquired 100 years ago can help to solve the energy crisis on Earth today, and find out why we should rightfully call ourselves the children of the stars. The discovery of exoplanets is a regular topic in the international news. Dr Jerjen explains how astronomers measure the faint signal from these distant island worlds, show where our place in the Milky Way is, and disclose how the Universe grew a million times bigger on the night of October 6, 1923. Dr Jerjen is a member of academic staff at the Research School of Astronomy & Astrophysics (RSAA) at ANU. As a genuine multi-wavelength astrophysicist he has published over 100 articles in international journals covering topics in the areas of near-field cosmology, stellar populations, galaxy evolution and dark matter. He is the head of the Stromlo Milky Way Satellite Survey team that will make use of the new ANU SkyMapper Telescope to study dark-matter dominated dwarf galaxies in the halo of our Milky Way. Dr Jerjen is passionate about educating future generations of astrophysicists.

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.

Wandering Stars: a tour of the planets

A beauteous rip through the solar sytem, based on NASA's Science on a Sphere program "The Wanderers." In ancient times, humans watched the skies looking for clues to their future and to aid in their very survival. They soon observed that some stars were not fixed, but moved in the sky from night to night. They called these stars the wanderers. At the center of our solar system is the sun, binding the planets with its gravitational pull. From our viewpoint on earth, the sun appears small in the sky, but in reality it dwarfs even Jupiter, the largest planet in the solar system. The distance from the sun to the small worlds traveling it are vast. Light takes eight minutes to reach earth, and nearly a day to reach the farthest known bodies. Join us now as we tour our solar system, starting with sun-baked mercury and traveling to the remotest outskirts, where small, icy bodies move with only the faintest connection to our sun. Mercury Mercury, the closest planet to Sun is also the smallest terrestrial planet. It orbits so swiftly that its year lasts only 88 Earth days. The airless cratered surface could almost be mistaken for our moon, relentlessly bombarded by meteoroids for four and a half billion years. One of these encounters left a giant scar called the golarus basin, one of the largest impact sights in the solar system. Temperatures on the surface of mercury can reach a blistering 800 degrees Fahrenheit, and can dip to 300 degrees below zero on the night side. Venus Venus, as seen from Earth, is the brightest object in sky after the Sun and Moon. Russian probes were the first to land on Venus in the 1970's and 1980's. Venus's surface is volcanic. Its atmosphere is composed of thick, dense carbon dioxide with sulfuric acid clouds. Both are potent greenhouse gases that trap incoming sunlight. Venus rotates slowly—one Venusian day lasts almost four Earth months. Earth Earth is the only planet with life as we know it. The atmosphere and temperatures are "just right" for life. It is the only known body in our solar system where water can exist as a gas, liquid, and solid. Vast oceans dominate surface of the planet. Seasonal changes occur on the surface. Earth has a solid surface that constantly shifts due to plate tectonics. Mars Once geologically active, Mars has the largest dormant volcano in the solar system, Olympus Mons. It also hast the longest valley in the solar system, called Valles Marineris. Mars has a thin, atmosphere primarily composed of carbon dioxide. Surface conditions are dynamic. Mars has seasons as well as massive dust storms that cover the planet. Its surface features include the smooth, low-lying northern hemisphere and the craggy, heavily-cratered southern uplands. Evidence suggests that Mars had water running on its surface at some time in the past. Asteroid belt The asteroid belt is composed of small rocky pieces. The big question is "What happened here?" and "Why no planets?" The asteroid Ceres is large enough to be classified as a dwarf planet. Jupiter Jupiter is the largest and most massive planet in the Solar System. It rotates rapidly, completing one rotation every 10 hours. Long-lasting, high-speed winds and storms dominate Jupiter's atmosphere. Jupiter has a faint planetary ring system and over 63 moons. The largest moons, discovered by Galileo in 1610, vary widely. Io is volcanically active. Europa's cracked surface likely hides an ocean below. Ganymede is the largest moon in the Solar System. Callisto is heavily cratered. Saturn Saturn's seemingly serene atmosphere hides powerful storms and winds on its surface. Saturn is known for its extensive ring system made of chunks of ice, rock, and dust with small moonlets embedded within the rings. Saturn has more than 60 moons. Conditions vary among the moons. Titan, the largest moon, has a thick, smoggy, atmosphere covering its icy surface with lakes of liquid methane or ethane. Small Enceladus has water and ice geysers at its south pole. Its water vapor coat other nearby moons and create a thin Saturn ring. Uranus Uranus receives 400 times less sunlight than Earth. Uranus lies nearly sideways, making its axis nearly parallel to the plane of the Solar System. This extreme tilt give rise to seasons that last nearly 28 Earth years. Uranus as many moons and a faint ring system. It has only been visited by one spacecraft, Voyager 2, in 1986. Like the other giant planets, Uranus's atmosphere is primarily hydrogen and helium with a trace of methane gas over deep clouds, giving it a pale blue-green tint. Neptune Neptune also has many moons and a faint ring system. Its Great Dark Spot, a large storm with extremely strong winds, disappeared in the 1990s. Neptune's vivid blue color is due to its frigid temperature: -371°F (-224 °C).

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.

Planetary Science: Exploring The Solar System

Science & Reason on Facebook: http://tinyurl.com/ScienceReason Science@ESA (Episode 7): Planetary science - Exploring our backyard, the Solar System (Part 2) In this seventh episode of the Science@ESA vodcast series Rebecca Barnes continues to journey through the wonders of modern astronomy bringing us closer to home as we begin to explore the Solar System. We'll discover the scale and structure of the Solar System, find out why we explore it and introduce the missions launched on a quest to further investigate our local celestial neighbourhood. --- Please subscribe to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceMagazine • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- Planetary science is the scientific study of planets (including Earth), moons, and planetary systems, in particular those of the Solar System and the processes that form them. It studies objects ranging in size from micrometeoroids to gas giants, aiming to determine their composition, dynamics, formation, interrelations and history. It is a strongly interdisciplinary field, originally growing from astronomy and earth science, but which now incorporates many disciplines, including planetary astronomy, planetary geology (together with geochemistry and geophysics), physical geography (geomorphology and cartography as applied to planets), atmospheric science, theoretical planetary science, and the study of extrasolar planets. Allied disciplines include space physics, when concerned with the effects of the Sun on the bodies of the Solar System, and astrobiology. There are interrelated observational and theoretical branches of planetary science. Observational research can involve a combination of space exploration, predominantly with robotic spacecraft missions using remote sensing, and comparative, experimental work in Earth-based laboratories. The theoretical component involves considerable computer simulation and mathematical modelling. Planetary scientists are generally located in the astronomy and physics or earth sciences departments of universities or research centres, though there are several purely planetary science institutes worldwide. There are several major conferences each year, and a wide range of peer-reviewed journals. • http://en.wikipedia.org/wiki/Planetary_science --- The Solar System is made up of the Sun and all of the smaller objects that move around it. Apart from the Sun, the largest members of the Solar System are the eight major planets. Nearest the Sun are four fairly small, rocky planets - Mercury, Venus, Earth and Mars. Beyond Mars is the asteroid belt - a region populated by millions of rocky objects. These are left-overs from the formation of the planets, 4.5 billion years ago. On the far side of the asteroid belt are the four gas giants - Jupiter, Saturn, Uranus and Neptune. These planets are much bigger than Earth, but very lightweight for their size. They are mostly made of hydrogen and helium. Until recently, the furthest known planet was an icy world called Pluto. However, Pluto is dwarfed by Earth's Moon and many astronomers think it is too small to be called a true planet. An object named Eris, which is at least as big as Pluto, was discovered very far from the Sun in 2005. More than 1,000 icy worlds such as Eris have been discovered beyond Pluto in recent years. These are called Kuiper Belt Objects. In 2006, the International Astronomical Union decided that Pluto and Eris must be classed as "dwarf planets". Even further out are the comets of the Oort Cloud. These are so far away that they are invisible in even the largest telescopes. Every so often one of these comets is disturbed and heads towards the Sun. It then becomes visible in the night sky. • http://sci.esa.int/science-e/www/area/index.cfm?fareaid=7 .

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's Kepler Mission Announces Latest Planetary Discovery

The Kepler mission's science team announced its latest finding at a press conference on Monday, Dec. 5, 2011. The team announced the confirmation of Kepler-22b, its first planet found in the "habitable zone," the region where liquid water could exist on a planet's surface. The planet is about 2.4 times the radius of Earth, orbits around a star similar to our sun and is located 600 light-years away. Scientists don't yet know if Kepler-22b has a predominantly rocky, gaseous or liquid composition, but its discovery is a step closer to finding Earth-like planets. The planet's host star belongs to the same class as our sun, called G-type, although it is slightly smaller and cooler. Kepler also has discovered 1,094 new planet candidates, nearly doubling its previously known count. Since the last catalog was released in February, the number of planet candidates identified by Kepler has increased by 89 percent and now totals 2,326. Of these, 207 are approximately Earth-size, 680 are super Earth-size, 1,181 are Neptune-size, 203 are Jupiter-size and 55 are larger than Jupiter. The findings, based on observations conducted May 2009 to September 2010, show a dramatic increase in the numbers of smaller-size planet candidates.

NASA SDO - X1.9 Class Solar Flare, November 3, 2011.mov

"Bad Boy" active region 1339 continues to flare. At 20:27 UT a solar flare peaked at X1.9. X-class flares are pretty massive and are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms. The location of this sunspot/active region is still not quiet Earth directed. Credit: NASA SDO

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.
