NASA SDO - Large Sunspot AR1339, November 1 - 8, 2011

The black and white images show the magnetic field - the field is pointing toward us where it is white. The leading spots all have an intense negative polarity and the following spots are mostly positive. The two polarities are pretty well separated and fairly stable, which is why this region hasn't produced even more dramatic activity. The biggest explosions happen when complex magnetic regions annihilate each other. The glittering moving features around the spots follow the crests of magnetic waves. Not much new flux is emerging into this mature region, but there is a lot going on in the vicinity - and just about everywhere else too if you look carefully. The surrounding filamentary structures are weaker field regions that appear bright in intensity. The movie with the granular yellow background shows the Sun's surface brightness. Sunspot group 11339 is already large when it rotates around to the front side of the Sun. The umbra is the darker, cooler part where the magnetic field is very strong and vertical. The surrounding orange penumbra appears very dynamic because waves in the weaker horizontal magnetic field make it look like material is flowing out of the spot. Watch how the darkest regions develop in time. The largest spot is more than five times the size of our Earth. What you cannot tell from these pictures is which direction the magnetic field is pointing. Credit: NASA SDO

NASA SDO - Growing Sunspot

The video from the Helioseismic and Magnetic Imager onboard SDO shows the Active Region 1393 from January 6 through January 8 and demonstrates how sunspots can quickly change shape and size. Sunspots are planet-sized magnets created by the Sun's inner magnetic dynamo. Like all magnets in the Universe, sunspots have north (N) and south (S) magnetic poles Sunspots, temporary disturbances in the Sun's photosphere, are the most visible advertisement of the solar magnetic field. They appear dark because temperatures are considerably lower than in surrounding areas. Sunspots occur where the magnetic field lines emerge from the inside of the Sun to form expanding loops above its surface. Sunspots usually show up as small forms that are irregularly shaped, and grow within days or weeks to their full size. While they can last weeks or months, they do eventually disappear, often by breaking into smaller and smaller sunspots. 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 - Twist & Eclipse

Over the past 24 hours we have seen some beautiful solar events. None of them have a direct impact on Earth, but they are astonishing to watch. It just shows how an active Star our Sun really is. Far from boring. On December 8, 2011 a twisting prominence eruption occurred on the lower eastern limb. The view through the AIA 304 angstrom filter shows us this beautiful eruption. In the early hours of December 9, 2011 SDO observed a little bit of a different eclipse. An erupting cloud of plasma was eclipsed by a dark magnetic filament. The eruption is still on the far side of the Sun, behind the eastern limb and is slowly moving forward and over the limb sometime next week. In front you can observe the filament of relatively cool dark material floating across the Sun's surface in the foreground. That filament partially blocks the view of the hot plasma eruption behind it. Credit: NASA SDO

NASA SDO - Today's Un-Boring Sun; December 7, 2011

December 7, 2011; Today's Sun in various wavelengths showing various temperatures and layers of the Sun. Not only that, but we also added the Sun's magnetic field lines to the view. These images were taken at approx. the same time We start off looking at the 6,000 degrees C. Photosphere. See the various sunspots on the "surface" of the Sun? Now let's transition into the region between the Chromosphere and the Corona, at about 1 million degrees C. From there we go into a composite of three different wavelengths showing temperatures up to 2 million degrees C. And at the end we add the complex field of Magnetic Field lines to the various active regions. And who says the Sun is boring? Credit: NASA SDO Thanks to Steele Hill

NASA SDO - Filament Snap, November 14, 2011

And within just a few hours the very massive filament (see post from earlier today) is approx. 1/3 shorter. This movie shows the developments from 13:00 to 16:00 UT on November 14, 2011. A solar prominence (also known as a filament when viewed against the solar disk) is a large, bright feature extending outward from the Sun's surface. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's hot outer atmosphere, called the corona. A prominence forms over timescales of about a day, and stable prominences may persist in the corona for several months, looping hundreds of thousands of miles into space. Scientists are still researching how and why prominences are formed. The red-glowing looped material is plasma, a hot gas comprised of electrically charged hydrogen and helium. The prominence plasma flows along a tangled and twisted structure of magnetic fields generated by the sun's internal dynamo. An erupting prominence occurs when such a structure becomes unstable and bursts outward, releasing the plasma. Credit: NASA SDO

NASA SDO - Three in Profile

Three energized active regions that were lined up latitudinally (along a North-South line) rotated into profile view at the Sun's edge and put on a good solar show (Oct. 21-23, 2011). They were observed in extreme ultraviolet light. The magnetic forces of the active regions were feverishly connecting and reconnecting the entire time. Towards the end of the clip, the middle region spurted off a burst of plasma and then the upper one erupted with a flare, followed by cascades of bright loops reorganizing themselves above it. SDO's high resolution images and fast cadence of images let us see a level of detail never before possible. Credit: NASA SDO

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's Kepler Discovery Confirms First Planet Orbiting Two Stars

September 15, 2011 (CERESTV.com) PASADENA, Calif. -- The existence of a world with a double sunset, as portrayed in the film Star Wars more than 30 years ago, is now scientific fact. NASA's Kepler mission has made the first unambiguous detection of a circumbinary planet -- a planet orbiting two stars -- 200 light-years from Earth. Unlike Star Wars' Tatooine, the planet is cold, gaseous and not thought to harbor life, but its discovery demonstrates the diversity of planets in our galaxy. Previous research has hinted at the existence of circumbinary planets, but clear confirmation proved elusive. Kepler detected such a planet, known as Kepler-16b, by observing transits, where the brightness of a parent star dims from the planet crossing in front of it. "This discovery confirms a new class of planetary systems that could harbor life," Kepler Principal Investigator William Borucki, of NASA's Ames Research Center in Moffett Field, Calif., said. "Given that most stars in our galaxy are part of a binary system, this means the opportunities for life are much broader than if planets form only around single stars. This milestone discovery confirms a theory that scientists have had for decades but could not prove until now." A research team led by Laurance Doyle of the SETI Institute in Mountain View, Calif., used data from the Kepler space telescope, which measures dips in the brightness of more than 150,000 stars, to search for transiting planets. Kepler is the first NASA mission capable of finding Earth-size planets in or near the "habitable zone," the region in a planetary system where liquid water can exist on the surface of the orbiting planet. Scientists detected the new planet in the Kepler-16 system, a pair of orbiting stars that eclipse each other from our vantage point on Earth. When the smaller star partially blocks the larger star, a primary eclipse occurs, and a secondary eclipse occurs when the smaller star is occulted, or completely blocked, by the larger star. Astronomers further observed that the brightness of the system dipped even when the stars were not eclipsing one another, hinting at a third body. The additional dimming in brightness events, called the tertiary and quaternary eclipses, reappeared at irregular intervals of time, indicating the stars were in different positions in their orbit each time the third body passed. This showed the third body was circling, not just one, but both stars, in a wide circumbinary orbit. The gravitational tug on the stars, measured by changes in their eclipse times, was a good indicator of the mass of the third body. Only a very slight gravitational pull was detected, one that only could be caused by a small mass. The findings are described in a new study published Friday, Sept. 16, in the journal Science. "Most of what we know about the sizes of stars comes from such eclipsing binary systems, and most of what we know about the size of planets comes from transits," said Doyle, who also is the lead author and a Kepler participating scientist. "Kepler-16 combines the best of both worlds, with stellar eclipses and planetary transits in one system." This discovery confirms that Kepler-16b is an inhospitable, cold world about the size of Saturn and thought to be made up of about half rock and half gas. The parent stars are smaller than our sun. One is 69 percent the mass of the sun and the other only 20 percent. Kepler-16b orbits around both stars every 229 days, similar to Venus' 225-day orbit, but lies outside the system's habitable zone, where liquid water could exist on the surface, because the stars are cooler than our sun. "Working in film, we often are tasked with creating something never before seen," said visual effects supervisor John Knoll of Industrial Light & Magic, a division of Lucasfilm Ltd., in San Francisco. "However, more often than not, scientific discoveries prove to be more spectacular than anything we dare imagine. There is no doubt these discoveries influence and inspire storytellers. Their very existence serves as cause to dream bigger and open our minds to new possibilities beyond what we think we 'know.'"

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.

Spirit Science 12_3 - The Solution

After the Martians collapsed the Atlantean way of life, the Naacals didn't know what to do. They asked for help from the highest conscious beings in our universe, and they received a potential solution. If it could pull it off, we would become something incredibly new and different in the universe. If we did not, we would not survive. Our entire planet was walking a very thin line. www.thespiritscience.net Twitter - @spiritsciences Facebook - www.facebook.com/thespiritscience Flower of Life books - http://www.mediafire.com/?4zx4y9mhasjg5nz See page 104 Volume 1 for this portion of the Human History Story!

Stellar-mass black hole discovered

Our astronomers have detected a stellar-mass black hole in another galaxy, much further away than any other previously known. With a mass above fifteen times that of the sun, this is the second most massive black hole of this type ever discovered. This animation shows how the stellar black hole NGC 300 X-1 might look. Note: there is no audio in this video.

Astronomers

Observes and interprets celestial phenomena and relates research to basic scientific knowledge or to practical problems, such as navigation: Studies celestial phenomena by means of optical, radio, or other telescopes, equipped with such devices as cameras, spectrometers, radiometers, photometers, and micrometers, which may either be on ground or carried above atmosphere with balloons, rockets, satellites, or space probes. Interprets information obtained in terms of basic physical laws. Determines sizes, shapes, brightness, spectra, and motions, and computes positions of sun, moon, planets, stars, nebulae, and galaxies. Calculates orbits of various celestial bodies. Determines exact time by celestial observations, and conducts research into relationships between time and space. Develops mathematical tables giving positions of sun, moon, planets, and stars at given times for use by air and sea navigators. Conducts research on statistical theory of motions of celestial bodies. Analyzes wave lengths of radiation from celestial bodies, as observed in all ranges of spectrum. Studies history, structure, extent, and evolution of stars, stellar systems, and universe. May design new and improved optical, mechanical, and electronics instruments for astronomical research. May specialize in either observational or theoretical aspects of stellar astronomy, stellar astrophysics, interstellar medium, galactic structure, extragalactic astronomy, or cosmology.

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.
