Instant Replay of Stellar Eruption

Astronomers are watching the astronomical equivalent of an instant replay of a spectacular outburst from the unstable, behemoth double-star system Eta Carinae, which was initially seen on Earth nearly 170 years ago. Astrophysicists affiliated with UC Santa Barbara and Las Cumbres Observatory Global Telescope Network (LCOGT) contributed to the study. Read more at Futurity:

Seeing the Future in the Stars - HubbleSite.org

Astronomers use Hubble images of the giant star cluster Omega Centauri to predict where the stars will be in a decade or more. The cluster's 10 million stars, among the first stars to form in the universe, are in constant motion. Studying their movements helps scientists to understand the formation of the universe. This video is from HubbleSite, the online home of the Hubble Space Telescope. Learn more about this topic.

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.

Comet Harpoon Being Developed by NASA

To extract samples from wily comets, which have just a millionth of Earth's gravitational pull, a harpoon- or ballista-style device may be the best option. To test the idea, NASA engineers have constructed a six-foot-wide harpoon to whack rock samples in a laboratory.

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 - 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.

NASA SDO - X2-class Solar Flare, January 27, 2012

Our "bad boy" sunspot 1402 continues to unleash flares. At 18:37 UT this active region produced the largest category of flares; an X-class flare. It measured X2 to be exact. Since this active region is rotating over the limb of the Sun the eruption was not Earth directed. But energetic protons accelerated by the blast are now surrounding our planet and a S1-class radiation storm is in progress. S1-class is the lowest of 5 (S1 to S5) and has no biological impact, no satellite operations are impacted but some minor impact on HF radio is experienced. Credit: NASA SDO

Today we were treated to a very special sight; the Moon came in between the SDO satellite and the Sun. For 1 hour and 41 minutes team SDO observed the Lunar Transit. This event only happens a few times a year but gives the SDO Team an opportunity to better understand the AIA instrument on SDO and give it a fine tune. This video shows today's Lunar Eclipse in a variety of wavelengths the AIA instrument observes. Each wavelength shows us a different temperature and layer of the Sun, allowing us to study the Sun and its activities. Credit: NASA SDO

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 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
