NASA | SDO Year One

April 21, 2011 marks the one-year anniversary of the Solar Dynamics Observatory (SDO) First Light press conference, where NASA revealed the first images taken by the spacecraft. In the last year, the sun has gone from its quietest period in years to the activity marking the beginning of solar cycle 24. SDO has captured every moment with a level of detail never-before possible. The mission has returned unprecedented images of solar flares, eruptions of prominences, and the early stages of coronal mass ejections (CMEs). In this video are some of the most beautiful, interesting, and mesmerizing events seen by SDO during its first year. In the order they appear in the video the events are: 1. Prominence Eruption from AIA in 304 Angstroms on March 30, 2010 2. Cusp Flow from AIA in 171 Angstroms on February 14, 2011 3. Prominence Eruption from AIA in 304 Angstroms on February 25, 2011 4. Cusp Flow from AIA in 304 Angstroms on February 14, 2011 5. Merging Sunspots from HMI in Continuum on October 24-28, 2010 6. Prominence Eruption and active region from AIA in 304 Angstroms on April 30, 2010 7. Solar activity and plasma loops from AIA in 171 Angstroms on March 4-8, 2011 8. Flowing plasma from AIA in 304 Angstroms on April 19, 2010 9. Active regions from HMI in Magnetogram on March 10, 2011 10. Filament eruption from AIA in 304 Angstroms on December 6, 2010 11. CME start from AIA in 211 Angstroms on March 8, 2011 12. X2 flare from AIA in 304 Angstroms on February 15, 2011 Be sure to vote on your favorite SDO clip here: http://www.nasa.gov/mission_pages/sdo/multimedia/VC-1st-light.html Voting goes from April 21 until May 5.

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

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!

The LHC - The Large Hadron Collider ( L.H.C )

The Large Hadron Collider is the largest and most complex scientific instrument ever built and the highest energy particle accelerator in the world. The accelerator is located 100 m underground and runs through both French and Swiss territory. ( 27km circumference) Year 2008 September 10th, marks the culmination of 20 years of work by over 8000 scientists thousands of engineers, technicians and support staff from over 80 different countries. some critics say that this could create a black hole and suck up the entire world. but many say that even if a black hole is created it will vanish within a millionth of a second.. for more info follow these links.

Copernicus's remains laid to rest -- again

The remains of Nicolas Copernicus, the father of modern astronomy who was born in the 15th century, were identified last November thanks to comparative DNA tests on two strands of hair found in an ancient tome. After undergoing the kind of study that he would have appreciated, Copernicus is laid to rest in a marked grave nearly 500 years after his death.Duration: 02:00

The Electric Universe Pt3 of 4

Pulsars and Comets in the electric universe/plasma cosmology model. See this publication for some more info on this interpretation of pulsars, published and peer reviewed in the journal of astrophysics and space science; http://adsabs.harvard.edu/abs/1995Ap&SS.227..229H A pulsar (pulsating star) is an astronomical object which produces a regular pulse of radio waves (electromagnetic radiation) which is conventionally thought to be due to a rotating neutron star. The Plasma Universe explains pulsars as a magnetospheric transmission line system. Also see this website for more information on electrical activity associated with comets and some other evidence supporting the electric model (with peer reviewed references); http://www.plasma-universe.com/index.php/Comet

The Ascent of Man - 10: World within World 5/5

Part 1: http://www.youtube.com/watch?v=h2cqMDBOrGI Playlist: http://www.youtube.com/view_play_list?p=A3FC4D7ED67F4B1A The inspiration for Carl Sagans 1980 series, Cosmos, Jacob Bronowskis 1973 series, The Ascent of Man, alludes to and seeks to somewhat challenge the notion of some of Charles Darwins conclusions in The Decent of Man. Over the course of thirteen episodes, Bronowski travelled around the world in order to trace the development of human society through its understanding of science. Jacob Bronowski was one of a small group of men and women in any age who find all of human knowledge-the arts and sciences, philosophy and psychology-interesting and accessible. He was not confined to a single discipline, but ranged over the entire panorama of human learning. His book and television series, The Ascent of Man, are a superb teaching tool and a remarkable memorial; they are, in a way, an account of how human beings and human brains grew up together. Carl Sagan, The Dragons of Eden Part 10: World within World Bronowski explores the chemical world: from the periodic table to quantum mechanics.
