Around midnight UTC last night, Active Region 1429 on the Sun exploded with a fairly large flare: rated at class X5.4 , it was among the largest seen in the current cycle. Video of the flare has been created using images from the Solar Dynamics Observatory: Yowza. This flare was big enough that it may cause some communication issues and will probably lead to some nice aurorae, but otherwise is no… Broadcasting platform : YouTube Source : DiscoverMagazine Discovery Date : 07/03/2012 04:37 Number of articles : 3

(AP) — Three topless Ukrainian protesters were detained Saturday while trying to break into an invitation-only gathering of international CEOs and political leaders to call attention to the needs of the world’s poor. Separately, demonstrators from the Occupy movement marched to the edge of the gathering. After a complicated journey to reach the heavily guarded Swiss resort town of Davos, the Ukrainians… Broadcasting platform : YouTube Source : The Blaze Discovery Date : 28/01/2012 16:01 Number of articles : 2

I know I’ve been writing about the Sun quite a bit lately, but I have a followup to yesterday’s cool video of the big solar flare… and you’re gonna like it.

NASA scientists braced for ‘solar tsunami’ to hit earth

The earth could be hit by a wave of violent space weather as early as Tuesday after a massive explosion of the sun, scientists have warned. The solar fireworks at the weekend were recorded by several satellites, including Nasa’s new Solar Dynamics Observatory which watched its shock wave rippling outwards. Astronomers from all over the world witnessed the huge flare above a giant sunspot the size of the Earth, which they linked to an even larger eruption across the surface of Sun. The explosion was aimed directly towards Earth, which then sent a “solar tsunami” racing 93 million miles across space. Images from the SDO hint at a shock wave travelling from the flare into space, the New Scientist reported. Experts said the wave of supercharged gas will likely reach the Earth on Tuesday, when it will buffet the natural magnetic shield protecting Earth. It is likely to spark spectacular displays of the aurora or northern and southern lights. Scientists have warned that a really big solar eruption could destroy satellites and wreck power and communications grids around the globe if it happened today. Nasa recently warned that Britain could face widespread power blackouts and be left without critical communication signals for long periods of time, after the earth is hit by a once-in-a-generation “space storm”. The Daily Telegraph disclosed in June that senior space agency scientists believed the Earth will be hit with unprecedented levels of magnetic energy from solar flares after the Sun wakes “from a deep slumber” sometime around 2013. Dr Lucie Green, of the Mullard Space Science Laboratory, Surrey, followed the flare-ups using Japan's orbiting Hinode telescope. It remains unclear, however, how much damage this latest eruption will cause the world’s communication tools. “It looks like the first eruption was so large that it changed the magnetic fields throughout half the Sun's visible atmosphere and provided the right conditions for the second eruption. “Both eruptions could be Earth-directed but may be travelling at different speeds. “This means we have a very good chance of seeing major and prolonged effects, such as the northern lights at low latitudes.” A Nasa spokesman was unavailable for comment. http://www.telegraph.co.uk/science/space/7923069/Nasa-scientists-braced-for-sola… added by: slagface

NASA’s New Eye on the Sun Delivers Stunning First Images

ScienceDaily (Apr. 22, 2010) — NASA's recently launched Solar Dynamics Observatory, or SDO, is returning early images that confirm an unprecedented new capability for scientists to better understand our sun's dynamic processes. These solar activities affect everything on Earth Some of the images from the spacecraft show never-before-seen detail of material streaming outward and away from sunspots. Others show extreme close-ups of activity on the sun's surface. The spacecraft also has made the first high-resolution measurements of solar flares in a broad range of extreme ultraviolet wavelengths. “These initial images show a dynamic sun that I had never seen in more than 40 years of solar research,” said Richard Fisher, director of the Heliophysics Division at NASA Headquarters in Washington. “SDO will change our understanding of the sun and its processes, which affect our lives and society. This mission will have a huge impact on science, similar to the impact of the Hubble Space Telescope on modern astrophysics.” Launched on Feb. 11, 2010, SDO is the most advanced spacecraft ever designed to study the sun. During its five-year mission, it will examine the sun's magnetic field and also provide a better understanding of the role the sun plays in Earth's atmospheric chemistry and climate. Since launch, engineers have been conducting testing and verification of the spacecraft's components. Now fully operational, SDO will provide images with clarity 10 times better than high-definition television and will return more comprehensive science data faster than any other solar observing spacecraft. SDO will determine how the sun's magnetic field is generated, structured and converted into violent solar events such as turbulent solar wind, solar flares and coronal mass ejections. These immense clouds of material, when directed toward Earth, can cause large magnetic storms in our planet's magnetosphere and upper atmosphere. SDO will provide critical data that will improve the ability to predict these space weather events. NASA's Goddard Space Flight Center in Greenbelt, Md., built, operates and manages the SDO spacecraft for the agency's Science Mission Directorate in Washington. “I'm so proud of our brilliant work force at Goddard, which is rewriting science textbooks once again.” said Sen. Barbara Mikulski, D-Md., chairwoman of the Commerce, Justice and Science Appropriations Subcommittee that funds NASA. “This time Goddard is shedding new light on our closest star, the sun, discovering new information about powerful solar flares that affect us here on Earth by damaging communication satellites and temporarily knocking out power grids. Better data means more accurate solar storm warnings.” Space weather has been recognized as a cause of technological problems since the invention of the telegraph in the 19th century. These events produce disturbances in electromagnetic fields on Earth that can induce extreme currents in wires, disrupting power lines and causing widespread blackouts. These solar storms can interfere with communications between ground controllers, satellites and airplane pilots flying near Earth's poles. Radio noise from the storm also can disrupt cell phone service. More at link. added by: Almibry
