The Bio Website EurekaMag.com publishes insights into all areas of biological science. The latest insights cover Drosophila which are small flies which have been been heavily used in research in genetics as a model organism genetics, cell-biology, biochemistry, and developmental biology, and Solar Flare which is a large energy release at the sun's surface. The insight into Killer Whale covers this toothed predatory whale belonging to the oceanic dolphin family. Mannheim, Germany (PRWEB)...

December 25 Solar Storm Could Knock Out Radio Signals
2011-12-29 04:49:43

Scientists have warned of a major solar storm hitting the Earth that could possibly knock out radio signals. Experts expect radio blackouts for a few days after the radiation from the coronal mass ejection (CME) hits our planet. The flare is part of a larger increase in activity in the Sun, which is expected to peak around 2013. "Category G1 (Minor) geomagnetic storms are expected 28 and 29 December due to multiple coronal mass ejection arrivals," the National Oceanic and Atmospheric...

NASA: Killer Solar Flares A Physical Impossibility
2011-11-11 11:09:25

[ Watch the Video ] Given a legitimate need to protect Earth from the most intense forms of space weather — great bursts of electromagnetic energy and particles that can sometimes stream from the sun — some people worry that a gigantic "killer solar flare" could hurl enough energy to destroy Earth. Citing the accurate fact that solar activity is currently ramping up in its standard 11-year cycle, there are those who believe that 2012 could be coincident with such a flare....

SDO Spots Largest Sunspots In Years
2011-11-04 11:20:44

NASA's Solar Dynamics Observatory (SDO) spotted one of the largest new sunspots to have appeared on the surface of the sun in years. The area is nearly 25,000 miles wide, which is over three times larger than the Earth. NASA said the region has already experienced about eight solar flares, including an M-class flare on November 2. The space agency also said that X-class flares are possible, which includes the largest possible solar flares. The sun shot off a flare from this region...

Image 1 - Hinode's First Light And Five More Years
2011-11-01 12:55:16

On October 28, 2006, the Hinode solar mission was at last ready. The spacecraft launched on September 22, but such missions require a handful of diagnostics before the instruments can be turned on and collect what is called "first light." Hopes were high. Hinode had the potential to provide some of the highest resolution images of the sun the world had ever seen -- as well as help solve such mysteries as why the sun's atmosphere is a thousand times hotter than its surface and how the...

Image 1 - STEREO Celebrates Five Years of Science

[ Watch Video 1 ] | [ Watch Video 2 ] On October 25, 2006 a Delta II rocket launched from Cape Canaveral carrying two nearly identical spacecraft. Each satellite was one half of a mission entitled Solar TErrestrial RElations Observatory (STEREO) and they were destined to do something never done before — see the entire sun simultaneously. The sun rotates, of course, so there's no part of the sun we haven't at some point observed from our vantage point on Earth. But watching this...

NASA will begin development and testing of two science instruments, in cooperation with the European Space Agency (ESA), to be placed on ESA's newly selected Solar Orbiter mission. The spacecraft will study the sun from a closer distance than any previous mission. At its closest approach, the European-led project will operate approximately 21 million miles from the sun's surface, near the orbit of Mercury, roughly 25 percent of the distance from the sun to the Earth. This unique vantage...

Image 1 - Geomagnetic Storm Could Cause Unusual Aurora Activity
2011-09-27 09:42:00

[ Watch the Video ] NASA said on Monday that a "strong-to-severe" geomagnetic storm has hit Earth and could cause a rise in aurora borealis activity. The space agency said the sun unleashed an X1.9-category flare on Saturday morning, causing the geomagnetic storm to reach Earth at a Kp index of 9 in some places on Monday morning. The sun's "Active Region 1302" is the culprit in the incident.  Its bursts of radiation is so intense it could send auroras as far south as Colorado....

The Secret Lives Of Solar Flares
2011-09-20 09:12:45

  [ View the Video ] One hundred and fifty two years ago, a man in England named Richard Carrington discovered solar flares. It happened at 11:18 AM on the cloudless morning of Thursday, September 1st, 1859. Just as usual on every sunny day, the 33-year-old solar astronomer was busy in his private observatory, projecting an image of the sun onto a screen and sketching what he saw. On that particular morning, he traced the outlines of an enormous group of sunspots. Suddenly,...

Photosphere -- The photosphere of an astronomical object is the region at which the optical depth becomes one. In other words, the photosphere is the place where an object stops being transparent. It is typically used to describe the Sun or another star. Because stars are large balls of gas, they have no solid surface. However, there is a depth at which the gas stops being transparent to photons, and this depth provides a visual surface to the star. The Sun's photosphere has a...

Corona -- The corona is the luminous "atmosphere" of the Sun extending millions of kilometers into space, most easily seen during a total solar eclipse. An interesting feature of the corona is the fact that it is much hotter than the visible "surface" of the Sun; the photosphere is approximately 6000°C compared to the corona at over one million °C. The corona is much less dense than the photosphere, however, and so produces less light. The exact mechanism by which the corona is...

Chromosphere -- The chromosphere (literally, "color sphere") is a thin layer of the Sun's atmosphere just above the photosphere, roughly 10,000 kilometers deep. The chromosphere is more visually transparent than the photosphere. The most common solar feature within the chromosphere are spicules, long thin fingers of luminous gas which appear like the blades of a huge field of fiery grass growing upwards from the photosphere below. Spicules rise to the top of the chromosphere and then sink...

Solar Wind -- Solar wind, a stream of particles (mostly high-energy protons ~ 500 Kev) that is continually ejected from the surface of the Sun. The composition of this plasma is identical to the Sun's corona, 73% hydrogen and 25% helium with the remainder as trace impurities, and is ionized. Near Earth, the velocity of the solar wind varies from 200km/s-889km/s. The average is 450 km/s. Approximately 3000 tons of material is lost from the Sun every hour as solar wind. Since solar...

Solar Maximum -- The Sun, a roiling ball of plasma, occupies its place in space approximately 93 million miles from Earth. Though it seems simple to inhabitants of this planet -- the Sun shines, giving light and heat -- the processes occurring in the Sun are so complex that many scientists devote their careers to just one aspect of solar activity. Changes in the activity of the Sun particularly engage solar scientists. Whether fluctuations in the solar magnetic field, expulsions of...
