First X-class Flare Of 2014 Unleashed By The Sun
2014-01-08 10:55:47

[ Watch The Video: SDO Captures Release of X1.2 Class Solar Flare ] NASA Update: January 8, 2014 The Jan. 7, 2014, X-class flare was also associated with a coronal mass ejection, or CME, another solar phenomenon that can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground. The European...

NASA's Solar Dynamics Observatory Sees Giant Sunspots
2014-01-08 07:21:33

NASA An enormous sunspot, labeled AR1944, slipped into view over the sun's left horizon late on Jan. 1, 2014. The sunspot steadily moved toward the right, along with the rotation of the sun, and now sits almost dead center, as seen in the image above from NASA's Solar Dynamics Observatory. Sunspots are dark areas on the sun's surface that contain complex arrangements of strong magnetic fields that are constantly shifting. The largest dark spot in this configuration is approximately two...

Sun Emits Mid Level Solar Flare Jan. 7, 2014
2014-01-07 12:11:43

NASA The sun emitted a mid-level solar flare, peaking at 5:13 a.m. EST on Jan. 7, 2014. Images of the flare were captured by NASA's Solar Dynamics Observatory and showed that it came from an active region on the sun that currently sports one of the largest sunspots seen in the last 10 years. Sunspots are regions of strong and complex magnetic fields on the sun's surface. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere...

First Gamma Ray Study Gravitational Lens
2014-01-06 15:27:47

[ Watch the Video: Fermi Provides New Details About Gravitational Lenses ] Brett Smith for redOrbit.com - Your Universe Online A gravitational lens is created when a galaxy or other massive object bends and amplifies light heading toward an observer from a more distant source and a new paper from an international team of researchers has reported the first-ever gamma ray study of the cosmic phenomenon. The paper, which will be published in an upcoming edition of Astrophysical Journal...

WASHINGTON, Jan. 6, 2014 /PRNewswire-USNewswire/ -- An international team of astronomers, using NASA's Fermi observatory, has made the first-ever gamma-ray measurements of a gravitational lens, a kind of natural telescope formed when a rare cosmic alignment allows the gravity of a massive object to bend and amplify light from a more distant source.

Sun Emitted Two Solar Flares Saying Goodbye To 2013 And Hello To 2014
2014-01-03 07:27:26

NASA The sun ushered out 2013 and welcomed 2014 with two mid-level flares on Dec. 31, 2013 and Jan. 1, 2014. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, anywhere from minutes to hours....

NASA's Solar Dynamics Observatory Shows the Sun's Rainbow Of Wavelengths
2013-12-18 09:54:43

[ Watch the Video: SDO’s View Of Our Jewel Box Sun ] NASA Telescopes help distant objects appear bigger, but this is only one of their advantages. Telescopes can also collect light in ranges that our eyes alone cannot see, providing scientists ways of observing a whole host of material and processes that would otherwise be inaccessible. A new NASA movie of the sun based on data from NASA's Solar Dynamics Observatory, or SDO, shows the wide range of wavelengths – invisible to...

Solar Ultra-Violet Imager Cleared For Installation Onto GOES-R Spacecraft
2013-12-17 13:44:39

NASA The Geostationary Operational Environmental Satellite – R known as GOES-R Series Program completed its next instrument, SUVI or the Solar Ultra-Violet Imager, which is now ready for integration onto the GOES-R spacecraft. SUVI is a telescope that will observe the sun in the extreme ultraviolet wavelength range and provide full-disk solar images around the clock. The instrument will identify active regions on the sun, including solar flares and eruptions, which could lead to...

Sun Emits Another X-Class Solar Flare
2013-11-19 11:53:37

NASA Adding on to a series of solar flares throughout October and November, the sun emitted another significant solar flare on Nov. 19, 2013, peaking at 5:26 a.m. EST. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. To see how this event may impact Earth,...

Sunspots Moving Across The Sun
2013-11-14 14:28:37

[ Watch The Video: Sputtering Spot – The Last Days of AR11890 ] NASA Two large, complex sunspots are moving across the face of the sun. One, which produced considerable solar activity in the past weeks, has almost rotated off completely. A new sunspot rounded into view on Nov. 11, 2013 and is now making its way across the Earth-side of the sun. An active region can contain one or more sunspots. The National Oceanic and Atmospheric Administration numbers active regions consecutively as...

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...
