Karen C. Fox, NASA's Goddard Space Flight Center A giant sunspot – a magnetically strong and complex region on the sun's surface – has just appeared over the sun's horizon. This is the third trip for this region across the face of the sun, which takes approximately 27 days to make a complete rotation. Scientists track sunspots that are part of active regions, which often produce large explosions on the sun such as solar flares and coronal mass ejections, or CMEs. Each time an active...

X-class solar flare
2014-02-25 08:24:39

[ Watch the Video: SDO Observes Strong X-class Solar Flare ] Karen C. Fox, NASA's Goddard Space Flight Center The sun emitted a significant solar flare, peaking at 7:49 p.m. EST on Feb. 24, 2014. NASA's Solar Dynamics Observatory, which keeps a constant watch on the sun, captured images of the event. Solar flares are powerful bursts of radiation, appearing as giant flashes of light in the SDO images. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically...

IRIS Spotted Its Largest Solar Flare In January
2014-02-22 05:28:40

[ Watch the Video: IRIS Spots Its Largest Solar Flare ] April Flowers for redOrbit.com - Your Universe Online The strongest solar flare since NASA's Interface Region Imaging Spectrograph (IRIS) launched in the summer of 2013 was observed on January 28 of this year. Solar flares are bursts of X-rays and light that stream out into space, disrupting long-range radio transmission on Earth and satellite functions in space. What sets them off, however, is still a mystery for scientists....

Mid-Level Solar Flare Emitted By Sun Feb. 3, 2014
2014-02-04 12:12:58

Karen C. Fox - NASA's Goddard Space Flight Center, Greenbelt, Md. The sun emitted a mid-level solar flare, beginning at 11:57 p.m. EST on Feb. 3, 2014, and peaking at midnight EST. NASA released images of the flare as captured by NASA's Solar Dynamics Observatory. 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...

The first powerful “X-class” solar flare of 2014, in association with another solar phenomenon, a giant cloud of solar particles known as a coronal mass ejection (CME), erupted from the sun on Tuesday, sending radiation and particles speeding toward Earth and disrupting operations on the ground. NEWARK, NJ (PRWEB) January 10, 2014 The first powerful “X-class” solar flare of 2014, in association with another solar phenomenon, a giant cloud of solar particles known as a coronal mass...

The first powerful "X-class" solar flare of 2014, in association with another solar phenomenon, a giant cloud of solar particles known as a coronal mass ejection (CME), erupted from the sun on Tuesday, sending radiation and particles speeding toward Earth and disrupting operations on the ground. NASA reported on Wednesday that Orbital Sciences Corp., a commercial spaceflight company on a cargo delivery mission to the International Space Station, had called off its rocket launch that day...

NASA CRaTER Radio Sounds Of Space
2014-01-10 10:11:26

Brett Smith for redOrbit.com - Your Universe Online A new NASA-backed Internet radio station from the moon may not have Miley Cyrus on its playlist or give away free concert tickets to the seventh caller, but scientists from the space agency are expecting it to be a hit with astrophysicists. The CRaTER Live Internet Radio Station takes cosmic radiation data on a live stream from NASA's Lunar Reconnaissance Orbiter and converts it into a constant flow of soothing cosmic music. The...

Rocket Launches Affected By Space Radiation
2014-01-09 10:06:19

NASA On Jan. 8, 2014, Orbital Sciences Corp. elected to scrub that day's launch attempt of an Antares rocket from NASA’s Wallops Flight Facility, Wallops Island, Va., due to unusually high levels of space radiation – an example of the ways in which space weather can affect human technology. Monitoring for space radiation – which refers to excessive high-energy protons in near-Earth space, often funneled in from space in association with an event on the sun such as the solar flares...

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...

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...
