Mid-Level Solar Flare Seen By NASA's Solar Dynamics Observatory
2014-03-13 12:05:22

Karen C. Fox, NASA The sun emitted a mid-level solar flare, peaking at 6:34 p.m. EDT on March 12, 2014, and NASA's Solar Dynamics Observatory, or SDO, captured an image of it. 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...

2014 Spring Eclipse Season Starts For NASA's Solar Dynamics Observatory
2014-03-04 08:55:45

Karen C. Fox, NASA The 2014 spring eclipse season NASA's Solar Dynamics Observatory begins Feb. 27, 2014. These seasons – a time when Earth blocks SDO's view of the sun for a period of time each day - last around three weeks and happen twice a year near the equinoxes. The eclipses are fairly short near the beginning and end of the season but ramp up to 72 minutes in the middle. Any spacecraft observing the sun from an orbit around Earth has to contend with such eclipses, but SDO's...

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...

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...

Lunar Transit Seen By NASA's Solar Dynamics Observatory
2014-01-30 13:36:48

Karen C. Fox - NASA's Goddard Space Flight Center, Greenbelt, Md. On Jan 30, 2014, beginning at 8:31 a.m EST, the moon moved between NASA’s Solar Dynamics Observatory, or SDO, and the sun, giving the observatory a view of a partial solar eclipse from space. Such a lunar transit happens two to three times each year.  This one lasted two and one half hours, which is the longest ever recorded. When the next one will occur is as of yet unknown due to planned adjustments in SDO's orbit....

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...

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...

NASA's Solar Observing Fleet Will Be Watching Comet ISON's Journey Around The Sun
2013-11-23 08:07:02

NASA It began in the Oort cloud, almost a light year away. It has traveled for over a million years. It has almost reached the star that has pulled it steadily forward for so long. On Thanksgiving Day, Nov. 28, 2013, Comet ISON will finally sling shot around the sun. Here its inward journey through the solar system will end -- either because it will break up due to intense heat and gravity of the sun, or because, still intact, it speeds back away, never to return. Catalogued as C/2012...
