Karen C. Fox, NASA's Goddard Space Flight Center The sun emitted a mid-level solar flare, peaking at 12:20 p.m. EDT on July 8, 2014, and NASA's Solar Dynamics Observatory captured images of the event. 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...

NASA's STEREO Mission Being Prepped For Upcoming Orbital Phase
2014-07-04 10:27:41

[ Watch the Video: STEREO Solar Conjunction ] Gerard LeBlond for redOrbit.com - Your Universe Online NASA’s STEREO mission began in 2006 and has been providing scientists with images from the far side of the sun since February 2011. The spacecraft duo that were placed in orbit around the sun are now about to embark on the next phase of their mission. The two STEREO (Solar Transfer Relations Observatory) probes orbit the sun at different speeds and different locations. “Both...

Sun Has Bad Weather Just Like On Earth
2014-06-26 03:31:08

Royal Astronomical Society Just like on Earth, the Sun has spells of bad weather, with high winds and showers of rain. But unlike the all-too-frequent storms of the UK and Ireland, rain on the Sun is made of electrically charged gas (plasma) and falls at around 200,000 kilometers an hour from the outer solar atmosphere, the corona, to the Sun's surface. And the thousands of droplets that make up a 'coronal rain' shower are themselves each as big as Ireland. Now a team of solar...

coronal puff
2014-06-23 11:26:58

Royal Astronomical Society (RAS) A suite of Sun-gazing spacecraft, SOHO, STEREO and Solar Dynamics Observatory (SDO), have spotted an unusual series of eruptions in which a series of fast 'puffs' force the slow ejection of a massive burst of plasma from the Sun's corona. The eruptions took place over a period of three days, starting on 17 January 2013. Images and animations of the phenomena were presented at the National Astronomy Meeting 2014 in Portsmouth by Nathalia Alzate on Monday 23...

3 x-class flares
2014-06-11 08:40:19

UPDATE - June 11, 2014 On June 11, 2014, the sun erupted with its third X-class flare in two days. The flare was classified as an X1.0 and it peaked at 5:06 a.m. EDT.  Images of the flare were captured by NASA's Solar Dynamics Observatory. All three flares originated from an active region on the sun that recently rotated into view over the left limb of the sun. ----- UPDATE - June 10: The sun released a second X-class flare, peaking at 8:52 a.m. EDT on June 10, 2014.  This is...

[ Watch the Video: The Best Observed X-Class Flare ] redOrbit Staff & Wire Reports - Your Universe Online An X-class solar flare that erupted on March 29 was observed by four different spacecraft and one ground-based observatory, making it the best viewed phenomenon of its kind, NASA officials announced on Wednesday. The intense flare, which originated from the right side of the sun, was detected and monitored by the Interface Region Imaging Spectrograph (IRIS), the Solar...

Karen C. Fox, NASA's Goddard Space Flight Center The sun emitted a significant solar flare, peaking at 8:27 p.m. EDT on April 24, 2014. Images of the flare were captured by NASA's Solar Dynamics Observatory. Solar flares are powerful bursts of radiation.

What's Lurking Beneath The Surface Of The Sun?
2014-04-21 12:49:25

NASA Like a balloon bobbing along in the air while tied to a child's hand, a tracer has been found in the sun's atmosphere to help track the flow of material coursing underneath the sun's surface. New research that uses data from NASA's Solar Dynamics Observatory, or SDO, to track bright points in the solar atmosphere and magnetic signatures on the sun's surface offers a way to probe the star's depths faster than ever before. The technique opens the door for near real-time mapping of...

Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
