NASA Sun Observer Captures Two Solar Eruptions Over Four Hours
2012-11-17 15:28:22

[ Watch the Video: Double Prominence Eruptions ] Lawrence LeBlond for redOrbit.com - Your Universe Online On November 13, the Sun emitted an M6 classification solar flare, one of the weakest designations still able to cause some disturbances on Earth. Now, just a few days later, the Sun is at it again. NASA´s Solar Dynamic Observatory (SDO) caught spectacular images and video of the Sun bursting with two prominence eruptions over a four-hour period on November 16, between the...

GREENBELT, Md., Nov. 16, 2012 /PRNewswire-USNewswire/ -- A remote sensing instrument that will peer into the ultraviolet to offer clues to how Mars might have lost its atmosphere has arrived at Lockheed Martin for integration into NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) "The Remote Sensing package team built a system that meets all technical requirements and delivered it on schedule and on budget," said...

NASA Observatory Captures Another X-Class Solar Flare
2012-10-23 15:32:34

[WATCH VIDEO: Active Region On The Sun Emits Another Flare] Lee Rannals for redOrbit.com — Your Universe Online NASA said its Solar Dynamics Observatory (SDO) captured the sun erupting with an X1.8 class solar flare on Monday. The solar flare came from an active region on the left side of the sun known as AR 1598, which has been the source of weaker flares. The "X-class" solar flares are the most intense flares, with the number near the X representing its intensity. An X2...

Solar Plasma Wave Unleashed
2012-10-21 08:45:32

April Flowers for redOrbit.com - Your Universe Online NASA´s Solar Dynamics Observatory captured a spectacular solar eruption on Friday. A giant super-hot wave of solar plasma larger than the planet Earth erupted from the Sun at 4:15 a.m. EDT and was caught in amazing high-definition detail by the NASA spacecraft. "Once it started breaking away, the process only took 10 hours before it was out of sight," NASA media specialist Steele Hill explained in a photo description. "The...

NASA Team Overcoming Image Degradation
2012-10-06 09:34:41

redOrbit Staff & Wire Reports — Your Universe Online A NASA satellite studying the sun saw its view obstructed by Earth for a brief period of time each day throughout much of the month of September. Those eclipses had an unusual effect on the images captured by the probe immediately afterwards, the U.S. space agency revealed on Friday. NASA's Solar Dynamics Observatory (SDO) moved into what is known as its semi-annual eclipse phase from September 6 through September 29,...

Radiation From Sun’s Solar Whip Is Expected To Reach Earth Today
2012-09-04 07:45:16

Watch the Video: Filament Eruption August 31, 2012 Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists from NASA have discovered an enormous ℠solar whip´ on the surface of the Sun and have warned that radiation from the phenomenon is heading straight toward Earth, arriving on our doorstep sometime today. The stunning event was captured by NASA´s Solar Dynamics Observatory (SDO) and, according to a report from Mail Online´s Mark Prigg, video and...

IDEA! Coronal Mass Ejection From The Sun
2012-08-28 14:51:12

Watch the Video: Lightbulb Shaped CME Lee Rannals for redOrbit.com - Your Universe Online The sun sent off another coronal mass ejection (CME) last week, but this time the plasma burst showed up in the form of a light bulb. The Solar and Heliospheric Observatory (SOHO) caught the CME light bulb with its Large Angle and Spectrometric Coronagraph (LASCO) C2 instrument. This instrument is able to take images of the solar corona by blocking the light coming directly from the Sun with...

Why Is The Sun So Perfectly Round?
2012-08-17 07:40:10

April Flowers for redOrbit.com - Your Universe Online On a summer's day, the sun dominates the sky looking for all the world like a big, round ball of light. Round is exactly what it is, it turns out. It is nearly the roundest object ever measured, according to a study from the University of Hawaii's Institute for Astronomy. If you scaled the sun down to the size of a beach ball, it would be so round that the difference between the widest and narrowest diameters would be much less than...

Solar Flare Captured By SDO
2012-07-31 13:47:29

Lee Rannals for redOrbit.com - Your Universe Online NASA's Solar Dynamics Observatory (Solar Dynamics Observatory) captured a mid-level solar flare on Saturday, showing us that the sun is getting prepped for its solar maximum. SDO witnessed the image on the active region of the sun named AR 1532 in the 131 Angstrom wavelength. This wavelength is typically colorized as teal, and is particularly good for catching flares, NASA said. Solar flares emit powerful bursts of radiation, which...

Solar Corona Captured In Highest Resolution Ever
2012-07-21 05:29:44

[ Video 1 ] | [ Video 2 ] redOrbit Staff & Wire Reports - Your Universe Online A telescope launched on board a NASA sounding rocket earlier this month has captured the highest-resolution images of the sun's corona, the US space agency announced on Friday. The 16-megapixel images of the million-degree atmosphere of the sun were captured in an extreme-ultraviolet wavelength of light by the High Resolution Coronal Images (Hi-C) telescope, according to the Harvard-Smithsonian Center...
