Solar Spacecraft Celebrate Six Years In Service
2012-10-29 03:50:29

redOrbit Staff & Wire Reports - Your Universe Online On Thursday, October 25, NASA's twin Solar Terrestrial Relations Observatory (STEREO) program celebrated its sixth anniversary orbiting the sun, the US space agency announced on Friday. The twin orbiting probes were launched on that date in 2006, and ultimately entered into similar but separate orbits around the sun. STEREO-A's orbit is slightly smaller and faster, while STEREO-B's is larger and slower, they said, and those subtle...

The Song Of The Earth Captured And Sampled By Twin NASA Spacecraft
2012-10-01 07:53:45

[Watch The Video] [Listen to EarthSong] Lawrence LeBlond for redOrbit.com - Your Universe Online Earth is filled with many sounds and no matter where you go it is inescapable. From the roar of the city streets, to the ever-pleasing sounds of nature, and the endless commotion of human chatter. But there is one sound that most of us have never heard: the sound of the Earth itself. The sound (or song) is called “chorus,” explains Craig Kletzing of the University of Iowa....

The Moon In 3D
2012-09-25 13:22:59

Lee Rannals for redOrbit.com - Your Universe Online Scientists are using data from NASA's Lunar Reconnaissance Orbiter (LRO) to develop a way to explore the Moon in three dimensions. The team used images taken from different angles and were able to generate rich 3D maps of the surface of the Moon. The way a human brain deciphers three dimensions is that our eyes are slightly apart, and are able to see the world at separate angles at the same time. The human brain is able to interpret...

Astronomers Look Long At Coronal Mass Ejections
2012-09-20 18:54:36

Lee Rannals for redOrbit.com — Your Universe Online Astronomers reported in The Astrophysical Journal they have a better understanding of the temperatures of the coronal cavities in Coronal Mass Ejections (CMEs). Terry Kucera, a solar scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, along with colleagues, set out to understand the structure of CMEs, even before they erupt. CMEs are eruptions that take place on the sun that can travel toward Earth and...

Fastest Coronal Mass Ejection Observed By STEREO

[ Watch the Video: STEREO Captures Fastest CME to Date ] Lee Rannals for redOrbit.com - Your Universe Online NASA's STEREO spacecraft has observed the fastest coronal mass ejection (CME) ever seen on the Sun. The Solar TErrestrial RElations Observatory (STEREO) clocked the massive eruption traveling between 1,800 and 2,000 miles per second as it ejected from the sun. NASA said this was the fastest CME ever observed by STEREO, which launched back in 2006. "Between 1,800 and...

Coronal Mass Ejection Unlikely To Reach Earth
2012-07-21 04:31:52

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online A coronal mass ejection (CME) associated with a solar flare emitted early Thursday morning is unlikely to reach Earth, but it could affect one of the two Solar Terrestrial Relations Observatory (STEREO) satellites currently orbiting the sun, NASA officials posted on the agency's official website. According to the US space agency, the sun emitted a mid-level (M7.7) flare on July 19. The flare, which began at...

With the moon as the most prominent object in the night sky and a major source of an invisible pull that creates ocean tides, many ancient cultures thought it could also affect our health or state of mind — the word "lunacy" has its origin in this belief. Now, a powerful combination of spacecraft and computer simulations is revealing that the moon does indeed have a far-reaching, invisible influence — not on us, but on the Sun, or more specifically, the solar wind. The solar...

[ Watch the Video ] One day in the fall of 2011, Neil Sheeley, a solar scientist at the Naval Research Laboratory in Washington, D.C., did what he always does — look through the daily images of the sun from NASA's Solar Dynamics Observatory (SDO). But on this day he saw something he'd never noticed before: a pattern of cells with bright centers and dark boundaries occurring in the sun's atmosphere, the corona. These cells looked somewhat like a cell pattern that occurs on the...
