Aurora Illuminates Sky Near Tromsø, Norway
2013-04-15 10:19:28

ESA These colorful displays are produced when electrically charged particles traveling from the Sun in the solar wind are channeled along Earth´s magnetic field lines and strike atoms high in the atmosphere. Collisions with oxygen atoms typically generate green aurora, as seen here. The link between auroras and solar activity has been apparent for centuries, but only with the aid of satellites can scientists begin to decipher the physical mechanisms causing this spectacular...

Project Analyzing Impact Of Space Weather On Satellites Gets NASA Grants
2013-04-14 07:18:25

redOrbit Staff & Wire Reports — Your Universe Online The University of Central Florida (UCF) has received a $55 million grant from NASA toward the development and operation of an instrument that will investigate the impact of space weather on orbiting communication and navigation satellites, the Orlando-based institution announced Friday. The mission is known as the Global-scale Observations of the Limb and Disk (GOLD) project, and it will monitor Earth´s upper...

Mid-Level Flare Emitted By The Sun
2013-04-11 14:08:16

NASA The M6.5 flare on the morning of April 11, 2013, was also associated with an Earth-directed coronal mass ejection (CME), another solar phenomenon that can send billions of tons of solar particles into space and can reach Earth one to three days later. CMEs can affect electronic systems in satellites and on the ground. Experimental NASA research models show that the CME began at 3:36 a.m. EDT on April 11, leaving the sun at over 600 miles per second. Earth-directed CMEs can cause a...

ESA Opens New Space Weather Center In Brussels To Keep Their Eyes On Our Sun
2013-04-05 13:48:27

ESA This week, ESA opened a new Space Weather Coordination Centre to gather up-to-date information on our Sun. It is the first such data coordination center opened under the Agency´s Space Situational Awareness Programme. The new Space Situational Awareness (SSA) Space Weather Coordination Centre (SSCC) will serve as the central access point to a portfolio of European space-weather expertise for customers, including satellite operators, industrial sectors including...

Noctilucent Clouds Observed By NASA Sounding Rocket
2013-04-04 14:55:35

NASA A constant stream of space debris flows toward Earth from the rest of the solar system. Large meteors can sometimes survive the intense friction and heat upon entering Earth´s atmosphere, but by and large the meteors evaporate and reform into tiny particles that are left to whiz through the atmosphere. Such particles are so light and so ubiquitous that scientists refer to them as smoke. Tracking how this smoke swirls around Earth has implications for understanding weather and...

Powerful Coronal Mass Ejection Erupts On Sun's Earth-Facing Side
2013-03-15 13:42:58

Lawrence LeBlond for redOrbit.com - Your Universe Online A powerful solar eruption occurred on the surface of the sun at 2:54 a.m. (EDT) this morning. The eruption, called a coronal mass ejection (CME), occurred on the Earth-facing side of the sun and may have released billions of tons of solar particles into space racing their way toward Earth, potentially making impact within three days. Once particles from this CME event hit Earth, electrical systems in orbit, in the sky and on...

Sun Erupts With Two CMEs In One Day
2013-03-14 14:15:10

Brett Smith for redOrbit.com - Your Universe Online Earlier this week the sun twice ejected large amounts of solar material during two coronal mass ejections (CMEs) in a 12-hour period, according to a NASA report. The CMEs are not expected to significantly impact Earth. The first CME began at 8:36 p.m. EDT on March 12, 2013. The solar material was directed toward three NASA spacecraft, Spitzer, Kepler and Epoxi. Two of the crafts, Spitzer and Kepler, are in an Earth-like orbit around...

New Satellite Will Provide Earlier Storm Warnings And Space Weather Predictions
2013-03-03 06:04:44

[ Watch the Video: Talking Tornadoes with Tim Samaras ] Alan McStravick for redOrbit.com - Your Universe Online On December 26, 2004, we learned of the importance that early warning systems can play in preventing loss of life when the great Indonesian tsunami caught locals and vacationers alike by surprise. In contrast, on March 11, 2011, the early warning system, while unable to prevent tens of thousands of human casualties, was effectively responsible for preventing a greater loss of...

Van Allen Probes Discover New Radiation Belt, Possibly Due To Solar Storm
2013-02-28 14:59:50

Lee Rannals for redOrbit.com — Your Universe Online NASA announced that its Van Allen Probes have led to a revision of a 50-year-old theory about the Earth's radiation belts. The Van Allen radiation belts surrounding Earth were thought to be just two giant swaths of radiation, first discovered in 1958. More than a half-century later, NASA launched twin probes (August 30, 2012) to create a detailed map of the region and catalogue a variety of energies and particles in these...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
