Latest Coronal mass ejection Stories

2013-07-11 16:18:48

On July 9, 2013, at 11:09 a.m. EDT, the sun erupted with an Earth-directed coronal mass ejection or CME, a solar phenomenon that can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground. Experimental NASA research models, based on observations from NASA’s Solar Terrestrial Relations...

Solar Tsunami Measures Sun Magnetic Field
2013-07-11 12:19:51

Lee Rannals for redOrbit.com - Your Universe Online A solar tsunami has provided scientists with the first accurate estimates of the Sun's magnetic field. Researchers wrote in the journal Solar Physics that solar tsunamis are produced by enormous explosions in the Sun's atmosphere known as coronal mass ejections (CMEs). As these events move through space, the tsunami travels across the Sun at speeds of up to 621 miles per second. Solar tsunamis have a higher speed in regions where the...

Space Weather Prediction Systems Need To Be More Reliable
2013-07-06 04:29:18

John P. Millis, Ph.D. for redOrbit.com – Your Universe Online The residents of Earth have a vested interest in being able to accurately predict solar activity, particularly events such as solar flares and coronal mass ejections (CMEs). These eruptions spew energetic charged particles into the solar system at fantastic rates, which have the potential to damage orbiting satellites and even ground based power grids. Our first line of defense against solar activity is knowing when to...

Fascinating Features On Sun Captured By Solar Dynamics Observatory
2013-07-05 13:32:39

Lee Rannals for redOrbit.com - Your Universe Online Scientists studying the solar atmosphere have spotted some fascinating moving features in the Sun's sky. A team using the Atmospheric Imaging Assembly (AIA) telescope on board the Solar Dynamics Observatory (SDO) satellite has found unusual solar prominences, including: a giant disc that rotates for several hours; feathery streams as long as fifty Earths; a super-heated jet striking the top of a prominence; and twisted ribbons flowing...

Scientists Study Coronal Loops To Gain Insight Into Solar Dynamics
2013-07-02 18:21:44

John P. Mills, Ph.D. for redOrbit.com -- Your Universe Online Solar flares and the even more violent Coronal Mass Ejections (CMEs) are spectacular events, driving enormous amounts of energy and streams of charged particles into space. While researchers have had the opportunity to study these events for decades, we are still learning about what initiates these explosions. Previous studies have revealed that twisted magnetic field lines within the solar structure will pierce the surface...

CME Headed Toward Mercury And Venus
2013-07-02 16:01:43

NASA On July 1, 2013, at 6:09 p.m. EDT, the sun erupted with a coronal mass ejection, or CME, a solar phenomenon that can send billions of tons of solar particles into space that can affect electronic systems in satellites. Experimental NASA research models based on NASA's Solar Terrestrial Relations Observatory show that the CME was not Earth-directed and it left the sun at around 570 miles per second. The CME may, however, pass by NASA's Messenger, Spitzer and STEREO-B satellites, and...

New Program Aims To Understand Effects Of Space Weather
2013-07-01 19:10:36

Lee Rannals for redOrbit.com -- Your Universe Online Scientists are working on a program to better understand how national grids could be affected by space weather. British Geological Survey (BGS) researchers are conducting continuous measurements of the background electric field in the UK to better understand how the UK National Grid can be interrupted by the Sun. Space weather can take place when the ejection of material from the Sun, or coronal mass ejection (CME), shoots towards...

M-Class Solar Flare And Two Coronal Mass Ejections Detected Mid-Week
2013-05-23 07:00:42

Lawrence LeBlond for redOrbit.com - Your Universe Online As the peak year of the solar maximum picks up in intensity, NASA´s Solar Dynamics Observatory (SDO) observed yet another solar flare and two coronal mass ejections (CMEs) mid-week. On Wednesday May 22 the sun emitted an M7 solar flare, which peaked at about 9:38 a.m. EDT. While it was not immediately clear if the M-class flare also produced a CME, NASA confirmed later that the flare was associated with a CME. While this CME...

Coronal Mass Ejection Heads Toward Earth This Weekend
2013-05-19 07:37:21

[WATCH VIDEO: Coronal Mass Ejection On May 17, 2013] Lawrence LeBlond for redOrbit.com - Your Universe Online On May 17, the sun unleashed an Earth-directed coronal mass ejection (CME) at 5:24 a.m. EDT sending billions of tons of solar particles into space. The matter from this CME will likely reach Earth in one to three days and potentially affect electronic systems in satellites and possibly the International Space Station (ISS). NASA research models based on observations from...

The Impacts Of Strong Solar Flares
2013-05-14 07:53:54

NASA Given a legitimate need to protect Earth from the most intense forms of space weather -- great bursts of electromagnetic energy and particles that can sometimes stream from the sun -- some people worry that a gigantic "killer solar flare" could hurl enough energy to destroy Earth, but this is not actually possible. Solar activity is indeed currently ramping up toward what is known as solar maximum, something that occurs approximately every 11 years. However, this same solar cycle...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
