Is The Solar Maximum Peak Upon Us? Increase In Sun's Activity May Tell
2013-10-26 08:22:09

[ Watch the Video: Our Sun Is Flaring Up ] Lawrence LeBlond for redOrbit.com - Your Universe Online Our sun, the bright yellow disk that sits at the center of the Solar System providing us with light, energy and warmth, has a much darker side that also has the potential to disrupt, rather than preserve, life on Earth. Experts know that the sun goes through a natural solar cycle about every 11 years, marked by an increase and decrease of sunspots – visible blemishes that appear on...

Third Solar Flare Emitted By The Sun In Two Days
2013-10-25 12:12:19

NASA [ Watch The Video: Experimental NASA Research Model of Path for Oct. 22-23 CMEs ] The M9.4 flare on Oct. 23, 2013, was associated with a 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. Another solar flare erupted from the same area...

Voyager 1 Has Left Solar System, Reaching New Horizons

[ Watch the Video: Are We There Yet? NASA Says Yes ] Lee Rannals for redOrbit.com - Your Universe Online Man has officially embarked on a new adventure that surpasses Lewis and Clark's excursion across the US, as NASA's Voyager 1 spacecraft officially reaches interstellar space. The US space agency announced on Thursday that after traveling through space for 36 years, the probe has finally ventured out into interstellar space, becoming the first man-made object to travel beyond our...

Another Earth-Directed Coronal Mass Ejection
2013-08-22 06:59:09

NASA On August 21, 2013 at 1:24 am 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 and 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 Observatory show...

NASA’s Solar Terrestrial Relations Observatory Sees An Earth Directed Coronal Mass Ejection

NASA On August 20, 2013 at 4:24 am EDT, the sun erupted with an Earth-directed coronal mass ejection or CME, a solar phenomenon which 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 Observatory...

Coronal Mass Ejection Witnessed By NASA's STEREO
2013-07-23 08:59:36

NASA On July 22, 2013, at 2:24 a.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 observations from NASA's Solar Terrestrial Relations Observatory, or STEREO, show that the CME was not Earth-directed, but may pass Mars.  It left the sun at around 715 miles per second, which is a fairly fast speed...

SOHO Video Shows Eruptions On Sun
2013-07-22 18:13:12

Lee Rannals for redOrbit.com - Your Universe Online A new video posted by the European Space Agency (ESA) shows two solar eruptions taking place side-by-side. The video, taken by ESA and NASA's Solar and Heliospheric Observatory (SOHO) on July 1 through 2 this year, shows two coronal mass ejections (CMEs) launching plasma into interplanetary space. CMEs are huge clouds of magnetized plasma ejecting from the Sun's atmosphere, which is known as the corona. These ejections comprise...

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...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
