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 Planetary Society Conditionally Supports NASA's Asteroid Mission
2013-05-16 09:59:44

The Planetary Society NASA's asteroid mission could represent a new milestone in humanity's presence in and influence on the Solar System. For the first time in history, we would capture an entire object in orbit around the Sun and move it to a place of our choosing. We would evolve from mere observers of the motions of the heavens to participants in determining them. The Planetary Society conditionally supports NASA's plan to capture a small asteroid and place it in lunar orbit. In the...

Solar Activity Continues On The Sun
2013-05-15 11:28:59

NASA Solar activity continued on May 14, 2013, as the sun emitted a fourth X-class flare from its upper left limb, peaking at 9:48 p.m. EDT. This flare is classified as an X1.2 flare and it is the 18th X-class flare of the current solar cycle. The flare caused a radio blackout — categorized as an R3, or strong, on NOAA´s space weather scales from R1 to R5 -- which has since subsided. The flare was also associated with a non-Earth-directed CME. CMEs and flares are separate but...

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...

Engineering Control Designed to Protect Against Carbon Nanotubes and Nanofibers FREDERICA, Del., May 7, 2013 /PRNewswire/ -- ILC Dover, the designer and manufacturer of NASA's space suits and a wide range of engineered film and fabric products, announced its innovative NanoPac(TM) flexible containment system, which exceeds new NIOSH (National Institute for Occupational Safety) standards for nanoparticle containment. As nanotechnology continues to expand into every industrial...

Mid-Level Solar Flare Emitted By The Sun
2013-05-04 08:29:41

NASA The sun emitted a mid-level solar flare, peaking at 1:32 pm EDT on May 3, 2013. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, and the radio blackout for this flare has already...

Satellite Instrument Package To Assess Space Weather Ready For Delivery
2013-05-02 15:25:32

University of Colorado Boulder A multimillion dollar University of Colorado Boulder instrument package to study space weather has passed its pre-installation testing and is ready to be incorporated onto a National Oceanic and Atmospheric Administration satellite for a 2015 launch. Designed and built by CU´s Laboratory for Atmospheric and Space Physics, the instrument suite known as the Extreme Ultraviolet and X-ray Irradiance Sensors, or EXIS, is the first of four identical...

Orbital To Build Icon Space Weather Satellite For NASA
2013-04-30 04:53:34

redOrbit Staff & Wire Reports - Your Universe Online NASA has awarded a two-year, $50 million contract to Orbital Sciences Corporation to build a new heliophysics science satellite that will investigate the connection between space weather storms in the ionosphere and Earth´s terrestrial weather. The mission is currently set to launch in 2017, and will study the interface between the upper reaches of the Earth´s atmosphere and outer space in response to a recent scientific...

NASA Mission To Study What Interferes With Radio Waves
2013-04-26 07:44:43

NASA A NASA-funded sounding rocket mission will launch from an atoll in the Pacific in the next few weeks to help scientists better understand and predict the electrical storms in Earth's upper atmosphere. These storms can interfere with satellite communication and global positioning signals. The mission, called EVEX, for the Equatorial Vortex Experiment, will launch two rockets for a twelve-minute journey through the equatorial ionosphere above the South Pacific. The launch window for...

Stellar Astrophysics

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

Celestial mechanics is part of these...

Ring Current
2004-10-19 04:45:44

Ring Current -- A ring current is an electric current carried by charged particles trapped in a planet's magnetosphere. It is caused by the longitudinal drift of energetic (10-200 keV) particles. Earth's Ring Current Earth's ring current is responsible for geomagnetic storms. The ring current system consists of a band, at a distance of 3-5 RE(1), which lies in the equatorial plane and circulates clockwise around the Earth (when viewed from the north). The particles of this region...

Planetary Ring -- A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. The most spectacular and famous planetary rings are those around Saturn, but all four of the solar system's gas giant planets (Jupiter, Saturn, Uranus, Neptune) possess ring systems of their own. The origin of planetary rings is not precisely known, but they are thought to be unstable and dissipate over the course of tens or hundreds of millions of...
