Protecting Spacecraft From Space Junk
2013-06-27 16:16:45

Lee Rannals for redOrbit.com - Your Universe Online Researchers developed a numerical algorithm that simulates the shock of orbital debris striking materials that make up a space vehicle's outer defense. Scientists commonly use supercomputers to investigate physical phenomenon that cannot be duplicated in a laboratory environment. By running simulations on these such computers, University of Texas researchers have assisted NASA in the development of ballistic limit curves that predict...

NASA’s IRIS Solar Mission Launch Moved To Thursday
2013-06-25 03:10:20

[ Watch the video IRIS Science Overview ] Lee Rannals for redOrbit.com - Your Universe Online Update (June 25, 2013 3:10 p.m.) NASA announced on Tuesday that its planned launch for its Interface Region Imaging Spectrograph (IRIS) mission has been moved due to the "recent central California power outage." The launch window has moved from Wednesday, June 26 to Thursday, June 27. Stay tuned for further updates. Main Story (June 24, 2013 12:43 p.m.) NASA's Interface...

M5.9 Solar Flare Emitted By The Sun
2013-06-11 09:18:19

NASA The sun emitted a mid-level solar flare, peaking at 6:49 p.m. on June 7, 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 communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, anywhere from minutes to hours. This flare is classified as an...

Magnetic Field Model Of Sun Explains Solar Activity Cycles
2013-05-23 08:32:58

April Flowers for redOrbit.com - Your Universe Online Since the 18th Century, scientists have been aware that the Sun oscillates between periods of high and low solar activity in an 11-year cycle. So far, though, they have been unable to fully explain how this cycle is generated. Understanding the Sun´s magnetic activity has become increasingly important as we rely more on our electronic devices. Changes in the magnetic field are responsible for “space weather”...

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...

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...

Planetary and Space Science
2012-05-28 10:21:45

Planetary and Space Science is a peer-reviewed scientific journal established in 1959 and published by Elsevier 15 times per year. As of May 2012, the editor-in-chief is Rita Schulz (The Netherlands). The journal publishes original research articles and short communications. The main focus is on solar system processes which encompass multiple areas of the natural sciences. Research that involves planetary and space sciences involves many disciplines. 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...

monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
