Atmospheric Drag Impacts On Satellite Orbits
2013-09-12 04:13:35

redOrbit Staff & Wire Reports - Your Universe Online A beach ball-sized satellite designed to investigate the impact that atmospheric drag can have on satellite orbits is slated to be launched by NASA on Sunday, September 15. The satellite, which is known as the Drag and Atmospheric Neutral Density Explorer (DANDE), was designed and built by students at the University of Colorado Boulder. It will depart from Vandenberg Air Force Base in California and be carried into space aboard a...

No Planetary Influence On Solar Activity
2013-09-05 14:37:53

Lee Rannals for redOrbit.com - Your Universe Online New research in Astronomy & Astrophysics (A&A) is correcting errors in one statistical study published in the same journal last yea,r regarding the isotopic records of solar activity. Last year, astronomers wrote in the journal claiming that there is evidence of planetary influence on solar activity. However, the latest study refutes that claim, saying that they found no evidence of any planetary effect on the Sun. The Sun...

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...

Solar Flip Soon
2013-08-06 13:41:02

Brett Smith for redOrbit.com - Your Universe Online [ Watch the Video: Preparing For The Solar Max Magnetic Flip ] Solar experts are anticipating a major event that is about to happen within the next three or four months - the sun is going to flip. Every eleven years, the Sun reaches the peak of its cycle and proceeds to switch polarity, making north become south and south become north. NASA scientists said the upcoming change will also mark the halfway point of solar max, a period...

Asteroid Grand Challenge First Round Reviews Complete
2013-08-01 04:35:09

April Flowers for redOrbit.com - Your Universe Online The first step toward NASA's mission to find and capture a near-Earth asteroid, redirect it to a stable Earth-lunar orbit, and send humans to examine it, has been completed. On Tuesday, a mission formulation review brought together NASA leaders from around the US to examine internal studies proposing multiple concepts and alternatives for each phase of the asteroid mission in preparation for fiscal year 2014. Technical and...

NASA [ Watch the Video GOES-R Magnetometer Boom Deployment] The GOES-R Magnetometer Engineering Development Unit made an important development in the construction of the spacecraft recently after completing a successful boom deployment test at an ATK facility in Goleta, Calif. The Geostationary Operational Environmental Satellite -- R Series advanced spacecraft and instrument technology will result in more timely and accurate weather forecasts. It will improve support for the...

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...

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...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
