Solar Winds Affect Earth's Magnetosphere
2012-08-01 13:04:29

April Flowers for redOrbit.com — Your Universe Online Weather has always affected our lives, but we are increasingly reliant on technology that can be disrupted by space weather. Geomagnetic storms, which are major disturbances of the magnetosphere, cause high altitude flights to be rerouted, costing many thousands of dollars per flight; cause GPS errors of up to 151 feet; and affect the International Space Station and satellites. Geomagnetic storms and other space weather...

Solar Flare Captured By SDO
2012-07-31 13:47:29

Lee Rannals for redOrbit.com - Your Universe Online NASA's Solar Dynamics Observatory (Solar Dynamics Observatory) captured a mid-level solar flare on Saturday, showing us that the sun is getting prepped for its solar maximum. SDO witnessed the image on the active region of the sun named AR 1532 in the 131 Angstrom wavelength. This wavelength is typically colorized as teal, and is particularly good for catching flares, NASA said. Solar flares emit powerful bursts of radiation, which...

Coronal Mass Ejection Unlikely To Reach Earth
2012-07-21 04:31:52

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online A coronal mass ejection (CME) associated with a solar flare emitted early Thursday morning is unlikely to reach Earth, but it could affect one of the two Solar Terrestrial Relations Observatory (STEREO) satellites currently orbiting the sun, NASA officials posted on the agency's official website. According to the US space agency, the sun emitted a mid-level (M7.7) flare on July 19. The flare, which began at...

Solar Storm Expected To Reach Earth Saturday Morning
2012-07-14 04:10:29

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online A solar storm, scheduled to arrive Saturday morning and last through the end of the day on Sunday, is expected to put on a show for sky-gazers but should otherwise have little to no effect, according to scientists. According to the Associated Press (AP), the storm began on Thursday, as the sun unleashed a powerful solar flare -- the sixth recorded by scientists this year. The NOAA Space Weather Prediction...

Star Cluster Could Help Astronomers Find Earth-Like Planets
2012-06-23 06:15:20

A loose star cluster located approximately 800 to 1,000 light years from Earth, detected by scientists more than 180 years ago but never analyzed in detail, could be vital in helping experts not only to understand how stars like the Sun evolve, but also to help them in the search for Earth-like planets. According to a June 22 press release, researchers from Penn State University and colleagues from the University of California, Santa Cruz (UCSC); Yale University; and the California...

Euclid Receives Big Money Bump By U.K. Space Agency
2012-06-21 04:40:39

Lee Rannals for redOrbit.com United Kingdom scientists have been given a $13 million grant by the U.K. Space Agency to build the Euclid satellite to study the "dark Universe." Physicists and engineers have been working on getting the Euclid mission up into space by the end of this decade to study the enigmatic dark matter and dark energy. The additional investment by the U.K. Space Agency will help get the Euclid project to its end goal. The Euclid Consortium is made up of nearly...

More atomic hydrogen gas – the ultimate fuel for stars – is lurking in today´s Universe than we thought, CSIRO astronomer Dr Robert Braun has found. This is the first accurate measurement of this gas in galaxies close to our own. Just after the Big Bang the Universe´s matter was almost entirely hydrogen atoms. Over time this gas of atoms came together and generated galaxies, stars and planets – and the process is still going on. Astronomers want to understand...

Missing Mass: Lone Wolf Planets Outnumber Milky Way Stars
2012-05-11 03:16:53

Researchers say life-bearing planets may exist in vast numbers in the space between stars in the Milky Way A few hundred thousand billion free-floating life-bearing Earth-sized planets may exist in the space between stars in the Milky Way. So argues an international team of scientists led by Professor Chandra Wickramasinghe, Director of the Buckingham Centre for Astrobiology at the University of Buckingham, UK. Their findings are published online in the Springer journal Astrophysics and...

Medium-Class Solar Flare Erupts On Tuesday
2012-05-08 10:14:19

Lee Rannals for RedOrbit.com [ Watch the Video ] A medium-class solar flare erupted from the Sun on Tuesday, prompting scientists to keep their eye on the region for a space weather impact on Earth. NASA said its Solar Dynamics Observatory (http://www.nasa.gov/mission_pages/sdo/main/index.html) caught the Sun pumping out an M1.4-class solar flare on the large active region 1476. According to the space agency, the images seen by SDO unveil temperatures of around 10 million degrees...

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...
