In a world first, the sounds of Mars and Venus are revealed as part of a planetarium show in Hampshire this Easter. Despite many years of space exploration, we have no evidence of the sound of other planets. While most planetary probes have focused on imaging with cameras and radar and a couple have carried microphones, none of them successfully listened to the sound of another world. Now, a team from the University of Southampton, led by Professor Tim Leighton, has the answer. Using...

More than one billion stars in the Milky Way can be seen together in detail for the first time in an image captured by astronomers More than one billion stars in the Milky Way can be seen together in detail for the first time in an image captured by astronomers. Scientists created the color picture by combining infra-red light images from telescopes in the northern and southern hemispheres. Large structures of the Milky Way galaxy, such as gas and dust clouds where stars have formed and...

NASA Announces YouTube Space Lab Contest Winners
2012-03-23 04:04:11

NASA astronaut Suni Williams announced the winners of the YouTube Space Lab contest on Thursday. Dorothy Chen and Sara Ma from Troy, Michigan and Amr Mohamed from Egypt won the chance to see their science experiments performed on the International Space Station. Participants of the contest were asked to submit experiments that could be conducted in zero gravity by astronauts. Williams will be performing the two winning YouTube Space Lab contest experiments while on the Expedition 32...

Messenger Completes Mercury Mission
2012-03-21 12:30:58

In Roman mythology Mercury was the “Messenger of the Gods,” — as well as a god of trade, thieves and travel. It is thus fitting — apart from the trade and thieves aspect — that the MESSENGER program has been so carefully studying the inner most planet in our solar system. MErcury, Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) this week successfully completed a year-long mission to perform the first complete reconnaissance of the...

Solar Storm Threat Appears To Have Passed

[ Watch the Solar Flare in Action Here and Here ] Two recent Coronal Mass Ejections (CMEs) -- massive bursts of solar wind produced by the Sun -- appear to have caused little or no damage to electrical systems, according to scientists. The CMEs were caught by NASA as they took off from the Sun, traveling faster than 1,300 miles per second. The first wave hit yesterday morning, March 8. The second hit late last night into early this morning. Joseph Kunches, a scientist with the...

CMEs Heading Towards Earth
2012-03-07 15:15:46

[ Watch the Solar Flare in Action Here and Here ] NASA said on Wednesday that two Coronal Mass Ejections (CMEs) are now traveling faster than 1,300 miles per second, on track towards Earth. NASA's Solar Terrestrial Relations Observatory (STEREO) and the Solar Heliospheric Observatory (SOHO) caught the CMEs as they took-off from the sun. The space agency said the first CME, which is traveling at about 1,300 miles per second, will reach Earth on the morning of March 8. This CME...

A New Take On Planetary Accretion
2012-02-29 09:39:21

The prevailing model for planetary accretion, also called fractal assembly, and dating back as far as the 18th century, assumes that the Solar System´s planets grew as small grains colliding chaotically, coalescing into bigger ones, colliding yet more until they formed planetesimals. The planetesimals then collided until they formed planets as varied as the Earth and Jupiter. The model assumes that this occurred in an extremely hot (as high as 1,600 degrees Celsius) environment for...

Earth Siblings Can Be Different

Chemical clues on the formation of planetary systems The study of the photospheric stellar abundances of the planet-host stars is the key to understanding how protoplanets form, as well as which protoplanetary clouds evolve planets and which do not. These studies, which have important implications for models of giant planet formation and evolution, also help us to investigate the internal and atmospheric structure and composition of extrasolar planets.. Theoretical studies suggest that...

The geographical sciences website EurekaMag.com publishes insights into specific subjects of all areas of geographical science. The latest review covers Aurora borealis which are the Northern Lights caused by radiation emitted as light from atoms in the upper atmosphere as they are hit by fast-moving electrons and protons. Two other newly published reviews cover Solar Flare which is a large energy release at the sun's surface, and Solar Storm which is a massive burst of solar wind associated...

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...
