Gerard LeBlond for redOrbit.com - Your Universe Online [ Watch the Video: Plasma Simulation Of The Solar Wind And A Near-Earth Asteroid ] Space appears to be an endless vacuum void of sound, but it’s not. Electric activity not visible to the naked eye emerges from asteroids drifting through space, and NASA is now in the process of sending astronauts to an asteroid to explore its electrical environment. Solar winds from the sun travel through space about a million miles per hour and...

Astronomers Use AKARI Orbiting Observatory To Map Space’s Icy Wastes
2014-06-26 03:40:16

Royal Astronomical Society Using the AKARI orbiting observatory, astronomers from the Open University have made the first large-scale maps of icy material where stars are forming. In a challenge to conventional ideas about the formation of water in space, they find ice in regions with little dust or gas. Dr Helen Fraser, who led the new work, presented the results in her talk at the National Astronomy Meeting in Portsmouth this week. Launched by the Japanese space agency JAXA in 2006,...

Using A Telescope To Dig For Ice On Pluto
2014-06-26 03:59:09

Royal Astronomical Society In just over a year, the New Horizons spacecraft will fly past Pluto, giving us our first detailed look at the dwarf planet. Anticipating this encounter, St Andrews undergraduate student Ailsa Whitelaw and her supervisor Dr Jane Greaves have used forgotten data to map the sub-surface of Pluto, peering beneath its icy coating to uncover hidden chemicals that give a hint of the future of this distant world. Dr Greaves will present the new work in her talk on...

redOrbit Staff & Wire Reports - Your Universe Online [ Watch the Video: Cassini Saturn Arrival ] Monday, June 30 marks the 10th anniversary of the Cassini spacecraft’s arrival in the Saturn system, beginning a four-year primary mission that was extended on three occasions and ultimately led to the collection of more than 500 GB of data and the publication of well over 3,000 scientific papers. Cassini reached its destination on June 30, 2004, carrying with it the European Space...

Citizen Scientists Can Now Help Discover NEAs Using Asteroid Zoo
2014-06-25 09:09:37

Gerard LeBlond for redorbit.com - Your Universe Online Near-Earth Asteroids (NEAs) are space rocks that will pass close by our planet with a potential risk of impact. NASA, astronomers and scientists search the sky continually for these types of asteroids. Now, with the launch of Asteroid Zoo, the general public can assist in the search for undiscovered NEAs. Asteroid Zoo was launched on June 24, 2014 by Planetary Resources and Zooniverse allowing the general public, citizen scientists...

building blocks of comets
2014-06-24 08:52:55

Brett Smith for redOrbit.com - Your Universe Online A joint research effort between NASA and the European Space Agency has found proof that nitrogen within the atmosphere of Saturn's moon Titan came from conditions very similar to those that formed most of the ancient comets in the Oort cloud, according to a new report in the Astrophysical Journal Letters. The Oort cloud is a spherical cloud of predominantly icy space rocks believed to surround the Sun at a radius far outside the Solar...

Scientists Scratching Their Heads Over Titan's Vanishing 'Magic Island'
2014-06-23 10:52:26

Brett Smith for redOrbit.com - Your Universe Online A mysterious “island” that suddenly appeared and then disappeared on one of Saturn’s moons, as seen in NASA images, has scientists baffled. Dubbed the “Magic Island,” the feature on Titan, Saturn’s largest moon, showed up in an image captured by NASA's Cassini probe last year. Images of the same location captured nothing before or days after. According to a paper on the phenomenon published in Nature Geoscience, the...

Satellites Used To Watch For Shifting Land
2014-06-23 03:51:37

ESA Subsidence, rockfalls and landslides threaten potentially devastating human and economic consequences across Europe – but satellites can help. Traditional monitoring such as photographic mapping to measure changes in the landscape works well for specific locations but is labor intensive and costly. Now, ESA has looked at using satellites to watch for hazards across broad areas that could affect road and rail networks. The outcome is so promising that the resulting monitoring...

Swarm Shows Earth’s Changing Magnetism
2014-06-20 03:48:31

ESA The first set of high-resolution results from ESA’s three-satellite Swarm constellation reveals the most recent changes in the magnetic field that protects our planet. Launched in November 2013, Swarm is providing unprecedented insights into the complex workings of Earth’s magnetic field, which safeguards us from the bombarding cosmic radiation and charged particles. Measurements made over the past six months confirm the general trend of the field’s weakening, with the most...

Comet Siding Spring Won't Disrupt Martian Orbiters As It Makes Close Approach Of The Red Planet
2014-06-20 07:06:18

April Flowers for redOrbit.com - Your Universe Online Later this year, comet Siding Spring will have a very close brush with Mars. That brush will be so close, in fact, that it lead scientists to worry about the safety of the three spacecraft currently orbiting the planet. Some experts from the University of Maryland (UMD) have used a satellite mounted telescope to observe the "fresh" comet, however, and they find that it poses minimal danger to the Martian spacecraft. Instead, the...

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...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...
