Kathryn Hansen, NASA Ecologist Thomas Mueller uses satellite data to study how the patterns of plant growth relate to the movement of caribou and gazelle. The research sparked an idea: Would the footprint of human activity show up in the data? Mueller, of the University of Maryland in College Park (now at the Biodiversity and Climate Research Center in Frankfurt) teamed up with university and NASA colleagues to find out. Their new analysis shows that on a global scale, the presence of...

cassini grand finale
2014-07-01 06:45:49

Preston Dyches, NASA Jet Propulsion Laboratory With input from more than 2,000 members of the public, team members on NASA's Cassini mission to Saturn have chosen a name for the final phase of the mission: the Cassini Grand Finale. Starting in late 2016, the Cassini spacecraft will begin a daring set of orbits that is, in some ways, like a whole new mission. The spacecraft will repeatedly climb high above Saturn's north pole, flying just outside its narrow F ring. Cassini will probe the...

Potentially Habitable Exoplanet With Earth-Like Temperatures Found
2014-06-27 08:24:53

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have discovered a new, potentially habitable Super-Earth believed to possess temperatures comparable to those found here, but with much larger seasonal shifts, provided the atmosphere is similar to our planet's own. Dr. Robert A. Wittenmyer, a researcher at UNSW Australia specializing in the detection and characterization of extrasolar planets, and his colleagues located the new Super-Earth in orbit around the nearby...

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...

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...
