Massive Ring Of Carbon Monoxide Discovered In Turbulent Comet Field
2014-03-07 10:10:00

[ Watch the Video: Colliding Comets Hint At Unseen Exoplanet ] Brett Smith for redOrbit.com - Your Universe Online NASA scientists have found evidence of a highly-turbulent comet field circling a star 63 light years from Earth. This cosmic shooting gallery has produced a massive ring of carbon monoxide gas and dust that also encircles the star, according to a new report published in the journal Science. According to the report authors, the comet field is probably the result of either...

Space Weather Shielding Provided By Plasma Plumes
2014-03-07 05:41:48

April Flowers for redOrbit.com - Your Universe Online The magnetosphere, Earth's magnetic field, stretches from the core of the planet out into space. Here, the magnetosphere meets the solar wind, a stream of charged particles emitted by the sun. The magnetosphere, for the main part, acts to shield the Earth from this high-energy solar activity. When the Earth's magnetosphere comes into contact with the sun's magnetic field in a process called "magnetic reconnection," the Earth's...

Small Asteroid Will Safely Pass Earth
2014-03-06 12:52:56

NASA's Jet Propulsion Laboratory An asteroid about 25 feet (8 meters) across will safely pass Earth at about 1:21 p.m. PST (4:21 p.m. EST) today, March 6, approaching us six times closer than the moon. This distance, though not unusual, is closer than the Earth flyby of a larger asteroid on Wednesday afternoon, March 5. This afternoon's flyby object, asteroid 2014 EC, was discovered on March 5 by the Catalina Sky Survey near Tucson, Ariz. Its closest-approach distance, about 38,300...

DAVIS, Calif., March 6, 2014 /PRNewswire-USNewswire/ -- "Soil health is a journey to understand how to mimic nature," says Ray 'the-Soil-Guy' Archuleta, a conservationist and soil health instructor with the USDA's Natural Resources Conservation Service (NRCS). Farmers and anyone who wants to understand how to build more naturally fertile soil that also absorbs rainfall while requiring fewer inputs to produce a profitable crop, are invited to attend any of the four free seminars. The...

Hubble Space Telescope Catches Asteroid Breaking Up Due To Sunlight
2014-03-06 12:11:47

[ Watch the Video: The Breakup of Asteroid P/2013 R3 ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers publishing a paper in the Astrophysical Journal Letters say they witnessed an asteroid breakup into as many as 10 smaller pieces. The team used NASA/ESA's Hubble Space Telescope to photograph the asteroid as it shredded when nearing the sun. "Seeing this rock fall apart before our eyes is pretty amazing," David Jewitt, a professor in the UCLA Department of Earth,...

redOrbit Staff & Wire Reports - Your Universe Online A team of researchers from the University of Arizona’s Department of Astronomy have managed to use an Earth-based telescope to capture images of a world outside of our solar system, according to research scheduled to be published in an upcoming edition of The Astrophysical Journal. The telescope used essentially the same type of imaging sensor found in a standard digital camera instead of an infrared detector, and while the...

Jupiter Moon Mission Planned By NASA
2014-03-05 14:19:48

Lee Rannals for redOrbit.com - Your Universe Online NASA is developing a new mission for 2015 that would send a spacecraft to Jupiter’s moon Europa to investigate whether the moon contains conditions suitable for life. Europa is an icy moon that scientists believe could hold an ocean of liquid water beneath its icy crust. If an ocean can be found underneath Europa’s crust, it means the moon could have conditions favorable for life. Essentially, where there is water there is a...

Exoplanet Atmospheres

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The holy grail of planetary astronomy is the search for a potentially habitable planet, or even better, one that is shown to already contain life. There are various parameters that are needed in order to ascertain the habitability of worlds, such as whether liquid water can be sustained on its surface. Recent studies, however, have found that identifying some of these characteristics is rather difficult, and we may in fact...

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...
