Meteorite violent origins
2014-08-09 05:13:23

April Flowers for redOrbit.com - Your Universe Online Seven years ago, the Bunburra Rockhole Meteorite fell on the Western Australia (WA) side of Nullarbor Plain and was captured on camera. A new study, published in Geochimica and Cosmochimica Acta, indicates that the unique characteristics of the meteorite suggest it originates from a never-before-identified asteroid. The research team — comprised of Curtain University's Associate Professor Fred Jourdan, Professor Phil Bland and Dr....

Cassini spacecraft

Preston Dyches, NASA Jet Propulsion Laboratory NASA's Cassini spacecraft will execute the largest planned maneuver of the spacecraft's remaining mission on Saturday, Aug. 9. The maneuver will target Cassini toward an Aug. 21 encounter with Saturn's largest moon, Titan. The main engine firing will last about a minute and will provide a change in velocity of 41 feet per second (12.5 meters per second). This is the largest maneuver by Cassini in five years. No other remaining maneuver...

Companion planets
2014-08-02 04:44:52

April Flowers for redOrbit.com - Your Universe Online For humans, having a companion in our later years can help increase our lifespan. A new study led by the University of Washington shows that having a companion might also extend the life of some Earth-sized planets. As a planet ages, it cools and the molten core solidifies. This leads to a dwindling of the inner heat-generating activity that keeps the planet habitable by regulating carbon dioxide to prevent runaway heating and...

mercury magnetic field
2014-08-01 03:45:58

Stuart Wolpert, University of California - Los Angeles Earth and Mercury are both rocky planets with iron cores, but Mercury's interior differs from Earth's in a way that explains why the planet has such a bizarre magnetic field, UCLA planetary physicists and colleagues report. Measurements from NASA's Messenger spacecraft have revealed that Mercury's magnetic field is approximately three times stronger at its northern hemisphere than its southern one. In the current research,...

artistic conception of the early Earth
2014-08-01 04:33:08

redOrbit Staff & Wire Reports - Your Universe Online Over four billion years ago, giant asteroid impacts collided with the Earth’s surface and gave the planet a facelift of sorts – mixing, burying and melting the landscape, according to a new terrestrial bombardment model devised by an international team of researchers from various academic and government institutions. The new model was based on existing lunar and terrestrial data, and according to the authors of a new paper...

redOrbit Staff & Wire Reports - Your Universe Online More than four decades after US astronauts first visited the lunar surface, scientists have finally determined both the actual shape of the moon and the forces responsible for giving it that form, according to a new study published this week in the journal Nature. As it turns out, the moon is somewhat flattened with a bulge on one side, the authors told Douglas Quenqua of the New York Times. University of California, Santa Cruz...

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...
