Two dynamos drive Jupiter's magnetic field
(Phys.org) —Superlatives are the trademark of the planet Jupiter. The magnetic field at the top edge of the cloud surrounding the largest member of the solar system is around ten times stronger than Earth's, and is by far ...
Mysterious source of ozone-depleting chemical baffles NASA
A chemical used in dry cleaning and fire extinguishers may have been phased out in recent years but NASA said Wednesday that carbon tetrachloride (CCl4) is still being spewed into the atmosphere from an unknown source.
Mercury's magnetic field tells scientists how its interior is different from Earth's
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.
Huge waves measured for first time in Arctic Ocean
As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water which is predicted to extend across the whole Arctic Ocean before the middle of this century. ...
'Shocking' underground water loss in US drought
A major drought across the western United States has sapped underground water resources, posing a greater threat to the water supply than previously understood, scientists said Thursday.
Voyager spacecraft might not have reached interstellar space
In 2012, the Voyager mission team announced that the Voyager 1 spacecraft had passed into interstellar space, traveling further from Earth than any other manmade object.
Global warming 'pause' since 1998 reflects natural fluctuation, study concludes
Statistical analysis of average global temperatures between 1998 and 2013 shows that the slowdown in global warming during this period is consistent with natural variations in temperature, according to research by McGill ...
Laboratory models suggest that stretching forces shaped Jupiter moon's surface
Processes that shaped the ridges and troughs on the surface of Jupiter's icy moon Ganymede are likely similar to tectonic processes seen on Earth, according to a team of researchers led by Southwest Research Institute (SwRI). ...
Changing Antarctic winds create new sea level threat
New research shows projected changes in the winds circling the Antarctic may accelerate global sea level rise significantly more than previously estimated.
