Astronomers see misaligned planets in distant system
Using data from NASA's Kepler space telescope, an international team of astronomers has discovered a distant planetary system featuring multiple planets orbiting at a severe tilt to their host star.
Juno spacecraft resumes full flight operations on its way to Jupiter
(Phys.org) —NASA's Juno spacecraft, which is on its way to Jupiter, resumed full flight operations earlier today. The spacecraft had entered safe mode during its flyby of Earth last Wednesday. The safe ...
Diamonds in the sky: Scientists find Jupiter and Saturn are awash in diamonds
Recent work by planetary scientists has indicated that the deep atmospheres of Jupiter and Saturn may contain chunks of diamond floating in a liquid hydrogen/helium fluid.
Juno slingshots past Earth on its way to Jupiter
If you've ever whirled a ball attached to a string around your head and then let it go, you know the great speed that can be achieved through a slingshot maneuver.
Terahertz sensor aiming for Jupiter's moons
A high performance terahertz receiver aiming for space missions such as ESA's "Jupiter icy moons explorer" has been developed in a joint European effort, led by Chalmers University of Technology.
Research duo suggest early Earth had heat-pipe channels similar to Jupiter's moon Io
Long-stressed Europa likely off-kilter at one time
(Phys.org) —By analyzing the distinctive cracks lining the icy face of Europa, NASA scientists found evidence that this moon of Jupiter likely spun around a tilted axis at some point.
Magnetic fields significantly affect hot Jupiter atmospheres, research finds
Determining weather patterns in exoplanet atmospheres – hundreds to thousands of light years away – is extremely difficult. However, given that it may be one of our best ways to truly characterize these ...
Dwarf planet Ceres: 'A game changer in the solar system'
In March of 2015, NASA's Dawn mission will arrive at the dwarf planet Ceres, the first of the smaller class of planets to be discovered and the closest to Earth. Ceres, which orbits the Sun in the asteroid ...
Hubble reveals variation between hot extrasolar planet atmospheres
First results from the analysis of eight 'hot Jupiter' exoplanets suggest that winds and clouds play an important role in the atmospheric make up of these exotic planets. Catherine Huitson of the University ...
Stars don't obliterate their planets (very often)
(Phys.org) —Stars have an alluring pull on planets, especially those in a class called hot Jupiters, which are gas giants that form farther from their stars before migrating inward and heating up.
Stellar winds may electrify exoplanets
(Phys.org) —The strangest class of exoplanets found to date might be even stranger than astronomers have thought. A new model suggests that they are partially heated by electric currents linked to their host stars. Florida ...
Kepler provides insights into unusual dwarf star
(Phys.org) —Astronomer John Gizis of the University of Delaware, working with data obtained by the Kepler mission, is studying a highly unusual dwarf star and its powerful flares that may hold clues to the ...
Big weather on hot Jupiters
Among the hundreds of new planets discovered by NASA's Kepler spacecraft are a class of exotic worlds known as "hot Jupiters." Unlike the giant planets of our own solar system, which remain at a safe distance ...
