  Houston TX (SPX) Aug 15, 2019 A colossal, head-on collision between Jupiter and a still-forming planet in the early solar system, about 4.5 billion years ago, could explain surprising readings from NASA's Juno spacecraft, according to a study this week in the journal Nature. Astronomers from Rice University and China's Sun Yat-sen University say their head-on impact scenario can explain Juno's previously puzzling gravitational readings, which suggest that Jupiter's core is less dense and more extended that expected. "Thi ... read more |

 The Lambahraun Lava Field, Islande (AFP) Aug 14, 2019 
To prepare for the next mission to Mars in 2020, NASA has taken to the lava fields of Iceland to get its new robotic space explorer ready for the job.
With its black basalt sand, wind-swept dunes and craggy peaks, the Lambahraun lava field at the foot of Iceland's second biggest glacier, Langjokull, was chosen as a stand-in for the Red Planet's surface.
For three weeks, 15 scientists and ... more |

Scientists have precisely measured the mass and energy of a jet driven by a high-mass protostar, a component and process that scientists estimate is a key to part of stellar formation.
As gas and dust coalesce to form a protostar, the new stellar orb's gravity begins to pull in more and more of the surrounding gas and dust. As the new stellar material condenses, a high-velocity jet form ... more |

 Washington DC (SPX) Aug 12, 2019 
Invisible to the human eye, molecular interactions between gases and liquids underpin much of our lives, including the absorption of oxygen molecules into our lungs, many industrial processes and the conversion of organic compounds within our atmosphere. But difficulties in measuring gas-liquid collisions have so far prevented the fundamental exploration of these processes.

 Seattle WA (SPX) Aug 12, 2019 
Our knowledge of the dwindling sea ice coverage in the Arctic Ocean comes mostly through satellites, which since 1979 have imaged the sea ice from above. The University of Washington's Pan-Arctic Ice Ocean and Modeling System, or PIOMAS, is a leading tool for gauging the thickness of that ice. Until now that system has gone back only as far as 1979.
A new paper now extends the estimate of ... more |
