  Irvine, CA (SPX) Feb 07, 2018 An international team of astronomers has determined that Centaurus A, a massive elliptical galaxy 13 million light-years from Earth, is accompanied by a number of dwarf satellite galaxies orbiting the main body in a narrow disk. In a paper published in Science, the researchers note that this is the first time such a galactic arrangement has been observed outside the Local Group, home to the Milky Way. "The significance of this finding is that it calls into question the validity of certain cosmolog ... read more |

 Garching, Germany (SPX) Feb 06, 2018 
A new study has found that the seven planets orbiting the nearby ultra-cool dwarf star TRAPPIST-1 are all made mostly of rock, and some could potentially hold more water than Earth. The planets' densities, now known much more precisely than before, suggest that some of them could have up to 5 percent of their mass in the form of water - about 250 times more than Earth's oceans.
The hotter ... more |

 Mountain View, CA (SPX) Feb 06, 2018 
New research published in Nature Astronomy seeks to understand how surface clay was formed on Mars despite its cold climate.
The climate on early Mars has presented an enigma for planetary scientists because surface features such as valley networks indicate abundant liquid water was present and the clay minerals found in most ancient surface rocks need even warmer temperatures to form, whi ... more |

 Lawrence KS (SPX) Feb 02, 2018 
On a ho-hum day some 12,800 years ago, the Earth had emerged from another ice age. Things were warming up, and the glaciers had retreated.
Out of nowhere, the sky was lit with fireballs. This was followed by shock waves.
Fires rushed across the landscape, and dust clogged the sky, cutting off the sunlight. As the climate rapidly cooled, plants died, food sources were snuffed out, and ... more |

The world's vast oceans and seas offer seemingly endless spaces in which adversaries of the United States can maneuver undetected. The U.S. military deploys networks of manned and unmanned platforms and sensors to monitor adversary activity, but the scale of the task is daunting and hardware alone cannot meet every need in the dynamic marine environment. Sea life, however, offers a potential new ... more |

Acoustic tractor beams use the power of sound to hold particles in mid-air, and unlike magnetic levitation, they can grab most solids or liquids. For the first time University of Bristol engineers have shown it is possible to stably trap objects larger than the wavelength of sound in an acoustic tractor beam. This discovery opens the door to the manipulation of drug capsules or micro-surgical im ... more |
