  Pasadena CA (JPL) Dec 11, 2018 For the second time in history, a human-made object has reached the space between the stars. NASA's Voyager 2 probe now has exited the heliosphere - the protective bubble of particles and magnetic fields created by the Sun. Comparing data from different instruments aboard the trailblazing spacecraft, mission scientists determined the probe crossed the outer edge of the heliosphere on Nov. 5. This boundary, called the heliopause, is where the tenuous, hot solar wind meets the cold, dense interstell ... read more |

 Prediction of Sun's Activity Over the Next Decade  
Bizarre 'dark fluid' with negative mass could dominate the universeOxford UK (SPX) Dec 06, 2018 It's embarrassing, but astrophysicists are the first to admit it. Our best theoretical model can only explain 5% of the universe. The remaining 95% is famously made up almost entirely of invisible, ... more  |

 Geneva, Switzerland (SPX) Dec 07, 2018 
Although helium is a rare element on Earth, it is ubiquitous in the Universe. It is, after hydrogen, the main component of stars and gaseous giant planets. Despite its abundance, helium was only detected recently in the atmosphere of a gaseous giant by an international team including astronomers from the University of Geneva (UNIGE), Switzerland.
The team, this time led by Genevan research ... more |

NASA's newest Mars lander InSight is slowly readying itself for its scientific mission. The newest images captured by the lander's camera, and shared by NASA, showcase the spacecraft's robotic arm.
The robotic arm can be seen in a flexed position, poised to deploy some of InSight's instruments in the coming days.
One of those instruments is the craft's seismometer. Once deployed, ... more |

 Paris (ESA) Dec 10, 2018 
Every few hours observing the Moon, ESA's 'NELIOTA' project discovers a brilliant flash of light across its surface - the result of an object hurtling through space and striking our unprotected rocky neighbour at vast speed. Based at the Kryoneri telescope of the National Observatory of Athens, this important project is now being extended to January 2021.
Impact flashes are referred to as ... more |

 Paris (ESA) Dec 10, 2018 
The jury is still out as to whether climate change will lead to stronger El Nino events, but while representatives from around 200 countries at the COP24 conference are working to breathe life into the 2105 Paris Agreement, there is a 75-80% chance that a fully-fledged event could be with us in the next couple of months.
El Nino and its cooler cousin, La Nina, are complex naturally occurri ... more |
