  Pasadena CA (JPL) Jun 11, 2018 Ever since NASA's Voyager 1 spacecraft flew past Jupiter in March, 1979, scientists have wondered about the origin of Jupiter's lightning. That encounter confirmed the existence of Jovian lightning, which had been theorized for centuries. But when the venerable explorer hurtled by, the data showed that the lightning-associated radio signals didn't match the details of the radio signals produced by lightning here at Earth. In a new paper published in Nature, scientists from NASA's Juno mission desc ... read more |

Hubble spots most distant star ever observedLa Laguna, Spain (SPX) Jun 08, 2018 If we could travel halfway across the Universe, we would find a huge star,christened Icarus, that was found after its discovery to be the most distant star from Earth. Normally, it would be impossib ... more 
More Mystery Objects Found Near Milky Way's Black HoleKamuela HI (SPX) Jun 08, 2018 Astronomers have discovered several bizarre objects at the galactic Center that are concealing their true identity behind a smoke screen of dust; they look like gas clouds, but behave like stars. ... more 
The disc of the Milky Way is bigger than we thoughtLa Laguna, Spain (SPX) Jun 08, 2018 Spiral galaxies such as the Milky Way have discs which are really thin, in which the major fraction of their stars are found. These discs are limited in size, so that beyond certain radius there are ... more  
How solar prominences vibrateLa Laguna, Spain (SPX) Jun 08, 2018 When we look at the surface of the Sun the solar prominences are seen as dark filaments that populate the disk or as a blaze of plasma above it. Solar prominences are very dense plasma structures th ... more 
Researchers discover multiple alkali metals in unique exoplanetLa Laguna, Spain (SPX) Jun 08, 2018 The extrasolar planet WASP-127b is one of the least dense exoplanets ever found.

NASA has approved an update to Juno's science operations until July 2021. This provides for an additional 41 months in orbit around Jupiter and will enable Juno to achieve its primary science objectives.Juno is in 53-day orbits rather than 14-day orbits as initially planned because of a concern about valves on the spacecraft's fuel system. This longer orbit means that it will take more time to c ... more |

Opportunity is halfway down in "Perseverance Valley" on the west rim of Endeavour Crater.
The science team is pursuing several hypotheses as to the origin of the valley. The rover is still positioned near some tabular rocks that are the subject of an in-situ (contact) investigation. Over several days (sols), the Panoramic Camera (Pancam) has been employed to collect extensive imagery of va ... more |

For anyone who has ever wished there were more hours in the day, geoscientists have some good news: Days on Earth are getting longer.
A new study that reconstructs the deep history of our planet's relationship to the moon shows that 1.4 billion years ago, a day on Earth lasted just over 18 hours. This is at least in part because the moon was closer and changed the way the Earth spun around ... more |

Caltech scientists have found, for the first time, that merging pairs of neutron stars - the burnt-out cores of stars that have exploded - create the majority of heavy elements in small "dwarf" galaxies. Heavy elements, such as silver and gold, are key for planet formation and even life itself. By studying these dwarf galaxies, the researchers hope to learn more about the primary sources of heav ... more |

To mark World Ocean Day, Global Fishing Watch (GFW) has increased ocean transparency by releasing the first-ever 'live' global view of likely transshipping at sea - a practice that can mask illegal fishing activity, and imagery of night-time fishing and its location, exposing vessels often hidden from other monitoring systems.
Data released on GFW's map reveals in near real-time the locati ... more |

Once every month, on average, somewhere on Earth a fireball appears out of nowhere and for mere seconds, casts a blinding flash across the sky before it blows up in a thunderous explosion. It happened last Saturday over southern Africa, where a small space rock disintegrated in the night sky and - possibly - scattered debris on the ground, awaiting discovery by meteorite hunters.

When we look at the surface of the Sun the solar prominences are seen as dark filaments that populate the disk or as a blaze of plasma above it. Solar prominences are very dense plasma structures that levitate in the solar atmosphere.
It is generally believed that the star's magnetic field supports them so that they do not fall on the surface due to their own weight. These magnetic structu ... more |
