  Pasadena CA (JPL) Nov 05, 2019 One year ago, on Nov. 5, 2018, NASA's Voyager 2 became only the second spacecraft in history to leave the heliosphere - the protective bubble of particles and magnetic fields created by our Sun. At a distance of about 11 billion miles (18 billion kilometers) from Earth - well beyond the orbit of Pluto - Voyager 2 had entered interstellar space, or the region between stars. This week, five new research papers in the journal Nature Astronomy describe what scientists observed during and since Voyager 2's h ... read more |

Simulations explain giant exoplanets with eccentric, close-in orbitsSanta Cruz CA (SPX) Oct 31, 2019 As planetary systems evolve, gravitational interactions between planets can fling some of them into eccentric elliptical orbits around the host star, or even out of the system altogether. Smaller pl ... more

Even 'goldilocks' exoplanets need a well-behaved starHouston TX (SPX) Nov 01, 2019 An exoplanet may seem like the perfect spot to set up housekeeping, but before you go there, take a closer look at its star. Rice University astrophysicists are doing just that, building a computer ... more  
Scientists may have discovered whole new class of black holesColumbus OH (SPX) Nov 01, 2019 Black holes are an important part of how astrophysicists make sense of the universe - so important that scientists have been trying to build a census of all the black holes in the Milky Way galaxy. ... more

In a decade's time, an exciting new visitor will enter the Jovian system: ESA's Jupiter Icy Moons Explorer, or Juice. As its name suggests, the mission will explore Jupiter and three of its largest moons - Ganymede, Callisto and Europa - to investigate the giant planet's cosmic family and gas giant planets in general.
Juice is planned for launch in 2022, and its instruments are currently b ... more |

 Tokyo, Japan (SPX) Nov 03, 2019 
A research team at The University of Tokyo has reproducibly synthesized staircase-like supramolecules of a single handedness, or chirality, using standard laboratory equipment.
By gradually removing the solvent from a rotating solution containing non-chiral precursors, they were able to produce helixes that twist preferentially in a particular direction. This research may lead to new and c ... more |

A study has concluded that the earliest ancestors of anatomically modern humans (Homo sapiens sapiens) emerged in a southern African 'homeland' and thrived there for 70 thousand years.
The findings were published this week in the journal Nature. The authors propose that changes in Africa's climate triggered the first human explorations, which initiated the development of humans' genetic, e ... more |

As ESA's SMOS satellite celebrates 10 years in orbit, yet another result has been added to its list of successes. This remarkable satellite mission has shown that it can be used to measure how the temperature of the Antarctic ice sheet changes with depth - and it's much warmer deep down.
The Antarctic ice sheet is, on average, about 2 km thick, but in some places the bedrock is almost 5 km ... more |

 Boston MA (SPX) Oct 16, 2019 
Astronomers at MIT and elsewhere have used a massive cluster of galaxies as an X-ray magnifying glass to peer back in time, to nearly 9.4 billion years ago. In the process, they spotted a tiny dwarf galaxy in its very first, high-energy stages of star formation.
While galaxy clusters have been used to magnify objects at optical wavelengths, this is the first time scientists have leveraged ... more |
