  Geneva, Switzerland (SPX) Sep 17, 2019 A team of researchers has reignited the debate about the age of Saturn's rings with a study that dates the rings as most likely to have formed early in the solar system. In an article published in Nature Astronomy and presented at the EPSC-DPS Joint Meeting 2019 in Geneva, the authors suggest that processes that preferentially eject dusty and organic material out of Saturn's rings could make the rings look much younger than they actually are. Cassini's dive through the rings during the missi ... read more |

 Geneva, Switzerland (SPX) Sep 17, 2019 
Analysis of a bright flash in Jupiter's atmosphere observed by an amateur astronomer in August 2019 has revealed that the likely cause was a small asteroid with a density typical of stony-iron meteorites. The impact is estimated to have released energy equivalent to an explosion of 240 kilotons of TNT - around half the energy released in the 2013 Chelyabinsk event at Earth. The results have been ... more |

The Large Magellanic Cloud, or LMC, is one of our nearest galactic neighbors, at only 163 000 light years from Earth. With its sibling the Small Magellanic Cloud, these are among the nearest dwarf satellite galaxies to the Milky Way. The LMC is also the home of various stellar conglomerates and is an ideal laboratory for astronomers to study the processes that shape galaxies.

Experimenting at 2.2 million degrees Celsius, physicists at Sandia National Laboratories' Z machine have found that an astronomical model - used for 40 years to predict the sun's behavior as well as the life and death of stars - underestimates the energy blockage caused by free-floating iron atoms, a major player in those processes.
The blockage effect, called opacity, is an element's natu ... more |

 Washington (UPI) Aug 30, 2019 
Stone tools recovered from an archaeological dig in western Idaho suggest humans were living in the region at least 16,000 years ago, 1,000 years earlier than previously thought.
The discovery, published Friday in the journal Science, supports the theory that the earliest human migrations into the Americas followed a Pacific coastal route, not an inland ice-free corridor.
