Some details of Saturn rings (Image NASA/JPL-Caltech/Space Science Institute)

During the American Astronomical Society Division for Planetary Science meeting some of the latest discoveries were presented about the planet Saturn and its rings obtained from data collected by the Cassini space probe before disintegrating in the planet’s atmosphere on September 15. Some of the results were published in “The Astrophysical Journal”.

Yesterday ESO and LIGO/VIRGO collaboration held a press conference to present the results of a complex research that led to the discovery of the merger of two neutron stars observed in the emission of both electromagnetic and gravitational waves. These findings were collected in a series of articles that were published or will be published in the magazines “Nature”, “Nature Astronomy”, “Astrophysical Journal Letters” and “Physical Review Letters”.

An article published in the journal “Nature” describes the discovery of a ring around the dwarf planet Haumea. A team led by astronomers at the Astrophysical Institute of Andalucía (Instituto de Astrofísica de Andalucía, IAA-CSIC) in Spain used observations of several telescopes to find the ring, the first located around a trans-neptunian object, and to get better estimates of other Haumea characteristics.
