This artist's impression shows two tiny but very dense neutron stars at the point at which they merge and explode as a kilonova. Such a very rare event is expected to produce both gravitational waves and a short gamma-ray burst, both of which were observed on 17 August 2017 by LIGO--Virgo and Fermi/INTEGRAL respectively. Subsequent detailed observations with many ESO telescopes confirmed that this object, seen in the galaxy NGC 4993 about 130 million light-years from the Earth, is indeed a kilonova. Such objects are the main source of very heavy chemical elements, such as gold and platinum, in the Universe.

Colisión de estrellas dispersa oro y platino

Por primera vez, científicos pudieron observar el choque de dos estrellas de neutrones. La colisión causó ondas gravitacionales, una ráfaga de luz y la dispersión de metales preciosos por el universo.
