The first detection of gravitational waves in September 2015 opened a new era of astronomy. For through these vibrations of space-time we can now listen to the events in the cosmos, which do not emit electromagnetic radiation.

In the meantime, scientists from the LIGO collaboration have detected gravitational waves four times, including one with the help of the European Virgo detector. There was recently the Nobel Prize for Physics. All these signals came from merging black holes.

Now comes the next milestone: Astronomers have for the first time detected gravitational waves originating from colliding neutron stars. This was recognizable because, in addition to the vibrations of space-time, electromagnetic radiation was also emitted in almost all wave ranges.
