The advanced laser interferometric gravitational-wave detectors LIGO
and VIRGO have recently become observatories which are able to detect
transient gravitational-wave signals from the coalescence of
gravitational compact objects. This  has led to triumphal discoveries
awarded with the Nobel prize, which started on September 14, 2015 as
GW150914,  with the first direct detection of gravitational waves from
the coalescence of a binary system of massive black holes by the
Advanced LIGO detectors in two different cites of the States. Then the
several gravitational wave signals were detected  from black holes
mergers.The next  epochal discovery happened on August 17, 2017, with
the first direct observations of gravitational waves from the inspiral
and merger of a binary neutron-star system by the Advanced LIGO and
Virgo collaborations as GW170817, followed 1.7 s later by a weak short
gamma-ray burst detected by the Fermi and INTEGRAL satellites. A
world-wide observing campaign involving about 70 space and ground
based observatories has  led to the detection of multi-wavelength
electromagnetic signals associated with this event. A new
multimessnger era in astronomy and exploration of the most energetic
transients in the sky has started. In the presentation I will give an
overview of the gravitational waves prediction, detectors development,
recent gravitational-wave and multi-mess
