Jo van den Brand, spokesperson for the Virgo collaboration, speaks at a press conference on the observation of a signal of the gravitational waves on October 16 in Washington D.C. (XINHUA)
On October 16, scientists from several countries announced separately observation of the "optical counterpart" of gravitational waves coming from the merger of two binary neutron stars. The gravitational waves were first discovered by the U.S.-based Laser Interferometer Gravitational-Wave Observatory two years ago on September 14.
The discovery marks the climax of speculation by Albert Einstein a century ago and the beginning of a new era for astronomy. Following the discovery, more and more secrets to the universe are expected to be uncovered.
