We human beings,living on the earth,which is only a small planet in Galaxy, can never give up the exploration of space. Curiosity to the outside world compels us to take one more step by step. Fortunately, everything ever existed or every events ever happened in the universe can convey messages to us simultaneously.
Before reading this article,I think seeing through our eyes maybe the only way that can we explore the cosmos.However,that's too naive.We can even hear the gravitational waves and taste the neutrios after the merger of two neutron stars.What an absolutely amazing discovery! Furthermore, the scientists confirm a theory that colliding neutron stars are a primary cosmic source of gold and other precious metals.Besides, the messages also make the probe to the nature of dark energy, the mysterious force easier.
All above achievements cannot come out of nowhere. Those astronomic researchers dropped everything including families and kids except telescopes. Thanks a lot for their payments to astronomy bring to us more knowledges of the space beyond our sight line.
