According to NASA, the merger of two neighbouring Galaxies, namely the Milky Way, of which the Solar System is a part and the Andromeda Nebula, is inevitable, since the Galaxies are approaching each other at some 400,000 kilometres per hour.
But the Earth will not get destroyed, nor will humanity suffer in the process, if humans still inhabit the Earth by then. NASA officials said this during a news conference on Thursday.
The merger will begin in approximately four billion years from now and is due over in six billion years.
The new galaxy that will emerge as a result will have a different, most likely elliptical form, and will be populated by fewer cosmic bodies than today.
