Many people have heard of a movie called Interstellar. The interstellar space begins where the Sun’s magnetic field ends.
This region is beyond the solar system. To be more precise, the interstellar region begins where the true boundaries of our solar system end. A group of scientists have devised a plan to send creatures to this infinite and unknown region.
Scientists at the University of California, Berkeley in the US are behind this. Their research is funded by NASA. The research project is called the Starlight Project.
