Climate change is a looming threat to planet Earth, so scientists have been thinking of solutions. One of them is going to Mars in case Earth becomes inhabitable, as scientists think there might be water on Mars.

Luke used a global network of computers powered by Graphics Processing Units (GPUs), which are widely used in developing artificial intelligence algorithms. Luke’s breakthrough marked the first use of this technology to uncover a prime of this size.
