It’s great to see a burst of galactic activity kick off the year in which we celebrate the 50th anniversary of mankind’s first steps on the moon. On 1st January, NASA’s New Horizons probe passed by the furthest object in our solar system ever to be visited by a spacecraft, sending images of Ultima Thule four billion miles across the galaxy back to Earth. The next day, at 10.26am Beijing time, China’s Chang’E-4 mission made the first-ever landing on the far side of the moon.
