The Sky at Night team looks back on the major stories of the year and sees how they have developed since they hit the headlines. 2016 has been a remarkable year in many ways, but one area in which it has been particularly good is in space science.

What has the Juno probe discovered at Jupiter? Has Planet 9 been found? And are we any closer to finding Earth-like planets elsewhere in the galaxy?
