They've done it. It has taken them all year but Izzie Clarke and Dr Becky Smethurst have reached the final planet in our solar system; Neptune.
Dr Leigh Fletcher from the University of Leicester is back to cover the basics of the planet and Carolyn Kennett, Chair of the Society for the History of Astronomy, tells Izzie about its controversial discovery. Plus, Dr Robert Massey is on hand for some winter stargazing.
