Small, chunky and handy enough to be stuffed in a rucksack for quick facts and tips on the go, six of the book’s eight chapters cover the Solar System, the remainder being devoted to all that lies beyond. An easy-reading book that won’t swamp the reader with complicated terminology and a waffling narrative, writes reviewer Kerry Hebden.


Briny seas maybe lurking on Europa

A decade-long question about the nature of dark spots on Europa’s surface has potentially been solved, with scientists suggesting that these spots are likely signs of irradiated sea salt from a subsurface ocean, deposited onto the surface through interactions with its rocky seafloor. If this is indeed the case, then these findings are an important consideration for assessing the habitability of the planet and whether it could support life or not.
