The planet’s largest living structure struggling for survival. This coral should be alive with colour but it’s bleached and barren. These scientists are part of a team that’s assessed the health of the entire Great Barrier Reef – an area bigger than Britain – and here the prognosis is poor. On average, two-thirds of the coral in the northern section has died.

We’ve been space-bound since the 1950s, making amazing progress and countless scientific discoveries. But for every advance we’ve left something behind – space junk. At the University of Southampton, scientists are watching this waste. There are now thought to be 22,000 bits of space rubbish bigger than 10 centimetres.
