WHAT IS BLUE LAVA?

Most people - if they've heard of it at all - are aware of 'blue lava' thanks to the otherworldly photographs of French photographer Olivier Grunewald.

WHAT SHOULD I DO IF I GET STRANDED ON SNAKE ISLAND?

Just off the coast of southern Brazil lies the island of Queimada Grande, known as 'Snake Island'. Covering just 43 hectares (106 acres), this rocky island is home to between 2,000 and 4,000 highly venomous golden lancehead vipers (Bothrops insularis), which can grow to 70cm (just over 2ft). The snakes were trapped there around 11,000 years ago, at the end of the last ice age, when rising sea levels cut them off from the mainland.

Earth is blanketed by a swarm of human-made debris hurtling around at speeds of up to 8km per second - about five times the speed of a bullet. The UK's Earth & Space Sustainability Initiative hopes to catch these fast-moving projectiles and clean up the nasty, and potentially lethal, mess our cosmic littering habit has caused
