There is a lost village. After an extremely dry winter, the ruins of Aceredo have emerged. It is not unusual to see rooftops poking above the water in the summer, as the village has been submerged for three decades. After two months without rain, the level of the dam has dropped enough to reveal the entire city.

A whale of a time. A rare image of five whale sharks was captured by a photographer in theMaldives. The golden light of a boat illuminates the sharks as they rise from the depths to feed. The Underwater Photographer of the Year competition was won by the image.

There are mathematical drawings. There is an exhibition at the Science Museum in London that shows the contents of the office of Stephen Hawking. There is a blackboard on display. It was a souvenir of the international conference he organized in Cambridge, UK, in 1980. The participants drew equations, cartoons and jokes on the blackboard. Some of the scribbles refer to the name of the co-organizer, while others depict creatures named after mathematical tools.

There is an oil spill. A marine Biologist near the island of Koh Samet in Thailand is looking at a coral reef for signs of damage after a broken line leaked hundreds of thousands of litres of crude oil into the sea. Efforts to divert the oil from the tourist beaches had been successful, even though authorities feared the spill would wash onto the beach. The clean-up is still going on.

There is a mirror selfies. The telescope took its first selfies in February. The segments of the telescope's primary mirror were captured with a special lens inside the camera. This feature helps to check mirror alignment, it isn't taking selfies just for fun. The bright segment is pointing at a star while the others are not.

There is a black hole. A black hole is hiding in a cloud of dust in the centre of the galaxy. The structures at the centre of some galaxies are known as active galactic nuclei. These bright objects are powered by black holes, which consume a lot of dust and gas. The material spirals towards the black hole. Astronomers were able to build a picture of the cloud and locate the black hole with the help of detailed images and analyses.

A brutal attack. The ancient Egyptian Pharaoh Seqenenre-Taa-II died from a combination of diseases. The ruler's mummified remains show several brutal head injuries that seem to have been inflicted by various weapons. The findings suggest that he was captured and executed during a battle rather than being assassinated in his palace. X-ray investigations in the 1960s revealed wounds on the mummy's head. His death has been a source of speculation ever since.
