NASA has captured unprecedented photos of the interaction of shockwaves from two supersonic aircraft, part of its research into developing planes that can fly faster than sound without thunderous “sonic booms”. When an aircraft crosses that threshold – around 1,225 kilometres (760 miles) per hour at sea level – it produces waves from the pressure

In November, Chinese researchers announced that the Experimental Advanced Superconducting Tokamak (EAST) reactor — an “artificial sun” designed to mimic the nuclear fusion process the real Sun uses to generate energy — had hit a milestone by achieving an electron temperature of 100 million degrees Celsius. Now, officials are saying they believe they’ll wrap up

In the course of looking for possible signs of Extra-Terrestrial Intelligence (ETI), scientists have had to do some really outside-of-the-box thinking. Since it is a foregone conclusion that many ETIs would be older and more technologically advanced than humanity, those engaged in the Search for Extra-Terrestrial Intelligence (SETI) have to consider what a more advanced

Some icebergs look white. Others look blue. But perhaps the most precious of all appear emerald green. Ever since the 1900s, sailors and explorers have occasionally seen these strange green icebergs, or jade bergs, floating around in the grey Antarctic landscape.
