Astronomers have spotted a pair of enormous jets emanating from a supermassive black hole with a combined length of 23 million light years — the biggest ever discovered. Jets are formed when matter is ionized and flung out of a black hole, creating enormous and powerful structures in space. Thought to be unstable, physicists had theorized there was a limit to how large these jets could be, but the new discovery far exceeds this, suggesting there may be more of these monstrous jets yet to be discovered.

Making metal alloys is typically a multi-step process that creates huge amounts of emissions. Now, a team demonstrates a way to create these materials in a single step, which they hope could significantly reduce the environmental burdens associated with their production. In a lab demonstration, they use their technique to create an alloy of nickel and iron called invar — a widely-used material that has a high carbon-footprint. The team show evidence that their method can produce invar to a quality that rivals that of conventional manufacturing, and suggest their technique is scalable to create alloys at an industrial scale.
