In the recent past, space missions dedicated to the study of astrophysical signals in the high-energy spectrum revealed a series of enigmatic excesses not predicted by the theoretical models. In order to find an explanation for these anomalies, many solutions have been proposed. The most exciting hypothesis invokes the contribution […]

Honeybees are an iconic […]

Heart of darkness: A view of the accretion disc around the supermassive black hole, with jet-like structures flowing away from the disc. The extreme mass of the black hole bends spacetime, allowing the far side of the accretion disc to be seen as an image above and below the black […]

ANIMATION On April 20, 2021, ESA will host the 8th European Conference on Space Debris from Darmstadt, in Germany. Scientists, engineers, industry experts, and policymakers will spend the virtual four-day conference discussing the latest issues surrounding space debris. They will exchange the latest research, try to come up with solutions […]

At the fringes of the Greenland Ice Sheet, where glaciers are constantly melting, water rushes everywhere through an intricate system of lakes and streams that branch out like slip and slide shoots of super chilled, bright turquoise water. Some of that water eventually cascades straight into the surrounding land and […]

Illustration Credit: Cortland Johnson | PNNL Small stockpiles of biomass such as sewage, food waste, and wood chips are often overlooked in visions of future sustainable fuel and chemical production. The dismissal arises because transporting these materials to a large-scale, centralized bio-refinery would require more energy than they produce. Yet […]

Credit: NASA/JPL-Caltech The Ingenuity team has identified a software solution for the command sequence issue identified on Sol 49 (April 9) during a planned high-speed spin-up test of the helicopter’s rotors. Over the weekend, the team considered and tested multiple potential solutions to […]
