The invisible auroras on Mars come to life in a new NASA animation

The sky on Mars has a wind of ultraviolet light that pulsates as it moves across the red planet. This phenomenon is similar to events on Earth with the aurora borealis, which lasted from sunset to midnight, and NASA has created a new animation using data from a MAVEN spacecraft instrument to demonstrate what future astronauts might look like in …

We underestimated the pace at which the Arctic is melting

Credit: CC0 Public Domain Ice sea ice is melting faster than expected. Today’s climate models have not yet included the sharp rise in temperatures over the past 40 years. This shows a new study by researchers from the University of Copenhagen and other institutions. Temperatures in the Arctic Ocean between Canada, Russia and Europe are warming faster than researchers’ climate …

Deep learning and metamaterials make the invisible visible

Credit: Bakhtiyar Orazbayev / EPFL By combining specially designed materials and neural networks, EPFL researchers have shown that sound can be used in high-resolution images. Image imaging allows us to depict an object through remote field analysis of the light and sound waves it transmits or emits. The shorter the wave, the higher the image resolution. However, the level of …
