Engineers at the University of California, Davis have created a device that produces mechanical power at night by taking advantage of the temperature difference between the warmth of the Earth and the extreme cold of outer space. The system could…

This striking image from the science camera on ESA’s Jupiter Icy Moons Explorer (Juice) shows interstellar comet 3I/ATLAS spewing dust and gas. The tiny nucleus of the comet (not visible) is surrounded by a bright halo of gas known as…
