The ability of space-based telescopes to image the distant Universe could be in peril, according to new research investigating the impacts of light-pollution from future satellites. Streaks of reflected light from satellites currently in low-Earth orbit are already seen in telescope images, and planned launches could raise the number of satellites from around 15,000 to more than half-a-million. Computer modelling revealed that this drastic increase would result in images taken by instruments such as the Hubble Space Telescope becoming unusable by astronomers. The team proposes a series of strategies to help mitigate these impacts, preventing this future becoming reality. Glitches in video calls are an annoying feature of everyday life, but these brief interruptions could have serious real-world impacts, according to analysis from a team of researchers. In one experiment, the team found that video calls with glitches decreased the likelihood of someone being hired for a job. Analysis... learn more
