NASA Engineer’s ‘Helical Engine’ May Violate Laws of Physics
NASA engineer David Burns posted a paper describing the concept of his “helical engine,” which could take humans to the stars by exploiting mass-altering effects known to occur at near-light speed. Unfortunately, it’s been met with skepticism from those who say it violates the conservation of momentum, a core physical law. New Scientist explains: To get to grips with the principle…

Cosmic web fuels stars and supermassive black holes
Astronomers probed the cosmic web, a large-scale structure composed of massive filaments of galaxies separated by giant voids. They found the filaments also contained significant amounts of gas, believed to help fuel the galaxies’ growth. Source: https://earthsky.org/space/cosmic-web-gas-reservoir-fuel-galaxies-growth…
Juno prepares to jump Jupiter’s shadow
NASA’s Juno mission to Jupiter has now successfully executed a 10.5-hour propulsive maneuver. It’ll keep Juno – a solar-powered spacecraft – out of a mission-ending shadow due to have been cast by Jupiter onto the craft in November.
