Physicists, chemists and engineers have demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules that may one day serve as drug-delivery vehicles to combat disease and perhaps be used in small batteries that store and release charge.[...]

A stunning new image reveals one of our nearest galactic neighbors, Barnard's Galaxy, also known as NGC 6822. The galaxy contains regions of rich star formation and curious nebulae, such as the bubble clearly visible in the upper left of this remarkable vista. The strange shapes of these cosmic misfits help researchers understand how galaxies interact, evolve and occasionally "cannibalize" each other, leaving behind radiant, star-filled scraps.[...]

Direct communication between Earth and Mars can be strongly disturbed and even blocked by the Sun for weeks at a time, cutting off any future human mission to the Red Planet. An European Space Agency engineer working with engineers in the UK may have found a solution using a new type of orbit combined with continuous-thrust ion propulsion.[...]
