Upon launch, the occulter is folded and then starts to unfurl into a sunflower-like structure in front of a space telescope. It is an occulter, or a device that blocks excessive light to allow observation of fainter bodies. To work around this difficulty, engineers at NASA's Jet Propulsion Lab have developed the Starshade. The problem: some stars emit so much light that detecting exoplanets is difficult. One of the persisting efforts in astronomy is finding exoplanets with the goal of studying them and ultimately finding another that can support life as with Earth. The polyhedral enclosure opens and closes when a motor applies torque to the base where the "petals" meet, these petals then fold to actuate the enclosure. Paulson School of Engineering and Applied Science (SEAS), and Radcliffe Institute for Advanced studies have collaborated to create an origami-inspired folding structure that can safely handle marine life. Researchers from Harvard University's Wyss Institute, John A. Among the wonders kept hidden are the life in the deep waters - from elusive jellyfishes and octopi to other organisms that are unbelievably old. Marine Biology: Robot Grabber for Sea CreaturesĪccording to the National Oceanic and Atmospheric Administration (NOAA), more than eighty percent of the oceans remain unmapped, unobserved, and unexplored. The giant sunflower-like structure would be used to acquire images of Earth-like rocky planets around nearby stars.
