NASA engineers are studying the feasibility of a giant starshade that could be remotely positioned to block out a targeted sun, allowing a precisely positioned space telescope tens of thousands of kilometers away to directly image Earth-size exoplanets that otherwise would be drowned out in the star’s glare.

 

In the system currently being modeled, the starshade would unfold in space like a flower blossom, expanding to a diameter of 26 meters (85 feet) or so. The exoplanet-hunting telescope would then be positioned up to 40,000 kilometers (25,000 miles) away. For that system to work, the two spacecraft would have to maintain their precise separation to within 1 meter (3 feet).

In another indication of the frightening pace at which nano and biotechnology is now moving, scientists have developed a technique that gives mice a near infra-red spectrum of vision, allowing them to see in the dark. Night goggles use infrared light and researchers have found a similar effect can be achieved by injecting specially designed ‘nanoparticles’ directly into the eyes of mice. And humans could follow.

 

After injection, the nanoparticles that gave the mice ‘super sight’ sit at the back of their retinas. From that position, they convert near infrared light that is normally invisible to the eye into a form of visible light. Effectively meaning the mice could see in the dark in a way similar to how they would if fitted with a set of high-tech night goggles like those used in the military. Over several weeks, the body gradually removes the nanoparticles without any visible ill effects on the mice.
