Mapping Alien Continents: Achieving Optical VLBI for Exoplanet Imaging

The scientific goal of the proposed work will be reconstructing the image, ie resolving surface features, of an Earth-like exoplanet around a nearby star as seen in visible light. The innovation is in two stages. First, the design of a new kind of nulling interferometer — “dynamic hierarchical nulling” — combining inputs from multiple apertures and capable of separating star light from planet light with contrast of 10^10 or better in the visible. Second, combine the output beams from two such nullers on spacecraft stationed ~100km apart to achieve the required angular resolution using Michelson interferometric imaging; note that the hierarchical nuller preserves the star’s light in a separate beam which can then be used as in interference phase reference. The capability to survey the features of Earth-like exoplanets is perfectly aligned with NASA priorities and sure to excite public interest.

I vowed from that day on to get his hands on as many tech products as possible. My approach to a review is to make it informative for the technofile while still making it understandable to everyone. Ben is a new voice in the tech industry and is looking to make a mark wherever he goes. When not reviewing products, I is also a 911 Telecommunicator just outside of Pittsburgh PA.
