The previous best broadband null at 10 microns was 50,000:1 at 32% bandwidth, also by the Adaptive Nuller and reported in February this year.

07.02.13 The Adaptive Nuller Testbed at JPL has demonstrated a 50,000:1 rejection ratio with a bandwidth of 32% (full width at half maximum) in the band from 8-12 microns. The Adaptive Nuller uses a deformable mirror (DM) at the focus of a spectrometer to adjust phase by pistoning the individual elements along the spectrum, and intensity by tilting those same elements (thus adjusting shear at an output pupil stop). The previous best broadband null at 10 microns was about 20,000:1 at 18% bandwidth using the laboratory version of the Keck Nuller. The revised requirements for nulling with either TPF-I or Darwin suggest that a 100,000:1 rejection ratio is sufficient for detecting Earth-like planets. Thus the current laboratory work is only about a factor of 2 away from flight requirements.
07.02.09 The membership of the ExoPlanet Task Force has been announced. The NSF-NASA-DOE Astronomy and Astrophysics Advisory Committee (AAAC) established an ExoPlanet Task Force (ExoPTF) as a subcommittee to advise NSF and NASA on the future of the ground-based and space-based search for and study of exo-planets, planetary systems, Earth-like planets and habitable environments around other stars. Steve Ridgway is the point of contact at NASA Headquarters.
07.02.09 Ming Zhao, a student of John Monnier at the University of Michigan, was awarded a Michelson Graduate Fellowship this year. His work will focus on direct detection of extrasolar planets using the CHARA Interferometer, as well as high-resolution imaging studies of rapidly-rotating hot star photospheres and Be star disks.

07.01.05 The Applied Physics Group at Tel Aviv University have produced high-quality single mode silver halide fiber optics. Silver halide fibers transmit in the wavelength range above 10 microns and complement the already available single-mode chalcogenide fibers produced by other groups, such as the Naval Research Laboratory. These fibers are used in the nulling interferometry testbeds of the Terrestrial Planet Finder Interferometer at the Jet Propulsion Laboratory.
