We present an interferometer design that provides a null at the star and a direct measurement of both visibility amplitude and phase of the planets.

The ISO-IRAS Faint Galaxy Survey (IIFGS) is a program designed to produce one of the largest and deepest samples of luminous galaxies possible with present facilities.
The Terrestrial Planet Finder (TPF) offers the prospect of revolutionizing humanity's perception of its own place in the Universe by identifying habitable and possibly even life-bearing planets orbiting other stars.
While the baseline for the Next Generation Space Telescope (NGST) is the 1 to 5 um wavelenght interval, compelling astronomical observations become possible at longer wavelenghts.

The conference Working on the Fringe ended with a round-table discussion of the bigger picture of what it takes to ensure science gets done, in this case optical and IR interferometry.
If the dust content of nearby solar system is comparable to, or larger than, that of our own zodiacal disk, the thermal emission from exozodiacal disks will significantly outshine planetary companions to nearby stars.
We present the discovery of a widely separated (258.3+/-0.4) T dwarf companion to the G1 570ABC system.
Before the 2-Micron All-Sky Survey (2MASS) began, only six objects were known with spectral types later than M9.5 V. In the first 371 sq. deg. of actual 2MASS survey data, we have identified another twenty such objects spectroscopically confirmed using the Low Resolution Imaging Spectrograph (LRIS) at the W.M. Keck Observatory.
Zodiacal dust around neighboring stars could obscure the signal of terrestrial planets observed with the Terrestrial Planet Finder (TPF) if that dust is similar to that in the Solar System. Unfortunately, little is known about the presence, or frequency of occurrence of zodiacal dust around stars and so the relevance of zodiacal dust to the design of the TPF, or to the TPF mission, is unknown. It is likely that direct observation of zodiacal dust disks will be necessary to confidently determine the characteristics of individual systems. A survey of a large number of stars in the solar neighborhood that could be candidates for observation with TPF should be undertaken. We present a concept for a space mission to undertake a sensitive, large-scale survey capable of characterizing solar-system-like zodiacal dust around 400 stars within 20 pc of the Sun.
A prototype camera designed to test the observing and data reductions techniques for the 2 Miron All Sky Survey (2MASS) has been used to search for extremely red objects.
We present deep ISOCAM observations taken at 4.5 um (LW1) in search of a faint halo surrounding the edge-on spiral galaxy NGC4565.
