Pale Blue Dot: Detecting Other Habitable Worlds This 1996 workshop sponsored by NASA Ames Research Center explored the key questions and challenges associated with detecting life on an extrasolar planet. The workshop included sessions on three related topics: the biogeochemistry of biogenic gases in the atmosphere, the chemistry and spectroscopy of planetary atmospheres, and the remote sensing of planetary atmospheres and surfaces.
Pale Blue Dot II
Workshop (1999) This May 1999 workshop at NASA Ames Research Center addressed the detection and study of habitable and inhabited worlds beyond our own solar system.
A roadmap for the Exploration of Neighboring Planetary Systems (ExNPS) The ExNPS Road Mapconsists of a variety of ground-based and space-based initiatives that will culminate in the flight of an infrared interferometer with enough sensitivity to make "family portraits" of planets orbiting nearby stars and to detect CO2, O3 and H2O in the atmosphere of an Earth-like planet up to 13 parsecs away. [NASA Jet Propulsion Laboratory]
The Kepler Mission Kepler is a proposed extrasolar planet detection mission that woudl measure the trasnit of extrasolar planets in front of their parent star. From the brightness change the planet size can be calculated. From the period the orbital size can be calculated and the planet's temperature estimated. NASA Ames Research Center.
Infra-Red Space Interferometer DARWIN DARWIN (IRSI) is a cornerstone candidate in the ESA Horizon 2000+ science plan. The goals for this mission is for the first time to detect terrestial planets in orbit around other stars than our Sun and to allow, also for the first time, high spatial resolution imaging in the approximately 6-30 micrometer wavelength region. European Space Agency.
Darwin: The search for other worlds Darwin is a proposed extrasolar planet detection program that will use five or six 1m class telescopes, which together will form a nulling (Bracewell) interferometer. Darwin will operate at the L2 Lagrangian point in the Sun-Earth system European Space Agency.
Darwin A proposal to ESA for a space-based interferometer dedicated to finding Earth-like planets. Hosted at Space Infrared Interferometry Working Group, Rutherford Appleton Laboratory (RAL)
PLANET - Probing Lensing Anomalies NETwork This website described a proposed method of extrasolar planetary detection that uses gravitational microlensing caused by large distant objects as an optical telescope of sorts that could allow planets down to the size of Earth to be detected at great distances. Kapteyn Institute Department of Astronomy.
Vulcan Camera Project The Vulcan Camera Project is sponsored by NASA Ames Research Center designed to detect large planets around other stars. Vulcan uses differential photometry to measure the amount of light coming from target stars in the Vulcan camera's wide field of view. Periodic fluctuations in received light could indicate the presence of a large planet in orbit about the target star.
The Wyoming-Arizona Search for Planets (WASP) WASP uses the photometric method (or the occultation/transit method). The brightnesses of a large sample of stars are monitored with very high precision. If a planet or other large companion transits across the disc of the star as seen from Earth, there will be a small decrease in the light seen from that star.
Brown Dwarf and Extrasolar Giant Planet Thermal Fluxes This page presents a collection of model emitted fluxes for extrasolar giant planets (EGPs) and brown dwarfs.
Exoplanets: Discoveries of Worlds Orbiting Other Stars This University of Arizona website contains references to astronomical programs, both ground- and space-based, that are in search of extrasolar planets. Links to data, theory, and speculations about the exoplanets themselves are also presented including an extensive table of known extrasolar planets is maintained.
The Anglo-Australian Planet Search Program This project monitors the 200 nearest and brightest Sun-like stars visible from the Southern Hemisphere with the high resolution echelle spectrometer (UCLES). UCLES covers the entire visible wavelength region. Doppler shifts in the stellar spectra are measured with reference to a precision calibrated iodine vapour (absorption) cell. Anglo-Australian Observatory.
COROT A space mission dedicated to the seismology of celestial bodies and to the study of extrasolar planets COROT is a space mission approved by the French Space Agency CNES, with a participation of the ESA Solar System Departement at ESTEC and the University of Vienna.
Extrasolar Planet Detection with the AFOE The Advanced Fiber-Optic Echelle (AFOE) spectrometer is a fiber-fed, bench-mounted echelle spectrograph. The AFOE has been designed to provide the required precison and stability to detect the wobble induced on a star by the presence of a planet.
STARE (STellar Astrophysics & Research on Exoplanets) STARE uses precise time-series photometry to search for extrasolar giant planets transiting their parent stars. An important byproduct of STARE will be an unusually complete survey of variable stars within its selected fields-of-view. High Altitude Observatory.
GAIA - Global Astrometric Interferometer for Astrophysics GAIA is an advanced astrometric mission proposed as a Cornerstone Mission within the ESA Horizon 2000+ science plan, that aims to measure distances and velocities of more than a billion stars in our Galaxy and to provide highly accurate astrometric data.
