A NASA mission dedicated to discovery of planets around others stars through observation of planets transits.

Kepler Mission: A Search for Terrestrial Planets It is a special purpose space mission in the NASA Headquarters Discovery Program for detecting terrestrial planets, that is, rocky and Earth-size, around other stars. How can extra solar terrestrial planets be detected? When a planet passes in front of its parent star, as seen by us, it blocks a small fraction of the light from that star. If the dimming is truly caused by a planet, then the transits must be repeatable. Measuring three transits all with a consistent period, duration and change in brightness provides a rigorous method for discovering and confirming planets planets even smaller than the...

Describes several projects aiming to detect extra-solar planets.

UStAPS University of St.Andrews Planet Search Doppler surveys show that 1% of nearby main sequence stars host Hot Jupiters in 3-4 day 0.05 AU orbits. 10% of these will have orbits close enough to edge-on for the planet to transit in front of the star. Thus 1 in 1000 main sequence stars should wink every 3-4 days. Jupiter transiting the Sun produces a 1% wink easy to detect by differential CCD photometry. Lower mass main sequence stars are smaller, making their winks even deeper. There are many transit searches underway worldwide. St.Andrews is pursuing both Deep and Wide transit searches.

Extra-Solar Planet Search A series of preliminary tests were conducted to discover how to get the greatest sensitivity in our measurements. Now that those tests have been completed, we are expanding our efforts to begin a full scale survey project. This includes our joining the collaboration to operate the 1.3-m telescope on Kitt Peak. Overview Since the discovery of the first planet around 51 Pegasi, there has been an increased interest in the search for Extra-Solar planets. The links below will give you a brief overview of other, commonly used search methods, details of our method of choice (the transit method as well...

Extrasolar Planet Detection with the AFOE The Advanced Fiber-Optic Echelle (AFOE) spectrometer is a fiber-fed, bench-mounted echelle spectrograph, located at the 1.5m telescope of the Whipple Observatory, near Tucson, Arizona.

Extrasolar Planet Detection with the AFOE Extrasolar planet detection is the search for planets around other stars than our Sun. Several techniques are being used to detect planets around other suns; they are discussed in a Scientific American Exploration Web page. The AFOE has been designed to provide the required precison and stability to detect the wobble induced on the star by the presence of a planet. Indeed, both the planet and the star revolve around their common center of gravity. While the center of gravity is very close to the center of the star, it is not exactly at the center of the star. Therefore...

UMBRAS (Umbral Missions Blocking Radiating Astronomical Sources) is a technique and a class of space science missions. The UMBRAS goal is direct observation of planets around other stars Direct observation means images, photometry, and spectroscopy, as contrasted to the measurement of stellar reflex motion and variations in starlight flux used to demonstrate the discovery of extrasolar planets found so far. UMBRAS uses a companion spacecraft with a space telescope placed far from Earth. The companion spacecraft carries an occulting screen designed to reduce the glare...

Worldwide Network of Astronomers Searching for Extra-Solar Planets

The purpose of is to coordinate and direct a cooperative observational effort which will allow experienced amateur astronomers and small college observatories to discover transiting extrasolar planets.
site exerpt Jupiter type planets such as HD 209458 b, OGLE TR56-b, and TrES-1 have added an additional element of excitement to the quest for alien solar systems. Furthermore, the past several years have seen the introduction of highly affordable small telescopes equipped with sensitive CCD detectors. A large number of amateur astronomers and small colleges own observatories which, when properly configured, are capable of reliably detecting the periodic dimming that occurs when a close-in giant planet passes in front of its parent star as seen from Earth. This technique has been used by amateurs worldwide to detect the planetary transits of...
