Both Kepler and TESS are designed to scan the sky
for planetary transits, the slight dimming that occurs when a planet moves across the face of a star and temporarily blocks some of its glow.
Like Kepler and the European CoRoT satellite before it, TESS will search
for planetary transits: brief dimmings of starlight, occurring at regular intervals, that betray the shadowing presence of an unseen exoplanet.
The James Webb Space Telescope will look
for planetary transits and measure and record light intensity at various wavelengths, telling us much about the planet's atmosphere.

The
transit zone is rich in host stars
for planetary systems, offering approximately 100,000 potential targets, each potentially orbited by habitable planets and moons, the scientists say — and that's just the number we can see with today's radio telescope technologies.
One method that has been discussed
for years but has yet to bear fruit is known as
transit timing — if a planet passes in front of its host star so that it blocks out a small but detectable fraction of the star's light, researchers can time the arrival of that partial eclipse, known as a
planetary transit.

planetary radius and multiplicity.
For most of the candidates (85 %), the transit depths measured with Kepler are consistent with the depths measured with Spitzer as expected for planetary objects, while we find that the most discrepant measurements are due to the presence of unresolved stars that dilute the photomet

For Kepler - 20c and Kepler - 20d, the blend scenario is independently disfavored by the achromaticity of the
transit: From Spitzer data gathered at 4.5 um, we infer a ratio of the
planetary to stellar radii of 0.075 + -0.015 (Kepler - 20c) and 0.065 + -0.011 (Kepler - 20d), consistent with each of the depths measured in the Kepler optical bandpass.
