All the planets Kepler has picked up made themselves known by blocking their star's light as they crossed, or transited, in front of the star.

But the way TESS will search for exoplanets is the same as Kepler: The satellite will watch stars for signs of dimming, which can indicate that a planet is transiting, or crossing in front of, the star.

Joshua Winn, an associate professor of physics at the Massachusetts Institute of Technology and former member of the Kepler team, said that efficient methods to confirm planets will become more crucial as NASA plans and launches more space telescopes, such as the Transiting Exoplanet Survey Satellite (TESS), which is expected to find tens of thousands of exoplanets.

Kepler, which will keep a continuous watch on a patch of stars for more than three years, is better suited to finding planets like our own in terms of orbital periods as well as other parameters, although it will likely be a few years before it moves from the hot objects it has already discovered to cooler, potentially habitable worlds, whose transits are subtler and less frequent.

These transits can be thought of as tiny eclipses of the host star by a planet (or planets) as seen from Earth.

Kepler continuously tracks more than 150,000 stars; when a planet passes in front of one of them, in a kind of mini eclipse known as a transit, the spacecraft registers a slight dip in the star's apparent brightness.

The findings have direct implications for future NASA missions, such as the Transiting Exoplanet Survey Satellite and James Webb Space Telescope, which will try to detect possible habitable planets and characterize their atmospheres.

They were able to measure the slight decrease in brightness as the planet and its atmosphere absorbed some of the starlight while transiting (passing in front of) the host star.

The lower abundance of diluted binaries between 0.1 and 0.4 % transit depth, which possibly continues towards lower - amplitude candidates, may facilitate the transit - searches for small extrasolar planets in both CoRoT data and in upcoming or planned search projects, such as Kepler or PLATO, reducing the load of required follow - up observations.

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.

Finally, the planet - distribution of Brown (2003) is one of hot giant planets; CoRoT's results contain to date 5 hot giants which follow approximately the distribution of Brown, and one terrestrial planet (CoRoT - 7b), visible as a small peak at a transit depth of 0.04 % in Fig. 2.
