The Kepler Space Telescope was specifically designed to detect exoplanets using the transit method.

The Kepler Space Telescope uses the transit method to detect exoplanets, which involves observing the dimming of a star's light as an exoplanet passes in front of it.

The radial velocity method detects exoplanets by measuring the Doppler shift in the light of the host star caused by the gravitational pull of the exoplanet.

A spectrograph is used to measure the radial velocity of a star by splitting the light into its component wavelengths and detecting the Doppler shift.

The microlensing method detects exoplanets by observing the gravitational lensing of light from a background star caused by the presence of an exoplanet.

A telescope is used to measure the microlensing of light by observing the change in brightness of a background star caused by the gravitational lensing of its light by an exoplanet.

The astrometry method detects exoplanets by measuring the parallax of the host star caused by the gravitational pull of the exoplanet.

A telescope is used to measure the astrometry of a star by observing the change in position of the star caused by the gravitational pull of an exoplanet.

Astrometry can be used to measure the mass of an exoplanet by observing the wobble of the host star caused by the gravitational pull of the exoplanet.

Photometry can be used to measure the radius of an exoplanet by observing the transit of the exoplanet across the host star.

Spectrography can be used to measure the composition of an exoplanet's atmosphere by analyzing the light that passes through the atmosphere.

Photometry can be used to measure the temperature of an exoplanet by observing the amount of infrared radiation emitted by the exoplanet.

Spectrography can be used to measure the surface pressure of an exoplanet by analyzing the absorption lines in the exoplanet's atmosphere.

Spectrography can be used to measure the magnetic field of an exoplanet by analyzing the Zeeman effect in the exoplanet's atmosphere.

Photometry can be used to measure the rotation period of an exoplanet by observing the variation in the exoplanet's brightness as it rotates.
