Question

A. The transit method
B. James Webb telescope
C. Direct imaging
D. Radial velocity
E. Spectroscopes
F. Measuring the movement of moons and planets

Answer 1

The three methods used to detect exoplanets in dark space are:

1. The transit method: This involves monitoring the light from a star and looking for regular, slight dips in brightness that occur when an exoplanet passes in front of it.

2. Radial velocity: By observing the slight wobble in a star's motion caused by the gravitational tug of an exoplanet, this method can detect the presence of unseen planets.

3. Direct imaging: Advanced telescopes like the James Webb Space Telescope can directly capture images of exoplanets by blocking the overwhelming light from their parent stars. This allows astronomers to study their properties such as color, temperature, and atmospheric composition.

Note: Spectroscopes and measuring the movement of moons and planets are not specific methods used to detect exoplanets in dark space. Spectroscopes are tools used in various methods of exoplanet detection, while measuring the movement of moons and planets typically applies to our solar system rather than dark space.
