ESPRESSO: The Decisive Spectrograph to Find Earth 2.0

[alfa015]

I would like to talk about an instrument that has been sometimes overlooked: ESPRESSO.

As most of you probably know, ESPRESSO is the only current spectrograph able to detect Earth-sized planets.

I think it will be a key instrument for 2 reasons:

1- The majority of the most potentially habitable exoplanets were discovered with the radial velocity method.

2- Only 0.5 % of the Earth-like planets in the Milky Way could be detectable by using transit photometry.

Do you think we will find a nearby Earth 2.0 with ESPRESSO in 2020?
