ESPRESSO: The Spectrograph to Find Earth 2.0

Recommended Posts

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?

No.  I think there are more variables than size that have to be taken in to account. 

Welcome to the forum.

Earth 2.0? what is this, an computer generated simulation like The Matrix, but with an upgrade.

Earth 2.0 is the place we haven't ****ed up yet.
