ESPRESSO: The Decisive Spectrograph to Find Earth 2.0

[caballerodiez]

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?

Anybody?

Earth is unique compared to any other planet we have seen so far. In that it has life in abundance.

Whether life arises at random or whether it does not will effect the odds of us ever finding another world like Earth.

So the answer will either be:

 

A: Yes! Because I think Earth worlds appear randomly by accident so we cannot be the only one. Or...

B: Not likely.
