“This discovery is based on more than a decade of HARPS intensive monitoring together with state-of-the-art data reduction and analysis techniques. Only HARPS has demonstrated such a precision and it remains the best planet hunter of its kind, 15 years after it began operations."

Astronomers also anticipate that more temperature exoplanets will be discovered in the coming years, and that future surveys will be able to determine a great deal more about their atmospheres, composition and chemistry. Instruments like the James Webb Space Telescope (JWST) and the ESO's Extremely Large Telescope (ELT) are expected to play a major role.

Not only will these and other instrument help turn up more exoplanet candidates, they will also be used in the hunt for biosignatures in planet's atmospheres (i.e. oxygen, nitrogen, water vapor, etc.). As Bonfils concluded:
