Exoplanets – the beginning of a new era in astrophysics

A protagonist’s perspective
Oral history interview

Abstract

This oral history interview touches upon important topics like the dynamics of the discovery, in 1995, of 51 Pegasi b – the first extrasolar planet ever found around a normal star other than the Sun – the development of better and better equipment that made it possible, the importance it had in shaping a new community of scholars dealing with this new field of research, and, more at large, the cultural importance it had in overturning our view of the cosmos.
