Abstract

The reorganization of the astronomical community during the late nineteenth and early twentieth centuries, due to the rise of astrophysics, was seen by some scientists as an opportunity to join an international community of prestigious researchers. This was the case of astronomers such as Josep Comas i Solà, who publicly argued with Eugène Michel Antoniadi during the first decades of the twentieth century about the veracity of astronomical observations and theoretical conclusions on Mars and Jupiter. Their priority claims and public disputes have to be understood in a new context that provided an exceptional opportunity for amateur and professional astronomers both to play an active role in the most interesting scientific debates of these years and to gain prestige, legitimacy and power
