Javier Gorosabel has been, and still is, part of the Calar Alto Observatory, and with his departure, we lose something of what this place is. He was always between the most enthusiastic and productive users of any of Calar Alto telescopes, in both instrumentation and scientific projects. But, most of all, here, at this mountain, we learned and laugh with him. Although it will take some time, as we have our hearts shrunk and feel like the stars are less bright, we are sure that we will continue learning his science and laughing with him.
On behalf of the Calar Alto Observatory, we share the grief to his family and with all who knew him.
