Project history
From 2015 to 2027
Twelve years from idea to opening
The project began as a student request, and it took twelve years to carry it from the first idea to opening to the public.
May 2015 · The very beginning
The first ideas take shape.
An initial request to install a dome at Toulouse III University, and first discussions about siting it on the Maison des Étudiants et des Personnels.
February 2018 · A fresh start
The project properly begins.
First presentation to a committee of Toulouse III Paul Sabatier University, followed by the call for tenders for the building in September.
2019 · Opening to schools
A decisive first step.
The observatory’s primary purpose shifts as it opens to school groups. A first grant from the science and engineering faculty, a first crowdfunding campaign over the summer, and a planning application in September.
2020 · The grants
The project turns professional.
Internal reform of the association and the first substantial grants, from the Occitanie region and the Catalyses foundation. The instruments are settled, first purchases committed, the dome plans finalised and the observatory’s governance defined.
2021 · The name
The first instrument purchases.
A first direct university grant, acquisition of the secondary instruments and first equipment tests. A second crowdfunding campaign in October and November, and the name is chosen: Jocelyn Bell Observatory in Toulouse.
2022 · The training courses
The first operational phases.
First training courses, first projects run with the observatory, and the instruments are named.
2025 · The inauguration
The dream becomes real.
The main telescope is delivered, then the dome and all the instrumentation are installed in March. The observatory physically exists and the first tests begin. Official inauguration on Thursday 11 December, with the partners.
2026 · Commissioning
The observatory comes to life.
Commissioning, testing and improvements throughout the year. Open day on 16 April, with Jocelyn Bell in attendance.
January 2027 · Opening to the public
The observatory is ready to welcome you.
Opening to the public on 1 January: observing sessions, school and group visits, and slots open to scientific projects.
