At the invitation of those responsible for the Naves Biodiversity Atlas, members of the Limousin astronomy club revealed the mysteries of the sky and the stars.
Those responsible for the Biodiversity Atlas have done things well. On a moonless night and a clear sky, enthusiasts from the Limousin astronomy club showed the hundred or so people present what happens above our heads at night.
As a preamble, enthusiasts suggested observing the sun. Everyone was surprised to discover a ball enveloped in flames (the protuberances) which, little by little, disappeared on the horizon, to make way for the stars.
Constellation, nebulae, galaxies
The day-night transition was taken advantage of by educational astronomers to present the celestial environment and give some technical explanations on the functioning of telescopes and the organization of the universe.
A short course on how to be careful when observing the sun, some explanations on the set of mirrors in telescopes, and the arrangement of the planets and their satellites shed light on the observations that followed.
The discussion first focused on the stars, whose arrangement can constitute a constellation. Grouped together in large numbers, the stars then form nebulae (easily visible clouds of gas), or galaxies, including the Milky Way.
Then, the planets, telluric or gaseous, were presented: those easily visible, even without material, like Venus; or Saturn, for which the telescope made it possible to discern the ring.
The preparation completed, time was made for the show. By moving from one telescope to another, everyone learned about this celestial environment and enjoyed better understanding this illuminated universe.
