The agency says on its website that Canada’s FGS “points to bright stars in deep space to stabilize the Webb telescope so images are clear.”
The shroud of a dying star, the Astral Ring Nebula, seen in the video, is a “planetary” or disc-shaped, planet-like nebula. It is located regarding 2500 light years from Earth.
In the images of the nebula revealed last week, two stars can be distinguished: a red one which has just died and which is at the origin of the nebula, and a white one, “bright and still alive”, explained to the To have to Nathalie Ouellette, in charge of scientific communications for the James Webb telescope in Canada and coordinator of the Institute for Research on Exoplanets at the University of Montreal.
