Its story

A blue, variable beacon in Vela, set at a colossal distance —so far that its light has been crossing the cosmos for hundreds of thousands of years. When it set out, the first sapiens were still chiselling stone tools and articulate language was barely beginning to awaken. A B-class star of enormous luminosity, its brightness oscillates slowly, reminding us that even celestial giants pulse to the rhythm of their own gravity.
