Could entire stars simply vanish?! One of the strangest mysteries in astronomy isn't about black holes or aliens. It's about stars that seem to disappear without a trace.
In this conversation, astronomer Beatriz Villarroel explains the VASCO (Vanishing & Appearing Sources during a Century of Observations) project and one of its most astonishing discoveries: **nine star-like objects that appeared and disappeared simultaneously on a single photographic plate**, long before the satellite era.
We cover:
• Why hundreds of "missing stars" had to be investigated one by one.
• The automated search pipeline developed by Enrique Solano to analyze decades of astronomical data.
• Why about 600 disappearing objects demanded closer inspection.
• The famous image containing nine transient objects that still challenges conventional explanations.
• What these discoveries could mean for astrophysics, observational astronomy, and the search for rare cosmic phenomena.
