- Machine learning improves accuracy in identifying transient astronomical phenomena from historical images.
- Transients decrease when Earth blocks sunlight (shadow deficit) and increase around dates of nuclear testing (nuclear window).
- A trained model with AUC 0.81 validated transients, showing significant links to nuclear windows and shadow effects, supporting their existence.
