New interferometry observations from the CHARA Array have captured unprecedented real-time images of stellar nova explosions, revealing they're far more complex than scientists thought. These 2025 findings show multiple interacting material outflows instead of simple bursts—one nova displayed perpendicular gas flows, while another exhibited a dramatic 50-day ejection delay.

By linking these high-resolution structures with Fermi telescope gamma-ray data, researchers can now explain how powerful shock waves form during these events. This breakthrough transforms our understanding of novae from basic explosions into dynamic, varied cosmic laboratories.
