As we look up at the starry sky, countless celestial bodies silently peer down upon us. Most of these have been there for billions of years as stellar processes slowly unfold, starting from their birth until their final demise. Light from other celestial objects, though long vanished, has only recently reached us. In other instances, swift changes in the sky occur at timescales as short as seconds or minutes, like when a dwarf star momentarily flares up or when a human satellite crosses the field of view.

My team has been searching for objects that may have vanished. As an unexpected result of our searches, we found cases where multiple star-like objects (transients) appeared and vanished in a small image within an hour, and even more peculiarly, two of our brightest cases happened in July 1952, coinciding in time with the 1952 Washington D.C. UFO flyovers. But what have we actually found, and how do these two events potentially link to one another?
