Andy's Object.
In 2020, scientist Ziteng Wang , nicknamed Andy, was the first to discover the strange radio signals, which probably originate from the direction of the center of the galaxy.
The signals seem to switch on and off randomly, and no one has any idea what is emitting them. Scientists at the University of Sydney have tried to identify the object. They have examined all possible wavelengths, from infrared to optical radiation and X-rays. But nothing.
There are several explanations for what could emit such radio waves. But so far, none of the systems we know fit. Both normal stars and neutron stars should have been visible.
The scientists agree that the object must have a strong magnetic field and is probably rather small. The problem is: they are unaware of any astronomical body that possesses all the necessary properties.
Perhaps the mystery isn't so great after all. Science's task is to investigate and ultimately explain the inexplicable. Everything we know was explained at some point. Therefore, it's absurd to suddenly assume the existence of communicative aliens simply because we can't determine the source of a radio signal.
