In 1181, Chinese astronomers spotted a flash — likely the merger of two white dwarfs. Modern observations of the Pa 30 nebula barely pick up a radio signal. This means the explosion’s energy was extremely low, or particle acceleration works differently. The discovery forces us to rethink the nature

Astronomers trained a neural network to search for fast radio bursts without complex data preprocessing. On the repeating source FRB 20121102A, it found 5,927 signals—three times more than before. Analysis showed that the burst energies always split clearly into two classes, and this property is unc

A powerful radio pulse from a distant galaxy revealed eight fading bursts—like a cosmic bell that tolled and then went silent. This is the first observation of fading rhythms in such signals, and it reveals the trembling of the magnetic cocoon around the ultra-dense core of a dead star. From the rhy

To unravel the nature of fast radio bursts (FRBs), astrophysicists applied methods from nonlinear dynamics and constructed the Pincus–Lyapunov diagram, comparing them with pulsar glitches, solar flares, and earthquakes. It turned out: repeating FRBs form a compact cluster on the border between stoch
