Astronomers in Australia picked up a strange radio signal in June 2024 — one near our planet and so powerful that, for a moment, it outshined everything else in the sky. The ensuing search for its ...

Cosmic reionization denotes the transformative epoch when the first luminous sources emerged, ending the cosmic dark ages by ionising the pervasive neutral hydrogen. This period, which encompasses ...

Cosmic radio pulses repeating every few minutes or hours, known as long-period transients, have puzzled astronomers since their discovery in 2022. Our new study, published in Nature Astronomy today, ...
