"Uncovering a Mysterious Radio Signal from an Ancient Star Cluster"

Astronomers have produced the most sensitive radio image ever of the ancient star cluster 47 Tucanae, revealing a previously undiscovered radio signal at its center. The image, created by a global team led by the Curtin University node of the International Centre for Radio Astronomy Research, was compiled from over 450 hours of observations using CSIRO's Australia Telescope Compact Array. The signal could potentially indicate the presence of an intermediate-mass black hole or a pulsar, and the research demonstrates the capabilities of current radio telescopes while hinting at the potential of future telescopes like the SKA.
