The group identified a brand-new radio source (white square) in the center of the cluster (red circle) Credit: Paduano et al. A worldwide team of astronomers has actually produced the most delicate radio image ever of a globular cluster, an ancient ball of tightly-packed stars.The image is of the second brightest globular cluster in the night sky– understood as 47 Tucanae– and was produced by a team led by the Curtin University node of the International Centre for Radio Astronomy Research (ICRAR) in Western Australia.The scientists likewise detected a previously undiscovered radio signal from the center of the cluster.The research study was released over night in The Astrophysical Journal.Astronomer Dr. Arash Bahramian, from ICRARs Curtin University node, says star clusters are an ancient antique of the early Universe. Bahramian said the ultra-sensitive image was developed from more than 450 hours of observations on CSIROs Australia Telescope Compact Array (ATCA), in Gomeroi Country.It is the deepest, most sensitive radio image ever assembled by any Australian radio telescope.Dr. He stated imaging it in such fantastic detail permitted astronomers to find an extremely faint radio signal at the center of the cluster that had not been discovered before.Lead author Dr. Alessandro Paduano, from ICRARs Curtin University node, said the detection of the signal was an exciting discovery and could be attributed to one of two possibilities.Hear about what astronomers found inside 47 Tucanae– the 2nd brightest globular cluster in the night sky.
