Radio Silence at Omega Centauri: No IMBH Detected in the Core
Overview In a landmark effort to test one of astronomy’s long-standing hypotheses, researchers scanned the heart of Omega Centauri, the Milky Way’s most massive and luminous globular cluster, for signs of an intermediate mass black hole (IMBH). Despite expectations that a compact, unseen object might lurk at the cluster’s center, the latest radio observations found…

Radio Observations Find Nothing at Omega Centauri’s Heart
A Giant Puzzle at the Heart of Omega Centauri Omega Centauri, the Milky Way’s most massive and luminous globular cluster, has long captivated astronomers. Containing roughly ten million stars packed into a relatively compact region, it offers a natural laboratory for studying stellar dynamics, black hole formation, and the evolution of ancient stellar systems. Earlier…

Astronomers Unveil the Strange Physics Behind Ghostly Radio Relics in Space
The Mystery of Ghostly Radio Relics Across the vast expanses between galaxies lie galaxy clusters — gravitationally bound structures containing thousands of galaxies, dark matter, and a hot, tenuous plasma. In some of the most dramatic cosmic events, these clusters collide in slow-motion mergers that last hundreds of millions of years. From these colossal interactions…

How Record-Breaking Black Hole Collision Could Redefine ‘Forbidden’ Giants
Introduction: A Collision That Defied Expectations In a discovery that challenges long-held beliefs about black holes, scientists have traced the origins of the most massive black hole merger yet observed. The collision involved two black holes whose sizes were once considered nearly impossible within standard models. This breakthrough not only identifies how such giants could…

Interstellar Comet 3I/ATLAS Emits First-Ever Radio Signal—But Not From Aliens
What Happened: A Landmark Detection from 3I/ATLAS In a surprising—but scientifically grounded—development, astronomers announced the first-ever radio signal associated with the interstellar comet 3I/ATLAS as it journeyed through the inner solar system. The signal, detected as the comet approached its halfway point on its one-way voyage, instantly sparked popular curiosity about the possibility of intelligent…

Milky Way Radio View: Unprecedented Cosmic Panorama
Incredible Depth from a Unique Perspective We can’t see the entire Milky Way from within it, yet astronomers have long sought a view that travels beyond the limits of optical light. A new milestone in radio astronomy delivers exactly that: an unprecedented radio view of the Milky Way, painstakingly constructed over more than 40,000 hours…

Unprecedented Milky Way Radio View: 40,000 Hours to Build
Introduction: A New Perspective on the Milky Way A startling new image of our own galaxy emerges not from optical light, but from radio wavelengths. An unprecedented Milky Way radio view took more than 40,000 hours to construct, blending data from multiple radio telescopes into a single, coherent portrait. This week’s space photo of the…

Unprecedented Milky Way Radio View Takes 40,000 Hours to Build: Space Photo of the Week
Overview: A Radio Window into Our Galaxy Humans have long wondered what the Milky Way looks like when viewed from the inside out. Since we inhabit one of its spiral arms, imaging the entire galaxy in a single photograph is impossible. Instead, astronomers piece together a mosaic of radio signals captured from Earth and space-based…

First Radio Signal from 3I/ATLAS: OH Absorption Reveals Hydroxyl Molecules
Overview: A Possible Milestone in Interstellar Chemistry In a development that could reshape our understanding of interstellar chemistry, MeerKAT, the 64-dish radio telescope array operated by the South African Radio Astronomy Observatory, announced observations suggesting absorption lines from hydroxyl (OH) radicals in the light from the interstellar object 3I/ATLAS. While preliminary and awaiting independent verification,…

First Radio Signal from 3I/ATLAS: OH Absorption Reveals Interstellar Chemistry
New Findings: OH Absorption from 3I/ATLAS Reported by MeerKAT In a groundbreaking development for radio astronomy, the MeerKAT array in South Africa has reported the detection of radio absorption lines attributable to hydroxyl radicals (OH) from the interstellar object known as 3I/ATLAS. Operated by the South African Radio Astronomy Observatory (SARAO), MeerKAT’s observations are shedding…
