Astronomers observed black hole event AT 2024tvd, where a star was torn apart far from a galaxy center, revealing the fastest-changing radio signals ever recorded. This rare find offers new insight into black hole movement and challenges old theories about their galactic locations.

Rare Black Hole Catastrophe Observed
Astronomers have reported a rare event called AT 2024tvd, where a rogue black hole destroyed a star roughly 2,600 light-years away from its home galaxy’s center. The Zwicky Transient Facility initially spotted the event in optical wavelengths, but further observations revealed the remarkable off-center location. Such occurrences are known as tidal disruption events (TDEs), when a massive black hole tears a star apart due to overwhelming tidal forces. These catastrophic moments are often studied to improve our understanding of black hole physics and their environments, with details available in authoritative outlets like Space.com and Nature.

Record-Setting Radio Signals
The event produced radio emissions unlike any previously observed. Two separate peaks in radio waves—one at about 131 days, the next at 194 days—were detected by astronomers. The bursts, observed at both centimeter and millimeter wavelengths, are the most rapidly changing radio signals ever recorded from a black hole event. Scientists attribute this to dynamic outflows or jets of material, either occurring in succession or as complex interactions with the surrounding space debris (NASA).
