A black hole by the name of AT2018hyz surprised researchers in 2021 when it started ‘burping’ up material three years after a Tidal Disruption Event (TDE) – a phenomenon that occurs when a black hole consumes a nearby star. This event was captured by the Very Large Array (VLA) radio telescope in New Mexico while studying the TDE of AT2018hyz.

Black holes are well-known for releasing light during a TDE, yet we have only detected it rather quickly after consuming a star. Researchers were surprised that the black hole had three years of radio silence before emitting any light. Even more fascinating, the star matter was recorded at 50% the speed of light – compared to the expected 10% speed of light the star matter usually is recorded at.  

The next step for black hole researchers is exploring other TDEs years after their fruition to determine if this is a common occurrence. Want to learn more about black holes and this delayed emission of light? Click on the links below!
