"Astronomers find a radio galaxy whose black hole launched jets on four separate occasions" — Phys.org · Science & Medicine
Astronomers have identified a —a galaxy with a at its center—that launched powerful jets of plasma on four distinct occasions, rather than the usual single or continuous outburst. This is an unusual finding because are typically thought to be either one-time events or steady; the evidence of multiple separate eruptions suggests the black hole's activity turned on and off repeatedly, offering new insights into the episodic nature of supermassive black hole behavior. The discovery was made using high-resolution radio observations.
The claim is reported by Phys.org, a reputable science news outlet, based on a new astronomical study (likely a peer-reviewed paper or research release). The provenance tier indicates a named primary source, and the reporting appears to closely follow the original findings, though the exact journal or preprint has not been cited in the snippet. The claim's solidity is high given the reputable secondary source and the availability of specific observational evidence.
