The largest-ever black hole jets ever seen hint that these cosmic monsters may play an even more significant role in shaping galaxies than previously thought.

The newly discovered black hole-driven jets extend over 7 megaparsecs or 23 million light-years.

Such jets are vast blasts of radiation and particles that erupt out of supermassive black holes. They can last for millions of years, reshaping the cosmos as they change how matte

In any globular cluster, all its stars formed at the same time, from the same cloud of gas. The Milky Way has around 150 known globular clusters; these objects are excellent tools for studying, for example, the history of the Universe, or the dark matter content of the galaxies they orbit.

The energetic streams are together 23 million light-years in length—roughly as long as 140 Milky Way galaxies lined end to end

The largest known black hole jets, 23 million light years across, have been discovered in the distant universe. This pair of particle beams launched by a supermassive black hole is over a hundred times larger than our galaxy,

There's only one thing it could be: a black hole, one with a petite size that's smack bang in the middle of a mysterious void in the data known as the lower mass gap. Named G3425, it might have a lot to teach us about tiny black holes according to an analysis.
