Imagine a black hole so fast it could travel from Earth to the Moon in just 14 minutes – except instead of lurking in a galaxy’s core, it’s been kicked out and is now streaking through intergalactic space. Scientists have discovered a runaway supermassive black hole, 20 million times the mass of the Sun, plowing through gas and leaving behind a 200,000-light-year-long trail of newborn stars – twice the size of the Milky Way!
NASA’s Hubble Space Telescope spotted it completely by accident. 
Rather than consuming everything in its path, this black hole is compressing gas and igniting star formation in a phenomenon never seen before.
So, how did this cosmic juggernaut get flung into deep space? Astronomers believe a rare triple black hole encounter is to blame. That’s a violent event where one black hole got ejected at high speed, while the other two possibly remained as a duo, flying off in the opposite direction.
This discovery is one-of-a-kind, but who knows? Now that we’ve seen one, it’s only a matter of time before we find more rogue black holes carving paths through the cosmos.
