A trail of newborn stars has now been detected in its wake, stretching an incredible 200,000 light-years in length.
\u201cTwo's company, and three's a crowd... even when it comes to black holes!\n\nHubble detected evidence of a "runaway" black hole that was ejected from its host galaxy after a tussle between it and two other black holes. Find out more: https://t.co/hEs3i7MUma\u201d
As ever with black holes, the reason for this unusual activity isn’t exactly clear. However, the findings were reported in the Astrophysical Journal Letters by a team led by Yale astronomy professor Pieter van Dokkum.
The findings were also observed in NASA's Hubble Space Telescope, with Dokkum’s research suggesting that when the black hole comes into contact with gas it sparks new stars into life as the gas cools down.
“What we’re seeing is the aftermath," Dokkum said. "Like the wake behind a ship, we’re seeing the wake behind the black hole.”
