Astronomers have discovered a runaway supermassive black hole in an extremely active dwarf galaxy located about 7.5 billion light-years from Earth.[0]<\/a><\/sup> The streak observed measures over 200,000 light-years long and the black hole itself is estimated to be 20 million times the mass of the Sun.[1]<\/a><\/sup> It is also observed to be moving incredibly fast, with a speed of 3.5 million mph.[2]<\/a><\/sup> Follow-up observations also showed that the streak is made of compressed gas that is actively forming stars.<\/p>\n

It is hypothesized by the team that the galaxy, which shows an irregular shape and vigorous star formation, likely had three black holes in the past, suggesting a recent collision.[3]<\/a><\/sup> As the lightest black hole was ejected to create the bright trail, the remaining two were kicked out in the opposite direction with somewhat lower velocity.[3]<\/a><\/sup> This suggests that the black hole could have been ejected due to a galactic merger where a third black hole ousted this one.<\/p>\n

However, the only way to detect a black hole is when they interact with other objects.[4]<\/a><\/sup> Astronomers are uncertain as to how many black holes of varying masses exist in the Milky Way, leaving them in the dark.[5]<\/a><\/sup><\/p>\n

Moreover, the team concluded that the best explanation for the streak is a supermassive black hole blasting through the gas that surrounds its galaxy while compressing that gas enough to trigger star formation in its wake.[2]<\/a><\/sup> Images captured with Keck Observatory's NIRC2 instrument and adaptive optics show the gas and dust structures in the galactic center, including G objects and X7.[6]<\/a><\/sup> The team believes that the black hole is an intermediate-mass black hole and could be more plentiful there than astronomers previously thought.<\/p>\n

The findings are the first estimate of X7's mildly eccentric orbital path and most robust analysis to date of the remarkable changes to its appearance, shape, and behavior.[7]<\/a><\/sup> Researchers in the future have a promising target to investigate as they search for one of the most colossal missing pieces of the universe.[8]<\/a><\/sup> More observations from other telescopes are required to verify that the end of the strange streak is actually a black hole.<\/p>\n
