Astronomers have spotted a runaway supermassive black hole, seemingly ejected from its home galaxy and racing through space with a chain of stars trailing in its wake.

The researchers discovered the runaway black hole as a bright streak of light while they were using the Hubble Space Telescope to observe the dwarf galaxy RCP 28, located about 7.5 billion light-years from Earth.
Follow-up observations showed that the streak measures more than 200,000 light-years long — roughly twice the width of the Milky Way — and is thought to be made of compressed gas that is actively forming stars. The gas trails a black hole that is estimated to measure 20 million times the mass of the sun and is speeding away from its home galaxy at 3.5 million mph (5.6 million km/h), or roughly 4,500 times the speed of sound.

To determine this isn't what they observed, van Dokkum and the team investigated this streak and found it didn't possess any of the telltale signs of an astrophysical jet. While astrophysical jets grow weaker as they move away from their source of emission, the potential supermassive black hole tail actually gets stronger as it progresses away from what seems to be its galactic point of origin, according to the researchers. Also, astrophysical jets launched by black holes fan out from their source, whereas this trail seems to have remained linear.
The team concluded that the explanation that best fits 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.

The ignorance of that statement is astounding, considering their reported observations. Does anyone else see what they discovered? Presuming, of course, that their observations are accurately reported.
It continues to amaze me that so-called 'scientists' create their own echo chambers - in many cases institutionally, e.g., 'climate', 'big bang', etc.
"Small minds."

Just hope its not headed in our direction.
Star-jacking is illegal!...................
I’m trying to figure out if “the size of 20 million suns” is a measure of mass or volume.
if “the size of 20 million suns” is a measure of mass or volume.

Either way it’s a lot.
That reference is typically used for stellar object size.
e.g., Red Giant (10x sun), Super Giant (100x sun), etc.
An AU (astronomical unit) is far larger than their observations (150 million km) for size reference.
I hope it is.
Let’s just get it over with.
