Astronomers have sighted a supermassive black hole traveling through space that appears to have been ejected from its host galaxy.
Researchers observing the dwarf galaxy designated RCP 28, roughly 7.5 billion light years away from our solar system, noticed an aberrant streak of light via the Hubble telescope. The “streak” appears to be a collection of stars being dragged out of their home galaxy by the immense gravitational force of a black hole.
The “runaway” black hole is the first of its kind to be observed, and appears to have been ejected from its original galaxy.
“We found a thin line in a Hubble image that is pointing to the center of a galaxy,” Professor Pieter van Dokkum of Yale University, the lead author of the study, said. “From a detailed analysis of the feature, we inferred that we are seeing a very massive black hole that was ejected from the galaxy, leaving a trail of gas and newly formed stars in its wake.”
The “stellar tail” in its wake is 200,000 light-years long, twice the diameter of our Milky Way galaxy.
The black hole in question is believed to be 20 million times more massive than the Sun, and it is traveling away from RCP 28 at a rate of 3.5 million miles per hour, roughly 4,500 times the speed of sound.
Black holes are celestial bodies where matter has been condensed and concentrated to such an extent that even light cannot escape its gravitational pull — as such, black holes are almost impossible to observe directly, and are usually spotted via their effects on nearby stars and nebulae (clouds of interstellar gas).

Star-jacking by a Black Hole?...................
Black holes?
Dark matter?
When are they going to ban racist astronomy?
Black hole ejected from its community. Interstellar racism, obviously
(Raises hand)
Um... is it getting closer or further away from here? (Granted... still 1.66 million years away even if heading straight for us, but...)
7.5 billion light years away and the can confidently state the black hole is 20 million times more massive than our sun...
I fight hard not to be taking in by these morons... Sensationalism drives the reporting class to the extreme...
It’s actually well-established astronomical science to measure the mass of a black hole at great distances.
One can measure the mass of a black hole by tracing the motion of the gas and dust near the black hole that is being pulled-on by the mass of the black hole.
This can be done at many wavelengths, such as by measuring the positions of stars which orbit near a black hole at optical wavelengths.
At radio wavelengths, we can measure the emission from a specific type of emission from the water (H2O) molecule, which occurs at radio wavelengths, to trace the motions of the gas circling the black hole.
So....how does a black hole...supposedly 20 million times more massive than the Sun and pretty much the densest thing imaginable, get “ejected” from anywhere?
This is someone’s postulation, based on incomplete information and knowledge and the lack of an understanding of the dynamics involved. Yet it makes it into a “news” article.
Name it “Meghan”
Hmmm...
Why haven’t we received a “Black” alert?
Often get those “Silver” or “Amber” alerts...
Not a joke. I bet they change the name at some point. The other day, I heard on an HGTV show the term “primary” bedroom because Master was deemed offensive.
Well, they cite astronomers, researchers & a professor from Yale university. Are all these lacking complete information or the dynamics involved? If so, it’s a sad state of affairs. Of course, it could just be an idiot journalist, but I repeat myself.
My answer to your question is, imho, yes.
They are guessing about dynamic events happening 7.5 billion years ago and 7.5 billion X 6 trillion miles away.
The people you list are paid to do this work and, while I am sure they are dedicated and enjoy their work, exotic theories - iow, guessing - is the best we can expect in these circumstances. Wobbling starlight reception and variations in a color spectrum and so forth is scant criteria to base much of anything on, much less these events as they are contending - events separated by such fantastic time and distance.
I am still interested in how a massive black hole can be pushed around - ejected from a galaxy, they said - and by what force.
