All large galaxies are suspected to have supermassive black holes at their centers. But recently scientists found one distant galaxy, which is seemingly missing its black hole.

A black hole, to be precise - more massive than a billion suns. You see, nearly every large galaxy appears to harbor a supermassive black hole at its center.

'Recoiling' black hole in a nearby star cluster keeps slipping detection, baffling scientists-
Scientists have discovered a black hole at the centre of a bright cluster of a distant galaxy that has baffled them for its 'recoiling' nature. The enormous black hole keeps slipping through the astronomers' nets. The galaxy, at the core of the cluster Abell 2261, about 2.7 billion light-years from Earth, should have a large central black hole, weighing as much as 3 billion to 100 billion suns, according to scientists.
As material falls into a black hole's maw, it accelerates and heats up tremendously, emitting lots of high-energy X-ray light. Now, scientists have conducted an even deeper search for X-rays using Chandra X-ray Observatory, that even considered the possibility that the black hole was knocked toward the vicinities after a monster galactic merger.

Supermassive black holes are thought to lurk at the hearts of most, if not all, galaxies. Our own Milky Way has one as massive as 4 million suns, for example, and M87's — the only black hole ever imaged directly — tips the scales at a whopping 2.4 billion solar masses.
The big galaxy at the core of the cluster Abell 2261, which lies about 2.7 billion light-years from Earth, should have an even larger central black hole — a light-gobbling monster that weighs as much as 3 billion to 100 billion suns, astronomers estimate from the galaxy's mass. But the exotic object has evaded detection so far.
Deepening Astronomical Mystery: On the Hunt for a Missing Giant Black Hole
This missing black hole should be in the enormous galaxy in the center of the galaxy cluster Abell 2261, which is located about 2.7 billion light-years from Earth. This composite image of Abell 2261 contains optical data from Hubble and the Subaru Telescope showing galaxies in the cluster and in the background, and Chandra X-ray data showing hot gas (colored pink) pervading the cluster. The middle of the image shows the large elliptical galaxy in the center of the cluster.

Astronomers think this active galactic core is creating a cosmic show reminiscent of the light and dark columns seen bursting through the clouds at sunset.

A team of researchers traced the rays and resulting shadows back to a supermassive black hole at the center of IC 5063. Because the blackhole is gobbling up nearby material at a rapid rate, its food piles up around it like too much water going down a small drain. This cosmic whirlpool causes the circling material to heat up and glow around the otherwise black hole.
Galaxy May Be Missing Its Supermassive Black Hole, Says NASA
Astronomers are still puzzling over why they aren't detecting a supermassive black hole (SMBH) in the center of the bright cluster galaxy Abell 2261 (A2261-BCG). Despite recent observations with NASA's Chandra X-ray Telescope and NASA's Hubble Space Telescope, there's little evidence for an expected colossal black hole in a galaxy in the cluster's core.
The observations, detailed in a paper appearing in a journal of the American Astronomical Society (AAS), posit that this galaxy underwent a merger with another galaxy in the past, which could have caused a newly formed larger black hole to be ejected. Or says NASA, their observations were simply not sensitive enough to pick up the signatures of such a colossal black hole.
Supermassive black hole at center of distant galaxy has gone missing
Experts have been left astonished after a supermassive black hole which was thought to be in the middle of a distant galaxy has gone missing.
The bright cluster galaxy A2261-BCG appears to have lost its black hole and some scientists think it could now be floating through space.

It means a powerful force in the galaxy may have ejected the supermassive black hole and sent it somewhere far away.
Almost every galaxy in the Universe is thought to have a giant black hole at its centre, including our galaxy which is the Milky Way.
Bad Astronomy | A supermassive black hole in a galaxy in Abell 2261 is missing
You'd think a black hole with the mass of a decent-sized galaxy would be easy to find. But then, you're not looking for the one in the center of a galaxy in Abell 2261 .
Abell 2261 is a ridiculously huge cluster of galaxies about 2.7 billion light years away from us. It has thousands of galaxies in it, and astronomers measure its total stellar content to equal the mass of a quadrillion (10 15 ) Suns.

Like most big clusters, it has a big galaxy sitting in its center. It doesn't have an official name, but astronomers call it Abell 2261 BCG, for Brightest Cluster Galaxy. In general, galaxies in the centers of clusters are the biggest and brightest; they're literally at the bottom of the cluster's gravity well, and everything falls into them. Mergers with smaller galaxies are common, so the central galaxy usually grows huge.
