For example, the distance between the centers of two black holes in galaxy clusters distant from each other and the gap between cell walls in a living organism differ on a vast scale, despite their sharing of common structures at the atomic level.

New data from the Chandra X-ray Observatory indicates that this distorted supernova remnant potentially hosts the youngest black hole in our galaxy.

Besides revealing clues about the lost galaxy, the black hole itself, called HLX-1 (Hyper-Luminous X-ray source 1), is scientifically interesting, researchers said.
Measurements undertaken with two space-based X-ray telescopes imaged the black hole at the centre of galaxy NGC 1365.
They focused their efforts on NGC4526, mapping out the movements of the molecules at various distances from the galaxy's central black hole.
If that finding is confirmed, it would make the black hole the youngest known in the Galaxy.

This supermassive black hole lies at the center of galaxy NGC 1277, which is about 220 million light years away from Earth.

But despite being millions of times more massive than our own Sun, the black hole at the centre of our galaxy would be relatively small in cosmic terms.
Like virtually every other galaxy in the universe, the Galaxy NGC 4845 has a central black hole.

Other key objectives include trying to observe important new details about black holes, and attempting to study a galaxy that produces up to 100 suns a day.
Unlike the sexy, metal HTC One, the Galaxy remains a polycarbonate, white or black plastic phone.

"The fact that there's a very young cluster of stars indicates that the intermediate-mass black hole may have originated as the central black hole in a very low-mass dwarf galaxy, "Sean Farrell, of the Sydney Institute for Astronomy in Australia, said in a statement.
An active galaxy is a star system with a humongous black hole at its centre.
In the galaxy NGC 1277, astronomers have discovered a black hole with the mass of 17 billion suns.
FORBES: Astronomers Find One Of The Biggest Supermassive Black Holes Yet
Like a fossil hinting at a long-gone animal, a black hole is offering clues about a now-destroyed galaxy that may once have existed around it.
The team calculated a distribution of masses and space velocities for some 35, 000 individual free-floating black holes thought to lie within that region of the galaxy.
FORBES: Free-Floating, Nearby Black Holes Detectable By Decade's End, New Study Reports
Using an array of 10 powerful radio telescopes, aimed at the galaxy BL Lacertae, the researchers studied a black hole just as it was sending forth a blazar jet.
The Hubble Space Telescope recently spied a cluster of young blue stars surrounding a rare mid-weight black hole that suggests the black hole was once at the center of a dwarf galaxy.
Despite the fact that it is probable that a black hole lurks at the centre of our Milky Way galaxy, astronomers still know very little about these celestial monsters which vacuum up almost everything in their path, even light.
The black hole is located in a globular cluster associated with a galaxy named NGC 4472, some 55 million light-years away.

Our own galaxy, the Milky Way, has a colossal black hole at its core, too, which is some three million times the mass of our Sun.

Even more fascinating, the supermassive black hole is about 14% of the total mass of the galaxy.

" He adds a bit later: "That we live in a large spiral galaxy with very little central stellar bulge and a modest central black hole may be a clue to the type of galaxies best suited to life: ones that did not spend their pasts building colossal black holes and fighting the demons unleashed in the process.
There are tens of thousands of black holes, which can be formed by massive dying stars, in our galaxy, Levin said.
The black hole, bigger than a billion suns, has collided with the smaller galaxy which it is now devouring in a display of celestial fireworks.
Dark blue-black fruits, complex layers of spice and blackberry, some cassis, just an abundant galaxy of taste pleasures.

The violent encounter would have stripped away most of the dwarf galaxy's stars, but it also could have compressed the gas around its central black hole, triggering a new wave of star formation.
