What is a galaxy with a black hole in the center called?

What is a galaxy with a black hole in the center called?

The Milky Way
The Milky Way hosts its own supermassive black hole at its center known as Sagittarius A* (pronounced “ay star”) that is more than four million times as massive as our sun.

What is a group of black holes called?

“Abyss,” “crush,” “haunting” and “chasm” came up frequently. So did (less grimly) “Hawking,” after the man who did so much to understand them, as well as “riddle,” “mystery,” “mass” and “binge.” Other favorites: a “scream” of black holes, an “oblivion” and a “mosh pit.”

What is the black hole in the middle of the universe?

The supermassive black hole that lurks at the center of our galaxy, called Sgr A*, has a mass of about 4 million times that of our Sun. A black hole is a place in space where gravity is so strong that neither particles or light can escape from it.

What are black hole stars?

In many ways, a black hole acts like an ideal black body, as it reflects no light. Black holes of stellar mass form when very massive stars collapse at the end of their life cycle. After a black hole has formed, it can continue to grow by absorbing mass from its surroundings.

How do we call a group of stars?

A constellation is a group of stars that appears to form a pattern or picture like Orion the Great Hunter, Leo the Lion, or Taurus the Bull. Constellations are easily recognizable patterns that help people orient themselves using the night sky. There are 88 “official” constellations.

What do you call the center of a black hole?

At the center of a black hole is what physicists call the “singularity,” or a point where extremely large amounts of matter are crushed into an infinitely small amount of space.

How big is the black hole at the Galactic Center?

Scientists at the Max Planck Institute for Extraterrestrial Physics in Germany using Chilean telescopes have confirmed the existence of a supermassive black hole at the Galactic Center, on the order of 4.3 million solar masses.

How big is a neutron star compared to a black hole?

The calculated mass of the dark object is 8-10 solar masses; much too massive to be a neutron star which has a limit of about 3 solar masses – hence black hole. This is of course not a proof of a black hole – but it convinces most astronomers.

Which is the best candidate for a black hole?

X-ray sources are candidates for black holes because matter streaming into black holes will be ionized and greatly accelerated, producing x-rays. A blue supergiant star, about 25 times the mass of the sun, was found which is apparently orbiting about the x-ray source.
