Ah, honey, galaxies do have structures that orbit a supermassive black hole at their center, kind of like a cosmic Ballet... but let's be real, those swirling stars and gas take their own sweet time moving around like they're in traffic on a Monday morning. Trust me, it's worth the wait just to watch the cosmic drama unfold!
Just as the planets and asteroids in our solar system orbit the Sun, held in place by the Sun's gravity, the aggregation of matter in the center of our galaxy exerts a gravitational attraction on the stars of the Milky Way. This includes several smaller galaxies and clusters relatively nearby, such as the Small and Large Magellanic Clouds (two satellite galaxies).Our Sun and its planets are in the "Orion Arm" of the Milky Way, and we are about 27,000 light-years from the galactic center, which likely contains a supermassive black hole.
Black holes are found in the center of galaxies because they are formed from the remnants of massive stars that have collapsed under their own gravity. These black holes have such strong gravitational pull that they can attract and consume nearby matter, including stars and gas, which makes them grow in size over time. This process can lead to the formation of supermassive black holes at the center of galaxies.
Black holes are found at the center of galaxies because they are formed from the collapse of massive stars. When a star runs out of fuel and explodes in a supernova, the core can collapse into a black hole. In the case of galaxies, the black holes at the center are believed to have grown over time by consuming surrounding gas and stars, becoming supermassive black holes. These supermassive black holes play a key role in shaping the structure and evolution of galaxies.
Not all galaxies contain a black hole at their center. Some galaxies, like our own Milky Way, do have a supermassive black hole at their center, while others do not. The presence of a black hole in a galaxy depends on various factors such as the size and age of the galaxy.
Some bodies in space that emit light include stars, galaxies, and active galactic nuclei. Stars emit light through nuclear fusion in their cores, while galaxies and active galactic nuclei emit light from the energy produced by supermassive black holes at their centers.
The galactic centre is the central region of a galaxy. Most, if not all galaxies have a supermassive black hole at their centre.
The center of many galaxies is suspected to house a "supermassive black hole". The black hole may even weigh more than all the stars in that galaxy combined. Spiral galaxies are more likely to contain a supermassive black hole.

Yes, many galaxies have supermassive black holes at their centers.
Galaxies that emit much more radiation (different types of radiation) than a typical galaxy. This actually happens in the galaxy's center, so it's more accurate to talk about an active galactic nucleus. The active galactic nucleus is believed to be caused by a black hole. From Wikipedia: " The radiation from AGN is believed to be a result of accretion of mass by a supermassive black hole at the centre of its host galaxy."
Not every galaxy has a black hole at its center. While many galaxies do have supermassive black holes at their centers, there are also galaxies that do not have black holes.
It's not "galaxy stars", but galaxies, that have the black holes at their center.All, or most, galaxies have a giant black hole at their center.
Not all galaxies, but it is believed that the majority of galaxies have central black holes.
The black hole Sag A* is considered to be at the center of our galaxy.
A supermassive black hole is a huge black hole, usually in the center of a galaxy. All or most galaxies are expected to have such supermassive black holes. Such a galactic black hole typically has over a million times the mass of our Sun; the largest (in large galaxies) have billions of times the mass of our Sun. The black hole in the center of our own galaxy (the Milky Way) is associated with the object Sagittarius A*, and it has a mass estimated at 4 million solar masses.
Not all galaxies have black holes in their centers, but many large galaxies, including our own Milky Way, are believed to have supermassive black holes at their centers.
