What are the 4 components of a galaxy?
From Earth, the Milky Way seems to be a heavenly mist because the stars blur together. Little do most people know, the stars are broken into four main parts. The four main parts are the disk, the nuclear bulge, the halo, and the galactic corona.
What is a component of all galaxies?
What are the parts of a galaxy? A galaxy contains stars, gas and dust. In a spiral galaxy like the Milky Way, the stars, gas, and dust are organized into a “bulge,” a “disk” containing “spiral arms,” and a “halo.” Elliptical galaxies have a bulge-like central region and a halo, but do not have a disk.
What are the three main components of a galaxy?
The three major components of the Milky Way are referred to as the disk, bulge, and the halo. 2. The three types of active galaxies are Seyfert Galaxies, Radio Galaxies, and Quasars.
Whats are galaxy called?
The term “Milky Way”, a term which emerged in Classical Antiquity to describe the band of light in the night sky, has since gone on to become the name for our galaxy. Like many others in the known Universe, the Milky Way is a barred, spiral galaxy that is part of the Local Group – a collection of 54 galaxies.
What shape is an irregular galaxy?
An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy. Irregular galaxies do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.
What type of galaxy do we live in?
Milky Way Galaxy
What are the characteristics of an irregular galaxy?
An irregular galaxy is the catchall name given to any galaxy that does not neatly fit into one of the categories of the Hubble classification scheme. They have no defined shape nor structure and may have formed from collisions, close encounters with other galaxies or violent internal activity.
What are 3 characteristics of spiral galaxies?
Spiral galaxies have three main components: a bulge, disk, and halo (see right). The bulge is a spherical structure found in the center of the galaxy. This feature mostly contains older stars.
What are some characteristics of each galaxy?
Each galaxy has its own collection of stars, planets, black holes, neutron stars, moons, nebulae, asteroids, comets, and dark matter. Our galaxy is a barred spiral galaxy and is called the Milky Way. It has large spiral arms with a bulging disk and bar of stars in the center.
Which type of galaxy is the oldest?
Elliptical galaxies
How big are black holes?
about 78 billion miles
What is the true shape of a black hole?
spherical
What happens if you go inside a black hole?
Of course, no matter what type of black hole you fall into, you’re ultimately going to get torn apart by the extreme gravity. No material, especially fleshy human bodies, could survive intact. So once you pass beyond the edge of the event horizon, you’re done. There’s no getting out.
How close to a black hole is dangerous?
26,000 light years

What are the dangers of a black hole?
These black holes are dark most of the time, but when their gravity pulls in nearby stars and gas, they flare into intense activity and pump out a huge amount of radiation. Massive black holes are dangerous in two ways. If you get too close, the enormous gravity will suck you in.
Can a black hole kill Superman?
But if superman enters black hole , using method-1 , then there are very low chances that superman might survive , and pass easily through the black hole. Yet , the chances are very-very-very less , even equal to 1/infinity(not equal to zero).
