What are the 4 Types Of Galaxies? Pictures, Facts And Information
What are the 4 Types Of Galaxies? Pictures, Facts And Information! Galaxies are vast systems of space held together by gravity and composed of stars, dust, interstellar gas, stellar remnants, and dark matter. No one knows how big the universe is, but our planet Earth is in the Milky Way Galaxy of the Solar System.
The word galaxy is taken from the Greek word. There are about 70,000 million stars in the universe as far as we know from scientists around the world. Today, in this article, we will discuss four types of galaxies. Science-loving friends stay with us and keep reading the article.
4 Types of Galaxies 2024:
Here, we give you 4 Types of Galaxies. Let’s take a look.
- Spiral Galaxies
- Elliptical Galaxies
- Lenticular Galaxies
- Irregular Galaxies
4 Types of Galaxies 2024 Full Details:
Here, we give you 4 types of Galaxies in full detail. Let’s see.
Spiral Galaxies:
Spiral galaxies are considered a recognized galaxy type. They are visually stunning and intricately shaped. Looks like a pancake-like disc or a giant spinning pinwheel of stars. According to scientists, the presence of a bar indicates that the galaxy has reached full maturity.
Elements of Spiral Galaxies:
- Halos
- Old Stars
- Star Cluster
- Dark Matter
2 Types of Spiral Galaxies:
- Regular spiral
- Barrier spiral
Characteristics of Spiral Galaxies:
- Vast spiral arm
- Central inflation
- Flat rotating disks of stars
- The black hole at the centre of the galaxy
- Galactic halo of matter.
Elliptical Galaxies:
Elliptical galaxies are oval. But it can be pointed out that they are different from spirals. These galaxies usually contain little gas and dust. The kshatras in it rotate randomly around the centre. They are older than spiral galaxies because they lack the gas to form new stars.
Lenticular Galaxies:
What scientists mean by a lenticular galaxy is that it is a type of galaxy intermediate between spiral and elliptical. Some standard features of lenticular galaxies are central bulges, typical disks, old stellar populations, and less frequent star formation. But it has no arms. Scientists have different opinions about its evolution. Some scientists believe these galaxies are old spirals whose arms have faded.
Irregular Galaxies:
When a galaxy is neither spiral nor elliptical, a new shape appears to be an irregular galaxy. Instead of a regular, orderly shape, it forms a strange shape. Irregular galaxies consist of stars, gas, and dust.
