Question

Galaxies are vast clusters of thousands of millions of stars, planets, gases, and dust, which are held

together by gravity. There are over one thousand million galaxies, and each is a very long way from

its nearest neighbour.

Galaxies were formed during the Big Bang explosion about 15000 million years ago. When this

phenomenon occurred, everything that was in the universe flew out in different directions.

Scientists believe that the galaxies were formed from lumps of matter that resulted. However, the

process is nowhere near complete. The universe is still expanding, galaxies are still moving away

from each other, new stars are still being created.

Galaxies are classified according to their shapes. There are three main types. The most common

type of galaxy is The Spiral. This has several spiral arms radiating out from the centre. Spiral galaxies

have a large cluster of stars in their nucleus. The second type is the Barred spiral. In this type of

galaxy, the spiral arms curve away from the opposite ends of a sort of bar going through the middle

of the nucleus. These contain large amounts of gas and dust as well stars. The third type of galaxy is

electrical. These consist almost entirely of stars and contain very little gas or dust. Some galaxies

have irregular, uneven shapes and cannot be classified.
