Hydrogen (and a little Helium).
Scientists know that elliptical galaxies do not contain many young stars because observations have shown that they have mostly older stars with low levels of interstellar gas and dust needed for star formation. This lack of gas and dust suggests that these galaxies have exhausted their supply of materials for forming new stars and are no longer actively forming young stars.
A stellar nursery.
No. They are made mainly of stars and planets. The stars and planets came from gas and dust.
A group of stars that forms from a large amount of dust and gas coming together is called a star cluster. These clusters can be categorized into two main types: open clusters, which are loosely bound and contain young stars, and globular clusters, which are densely packed and contain older stars. The gravitational forces pull the dust and gas together, leading to the formation of stars.
The belt of stars consisting of dense clouds is known as the Milky Way Galaxy. It is a barred spiral galaxy that contains a vast number of stars, gas, and dust, forming a luminous band when viewed from Earth. The dense clouds of gas and dust, often referred to as nebulae, play a crucial role in the formation of new stars within the galaxy.
irregular galaxy
None. A nebula is a cloud of gas and dust that can contain young stars, but a nebula is not a planet by any means.
The Milky Way galaxy is composed of various components, including interstellar dust, gas, and young stars. The dust and gas primarily reside in the galaxy's spiral arms, where they serve as the building blocks for star formation. Young stars are often found in these regions, indicating ongoing stellar birth processes. Together, these elements play a crucial role in the galaxy's evolution and the lifecycle of stars.
Milky way
This represents a galaxy, which is a massive collection of stars, gas, dust, and other celestial objects bound together by gravity. The Milky Way is an example of a galaxy that contains millions of stars, along with interstellar gas and dust.
A nebula is a cloud of gas and dust in space where new stars are formed. These regions are often characterized by the presence of young, hot stars surrounded by glowing gas and dark dust.

A huge spiraling disk of stars, dust, and gas is called a galaxy. The Milky Way is an example of a galaxy that contains our solar system.
