This study of science is called Astronomy; the study of the night sky, planets, galaxies, and other celestial objects.
Clusters
Vast collections of stars are called galaxies.
Because the universe as a whole is expanding, distant galaxies are moving away from us. As a result, electromagnetic waves emitted by those galaxies experience what is known as a red shift. Their wavelengths get longer.
Scientist believe the galaxies known as irregular galaxies are the result of several different outcomes, for instance the merger of a pair of galaxies, or a wondering galaxy that strays to close to a neighboring galaxy. There are many different explanations for why irregular galaxies occur.
cuz they are explorers

The study of solar system like star ,moon planets, galaxies and sun is called Astor geography
Astronomy.
They are called elliptical galaxies.
irregular galaxies
By using a telescope to study stars, planets, and galaxies.
The study of space is called astronomy. Astronomy involves the observation and analysis of celestial objects, including stars, planets, comets, and galaxies, as well as phenomena such as supernovae and black holes.
A group of galaxies is called a cluster.
