Early astronomers had poor instruments for observing the heavens. Large practical optical telescopes have only existed for about 350 years, and until the 20th century, there was no concept of "radio" at all - far less "radio astronomy". The idea of the "Big Bang" was ridiculed right up until Penzias and Wilson discovered the background cosmic radiation, for which they won the Nobel Prize.

What term do astronomers use to describe a galaxy that has a jumbled scattering of stars?
Astronomers refer to a galaxy with a jumbled scattering of stars as an "irregular galaxy." These galaxies lack a defined shape or structure, distinguishing them from spiral or elliptical galaxies. Irregular galaxies often contain young stars, gas, and dust, and they can be the result of gravitational interactions or collisions with other galaxies.
What is the name of a sicentist that studies celestial bodys?
An astronomer studies celestial bodies, which include stars, planets, moons, comets, and galaxies.
Who looks through telescopes at the stars?
Astronomers typically look through telescopes at the stars to study celestial objects such as planets, stars, galaxies, and other phenomena in the universe. They use telescopes to gather data and make observations that help expand our knowledge of the cosmos.
Rocks are to geologists as stars are to?
Rocks are to geologists as stars are to astronomers.
Why do astronomers believe that globular clusters are made of old stars?
Astronomers believe the globular clusters are made of old stars because of the lack of heavy elements. The heavy element is very abundant in stars like our sun, so the theory is the globular cluster must be older and formed in a more primitive universe.
What are astronomers?
A scientist who studies celestial bodies such as planets, stars , and galaxies.

How does a spectroscope enable astronomers to determine the characteristics of distant stars and galaxies?

Why couldn't early astronomers tell the difference between single stars and the entire galaxies when the looked at the night sky?
Unless you have a extremely powerful telescope, a galaxy and a star look almost the same.
What is the name is people who studies the stars?
People who study stars are called astronomers. They observe and analyze celestial objects and phenomena, including stars, planets, galaxies, and more, to better understand the universe.
What is the name of a sicentist that studies celestial bodys?
An astronomer studies celestial bodies, which include stars, planets, moons, comets, and galaxies.
What is the unit that astronomers use to measure the differences between stars and other galaxies?
They do not use units: they use the fact that stars are not galaxies. For example, you don't use units to measure the difference between children and countries.
What type of scientist studies the Solar System stars and galaxies?
Collectively they are called Astronomers and Astrophysicists. Either professionals or amateurs.There are many types of astronomers, defined by how they study the stars. The most well-known are those that use optical telescopes followed closely by those that use Radio-telescope to pick up wavelengths other than visible light. there are many others and many other ways to collect data on the galaxies and stars.Astrophysicists are astronomers and may also collect direct data, yet they are more interested in the working behind the data. They deal in physics and theories of the galaxies.
What is the name of the people who study stars?
The people who study stars are called astronomers. They explore celestial objects, including stars, planets, and galaxies, to understand the universe's structure and behavior. Astronomers use various tools, such as telescopes, to observe and analyze astronomical phenomena.
How can astronomers survey at least 100 billion galaxies to make a 3D map of the observable universe?
No, because it will be impossible for astronomers to survey at least 100 billion galaxies (each with 100 billion stars) to make a 3D map of the observable universe.
What kind of cluster is a tight group of older stars in the halo of spiral galaxies called?
I think you are describing a "globular cluster", which are associated with older stars by most astronomers.
Who looks through telescopes at the stars?
