When astronomers investigate the most distant galaxies they see evidence that?
When astronomers investigate the most distant galaxies, they find evidence that the universe was much younger and more active in its early stages. Observations of these galaxies reveal higher rates of star formation and interactions, suggesting that they were in a more chaotic and dynamic state. Additionally, the light from these galaxies has taken billions of years to reach us, allowing astronomers to study the evolution of galaxies over cosmic time. This research helps to deepen our understanding of the universe's formation and the processes that shaped its structure.
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.
Do Astronomers use microwaves to learn about the structures of galaxies?
they usually use super computers
Diameter of the universe?
With current technology, astronomers are able to detect objects (galaxies) out to about 14 billion light years from us in every direction. We don't know what's farther than that.
What is the name of a sicentist that studies celestial bodys?
An astronomer studies celestial bodies, which include stars, planets, moons, comets, and galaxies.
Billions of years ago galaxies existed in?
Galaxies. They are just about the same now as they were then. 14 Billion years ago, astronomers believe that the "Big Bang" created matter from energy, which is how they believe galaxies were formed.
Who thought of galaxies?
astronomers did
How do astronomers group galaxies into three types, according to their characteristics?
Astronomers group galaxies into three types based on their characteristics: spiral galaxies have arms that spiral out from a central bulge, elliptical galaxies are oval-shaped with no distinct structure, and irregular galaxies have a chaotic and asymmetrical shape.
Will astronomers do all the redshifts of the 100 billion galaxies in the universe?
Perhaps in the future astronomers will do all the redshifts of the 100 billion galaxies in the universe.
If light from galaxies is redshifted what can astronomers conclude about galaxies?
That the galaxy is moving away from us.
How do astronomers know that the Sun is located in a local bubble formed by a supernova?
There is no answer
Will astronomers measure all the distances of the 100 billion galaxies in the universe?
It is possible that someday astronomers will measure all the distances of the 100 billion galaxies in the universe.
Why do astronomers theorize that most of matter in galaxies and clusters of galaxies is dark matter?
most of the mass in a cluster of galaxies is invisible, which provides astronomers with the strongest evidence that the universe contains a great amount of DARK MATTER

How many galaxies do astronomers believe there are?
Billions. (rounded)
How galaxies discovered?
They were discovered by astronomers using telescopes.
Will astronomers measure all the sizes of 100 billion galaxies in the observable universe?
It is possible that astronomers will measure all the sizes of 100 billion galaxies in the observable universe.
