Scientists believe that the more distant galaxies formed?
Scientists believe that galaxies formed earlier in the universe's history, with the most distant galaxies being some of the first to have formed after the Big Bang. Studying these distant galaxies can provide insights into the early stages of galaxy formation and evolution.
Who discovered blue shift?
The blue shift phenomenon was discovered by the American astronomer Edwin Hubble in the 1920s. He observed that the light from distant galaxies appeared shifted towards the blue end of the spectrum, indicating that these galaxies were moving away from us. This discovery provided crucial evidence for the expansion of the universe.
The visible part of distant galaxies is the galaxies'?
The visible part of distant galaxies is the collection of stars, gas, and dust within the galaxy. These components emit light that reaches our telescopes, allowing us to observe and study the structure and properties of the galaxies.
Who discovered red shift in the starlight from distant galaxies?
Vesto Slipher and Edwin Hubble were the first who discovered a red shift in nearby Galaxies and as telescopes improved the formula could be applied to more distant Galaxies. The instrument that determines red or blue shifts is called a Spectroscopy. Ans. 2 The person who discovered (and explained) red-shift in the light from other galaxies was Vesto Slipher. Edwin Hubble, using Slipher's observations, realised that the amount of red-shift was proportional to the distance of the galaxy being observed. He formalised this as "Hubble's Law". This was what led cosmologists to the conclusion that the Universe is expanding. (see * below) The instrument that shows a spectrum is a spectroscope; that which measures it is a spectrometer and that which records it is a spectrograph. The instrument that measures red-shift of a distant galaxy can be anything from a travelling microscope to a ruler, depending on the quality of the photographs. Spectroscopy is the name of a set of processes, like photography or cookery , not any particular instrument. * The larger stars/galaxies are visible from further away. The larger stars/galaxies have a larger red shift without regard to their distance from us. (re: larger means more gravity means more red shift)
What did hubble discover as a result of studying the red shift of distant galaxies?
Hubble discovered that the redshift of distant galaxies indicated that the universe is expanding, which provided evidence for the Big Bang theory. This observation also led to the realization that galaxies are moving away from each other, with those farther away moving faster, suggesting an overall expansion of the universe.
Why do scientist study the light coming from distant galaxies?
They study distant galaxies because they want to know whats out in other galaxies and how many planets it has
Who is an scientist that discovered existence of galaxies beside your own?
Edwin hubble
How far away are the most distant galaxies?
That is impossible to answer because scientist don't know ALL the galaxies.
Who found the galaxies?
who discovered the galaxies who discovered the galaxies
The visible part of distant galaxies is the galaxies what?
The "nucleus".
What scientist discovered the three main types of galaxies?
spiral galaxies elliptical galaxies and irregular galaxies
Scientists believe that the more distant galaxies formed?
Scientists believe that galaxies formed earlier in the universe's history, with the most distant galaxies being some of the first to have formed after the Big Bang. Studying these distant galaxies can provide insights into the early stages of galaxy formation and evolution.
Why scientist don't expect to find galaxies that have large blue shift?
This should be because of the fact that the Universe is expanding. You see a blueshift when objects move closer to you. Other than super distant galaxies, most galaxies will not measure to be a blueshift due to the fact that the Universe is expanding and accelerating.

Why do scientists study distant galaxies to learn about galaxies?
Scientists study distant galaxies to understand the formation, evolution, and properties of galaxies over time. By observing galaxies that are far away, they can explore the universe at different epochs and gain insights into how galaxies have changed and evolved since the early universe. Studying distant galaxies also helps scientists refine theories about the laws of physics and the nature of the universe as a whole.
