According to Hubble and law galaxies are retreating from Earth at a speed that is proportional to their?
According to Hubble's Law, galaxies are retreating from Earth at a speed that is proportional to their distance from us. This means that the farther a galaxy is, the faster it appears to be moving away, indicating an expanding universe. This relationship is often expressed with the formula ( v = H_0 \times d ), where ( v ) is the recession velocity, ( H_0 ) is the Hubble constant, and ( d ) is the distance to the galaxy. This observation supports the Big Bang theory and our understanding of cosmic expansion.

What do the farthest galaxies in the universe appear to be doing according to Hubble's law?
Mating. If you even know what Hubble's Law is you know the answer to this question.
Who devised the classification system for galaxies?
In 1962, astronomer Edwin Hubble decided to classify galaxies according to a logical scheme. he eventually decided to classify them according to their shape. Today, galaxies are divided into four main groups: spiral, barred spiral, elliptical, and irregular.
What is the name of the telescope that they use to see galaxies?

What is the type of star used by Hubble to measure the distance to other galaxies?

Who showed that other galaxies existed?
The astronomer Edwin Hubble provided evidence in the 1920s that other galaxies existed beyond our own Milky Way. By observing Cepheid variable stars in the Andromeda Galaxy, he demonstrated that it was a separate galaxy located far outside our own. This discovery revolutionized our understanding of the universe's scale and confirmed the existence of other galaxies.
What was hubble named after?
The Hubble Space Telescope was named after Edwin Hubble, an American astronomer that discovered that galaxies outside of the Local Group are moving away from us at speeds proportional to their distances.

What is it when galaxies move away at a speed proportional to their distance?
This phenomenon is known as Hubble's Law, which describes the relationship between the distance and the velocity at which galaxies are moving away from us. It is a key piece of evidence for the expansion of the universe.

What is Edwin Hubbles key contributes and evidence on galaxies?
Edwin Hubble is renowned for demonstrating that galaxies exist beyond our Milky Way, fundamentally reshaping our understanding of the universe. His key contributions include the classification of galaxies and the formulation of Hubble's Law, which shows that the universe is expanding, with galaxies moving away from us at speeds proportional to their distances. This discovery provided strong evidence for the Big Bang theory and established the field of extragalactic astronomy. Hubble's observations, particularly with the Hubble Space Telescope, have been pivotal in advancing our knowledge of the structure and evolution of the cosmos.
According to Hubbles law galaxies are retreating at a speed that is proportional to their?
I'm not convinced that your proposition is correct. I realize that cosmologists use a lot of simplification in their descriptions, for friendly reasons, but I always prefer to keep things fairly straight. It is my reading of Hubble that he postulated that remote galaxies were receding -- at the time they emitted the light which we are now receiving -- from us at a speed which was proportional to the distance from where they were then to where we are now. How one interprets the concept of distance, in view of the separately postulated "expansion of space" and time-dependence of the "scaling factor" is obviously now a compounding, related issue, which lay outside Hubble's purview. Hubble's law does not specify, based upon the observed redshift (whether non-Doppler or not) what is (i.e. is now) the distance between us and the galaxy. It is considered simplest to assume that the velocity of separation is and continues radially uniform, and therefore has increased during the time it took the light to reach us. If you need to know the current (our observing time) location of the remote galaxy and the velocity of its separation from us now, you will need to apply further calculations to the Hubble data.

What are the contributions of Edwin Hubble?
Edwin Hubble made significant contributions to astronomy, most notably through his discovery of the expansion of the universe, which led to Hubble's Law. He demonstrated that distant galaxies are moving away from us, with their speed proportional to their distance, providing strong evidence for the Big Bang theory. Hubble also played a crucial role in classifying galaxies and establishing the field of extragalactic astronomy. His work fundamentally changed our understanding of the universe and its structure.
