How did Edwin Hubble measure the distance to the Andromeda Galaxy?
He applied the period-luminosity relation to Cepheid variables.
Is the Hubble galaxy the closest major galaxy to our own?
There is no galaxy called the Hubble Galaxy
How did Edwin Hubble's discovery that the Andromeda galaxy was far away of our own galaxy contribute to astronomers' knowledge about the size of the universe?
Prior to Hubble's discovery scientists generally believed that our galaxy was the entire universe. Hubble found that the Andromeda galaxy was, then called the Andromeda Nebula, was not a part of our galaxy but a galaxy unto itself far beyond the edge of the Milky Way. This discovered demonstrated that the universe is much larger than scientists have believed.
What has the Hubble telescope discovered?
The Hubble telescope looked deep into space and discovered the Galaxy field. When then realised that it is obvious we are not alone.
How far can Hubble telescope see?
This has been answered before but here it is again. The Hubble telescope with the light-collecting power of the W. M. Keck Telescopes can see 13 billion light years away based on the furthest detected galaxy to date. In comparison looking up into the sky on a very clear night, the Triangulum Galaxy can sometimes be seen by the naked eye. This is a distance of 3.14 million light years. The Andromeda Galaxy is also sometimes visible. This is a distance of 2.5 million light years.

Edwin Hubble demonstrated that distant galaxies existed by measuring which type of stars?
what is the type of star used by the Hubble to measure the distance to other galaxies.
What is the type of star used by Hubble to measure the distance to other galaxies?

Who measure the distance of Andromeda nebulae?
Hubble
Is the Hubble galaxy the closest major galaxy to our own?
There is no galaxy called the Hubble Galaxy
What did the astronnmer Edwin Hubble discover about the relationship between the distance of a galaxy and the rate at which it is receding?
He discovered that the farther away a galaxy was, the faster it was moving away from Earth.
How quickly is the universe expanding?
The farther away a galaxy, the faster it will go away from us. Check the Wikipedia article on "Hubble's Law" for more details. According to the article, the currently accepted value for the "Hubble constant" is 74.2 ± 3.6 (km/s)/Mpc. That is to say, if a galaxy is at a distance of 1 Megaparsec, on average our distance from this galaxy will increase at a rate of about 74 km/s. For a galaxy at 2 Megaparsec distance, the speed would increase at twice this value, etc.
He originally suggested that galaxies are moving farther away He also suggested that the distance of a galaxy is proportional to its recessional speed who is He?
Edwin Hubble.
According to Hubble's law the farther away a galaxy is?
According to Hubble's Law, the farther away a galaxy is the, faster it is moving away
What is the mathematical equation for calculating the expansion of the universe?
v = H0D Where v is the velocity at which a galaxy moves away from us, and D is its distance. With H0 being the constant of proportionality (the Hubble constant) between the distance D to a galaxy and its velocity v.
What is is hubbles law?
Hubble's Law states that (more or less) the distance to a galaxy is a constant multiple of the distance to that galaxy. For example, if one galaxy is moving away from us at three times the speed of another galaxy, then that means it is also three times as far away. The Law indicates that the Universe is expanding and had a beginning. Before Hubble's Law, many astronomers thought that the Universe did not have a beginning (it always existed).
What was Edwin Hubble's equation?
Hubble's equation states that the velocity at which various galaxies are receding from the Earth is proportional to their distance from us.The law is often expressed by the equation v = H0D, with H0 the constant of proportionality (the Hubble constant) between the distance D to a galaxy and its velocity v. The SI unit of H0 is s-1 but it is most frequently quoted in (km/s)/Mpc, thus giving the speed in km/s of a galaxy one Megaparsec away. The reciprocal of H0 is the Hubble time.
