CHECK THESE SAMPLES OF The Velocity of a Galaxy
Note however that the mass that one determines by measuring the velocity of a gas cloud or a star in the disk of a spiral galaxy is the mass contained within the circle made by the orbit of that object.... To find the total mass of a galaxy one has to measure the velocity of a gas cloud or star at the edge of the disk of the galaxy.... Very often it is much more convenient to measure the velocity of the gas rather than the stars, especially in the case of the Milky Way....

According to Newtons theory of gravity, if I double the mass of the Sun, by how much should the velocity of the Earth change?... Turn on the gravity force arrow, the velocity arrow and click to show path as well.... Turn on the gravity force arrow, the velocity arrow and click to show path as well.... So the period T is inversely proportional to the velocity (T~1/v).... n the formula for the velocity (or period), the mass M is the mass of which object?...

the velocity of the galaxies varies in respective to their diameter length.... All this was proved during the study of the Milky Way galaxy.... The astronauts believe that the things that exist in the universe are all within the perimeters of our galaxy.... With the measurements, the galaxy is proved to be of a 300000 light years in diameter.... The galaxy also had spiral nebulae that was seen by the use of the telescopes and the clouds which were just like gases were seen in the Milky Way....

The author describes how Edwin Hubble proved that M31 is not a nebula in our Milky Way galaxy and answers why astronomers believe that vast quantities of dark matter surround our galaxy.... This black hole became the nucleus of the galaxy Thanks to this work, Hubble knew that he could use the characteristics of the fluctuating light of Cepheid variable stars to help him calculate the distance to M31.... This proves that M31 is not an open or globular cluster in our galaxy, but rather an enormous separate stellar system—a separate galaxy....

These stars in the background help in the identification of the specific body by illuminating the galaxy.... The paper "Measurement of the Hubble Constant" mentions an American astronomer Edwin Hubble who made an observation every object that is observable in interstellar space has a relative velocity to the earth and to any other similar object, and this relative velocity is observable by Doppler shift.... v = HoD is the mathematical expression of the Hubble law, whereby Ho is the Hubble constant of proportionality between D and the object's velocity, v....
