Each point on the above diagram shows the line-of-sight recession velocity versus distance for a number of distant galaxies. Describe how the recession velocities of galaxies are measured by astronomers. Explain the different techniques used by astronomers to measure the distances to galaxies, and describe how these methods are used to construct the distance ladder.
For the picture below what is the differences of light spectra of different galaxies. compared to a laboratory reference to uses as comparison, or control group. What is the differences between nearby stars and galaxies compared to distant stars and galaxies by using the spectral lines ?

- Please Explain The hotness of stars goes up to millions of degrees Celsius. The coldness of gases can go as low as -273.15 o C. How do you explain the absence of symmetry between hot and cold? Is it possible that there is also a limit to the hotness of any object in the universe? Show your step-by-step solutions.arrow_forwardAstronomy question: Answer correctly and read the questions corretly, this is all one quesiton if done correclty and organized I will write a very nice review about you! 1. How did Edwin Hubble measure the distance to the Andromeda Galaxy? He deduced it from its redshift. He measured its parallax. He used Cepheid variables in the Andromeda Galaxy. He used white dwarf supernovae in the Andromeda Galaxy.arrow_forwardSuppose you want to observe the molecular gas in a galaxy with redshift z using the rotational transition of CO J=4-3. What frequency would you observe this transition at? (Hint: the CO J=1-0 emits a photon at 115.27 GHz, and higher order transitions emit photons with frequencies in multiples of J, e.g., use the knowledge you gained from the problem above). Express your answer as an integer. Values: z = 1.3arrow_forward
- As we discussed, clouds are made of a great many small drops. Really - a great many. Imagine a liquid cloud that fills a volume of 1 km3. The clouds contains 100 drops per cubic centimeter; for the sake of argument assume that each is 10 microns (micrometers) in radius. A. How many drops does the cloud contain? Compare this to a big number - say, the number of stars in the galaxy. B. What mass of water does the cloud contain? Compare this to something big - elephants, trucks, that sort of thing. C. What fraction of the cloud volume is filled with condensed water? One way to approach this is to compare the density of the suspended liquid water to the density of the surrounding air. D. How many 1 mm drizzle drops could you make from all the cloud drops? E. How much energy was released when this water condensed from vapor to liquid? If the water condensed in 20 minutes (a reasonable lifetime for a small cloud), what was the (energy per time)? powerarrow_forwardRead the questions slowly and answer with precise and long details about each of the questions.

- used in the rest of this book. Exercises I Take the diameter AB of the Earth's orbit as 3 x 108 km and consider a star S at a distance d, such that SA = SB and the angle ASB = 2 arcseconds. Calculate d. This is the distance unit of one parsec. Relate it to one light year. 2 Given that the Sun takes ~2 × 108 years to make a circular orbit around the Galactic Centre, staying at a distance of 10 kpc, estimate the mass of the Galaxy contained within the solar orbit, assuming that it is spherical and ignoring any effects of mass lying outside the orbit. (You may use Newtonian dynamics and gravitation.) 3 A galaxy has a visible mass of 101 Mo and a flat rotation curve extending to 25 kpc at the level of 150 km s-1. What is the ratio of its dark-matter mass to its visible mass? 4 Compute the gravitational energy of a pair of colliding galaxies, each of mass 10"Mo, separated by a distance of ~10 kpc and compare it with the energy requirements of a powerful radio source. What conclusion do you…arrow_forwardPart A Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). The star-gas-star cycle will keep the Milky Way looking just as bright in 100 million years as it looks now. This statement does not make sense. The blowouts of gas from the disc will deplete the gas from the disc of the Milky Way in abiut 10 million years This statement makes sense. Disk of the Milky Way consist enough gas to sustain a few billion years of star formation. This statement makes sense. Most of the bright stars of spiral arms have light expentancies significantly greater than 100 million years. This statement does not make sense. The brightest stars of spiral arms of the Milky Way have life expentancies of about 10 million years.
