- Why is it difficult to determine where cosmic rays come from?arrow_forwardTwo students in a science club argue with each other regarding the concept of Redshift. The statements made by the students are given as follows: Student 1: When the absorption maxima shift towards longer wavelengths then it is called the Redshift. Student 2: The decrease in wavelength due to the Doppler effect is known as the Redshift. Which of the above statement/s is/are correct? (a) Both student 1 and student 2 are true. (b) Only student 1 is true. (c) Only student 2 is true. (d) Both student 1 and student 2 are false.arrow_forward2.90 x 106 nm : K Find the wavelength (in mm) of maximum intensity of the cosmic microwave background radiation observed today.

Why is it that astronomers of the mid-20th century only seemed to detect approximately 1/3 of the neutrinos from the Sun that they had expected to?arrow_forwardAstronomers can determine the heat of various areas of the universe by making observations about energy they emit. Gamma rays can be found in areas where there is a lot of star formation occurring. What would you guess about the temperature of these areas? Explain why.Do you think there would be a lot of particles present? Explain why.arrow_forward
- The Andromeda Galaxy, M31, is the closest large spiral galaxy to our Milky Way. When we look at its chemical spectrum, we see that its hydrogen alpha emission line (Hα) has an observed wavelength of λobs = 655 nm.-Calculate z, being careful with the sign.-How fast is it moving in km/s?-Is it redshifted or blueshifted? Is it moving towards or away from us? answer to three significant figures.arrow_forwardRadio astronomy involves wavelengths much longer than those of visible light, and many orbiting observatories have probed the universe for radiation of very short wavelengths. What sorts of objects and physical conditions would you expect to be associated with emission of radiation at very long and very short wavelengths? (Select all that apply.) very long wavelengths cold cold gas cosmic background radiation nuclear reactions ++ Opulsars solar corona very high-energy processes very short wavelengths cold gas cosmic background radiation nuclear reactions pulsars solar corona very high-energy processesarrow_forwardAssume that the radiation coming from Andromeda is all due to solar-like stars (MV, = 4.83). How many stars are there in the Andromeda galaxy according to this approximation?arrow_forward
- 38. The Cosmic Microwave Background is remarkable in many ways. Let's illustrate this by personalizing the CMB a bit. a) Imagine that the Earth is a sphere with a radius equal to its actual equatorial radius (The radius of Earth at the equator is 3,963 miles (6,378 kilometers). If the radius of the Earth is assumed to be constant to the same level of uniformity as the temperature fluctuations of the CMB—that is, to one part in 100,000—then how high would the highest mountains be relative to the mean surface radius of the Earth? b) Calculate the ratio of the age of the Universe when the CMB was created and the age of the Universe today (in late 2021). If a person is 20 years old, What was their age relative to their current age adopting that fraction? Give the result in hours.arrow_forwardAssuming stars to behave as black bodies stefan-boltzmann law to show that the luminosity of a star is related to its surface temperature and size in the following way: L = 4(3.14)R^2oT^4 where o= 5.67 ×10^-8 Wm^-2 K-4 is the stefan- boltzmann constant. Then use this expression together with the knowledge that the sun has a surface temperature of 5700k and radius 695 500km to calculate the luminosity of the Sun in units of Wattsarrow_forwardCosmic Microwave Background 8.
