Galaxy collisions, which tend to strip gas from spirals, are more common in large clusters.

[102][103][104][105] Its energy density is

The radial velocity curve for a star with an extrasolar planet is shown above. There is a unique center within the Universe that coincides with where the Big Bang happened. , In another scenario, known as the Big Rip, the expansion of the Universe will eventually lead to all matter and spacetime itself being torn apart. 3

00:00 Start 13:47 How do we calculate the habitable zones around other stars? stars in that region are hidden by dark dust clouds. [46][52][100] Later analyses have pointed out that these are the modes most susceptible to foreground contamination from synchrotron, dust, and Bremsstrahlung emission, and from experimental uncertainty in the monopole and dipole. refers to a spherical harmonic, and ℓ is the multipole number while m is the azimuthal number. ≈ Olbers' paradox is an apparently simple question, but its resolution suggests that the universe is finite in age. Y If neither of these scenarios are correct, and the Universe continued to expand at an accelerating rate, the CMB will continue redshifting to the point where it is no longer detectable. What kind of radiation is used to find the location and shape of the Milky Way's spiral arms?

The anisotropy, or directional dependency, of the cosmic microwave background is divided into two types: primary anisotropy, due to effects that occur at the surface of last scattering and before; and secondary anisotropy, due to effects such as interactions of the background radiation with hot gas or gravitational potentials, which occur between the last scattering surface and the observer. What would happen? Free electrons easily interacted with the photons, scattering them. Which star is hotter?

The first-year WMAP results put the time at which P(t) has a maximum as 372,000 years. [54] The third peak can be used to get information about the dark-matter density.[55].

φ Density of energy for CMB is 0.25 eV/cm3[18] (4.005×10−14 J/m3) or (400–500 photons/cm3[19]). Which of the following statements BEST describes cosmic microwave background radiation? The CMB is central to the Big Bang Theory and modern cosmological models (such as the Lambda-CDM model). his question "Where are they?" Which star is more luminous? Compared to a main-sequence star of type O, a main-sequence start of type K is: Suppose that the surface temperature of the Sun were to double.
