The WMAP satellite got pictures of the universe's faint background temperature. (this is called the Cosmic Microwave Background) This shows us regions*1 pointThat will eventually become empty spaceThat will eventually become cites of stars and planetsWhere other universes could existAreas that there is higher and lower density in the early universe

what is the remnant heat left over from the big bang

What is the cosmic background radiation?the faint glow of light across the night skythe light-energy remnants of the explosion in which the universe was born    the light emitted by supernova explosionsthe radio noise from hot gas in rich galactic clusters

19)The Hubble Space Telescope (HST) is projected to maintain operation until at least 2030, but it has already revolutionized high-resolution imaging of solar-system bodies in visible and ultraviolet (UV) light wavelengths, notwithstanding that only about 6% of the bodies imaged by the HST are within the solar system. NASA researcher Cindy L. Young and colleagues assert that a new space telescope dedicated exclusively to solar-system observations would permit an extensive survey of minor solar-system bodies and long-term UV observation to discern how solar-system bodies change over time. Young and colleagues' recommendation therefore implies that the HST ______ Which choice most logically completes the text?IFRPRAEN-019will likely continue to be used primarily to observe objects outside the solar system.will no longer be used to observe solar system objects if the telescope recommended by Young and colleagues is deployed.can be modified to observe the features of solar system objects that are of interest to Young and colleagues.lacks the sensors to observe the wavelengths of light needed to discern how solar system bodies change over time.

According to the big bang theory, the known universe started 13.7 billion years ago in a hot dense state and expanded explosively. As it expanded, it cooled down to the point where atoms could form. By the force of gravity, these atoms coalesced into gas clouds that eventually became stars. These stars eventually formed young galaxies. Which of the following is true about the current position of the galaxies in the universe? A. The position of the galaxies cannot be predicted. B. The galaxies are now moving closer together. C. The galaxies are now drifting further apart. D. The position of the galaxies is not changing.

The photons in the CMB were emitted when the universe was about 1/1100 of its current size. What was the temperature of the universe at that time? (The present day temperature of the CMB is 2.7 K.)
