Concept explainers
The observation Hubble saw from the light coming from the glowing hydrogen atoms in distant galaxies.
Answer to Problem 11RQ
Hubble observed the glow in the MUSE observations and concluded that it was emitted by gas, which was 11.5 to 12.8 billion light years from us. The observation found that the universe was expanding and also ten thousand new galaxies were seen there.
Explanation of Solution
In the MUSE observations, the Hubble Ultra Deep field showed hundred of galaxies where hydrogen glow was superposed. They found that the glow was everywhere and was coming from hydrogen gas in the distant Universe.
The gas found in the observation was not an easy task, the scientists used tricks to saw the clear view of the faint gas clouds.
After staring the light about 270 hours and recording the incredibly fainting light of distant galaxies, they showed the glow everywhere in the image. It got brighter around the galaxies. The patchy view in the Hubble telescope showed faint galaxies.
The glow found in the MUSE observation was emitted by gas that was about 11.5 to 12.8 billion light-years from the Earth.
Conclusion:
Therefore, Hubble observed the glow in the MUSE observations and concluded that it was emitted by gas, which was 11.5 to 12.8 billion light years from us. The observation found that the universe was expanding and also ten thousand new galaxies were seen there.
