Calculating the number of galaxies in the universe is no small task. Images from the Hubble telescope allowed scientists to calculate that there are around 200 billion visible galaxies. However, some scientists were skeptical of the numbers. So they turned to our own galaxy, the Milky Way, to recalculate. It is surrounded by roughly fifty dwarf galaxies, which the Hubble technology cannot detect. The scientists added the unobservable galaxies into the equation. As it turns out, the number of galaxies in Hubble's images might be closer to two trillion.

Question

Calculating the number of galaxies in the universe is no small task. Images from the Hubble telescope allowed scientists to calculate that there are around 200 billion visible galaxies. However, some scientists were skeptical of the numbers. So they turned to our own galaxy, the Milky Way, to recalculate. It is surrounded by roughly fifty dwarf galaxies, which the Hubble technology cannot detect. The scientists added the unobservable galaxies into the equation. As it turns out, the number of galaxies in Hubble's images might be closer to two trillion.

Pick the answer below.

The comparison of the two sets of Hubble images supports the new scientific theory about the size of the universe.
Pick the answer below.

The description of the sequence of events illustrates the difficulty in calculating the number of galaxies.

Answer 1

The last option, "The description of the sequence of events illustrates the difficulty in calculating the number of galaxies" is the correct answer. The passage presents a sequence of events that demonstrate the complexities and challenges of calculating the number of galaxies in the universe. This effectively conveys the author's message that the task is not easy and requires multiple steps and considerations.
