Question

question 5
what was the significance of the hubble deep field observations.
it discovered a massive black hole
it found very few galaxies
it discovered the first quasar
it found a large number of spirals, elliptical and irregulars galaxies

Explanation:

The Hubble Deep Field (HDF) observations captured a tiny, seemingly empty patch of sky for 10 days, revealing thousands of galaxies across different cosmic epochs. It showed a large diversity of galaxy types (spirals, ellipticals, irregulars) and provided insights into galaxy evolution. The first quasar was discovered earlier (1963), massive black holes were not the primary HDF finding, and it found many galaxies (not few).

Answer:

it found a large number of spirals, elliptical and irregulars galaxies
