The mind-bending reality of the deep sky
1888: a century of mapping the faint objects scattered across the night sky culminates in the New General Catalogue.
1923: Andromeda is not a cloud within our galaxy, but another galaxy entirely. What we called the universe was suddenly just one galaxy among countless others.
1996: pointing at tiny patches of empty sky revealed thousands of galaxies, making ours just one among trillions.
The deeper we looked, the bigger the universe became.
