Here is a realistic passage that supports the sentence:

On January 9, 1970, a team of astronomers at the Palomar Observatory in California made a groundbreaking discovery. While surveying the night sky, they spotted a small, distant asteroid that would later become known as 1983 Bok. Although it would take eight years for the asteroid to be officially designated, the team's initial observations marked the first time this celestial body had been detected. The discovery was met with excitement, and the team began to track the asteroid's orbit, laying the foundation for further research and study.
