ASTRONOMICAL DISCOVERY
CHAPTER I - URANUS AND EROS
CHAPTER II - THE DISCOVERY OF NEPTUNE
CHAPTER III - BRADLEY’S DISCOVERIES OF THE ABERRATION OF LIGHT AND OF THE NUTATION OF THE EARTH’S AXIS
CHAPTER IV - ACCIDENTAL DISCOVERIES
A lively series of six short lectures invites listeners to step behind the telescope and uncover the real stories behind famous sky‑watching triumphs. Rather than the romantic image of a lone astronomer stumbling across a new planet, the author shows how careful calculation, persistent observation, and a dash of serendipity all play a part. With a conversational tone and occasional witty asides, the narrative makes 19th‑century scientific adventure feel immediate and relatable.
The chapters travel from the early puzzlement over Uranus and the curious asteroid Eros, through the dramatic hunt for Neptune, to Bradley’s subtle measurements of light aberration and Earth’s nutation. Later talks explore chance discoveries, the long‑term rhythm of sun‑spots, and the puzzling shifts in the Earth’s latitude, each illustrated with period plates and anecdotes from the Yerkes and Oxford observatories. Listeners will come away with a clearer sense of how astronomers turn data, luck, and curiosity into lasting knowledge.

Best known as a gifted popularizer as well as a working scientist, this British astronomer helped shape modern star-mapping from photographs and also made important contributions to seismology. His career linked Greenwich, Oxford, and the wider international scientific world of the late 19th and early 20th centuries.
