While attending Queen's College, Edmund Halley had his first research publications published.

At the age of seventeen, Edmund Halley enrolled at Oxford University. His appointment as Astronomer Royal there in 1676 there. He had the idea that he should learn more about astronomy, so he started studying and practicing.

He was appointed John Flamsteed's protégé while still a college student, the Astronomer Royal. His first research articles on the orbits of certain planets were published in the third year of his undergraduate studies. At Oxford, he continued his observations, and by the time he was 20 years old, he had submitted the Royal Society an explanation of a better method for calculating planetary orbits.

In addition to publishing studies on the solar system and sunspots, Halley made significant observations at Oxford, including an occultation of Mars by the moon. He was able to make the following deduction after carefully observing Jupiter and Saturn: Jupiter is moving at an ever-increasing speed, whereas Saturn is moving at a decreasing pace. Astronomers began to question the stability of the Solar System as a result of his first scientific finding.
