William Herschel Discovers the Planet Uranus

March 13th, 1781 244 years ago

William Herschel, an amateur astronomer, discovered Uranus while conducting a survey of stars from his garden in Bath, England. Using a telescope he had made himself, he initially believed he had found a comet due to the planet's faintness and slow movement across the sky. Herschel's finding marked the first time a planet was discovered with a telescope, expanding the known boundaries of our solar system and fundamentally altering our understanding of the celestial realm.

Lexell's Comet Approaches Earth Closely

July 1st, 1770 254 years ago

Lexell's Comet made a remarkable approach to Earth, coming within 0.0146 astronomical units (about 2,180,000 km). Discovered by the astronomer Anders Johan Lexell, this comet was notable for being the closest comet recorded at that time. The sighting sparked great interest and excitement in the scientific community, leading to further study of comets and their orbits. Observers around the world took note of its brilliance as it traversed the night sky, making it a significant astronomical occurrence of the 18th century.

Palitzsch Confirms Halley's Comet Prediction

December 25th, 1758 266 years ago

Johann Georg Palitzsch sighted Halley's Comet, validating Edmund Halley’s earlier prediction of its return. This was the first time a comet's appearance had been forecasted accurately, marking a significant milestone in the study of celestial events. Palitzsch's observation took place in Germany, showcasing the effectiveness of scientific prediction based on earlier observations. Halley's Comet had not been seen since 1682, and Halley’s prediction had drawn considerable attention, making the successful sighting thrilling for astronomers and enthusiasts alike.

Failed Prediction of a Catastrophic Comet Strike

October 16th, 1736 288 years ago

Mathematician William Whiston predicted a comet's approach to Earth, claiming it would strike the planet. The comet, associated with earlier sightings and calculations, was expected to cause widespread devastation. As the predicted date came and went without incident, public interest and scrutiny shifted. Whiston, known for his translation of Josephus, faced scrutiny from peers and the scientific community regarding his methods and predictions.

Halley's Prediction of a Solar Eclipse

May 3rd, 1715 309 years ago

A total solar eclipse was observed across northern Europe and northern Asia, accurately predicted by astronomer Edmond Halley. The eclipse occurred on May 3, 1715, capturing the attention of scientists, astronomers, and the general public. Halley, who had gained fame for his work in celestial mechanics, managed to forecast the event with remarkable precision, stating that the eclipse would be visible to within four minutes of the actual occurrence. Various locations, including parts of England and Scandinavia, experienced the stunning transition from daylight to darkness as the moon obscured the sun.
