Officially designated 1P/Halley, it is also commonly called Comet Halley, or sometimes simply Halley. Halley's periodic returns to the inner Solar System have been observed and recorded by astronomers around the world since at least 240 BC, but it was not until 1705 that the English astronomer Edmond Halley understood that these appearances ...
It was known as Halley's Eclipse, after Edmond Halley (1656–1742) who predicted this eclipse to within 4 minutes accuracy. Halley observed the eclipse from London where the city of London enjoyed 3 minutes 33 seconds of totality. He also drew a predictive map showing the path of totality across the Kingdom of Great Britain.
Omega Centauri (ω Cen, NGC 5139, or Caldwell 80) is a globular cluster in the constellation of Centaurus that was first identified as a non-stellar object by Edmond Halley in 1677. Located at a distance of 17,090 light-years (5,240 parsecs ), it is the largest known globular cluster in the Milky Way at a diameter of roughly 150 light-years. [ 10 ]
Around 1677, Edmond Halley observed a transit of Mercury across the Sun, leading him to realise that observations of the solar parallax of a planet (more ideally using the transit of Venus) could be used to trigonometrically determine the distances between Earth, Venus, and the Sun. [16] In 1705, Halley realised that repeated sightings of a ...
Messier 13 was discovered by Edmond Halley in 1714, [2] and cataloged by Charles Messier on June 1, 1764, [9] into his list of objects not to mistake for comets; Messier's list, including Messier 13, eventually became known as the Messier catalog. [10] It is located at right ascension 16 h 41.7 m, declination +36° 28'. Messier 13 is often ...
