Besides he constructed the very first reflecting telescope and independent of Gottfried Wilhelm Leibniz developed differential and integral calculus [10]. “We are to admit no more causes…
Hipparchus of Nicaea and the Precession of the Equinoxes

Hipparchus of Nicaea and the Precession of the Equinoxes

Hipparchus of Nicaea was a Greek astronomer, geographer, and mathematician in the second century BC. He is considered the founder of trigonometry but is most famous for his incidental discovery of precession of the equinoxes. His other reputed achievements include the discovery and measurement of Earth‘s precession, the compilation of the first comprehensive star catalog of the western world, and possibly the invention of the astrolabe, also of the armillary…
Johannes Fabricius and the Sunspots

Johannes Fabricius and the Sunspots

Probably on June 13, 1611, Dutch astronomer Johannes Fabricius published his Narratio de maculis in sole observatis et apparente earum cum sole conversione (Account of Spots Observed on the Sun and of Their Apparent Rotation with the Sun), which counts as the first published description of sunspots. Nevertheless, sunspots have been discovered earlier, as the first record of a sunspot drawing dates back into the 12th century to John of…
SN 1987A – Supernova

SN 1987A – Supernova

On February 24, 1987, SN 1987A, a supernova in the outskirts of the Tarantula Nebula in the Large Magellanic Cloud occured visible to the naked eye. It was the closest observed supernova since Kepler’s Supernova  SN 1604, which occurred in the Milky Way itself. Due to the relative proximity to Earth, SN 1987A became one of the best studied supernovae of all time. After its discovery was announced, nearly every…

Giuseppe Piazzi and the Dwarf Planet Ceres

The Asteroid Ceres image by Hubble space telescope On January 1, 1801, Italian Catholic priest of the Theatine order, mathematician, and astronomer Giuseppe Piazzi discovered Ceres, today known as the largest member of the asteroid belt.

As you might know, our Solar System does not only comprise the Sun and the planets Mercury,…

Much More Powerful Than Expected – Kepler’s Supernova

X-ray, Optical and Infrared Composite of Kepler’s Supernova Remnant On October 17, 1604, the famous German astronomer Johannes Kepler started his observations of the 1604 supernova, named after him as Kepler’s Supernova or Kepler’s Star. Special about this ‘new’ star was it being the very last observed supernova in our own galaxy, the milkyway. The supernova was first observed on October 9, 1604, a few days before Kepler really looked…
And Kepler Has His Own Opera – Kepler’s 3rd Planetary Law

And Kepler Has His Own Opera – Kepler’s 3rd Planetary Law

Kepler’s Model of the Solar System from Mysterium Cosmographicum (1600) On May 15, 1618, famous astronomer Johannes Kepler discovered the 3rd and also last of his planetary laws, and concluded the general revolution of our celestial world that started with Nikolaus Kopernikus about 100 years earlier. And that made him rather popular as he still is today. Did you know that there is a Kepler crater on the Moon, a Kepler…
