Johann Baptist Cysat (1588–1657) was a pioneering Swiss Jesuit astronomer, mathematician, and architect. He is celebrated for his early telescopic observations, specifically recognizing the nebulous nature of the Orion Nebula and being the first to observe and describe a comet through a telescope.
Major Contributions and Achievements
Telescopic Comet Observations: Cysat is credited with making the first telescopic observations of a comet during the great comet of 1618. He tracked it continuously for two months, concluding that its tail pointed away from the sun.
Orion Nebula Discovery: While utilizing a telescope in 1611, Cysat independently discovered the Orion Nebula (M42), noting its glowing "nebulosity".
Sunspot Research: He collaborated with his mentor, Christoph Scheiner, to independently observe and track sunspots in 1611, a discovery famously contested by Galileo.
Planetary Transits: Cysat was one of only a handful of European astronomers to successfully observe the transit of Mercury across the Sun in November 1631.
Life and Career
Early Life: Born in Lucerne, Switzerland, Cysat joined the Society of Jesus and studied under Christoph Scheiner at the University of Ingolstadt in Germany, eventually succeeding him as a professor of mathematics.
Architectural Works: Beyond astronomy, Cysat was a skilled architect. In the 1630s, he designed the Jesuit church in Innsbruck, Austria.
Leadership Roles: He served as Rector of the Jesuit College in Lucerne and held leadership roles at Jesuit colleges in Innsbruck and Eichstätt, before returning to Lucerne where he passed away in 1657.

Johann Baptist Cysat (Cysatus latino) nasceu em Lucerna, Suíça em 1588 ou 1586. Tornou-se astrônomo jesuíta e estudante de Christoph Scheiner (1575-1650) em Ingolstadt, Alemanha. Em 1611, com um telescópio, Scheiner e Cysatus começaram a observar manchas solares, que descobriram independentemente dos outros (em particular Galileu), estimulado por uma publicação de Kepler. Em 1616 ou 1618, Cysatus sucedeu Scheiner como professor de matemática e a astronomia. De 1623-7, foi Reitor do Colégio Jesuíta em Lucerna. 1627-8 foi enviado para a Espanha, e na década de 1630, arquiteto do jesuíta igreja em Innsbruck. 1637-41 ele presidiu o Colégio Jesuíta em Innsbruck, 1646-50 o Colégio Jesuíta em Eichstätt. Posteriormente retornou a Lucerna onde morreu em 1657.
Cysatus foi homenageado ao nomear uma Cratera Lunar em sua homenagem (66.2S, 6,1W, 48.0 km diâmetro, em 1935).
Cysatus descobriu de forma independente o Nebulosa de Órion
M42 em 1611, um ano após sua descoberta original por PeirescPeiresc. Publicou essas observações em 1619, em sua Mathematica astronomica de cometa anni 1618 (Cysatus 1619) (em inglês). No entanto, esta publicação e descoberta caiu esquecida até que redescoberta por R. Wolf (1854); também ver G... Bigourdan (1916).
Outras observações incluem o trânsito de Mercúrio de 7 de setembro de 1631.

He later returned to Lucerne where he died in 1657.
Cysatus was honored by naming a Lunar Crater after him (66.2S, 6.1W, 48.0 km diameter, in 1935).
Cysatus independently discovered the Orion Nebula M42 in 1611, one year after its original discovery by Peiresc. He published these observations in 1619, in his Mathematica astronomica de cometa anni 1618 (Cysatus 1619). Nevertheless, this publication and discovery fell forgotten until their rediscovery by R. Wolf (1854); also see G. Bigourdan (1916).
Other observations include the Mercury transit of September 7, 1631.
