Cygnus X-1 (abbreviated Cyg X-1) [11] is a galactic X-ray source in the constellation Cygnus and was the first such source widely accepted to be a black hole. [12] [13] It was discovered in 1964 during a rocket flight and is one of the strongest X-ray sources detectable from Earth, producing a peak X-ray flux density of 2.3 × 10 −23 W/(m 2 ⋅Hz) (2.3 × 10 3 jansky).

Sh 2-101, at least in the field seen from Earth, is in close proximity to microquasar Cygnus X-1, site of one of the first suspected black holes. Cygnus X-1 is located about 15 ′ west of Sh 2-101. The companion star of Cygnus X-1 is a spectral class O9.7 Iab supergiant with a mass of 21 solar masses and 20 times the radius of the Sun.
He identified the first clear candidate for a black hole, Cygnus X-1, with his colleague Louise Webster. He studied Mathematics and Physics at the universities of Oxford and Rochester . In 1962, he took an eight-week summer residential course supporting researchers at the Royal Greenwich Observatory in Herstmonceux and at the end was offered a ...

V404 Cygni is a microquasar and a triple star system in the constellation of Cygnus.It contains a black hole with a mass of about 9 M ☉ and an early K giant star companion with a mass slightly smaller than the Sun, and an evolved tertiary component.
Cygnus X was a trance music project from Germany named after the famous X-ray binary star Cygnus X-1. It began as a collaboration between Matthias Hoffmann and Ralf Hildenbeutel, who later left. [1] Other projects of the pair include A.C. Boutsen, Brainchild and Dee.FX. Their sound extends from hard to ambient trance.
