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).
The Black Hole is a 1979 American science fiction film directed by Gary Nelson and produced by Walt Disney Productions.The film stars Maximilian Schell, Robert Forster, Joseph Bottoms, Yvette Mimieux, Anthony Perkins and Ernest Borgnine, while the voices of the main robot characters are provided by Roddy McDowall and Slim Pickens (both uncredited).
Cygnus X-1 (Cyg X-1) Binary star system with orbit t=5.6 d 19 h 58 m 21.676 s [12] ... First black hole discovered: first observed in 1964 in X-rays, first speculated ...
A black hole, known as Cygnus X-1 (a real-life X-ray source believed to be an actual black hole), lies in the constellation Cygnus. An explorer aboard the spaceship Rocinante journeys toward the black hole, believing there may be something beyond it. As he moves closer, it becomes increasingly difficult to control the ship and he is eventually ...
The first black hole to be confirmed was Cygnus X-1, the brightest X-ray source in the Cygnus constellation. Since then, about 50 black holes have been discovered in systems where a normal star ...
The constellation is also home to Cygnus X-1, a distant X-ray binary containing a supergiant and unseen massive companion that was the first object widely held to be a black hole. Many star systems in Cygnus have known planets as a result of the Kepler Mission observing one patch of the sky, an area around Cygnus.
Of these, Cygnus A became the first radio galaxy, the other two being nebulae inside the Milky Way. [5] In 1953 Roger Jennison and M K Das Gupta showed it to be a double source. [6] Like all radio galaxies, it contains an active galactic nucleus. The supermassive black hole at the core has a mass of (2.5 ± 0.7) × 10 9 M ☉. [3]
The first strong candidate for a black hole, Cygnus X-1, was discovered in this way by Charles Thomas Bolton, [186] Louise Webster, and Paul Murdin [187] in 1972. [188] [189] Some doubt remained, due to the uncertainties that result from the companion star being much heavier than the candidate black hole. Currently, better candidates for black ...
