The blue supergiant star, HDE 226868, is locked in an orbit with a black hole - Cygnus X-1. If you have a small telescope it is possible to see this interesting star. The black hole is not visible but its companion star is. This system is located in the constellation Cygnus, The Swan. The video explains where to look. It is possible to capture an image of this star with an SLR digital camera, Nikon, Canon and others produce cameras capable of long time exposures. The video also demonstrates using online telescopes to capture an image of this star.
The animations in this video were created with Starry Night software.

  • relaxing voice and... Fantastic video!

  • Black holes don't move, there a rip in space just like a wormhole.

  • Thank you for this! How cool is that, to be able to use a telescope from our computers and see these stars and constellations!

  • the more info on black hole was told by stephen hawking

  • spiral out.

  • This is very helpful. I always wondered where to point my scope to know I'm looking in the direction of a black hole. Thanks Scienceonline, but what about a neutron star???????????????????

  • When I have watched the stars I have always found Deneb->Sadr->DEL Cyg triangle kinda nice.. Dunno why, and the two stars between Deneb and DEL Cyg :)

  • I thought that it was very interesting that it was being followed by a damn black hole.

  • would it be possible with a large exposure to make a pic of the wobble of the compagnion-star?
