NGC 6240 Animations
Black Hole Merger Animation
Black Hole Merger Animation

  • The movie shows a merger of two galaxies (simulation) that forms a single galaxy with two centrally located supermassive black holes surrounded by disks of hot gas. The black holes orbit each other for hundreds of millions of years before they merge to form a single supermassive black hole that sends out intense gravitational waves.

    This sequence begins with a wide-field optical image of the galaxy NGC 6240 and then zooms into the central region where it dissolves to a Chandra X-ray image. The colors in the X-ray image show the intensity of the low (red), medium (green) and high (blue) energy X-rays. This image then dissolves to show only the highest-energy X-rays detected by Chandra, which come from gas around the two black holes in the center of the galaxy.

    • This sequence begins with a data simulation of two galaxies that are about to merge. The simulation then stops and fades into the highest-energy (5-8 keV) X-ray data of NGC 6240. These two distinct point sources in the Chandra data are proof to scientists that two black holes at the center of this galaxy.
