130 million light-years away, at the center of the galaxy NGC 3147,lurks a particularly bizarre supermassive black hole.The black hole, recently discovered by astronomers using the HubbleSpace Telescope, has a much larger disk of material orbiting around itthan scientists expected given how sparse the galaxy is, according to aEuropean Space Agency press release. Because the disk orbits so closelyto the black hole and the rest of the galaxy is so dim, the astronomersbelieve they directly observed Einstein’s theories of general andspecial relativity in action.The disk, which spins at one-tenth the speed of light, orbits so closelyto the supermassive black hole that its gravity alters how light travelsaway from it. As the light struggles to escape, its wavelength getsstretched out, making the disk appear redder.“This is an intriguing peek at a disc very close to a black hole, soclose that the velocities and the intensity of the gravitational pullare affecting how we see the photons of light,ö Università degli StudiRoma Tre astronomer Stefano Bianchi said in the press release.
