recently announced the discovery of the black hole, which sits about 1,600 light years from Earth. </span> <span data-start-time='37188' data-end-time='42833'>A light year is the distance light travels in one year. </span> <span data-start-time='42833' data-end-time='50833'>In space, light moves about 9.4 trillion kilometers each year.</span> <span data-start-time='50833'
