Black hole spurts jets of iron and nickel

Jets shooting from a small black hole pack extra power.

New observations show that the jets of black hole 4U 1630-47, in the direction of the constellation Norma, carry massive particles, such as iron and nickel atoms, instead of the typical low-mass particles such as electrons. The fast-moving, heavy-particle jets, which move at two-thirds the speed of light,  have more power than spurts of only low-mass particles, astronomers report November 14 in Nature.

Though 4U 1630-47 is only three to 10...
