Last year, astronomers discovered a quiescent black hole in a distant galaxy that erupted after shredding and consuming a passing star. Now researchers have identified a distinctive X-ray signal observed in the days following the outburst that comes from matter on the verge of falling into the black hole.
Studies of one of the galaxy’s most active black-hole binaries reveal a dramatic change that will help scientists better understand how these systems expel fast-moving particle jets.
NASA scientists and their international partners using the new Japanese Suzaku satellite have collected a startling new set of black hole observations, revealing details of twisted space and warped time never before seen with such precision. The observations include clocking the speed of a black hole’s spin rate and measuring the angle at which matter… Continue reading »
