| New simulation shows how galaxies feed their supermassive black holes Posted: 17 Aug 2021 10:14 AM PDT While other simulations have modeled black hole growth, new model is the first single computer simulation powerful enough to comprehensively account for the numerous forces and factors that play into the evolution of supermassive black holes. Simulation shows that galaxies' spiral arms 'put the brakes on gas,' enabling it to fall into the black hole and as gas heats up while falling into a black hole, it turns into a bright quasar. |
| Fast changes between the solar seasons resolved by new sun clock Posted: 17 Aug 2021 10:14 AM PDT Violent activity on our Sun leads to some of the most extreme space weather events on Earth, impacting systems such as satellites, communications systems, power distribution and aviation. The roughly 11 year cycle of solar activity has three 'seasons', each of which affects the space weather felt at Earth differently: (i) solar maximum, the sun is active and disordered, when space weather is stormy and events are irregular (ii) the declining phase, when the sun and solar wind becomes ordered, and space weather is more moderate and (iii) solar minimum, when activity is quiet. Scientists found that the change from solar maximum to the declining phase is fast, happening within a few (27 day) solar rotations. |
