Do we really understand how black holes grow? Using new methods to run high resolution simulations, the authors of this paper investigate the evolution of gas near a supermassive black hole – and their results have serious implications for the models commonly used in cosmological simulations.
Black holes may seem large, but not compared to the scales we’ll talk about today.
Yes, ‘Oumuamua is weird; and no, it is probably not a probe sent by an alien civilization. Sometimes scientists (and journalists) should be a little more careful when making (and reporting on) extraordinary claims, especially when the word “alien” is involved.
The mere existence of a binary asteroid near Jupiter can enlighten us to conditions in the early Solar System and shake up what we thought we knew about this time period!
Understanding the physics of a certain emission line will allow astronomers to study galaxies that existed a long time ago far, far away.
Dead zones!?! Dust?! An arbitrary pumpkin metaphor!?
