The new image shows the galaxy NGC 1266, a transitional object with a clutch of young stars that likely collided with a smaller galaxy 500 million years ago

A new model explains how Ganymede got its molten core — which in turn has given Jupiter's largest moon its magnetic field.

The post How Jupiter’s Moon Ganymede Melted Its Core appeared first on Sky & Telescope.

No quantum gravity. The wrong peak in the wave function. Boltzmann Babies. Roger Penrose pointing out that the arrow of time was smuggled in through the back door. The no-boundary proposal is beautiful. It is also possibly wrong in many specific ways.
