The ghosts of dead stars
Supernova remnants are some of the most visually impressive objects in space. Astronomer Kovi Rose offers us a unique window into these violent and powerful celestial events.
Something explosive always seems to be happening in space. We often see headlines in the news about dramatic events like a flaring star, a gravitational wave from colliding neutron stars, or the latest supernova erupting in a galaxy far, far away.
The stories normally tend to focus on the peak periods of these energetic events, which generate in a week roughly a trillion-trillion times as much energy as we generated on Earth last year. But what remains after a star’s collapse – a supernova remnant, as astronomers call it – is both spectacular and scientifically interesting.
