This is a nice video published on John Michael Godier’s youtube channel, which talks also about our recent paper on the pulsar habitable zone and pulsar planets. Enjoy!

The Habitable Zone Around Neutron Stars

In the past 20 years, there has been an explosion of discoveries in the field of exoplanets, i.e. planets located outside our solar system. Today we know more than 3,600 exoplanets around 2,700 different stars and the number grows day… Continue Reading →

Detecting the Sound of Neutron Stars

If a sound propagates and bounces off an object, its wiggly echo brings signatures of the physical properties of that object . Bats, dolphins and other cetaceans are famous for using this principle, named echolocation, to chase prey and identify objects… Continue Reading →

The Super-Massive Black Hole Stays on a Diet

At the very center of our galaxy lives a gigantic black hole with a mass more than four million times that of the Sun. The existence of such an immense monster does not constitute an anomaly in our Universe but rather… Continue Reading →
