The Pulsar Habitable Zone

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! Share on FacebookTweetFollow usSave

Fermi Paradox and Superintelligence 2: The Small Colonies Hypothesis

Let’s resume our discussion on the implications of the Fermi paradox on superintelligence. As I said in my previous article, any civilization that masters space travel and achieves the possibility of building megastructures, must have developed superintelligence as a prerequisite….

Fermi Paradox and Super-intelligence

The Fermi paradox is the known contradiction between the lack of observational evidence for advanced alien civilizations and the estimates of the number of such civilizations in the Universe. The latest results of the Kepler space observatory suggest that about… Continue Reading →

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 →

Life in the Solar System and Beyond

One of the most difficult problems that science still needs to solve is the question of the origin of life. We have very strong evidence that life emerged on Earth around 3.7 billion years ago when our planet was less… Continue Reading →

Welcome to Pluto

After a long journey of 9 years in the solar system, the New Horizons spacecraft has conducted the first in-situ reconnaissance of Pluto. Our solar system is made by rocky planets like the Earth, Mars, Venus and Mercury that populate its inner regions,… Continue Reading →

Lightweight and Supermassive Black Holes Hidden in Galaxies

In the past few days, there has been two interesting astrophysics news about black holes. The first one is about a super-massive black hole discovered in an ultra-compact dwarf galaxy. Such galaxies are tiny (both in mass and size) when… 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 →
