The compositions of meteorites show that volatile compounds of carbon, nitrogen, oxygen and hydrogen should be abundant in rocky planets, and could be released during and after accretion of the planets themselves to give primitive atmospheres and oceans. The earliest atmospheres would have contained ...
Transforming Mars into a life-friendly world doesn't have to be a herculean planet-wide effort. Humanity could make patches of the Red Planet habitable relatively cheaply and efficiently by placing thin layers of silica aerogel on or above the Martian surface, a new study suggests. The insulatin...
Human beings are a particular subset of life that require particular conditions. And it turns out oxygen in particular is very hard to make on Mars. That is, I think, beyond our technological horizons - it's a long time in the future. But warming Mars up, and restoring its thick carbon...
Astrobiologists seek to understand (among other things) how life arose and evolved on Earth, what governs the way life is organized and what makes a planet habitable. Astrobiology combines the disciplines of biology, chemistry, physics, geology and astronomy. Often, astrobiologists must use the ...

In The Privileged Planet, we argue that it isn’t. The conditions that make a planet habitable also make its inhabitants more likely to see solar eclipses. Q#2: Is our existence related to the transparency of the atmosphere? A: Atmospheres come in many forms, but not all allow for ...

Survival on a remote and deserted planet is just the beginning ofThe Planet Crafter, as your ultimate goal is terraforming the planet into a habitable place for humans to live. But before you transform an entire planet into another Earth, you first have to establish a base of operations, sep...
To make the Moon habitable, we would need to live in shelters. In addition to protecting us from meteorites, radiation and toxic lunar dust, a sealed shelter would allow us to breathe. Breathable air Taking a breath on the Moon would be deadly. The Moon technically does have an atmosphere...
