Governments around the world focus on ensuring Humanity's by developing the means to colonize other planets. In the end, to spread resources, rather than sending... (more)	—	almost 7 years ago
Question	—	How would a neutron star affect the habitability of planets orbiting a companion star? A star system consisting of two stars forms, with one being more massive. As such, the larger star soon exhausts its fuel and ends up as a neutron star. The secondary star has a semi-major axis of 700 au, with the closest approach being 438 au. Based on the information, would the secondary star be a... (more)	—	almost 7 years ago

Question	—	Is this atmospheric composition breathable, and what would it look like? I have developed a fictional planet with the following atmospheric composition; 60.4% Nitrogen 27.6% Oxygen 9.8% Xenon 1.5% Water Vapor 0.64% Argon 0.06% Carbon Dioxide Is this breathable to humans with an atmospheric pressure similar to Earth's? What about 50%, 200%, and 500% of Earth's atmosphe... (more)	—	almost 7 years ago
