Space colonies would need closed-loop food systems, controlled farming, and recycling to survive. Here’s how off-world food production could actually work.
I. What is Chemical Enrichment of the Universe? Chemical enrichment of the universe refers to the process by which the abundance of chemical elements in the cosmos increases over time. This phenomenon is crucial for the formation of stars, planets, and ultimately, life. The universe began with primarily hydrogen and helium, the two lightest elements, … Read more
Mars is cold because of its thin atmosphere, greater distance from the Sun, and weak greenhouse effect.
I. What is a Protostar? A protostar is a young star that is still in the process of forming. It is the earliest stage in the life cycle of a star, before it begins nuclear fusion in its core and starts shining brightly. Protostars are typically surrounded by a dense cloud of gas and dust, … Read more
Space colonization could expand human civilization, but it also brings serious technical, biological, economic, and ethical risks worth understanding.
Learn what a Moon colony is, how it could function, and why agencies and private companies are planning lunar settlements.
Explore the essential systems, supplies, and technologies humans would need to live and work on Mars safely.
Moon dust is more than a nuisance: its sharp, clingy particles threaten astronauts, hardware, and future lunar bases.
Mars is hostile to humans for reasons that go far beyond cold weather, from radiation and thin air to toxic dust and scarce water.
What is a Substellar Object? A substellar object is a celestial body that is not massive enough to sustain nuclear fusion in its core, like a star, but is also not small enough to be considered a planet. These objects fall in the intermediate range between planets and stars, and they can include brown dwarfs, … Read more
