Over its 9-year mission, NASA’s Kepler Telescope turned its gaze to over half a million stars, revealing that 20-50% of all visible stars could harbor potentially habitable Earth-sized rocky planets. In our relentless search...
Black holes can destroy everything – but can they be destroyed? What happens if we push physics to the absolute limits, maybe even break it and the universe in the process? Let’s create a...
Imagine the vastness of the cosmos revealed in the 1970s, showing us that our galaxy is not just a stationary mass but is moving at an incredible speed of 390 miles per second. This...

MARSHA is our proposal for a Martian surface habitat. It’s born of a careful response to the Martian environment and a synergy between structural, architectural and construction principles with human experience at the center....
Right now, you’re looking at renderings of human settlements on Mars. These designs were part of NASA’s 3D Printed Habitat Challenge, a 4-year long competition aimed at engineering homes for another planet. The brightest...

This spacesuit, built in 1974, was reported to cost between $15 million and $22 million. Today, that would be about $150 million. Having not delivered any new mission-ready extravehicular suits since then, NASA is...
This is no ordinary rocket engine. Limited by the technology of their times engineers and physicists have theorized this propulsion method for centuries, but the constraints of time may have just lifted with NASA’s...
[MUSIC PLAYING] Artificial gravity, it’s an essential plot element in most science fiction stories. But do any of those stories actually get artificial gravity right? [MUSIC PLAYING] Whether you realize it or not, artificial...
