Stephen Hawking's final message
Famous cosmologist Stephen Hawking—who lived for half a century after being diagnosed with Lou Gehrig's disease—delivered a final speech just before he died in 2018. In the video, Hawking talks about the importance of science and reason in...
An introduction to nuclear thermal propulsion
Nuclear thermal propulsion: game changing technology for deep space exploration
How rockets work: a complete guide
Rockets of all kinds are still our only way of reaching space—but how exactly do they work?
The promise of nuclear propulsion
This rocket engine design, combined with a special fuel, could get humans from Earth to Mars in just three months.
A data visualization exploring six decades of spacewalks
Astronauts' initial small step for mankind may standout, but how many steps have we taken so far? Space and moonwalks further our understanding of spaceflight, celestial bodies, and space itself. Created to resemble a constellation map, this chart...
How many galaxies are there? (Hint: a lot)
The universe is considered by some to be infinite, while others find comfort in the fact that it may have an end. Click for more.

Watch the Arecibo Observatory collapse
Watch this remarkable footage of the Arecibo Observatory’s 900-ton platform falling into the 1,000-foot wide (305 meters) dish below, followed by footage from a drone coincidentally observing the cables at the time they snapped.
Where should we look for extraterrestrial life?
Not all planets are created equal. Those capable of sustaining life as we known it must meet strict criteria, the most important of which is being at the right distance from their host star to have liquid water on the surface.
