The United States already has a space agency: NASA. So why do we need a Space Force, and what would it do? Could a Space Force strain diplomatic relationships, reigniting the race to militarize space?
The upper atmosphere of Venus is the most Earth-like extra-terrestrial location in the solar system. It could even host life.
After the first moon landing, the feelings that propelled a unified national mission quickly dissipated. Could Armstrong have played a bigger role in galvanizing the public for future projects?
The new film is a down-to-Earth portrayal of astronaut Neil Armstrong and our complex relationship with the Moon.
It has been 10 years since Elon Musk's SpaceX launched the commercial space age. What hurdles must be overcome before private companies begin exploring, colonizing and mining other planets?
A 90-minute presentation in 1968 showed off the earliest desktop computer system. In the process it introduced the idea that technology could make individuals better – if government funded research.
Senegal has made great strides in astronomy and planetary sciences in recent years.
The career arc of Nichelle Nichols – the first black woman to have a continuing co-starring role on TV – shows how diverse casting can have as much of an impact off the screen as it does on it.
The Swift Observatory passed a milestone: 1 million snapshots of the universe. These exquisite and revealing pictures have captured the births and deaths of stars, gravitational waves and comets.
The moon is our closest neighbour and our best hope for building capacity to explore space.
The longest lunar eclipse this century, and other special features such as Mars looking spectacular will be seen.
Each meteorite is a piece of the puzzle to understanding our solar system.
About 5 percent of all UFO sightings cannot be easily explained by weather or human technology. A physicist argues that there's compelling evidence to justify serious scientific study and that the skeptics should step aside – for the sake of humanity.
An asteroid on a collision course with Earth is inevitable. Astronomer Michael Lund explains how a new telescope under construction in Chile will become a vital tool for detecting objects that could devastate our planet.
35 years ago Sally Ride became the first American woman in space. But rather than focus on her own extraordinary achievements, her passion became boosting the number of girls pursuing STEM. Another pioneering astronaut remembers her friend and colleague.
Australia occupies a unique location vital for supporting NASA and ESA deep-space missions.
Following NASA's latest discovery of organic matter on the red planet, new findings in a salt lake in California could point to where to look for alien life.
Astronomers are gathering an exponentially greater amount of data every day – so much that it will take years to uncover all the hidden signals buried in the archives.
Now's a great time to see Jupiter as it's about to be the closest to Earth for some time. Time too to catch up with the latest on the Juno mission, exploring the largest planet in our Solar System.
