The technology of an advanced alien civilization is likely to produce many signs that could be detected across the vastness of space. Two astronomers explain the search for technosignatures.
The Double Asteroid Redirection Test successfully showed that it is possible to crash a spacecraft into a small asteroid and change its orbit. This technique could save Earth from asteroids in the future.
Scientists have uncovered the long-term history of our receding moon. And it’s not from studying the moon itself, but from reading signals in ancient layers of rock on Earth.
As the potential for space travel increases, it is necessary to develop methods to protect astronauts from environmental stresses in space. Studying the DNA of baker’s yeast may provide some clues.
The Double Asteroid Redirection Test successfully showed that it is possible to crash a spacecraft into a small asteroid. Whether the approach could save Earth from a future threat remains to be seen.
Crashing the 1,340-pound DART probe into the small moonlet orbiting the asteroid Didymos should redirect its trajectory – and could be a model for how to save Earth in the future.
Newly discovered super-Earths add to the list of planets around other stars that offer the best chance of finding life. An astronomer explains what makes these super-Earths such excellent candidates.
When the Orion Crew Capsule orbits the Moon there will be no one on board. But the mission will mark a key step in bringing humans back to Earth’s dusty sidekick.
The era of lunar resource use is quickly approaching. But with legal and practical issues still looming, nations are starting to think about sustainable ways to mine and protect the Moon.
An astrophysicist explains what wormholes are and how these theoretical space-time tunnels have popped up in the solutions to a set of decadesold equations.
A new publication clarifies how existing legal frameworks apply to space exploration and development. The McGill Manual also highlights the catastrophic implications of conflict in space.
Private satellite companies have boomed in recent years, and many experts have wondered what role they would play in a conflict. They have proved to be invaluable to Ukraine in recent months.
The head of the Russian space agency announced that the country will withdraw from the International Space Station after 2024. A space policy expert explains what this means and why it’s happening now.
