Meet the autonomous Moon robots about to change space travel forever
If we want to explore the Solar System even further, we'll need self-sufficient robots to help us do it. And that’s why scientists are putting futuristic bots through their paces on the lunar-like landscape of Mount Etna.
What would actually happen if we discovered a message from an alien planet?
The SETI mission is scouring the skies for signs of extraterrestrial life. So what will the researchers do when they receive a signal, and will they send a message back?
We pick up a signal from ET. What do we do next?
When an alien message is detected, these are the exact procedures that need to be followed.
Inside the UK’s Silicon Valley for nuclear fusion, where unlimited energy is becoming a reality
For decades, the technology to develop clean, safe fusion power has remained tantalisingly out of reach. Now, though, a new breed of start-ups could have cracked it at last. Will we finally be able to wave goodbye to fossil fuels?
NASA's Lunar Gateway: The plans for a permanent space station that will orbit the Moon
2022 will see NASA, with help from its international partners, take the first major step on humanity’s journey back to the Moon, and the start of a mission to establish an outpost alongside Earth’s natural satellite.
