Welcome back to our series on interstellar travel! In our first installment, we examined attempts to realize nuclear propulsion and how the technology could be used to reach the nearest star. In our second, we examined how ...
The mission to save NASA's sinking Swift Observatory was called off Wednesday, dooming the telescope to a fiery reentry later this year.
Eclipses may be wondrous, but nothing beats seeing the northern and southern lights from space.
The research team led by materials scientist Ralf Busch from Saarland University is preparing for its first science-in-space mission. If everything goes to plan, from 31 August the researchers will spend one week remotely ...
Remember the "Wow!" signal? That high-energy radio signature occurred in 1977, when Earth was much "quieter" in the radio band. If it happened today, it probably wouldn't even move the needle on the background noise of human ...
Some of Earth's microbes likely to hitch a ride to space with human explorers could survive in the shaded nooks and crannies of the moon's South Pole region, NASA scientists say.
Before people can mine resources on the moon, asteroids or Mars, they need to answer a few key questions: What is there? How much is there? And where can it be found? A team led by SETI Institute research scientist Pablo ...
As humanity gets closer to the possibility of long-term interplanetary travel, psychologists have started raising concerns about astronauts' mental health. Researchers at Texas A&M University conducted research on sailors ...
Astronomers have detected an enormous cloud of gas tens of millions of degrees hot surrounding one of the most extreme structures known in the early universe. The study offers one of the clearest views yet of a galaxy cluster ...
NASA has released a report recommending an initial health standard for the Martian dust that astronauts could inhale during future missions. Although sending people to Mars is still years away, NASA needs to establish safety ...
