NASA continues to progress with the development of the Nancy Grace Roman Space Telescope (RST), the next-generation observatory with a target launch date of 2027. As the direct successor to the venerable Continue reading

One of the basic principles of cosmology is the Cosmological Principle. It states that, no matter where you go in the Universe, it will always be broadly the same. Given that we have only explored our own Solar System there is currently no empirical way to measure this. A new

We all know that asteroids are out there, that some of them come dangerously close to Earth, and that they've struck Earth before with catastrophic consequences. The recent discovery of asteroid 2024 YR4

It’s a familiar sight to see astronauts on board ISS on exercise equipment to minimise muscle and bone loss from weightlessness. A new study suggests that jumping workouts could help astronauts prevent cartilage damage during long missions to the Moon and Mars. They found that

White dwarfs are the remnants of once brilliant main sequence stars like our Sun. They're extremely dense and no longer perform any fusion. The light they radiate is from remnant heat only.

Astronomers have doubted that white dwarfs could host habitable planets,

Venus is very variable. Its surface constantly changes from volcanic activity, and the difference between its lower and upper atmosphere is night and day, with a dramatic change in sulfuric acid concentration. So, designing a system that works for all parts of Venus is

Hypervelocity stars have been seen before but NASA scientists have just identified a potential record-breaking exoplanet system. They found a hypervelocity star that has a super-Neptune exoplanet in orbit around it. This discovery could reshape our understanding of planetary

MSL Curiosity is primarily a rockhound. It's at Gale Crater, examining the rocks there and on Mt. Sharp, which sits in the middle of the crater and rises 5.5 km above the crater floor. But Curiosity is also a skywatcher, and its primary camera, Continue reading

Finding alien life may have just got easier! If life does exist on other worlds in our Solar System then it’s likely to be tiny, primative bacteria. It’s not so easy to send microscopes to other worlds but chemistry may have just come to the rescue. Scientists have developed a

Hydrogel protection could be crucial for safe human space exploration.

It’s a key problem that will need to be addressed, if humans are to attempt deep-space, long duration missions. Not only is radiation exposure a dangerous health risk to humans, but it also
