Saturn’s ocean moon Enceladus could support life – my research team is working on a way to detect alien cells there

Saturn has 146 confirmed moons – more than any other planet in the solar system – but one called Enceladus stands out. It seems to have the ingredients for life. From 2004 to 2017, Cassini – a joint mission of NASA, the European Space Agency and the Italian Space Agency – examined Saturn, its rings … Read more

The sky of this hellish exoplanet rains iron, creating a rainbow-like effect

There are many words that can be used to describe WASP-76b: hellish, torrid, turbulent, chaotic and even violent. This is an extrasolar planet that is so close to its star that it gets hot enough to vaporize lead. So, as you can imagine, “glorious” wasn’t one of those words until now. This more positive description … Read more

SpaceX Crew-7 astronauts share the good and bad of spending six months in space

Andreas Mogensen was impressed with how smooth the landing was. The first European Space Agency (ESA) astronaut (and the first non-American) to serve as a pilot on a US commercial spacecraft, Mogensen and his SpaceX Crew-7 crewmates returned to Earth after a 197-day stay on board from the International Space Station (ISS) on March 12. … Read more

A widespread solar storm affected spacecraft near the Sun, Earth and even Mars

A bright mass erupts from a red circle. Space weather may seem like a story from a galaxy far, far away, but when solar storms hit us on Earth, we are directly affected. These storms are the cause of the northern Lights, for example. They can even lead to temporary disruptions in our communications systems … Read more
