If humanity intends to live and work beyond Earth, we need solutions for living sustainably in inhospitable environments. Even Mars, the most hospitable planet in the Solar System beyond Earth, is hostile to life as we know it. These include extreme temperature variations, a thin, unbreathable atmosphere, toxic soil, and higher-than-normal levels of solar and cosmic radiation. Given the distance between Earth and Mars and the time it takes to send missions there (6 to 9 months using conventional propulsion), these habitats must be closed-loop, self-sustaining environments that provide crews with food, water, and breathable air.

Dark matter is one of Nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it's real because its mass prevents galaxies from falling apart. But we don't know what it is.

The Hubble Space Telescope is one of the most successful scientific endeavours in history, maybe the most successful. It's been observing the heavens for more than 35 years since its launch in 1990. The JWST is the most powerful and complex space telescope ever built, and has been expanding our horizons since its launch in December, 2021. When working together, they create synergy that not only benefits science, but provides stunning images of the cosmos.

We all know what it's like when Earth is on the receiving end of a solar flare. Things get spicy in the upper atmosphere, and the outbursts have the potential to disrupt technology here at home. Catastrophic flares of radiation devastate planets around other stars, too. Now it looks like scientists have found that planets orbiting close to their stars can trigger the flares that threaten to harm them.

The James Webb Space Telescope (JWST) can tell us a lot about the subjects of its observations if it spends enough time with them. That includes lonely rocks on the edges of our solar system, such as the Trans-Neptunian Object (TNO) Quaoar. Recent observations using the NIRCam on JWST and pre-published on arXiv by researchers at the University of Central Florida, the Space Telescope Science Institute, and Kyoto University add a plethora of new data to our understanding of this enigmatic object, including insights into what might be causing its ring system and its hydrocarbon atmosphere.

Sometimes there are profound questions in life that must be answered, like “What is the meaning of existence?”, “Are we alone in the universe?” or “What happens if you throw a paper airplane from the International Space Station?” Luckily, that third one has finally been answered, because of course someone would eventually. A new paper from Maximilien Berthet and Kojiro Suzuki from the University of Tokyo looks at “the dynamics of an origami space plane during Earth atmospheric reentry” - in other words, what happens when you throw a paper plane out of the ISS.
