Scientists at the Ural Federal University (UrFU) with colleagues from the Arabian Peninsula have improved the radiation protection properties of glass, in particular borate glasses (boron oxide-based glass). They introduced special additives into the basic composition of the glass - heavy metal oxides. This significantly increased the density of the material without affecting its transparency. A

Europa is a prime candidate for life in our solar system, and its deep saltwater ocean has captivated scientists for decades. But it's enclosed by an icy shell that could be miles to tens of miles thick, making sampling it a daunting prospect. Now, increasing evidence reveals the ice shell may be less of a barrier and more of a dynamic system - and site of potential habitability in its own right

Ridges that criss-cross the icy surface of Jupiter's moon Europa indicate there are shallow pockets of water beneath, boosting hopes in the search for extra-terrestrial life, scientists said Tuesday.
Europa has long been a candidate for finding life in our solar system due to its vast ocean, which is widely thought to contain liquid water - a key ingredient for life.

The NASA/ESA Hubble Space Telescope is celebrating its 32nd birthday with a stunning look at an unusual close-knit collection of five galaxies, called the Hickson Compact Group 40. This snapshot reflects a special moment in their lifetimes as they fall together before they merge.
This menagerie includes three spiral-shaped galaxies, an elliptical galaxy and a lenticular (lens-like) galaxy.

It's been 50 years since humans first walked on the moon. Since then, astronauts have primarily explored low Earth orbit. Now that NASA is preparing to return to the moon, experts are reevaluating the practicality of the spacesuit.
Ana Diaz Artiles, assistant professor in the Department of Aerospace Engineering at Texas A&M University, and graduate student Logan Kluis have been working on developments for the SmartSuit, a new spacesuit architecture that would create a safer and better spacesuit environment for Extravehicular Activity (EVA) on planetary surfaces.
The SmartSuit is a spacesuit architecture proposed by Diaz Artiles that focuses on three key improvements to the current suit design; increased mobility, enhanced safety and informed interaction between the environment and the astronaut. Most recently, Diaz Artiles and Kluis, in collaboration with Robert Shepherd, associate professor at Cornell University, have been developing prototypes of soft-robotics assistive actuators for the knee joints.
"The current spacesuit has been designed for microgravity conditions; in these conditions, astronauts don't need to walk or move around using their lower body, they typically translate themselves using their upper body," said Diaz Artiles.
