A mathematical model developed by space medicine experts could be used to predict whether an astronaut can safely travel to Mars and fulfill their mission duties upon stepping foot on the Red Planet.

At a time when astronomers around the world are reveling in new views of the distant cosmos, an experiment on the International Space Station has given researchers fresh insight into something a little closer to home: water.

Researchers have devised a plasma-based way to produce and separate oxygen within the Martian environment. It's a complementary approach to NASA's Mars Oxygen In-Situ Resource Utilization Experiment and may deliver high rates of molecule production per kilogram of instrumentation sent to space. The team presents the method for harnessing and processing local resources to generate products on Mars.

The star Betelgeuse appears as a brilliant, ruby-red, twinkling spot of light in the upper right shoulder of the winter constellation Orion the Hunter. But when viewed close up, astronomers know it as a seething monster with a 400-day-long heartbeat of regular pulsations. This aging star is classified as a supergiant because it has swelled up to an astonishing diameter of approximately 1 billion miles. If placed at the center of our solar system it would reach out to the orbit of Jupiter. The star's ultimate fate is to explode as a supernova.

Researchers discover the first definitive proof that the Moon inherited indigenous noble gases from the Earth's mantle. The discovery represents a significant piece of the puzzle towards understanding how the Moon and, potentially, the Earth and other celestial bodies were formed.

Researchers are exploring ways to use clay-like topsoil materials from the moon or Mars as the basis for extraterrestrial cement that could be used by astronauts to create building materials for life in outer space. Scientists have converted simulated lunar and Martian soils into geopolymer cement, which is considered a good substitute for conventional cement.

Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study planet formation have made the first-ever detection of gas in a circumplanetary disk. What's more, the detection also suggests the presence of a very young exoplanet.

Researchers have proven that when bodies exist in curved spaces, they can in fact move without pushing against something.

Students have completed a comprehensive brightness study to characterize mega-constellation satellites cluttering the skies.

NASA's James Webb Space Telescope has peered into the chaos of the Cartwheel Galaxy, revealing new details about star formation and the galaxy's central black hole.

For a long time, our view of Ceres was fuzzy, according to a geoscientist. A dwarf planet and the largest body found in the asteroid belt -- the region between Jupiter and Mars speckled with hundreds of thousands of asteroids -- Ceres had no distinguishable surface features in existing telescopic observations from Earth.

Long periods in space damage bone structure irreparably in some cases and can make parts of the human skeleton age prematurely by up to 10 years, according to new research. Adapted training programs in conjunction with medication could provide better protection for astronauts on future space missions. The research findings also have implications for treating rheumatic conditions in clinical practice.

A team led by planetary scientists has discovered shady locations within pits on the moon that always hover around a comfortable 63 degrees Fahrenheit. The pits, and caves to which they may lead, would make safer, more thermally stable base camps for lunar exploration and long-term habitation than the rest of the moon's surface, which heats up to 260 degrees during the day and drops to 280 degrees below zero at night.

Planetary scientists have an answer to a mystery that's puzzled the Mars research community since NASA's Curiosity rover discovered a mineral called tridymite in Gale Crater in 2016.

Because it's bigger, Jupiter ought to have larger, more spectacular rings than Saturn has. But new research shows Jupiter's massive moons prevent that vision from lighting up the night sky.

Using data collected over two decades ago, scientists have compiled the first complete map of hydrogen abundances on the Moon's surface. The map identifies two types of lunar materials containing enhanced hydrogen and corroborates previous ideas about lunar hydrogen and water, including findings that water likely played a role in the Moon's original magma-ocean formation and solidification.

An animated dive into the dusty Milky Way reveals the outlines of our galaxy taking shape as we look out further and further from Earth. Based on new data from an interactive tool that exploits data from the European Space Agency's Gaia mission and other space science data sets, astronomers have created an animation to model dust in the Milky Way.

Changes in atmospheric density after sunset can cause hot pockets of gas called 'plasma bubbles' to form over the Earth's equator, resulting in communication disruptions between satellites and the Earth. New AI models are now helping scientists to predict plasma bubble events and create a forecast.

What do Mars and Iceland have in common? These days, not so much. But more than 4.5 billion years ago, it's possible the Red Planet had a crust comparable to Iceland today. This discovery, hidden in the oldest martian fragments found on Earth, could provide information about our planet that was lost over billions of years of geological movement and could help explain why the Earth developed into a planet that sustains a broad diversity of life and Mars did not.

The re-entry of abandoned stages of rockets left in orbit from space launches have a six to 10 per cent chance of severely injuring or killing a human being in the next decade, according to a new study. Researchers say governments need to take collective action and mandate that rocket stages are guided safely back to Earth after their use, which could increase the cost of a launch, but potentially save lives.
