Modeling reveals how dwarf planet Ceres powers unexpected geologic activity      (via sciencedaily.com)     Original source 

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.

Space travel: Bone aging in fast forward      (via sciencedaily.com) 

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.

Scientists discover places on the moon where it's always 'sweater weather'      (via sciencedaily.com) 

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.

Explosive volcanic eruption produced rare mineral on Mars      (via sciencedaily.com) 

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.

Why Jupiter doesn't have rings like Saturn      (via sciencedaily.com) 

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.

Global map of lunar hydrogen: Data confirms role water played in moon's formation      (via sciencedaily.com)     Original source 

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.

New model predicts how temperature affects life from quantum to classical scales      (via sciencedaily.com) 

A new theory explains how every process depends on temperature. This theory could help researchers make accurate predictions in a range of areas, including biological responses to climate change, the spread of infectious diseases, and food production.

Go with the flow: New findings about moving electricity could improve fusion devices      (via sciencedaily.com) 

Researchers have found that updating a mathematical model to include a physical property known as resistivity could lead to the improved design of doughnut-shaped fusion facilities known as tokamaks.

Deep dive into the dusty Milky Way      (via sciencedaily.com)     Original source 

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.

Predicting equatorial plasma bubbles with SWARM      (via sciencedaily.com) 

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 a Martian meteorite can teach us about Earth's origins      (via sciencedaily.com) 

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.

Space rocket junk could have deadly consequences unless governments act      (via sciencedaily.com)     Original source 

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.

Floating in space might be fun, but study shows it's hard on earthly bodies      (via sciencedaily.com) 

Bone loss happens in humans -- as we age, get injured, or any scenario where we can't move the body, we lose bone. Understanding what happens to astronauts and how they recover is incredibly rare. It lets us look at the processes happening in the body in such a short time frame. We would have to follow someone for decades on Earth to see the same amount of bone loss.

Laser creates a miniature magnetosphere      (via sciencedaily.com) 

A research team realized magnetic reconnection driven by electron dynamics in laser-produced plasmas and measured the pure electron outflows. Their findings will be applied not only to space and astrophysical plasmas, but also to magnetic propulsion and fusion plasmas.

Asteroids: Researchers simulate defense of Earth      (via sciencedaily.com) 

NASA's Double Asteroid Redirection Test (DART) mission is the world's first full-scale planetary defense test against potential asteroid impacts on Earth. Researchers now show that instead of leaving behind a relatively small crater, the impact of the DART spacecraft on its target could leave the asteroid near unrecognizable.

Climate damage caused by growing space tourism needs urgent mitigation      (via sciencedaily.com) 

A formidable space tourism industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study.
