NASA's IXPE Measures White Dwarf Star for First Time
For the first time, scientists have used NASA's IXPE (Imaging X-ray Polarization Explorer) to study a white dwarf star. Using IXPE's unique X-ray polarization capability, astronomers examined a star called the intermediate polar EX Hydrae, unlocking the geometry of energetic binary systems.
In 2024, IXPE spent nearly one week focused on EX Hydrae, a white dwarf star system located in the c Star like early galaxies challenge views of cosmic evolution
Scientists at the University of Missouri have identified a small group of unusual objects in the early universe that look like stars in images yet behave like compact galaxies when analyzed in detail. Using NASAs James Webb Space Telescope JWST, Haojing Yan and colleagues at Mizzous College of Arts and Science found that these sources appear as single points of light while carrying the spectral We have no idea what most of the universe is made of, but scientists are closer than ever to finding out
When it comes to understanding the universe, what we know is only a sliver of the whole picture. Dark matter and dark energy make up about 95% of the universe, leaving only 5% "ordinary matter," or what we can see.

The extent and speed of ice moving off the ice sheets of Greenland and Antarctica into the sea – an important dynamic for climate and sea-rise modelling – has been captured over a 10-year period by satellites from the Copernicus Sentinel-1 mission.

Martian winds can have quite an impact. ESA’s Mars Express has spotted them whipping up sand grains and acting as a cosmic sandblaster, carving out intriguing grooves near Mars’s equator.
What Makes Air Refrigeration Safer for Food Storage
Food businesses rely on cold rooms and process chillers to keep products safe from farm to fork. When cooling systems fail or behave unpredictably, the result can be spoilage, recalls, or subtle quality drift that emerges only when products reach consumers. How College Students Really Afford Rent And Groceries Now
Many college students say that rent and basic food costs feel harder to manage than any other part of school. It's not unusual for students to work, budget, and still feel short at the end of the month. This leaves a lot of them unsure of how to cover the gap without taking on too much stress.

Media representatives joined French ESA astronaut Sophie Adenot, on Monday 5 January, for a hybrid press conference to learn more about her first mission to space.
This event, held at the European Astronaut Centre (EAC) in Germany, was the final media event in Europe ahead of her launch to the International Space Station.
Sophie selected the name ‘εpsilon’ for her first mission, currently planned no earlier than 15 February, reflecting the power of small, yet impactful contributions, and how many parts come together to make a whole.
During εpsilon, Sophie will conduct a wide range of tasks on the International
Chinese astronauts hone extreme cave survival skills
Twenty-eight astronauts and trainees have completed China's first cave-survival training program, a nearly monthlong exercise run by the Astronaut Center of China in Chongqing's Wulong district.
The course included more than 10 core activities such as environmental monitoring, cave mapping, simulated communication with ground control, and a series of psychological and behavioral drills in
