Bedtime Astronomy

The eROSITA space telescope has released its second major X-ray catalog, offering one of the most detailed views yet of the high-energy universe.

With nearly two million sources, including stars, supernova remnants, and supermassive black holes, the dataset is helping astronomers build three-dimensional maps of cosmic evolution and uncover new clues about the early universe.

What if future Mars habitats could be 3D-printed using materials grown and gathered on the planet itself?

Researchers have developed a bio-based construction material combining Martian regolith, gelatin, and genetically engineered yeast that could form structures as strong as concrete. Still tested only in simulated conditions, the technology could point toward a more sustainable and recyclable way to build future colonies on Mars.

After nearly a decade asleep in space, a crucial instrument aboard the BepiColombo mission has finally been switched on.

The BELA laser altimeter survived years of extreme conditions and is now ready to map Mercury’s surface in unprecedented detail. When BepiColombo reaches its science orbit in 2027,

BELA will help create the most precise 3D maps ever made of the Solar System’s innermost planet. But what can these new maps reveal about the mysterious world closest to the Sun?

Boötes Void, known as the “Great Nothing,” is a vast region of space roughly 330 million light-years across containing far fewer galaxies than expected.

Formed as smaller cosmic voids merged and matter was pushed toward their edges, it offers a rare glimpse into an almost empty universe. Studying this enormous void could reveal new clues about galaxy formation, dark energy, and the expansion of the cosmos.

Hubble and James Webb have revealed surprising clues about tiny icy worlds at the edge of the Solar System.

Studying objects as small as 5 kilometers across, astronomers found that these distant bodies preserve ancient colors and compositions while showing far fewer small objects than current models predict. The findings offer a rare glimpse into the original building blocks of the planets.
