Researchers at the University of Illinois have pulled off a laser first: they built a new kind of eye-safe laser that works at room temperature, using a buried layer of glass-like material instead of the usual air holes. This design not only boosts laser performance but also opens the door to safer and more precise …

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive “orphan” galaxies have likely been stripped of their dark matter by the Milky Way’s gravity and hidden from view. If spotted by next-gen telescopes like the Rubin Observatory’s LSST, …

100 ghost galaxies may be orbiting the Milky Way—and we’re just now uncovering them Read More »

Imagine a star powered not by nuclear fusion, but by one of the universe’s greatest mysteries—dark matter. Scientists have proposed the existence of “dark dwarfs,” strange glowing objects potentially lurking at the center of our galaxy. These stars might form when brown dwarfs absorb enough dark matter to prevent cooling, transforming into long-lasting beacons of …

A 2.35-billion-year-old Moon rock that fell to Earth in Africa is rewriting what we know about lunar volcanism. This rare meteorite, studied by UK scientists and unveiled at a major geochemistry conference, reveals that the Moon was volcanically active far longer than previously thought. With a unique chemical makeup and an age that bridges a …
