Researchers have developed a self-healing layer for all-solid-state lithium batteries, enhancing their safety, performance, and longevity. The innovation could power safer electric vehicles and sustainable grid storage while reducing manufacturing complexity.

Astronomers have captured the first image of two supermassive black holes orbiting in quasar OJ 287. The smaller black hole’s jet spirals due to gravitational forces from the larger one. This discovery validates dual-core theories and opens doors for research on gravitational waves and galaxy evolution.

A new study in Acta Astronautica warns that Low Earth Orbit is becoming dangerously congested. Since 2019, the number of satellites performing more than ten collision-avoidance maneuvers per month has risen sevenfold. With nearly 25,000 tracked objects and more launches planned, scientists fear a chain-reaction risk and call for stronger global coordination in orbital management.

Astronomers using a global radio telescope array have detected the smallest known pure dark matter clump, roughly a million times the Sun’s mass. Found through a faint gravitational distortion in an Einstein ring, it offers new insight into how dark matter halos form across the universe.
