A new study suggests “black hole morsels” — tiny, asteroid-sized black holes from cosmic mergers — could emit detectable bursts of Hawking radiation. Observatories like HESS, HAWC, and Fermi may already hold clues. Detecting them could unlock insights into quantum gravity, unknown particles, and even hidden dimensions beyond the Standard Model.

In July 2025, the European Space Agency’s Mars Express orbiter captured a high-resolution image of Acheron Fossae, a region marked by deep chasms and ridges on Mars’s surface. These features, created by ancient crustal stretching, split the terrain into raised horsts and sunken grabens. Valley floors reveal smooth surfaces carved by slow-moving, ice-rich rock glac…
