Dark matter near the Milky Way’s center appears flattened, not spherical, according to new simulations. The discovery may explain a puzzling gamma-ray glow long observed by NASA’s Fermi telescope, reigniting theories that dark matter collisions produce high-energy radiation in the galaxy’s core

Astronomers have detected a small companion star orbiting the red supergiant Betelgeuse using Hubble and Chandra observations. Dubbed “Betelbuddy,” the discovery reveals an extreme binary system that challenges existing models of stellar evolution and may offer clues to Betelgeuse’s future.

A new Scientific Reports study warns that dimming the Sun with sulfur aerosols could cause severe side effects, including disrupted monsoons, ozone loss, and acid rain. Researchers stress that despite its cooling potential, such geoengineering carries unpredictable global risks that outweigh short-term benefits.

VOV.VN - Trong một bước tiến quan trọng, Google vừa công bố bộ xử lý lượng tử Willow mang đến sức mạnh vô cùng ấn tượng khi so sánh với các siêu máy tính trong quá khứ.

Carnegie Mellon engineers have unveiled AI-controlled drones that 3D print by snapping magnetic blocks together mid-air. Powered by a large language model, the drones translate simple commands into precise construction plans, achieving 90% accuracy. The technology could enable aerial infrastructure repair and emergency shelter construction in hard-to-reach areas.
