New telescope images show interstellar comet 3I/ATLAS ejecting a giant jet of gas and dust toward the Sun. Scientists say the phenomenon confirms its natural cometary behaviour, offering clues about how such ancient interstellar visitors react to solar heat.

NASA’s Europa Clipper spacecraft may soon pass through the ion tail of interstellar comet 3I/ATLAS, offering a rare opportunity to sample material from beyond our solar system. Scientists say this encounter could yield valuable insights into the formation and evolution of star systems.

A new super-Earth, GJ 251 c, has been found orbiting a nearby red dwarf star within its habitable zone. About four times Earth’s mass, it may host liquid water. Detected via the radial-velocity method using Penn State’s Habitable Zone Planet Finder, it’s a prime target in the search for life.

Fossils from New Mexico’s San Juan Basin, dated to just 350,000 years before the asteroid impact, prove dinosaurs remained diverse and abundant until their sudden extinction. The study debunks the belief they were fading beforehand, showing a vibrant Late Cretaceous ecosystem teeming with hadrosaurs and sauropods.

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.

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.

Semi-transparent solar cells are reshaping renewable energy in urban environments. Developed by Hong Kong Polytechnic University, these ST-OPVs reach 6.05% efficiency and can be integrated into windows and facades without affecting natural light.

Analysis of Chang’e-6 lunar dust uncovered microscopic carbonaceous chondrite fragments—evidence of water-bearing asteroids that once struck the Moon. The discovery indicates a far greater delivery of water and organics to Earth and the Moon than thought, helping scientists refine theories about the solar system’s early volatile sources.

Using JWST data, astronomers analyzed more than 250 galaxies from the universe’s first 1.5 billion years and found most were chaotic, with gas swirling in all directions. Only a few showed early signs of ordered rotation. The findings reveal how intense star formation and gravitational turbulence gave way to stability, transforming the early universe’s cosmic […]
