When a meteor speeds into Earth’s atmosphere, it lights up due to intense friction with the air—generating extreme heat. That heat makes the meteor glow, but here's the cool part: the color of that glow tells us what it's made of! Just like fireworks, different elements shine in different colors when heated. As the meteor blazes through the sky at tens of kilometers per second, atoms in both the meteor and the surrounding air get excited—and they release light in specific wavelengths. The result? A fiery, colorful display that reveals the meteor’s chemical makeup. #MeteorShower #SpaceScience #WhyItGlows #AstroFacts

Astronomers are raising alarms over SpaceX’s Starlink satellite constellation, which is leaking unintended radio signals that could severely interfere with cosmic observations. While Starlink satellites are designed to beam internet across the globe, researchers have discovered that these spacecraft are also emitting low-level radio frequencies outside their intended transmission bands. This unintentional leakage could hinder the ability of radio telescopes to detect faint signals from the early universe, effectively masking some of the oldest and most distant cosmic phenomena. Despite SpaceX’s efforts—like disabling signal beams over major observatories—the growing swarm of satellites continues to pose a challenge. With over 6,000 Starlink units already in orbit, and tens of thousands more planned, the scale of potential interference is massive. This issue underscores a rising conflict between tech innovation and scientific exploration, sparking urgent calls for stronger regulations and international coordination to protect the integrity of space-based astronomy. #Starlink #AstronomyThreat #RadioInterference #SpaceScience #ProtectAstronomy

China is once again shaking up the world of astronomy — this time with a colossal 120-meter mobile radio telescope, reportedly under construction in Jilin. Unlike traditional static telescopes, this one can move and track objects across the sky in real-time, offering astronomers far more flexibility in deep-space exploration. But that’s not all. This mega-telescope joins a growing network of 24 smaller 40-meter telescopes being installed across China, many of which support or complement the already-operational FAST (Five-hundred-meter Aperture Spherical Telescope) — the world’s largest stationary radio dish. Together, these telescopes will allow China to detect faint signals from the farthest reaches of the cosmos, search for exoplanets, track asteroids, and even send calibrated signals to space with unprecedented accuracy. While many countries scale back budgets, China is building the future of space science — one giant dish at a time. #ChinaTelescope #FASTTelescope #RadioAstronomy #SpaceExploration #DeepSpaceScience
