A Planet with Two Suns… and Endless Sandstorms! Meet VHS 1256 b — a mysterious, fiery world located just 70 light-years away, orbiting a pair of stars. Thanks to the James Webb Space Telescope, we now know this isn’t your typical exoplanet—it sits right on the edge between a giant planet and a brown dwarf. Temperatures? Around 830°C (1,526°F). Weather? Non-stop silicate sandstorms raging across its skies. JWST's powerful instruments detected a mix of methane, carbon monoxide, water, and even signs of carbon dioxide—the most molecules ever detected at once in a single alien atmosphere! Its skies are chaotic: Heavy silicate grains sink back down. Lighter particles ride up. This vertical dance creates wild brightness swings over its 22-hour day—like watching an alien sunset on fast-forward. And because VHS 1256 b orbits far from its two stars, its light can be studied in isolation, giving astronomers an unfiltered view of its dynamic, dusty atmosphere. But the biggest mystery? Did it form like a planet—or like a star? We still don’t know. RESEARCH PAPER: Brittany E.

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

Meet BD+05 4868 b — one of the most extreme exoplanets ever found. Located 140 light-years away, this scorching world orbits its star every 30.5 hours, putting it 20 times closer than Mercury is to our Sun. At that range, the heat is so intense it’s vaporizing the planet’s rocky surface, creating a dust tail over 9 million kilometers long — nearly half of its orbit! Nicknamed the “melting Mercury”, this tiny planet is losing mass fast — about the size of Mount Everest every orbit. With weak gravity and a shrinking core, scientists believe the planet could completely vanish within 1 to 2 million years. But there’s a silver lining: this doomed planet’s dusty trail gives astronomers a rare chance to study the interior makeup of a rocky exoplanet — potentially unlocking secrets of how planets form and what makes them habitable.

Scientists have discovered that polymetallic nodules—rock formations found across the deep ocean floor—can generate oxygen through a surprising chemical process. Without needing sunlight, these nodules produce tiny electric currents that split water molecules into hydrogen and oxygen, essentially mimicking electrolysis in complete darkness. This process, known as "dark oxygen" production, reveals that life in the ocean’s abyss might not rely solely on surface-driven photosynthesis. It also raises exciting prospects for finding life on oceanic exoplanets like Europa or Enceladus, where sunlight can’t reach but minerals and water might interact in similar ways. #DeepSeaDiscovery #DarkOxygen #OceanScience #Astrobiology #DeepOceanRocks

Jupiter may look like a giant ball of hydrogen and helium—but its insides tell a far more dramatic story. Thanks to NASA’s Juno mission, scientists have discovered that Jupiter holds up to 30 Earth-masses of heavy elements buried deep inside. And they’re not spread out evenly—they’re clumped near the core, shaking up everything we thought we knew about how gas giants form. Instead of growing slowly by collecting space dust and pebbles, Jupiter likely feasted on massive rocky planetesimals—the very building blocks of planets—before gulping down gas from the solar nebula. These weren’t just snacks… they were entire baby planets. And there’s more: the unexpected distribution of metals suggests that Jupiter’s interior isn’t churning like boiling water as once believed. That changes how we model giant planets—not just in our Solar System, but across the galaxy. With telescopes like James Webb peering at distant worlds, this discovery could mean we’ve been underestimating what exoplanets are really made of. Jupiter isn’t just a planet—it’s a cosmic time capsule. 📄 Source: Y. Miguel et al., “Jupiter’s Inhomogeneous Envelope,” A&A (2022)
