The Solar System will stay stable for at least 100 billion years—far longer than Earth itself! Key Takeaways: Scientists estimate that a close stellar flyby capable of destabilizing the Solar System won’t happen for another 100 billion years. Even when a star does pass nearby, it’s still unlikely to disrupt the planets’ orbits significantly. Using…
A 4.6-billion-year-old meteorite contained 11% extraterrestrial water, linking asteroids to Earth’s oceans. Key Takeaways A 4.6-billion-year-old meteorite crash in the UK provided evidence that Earth’s water came from asteroids. Scientists confirmed that the water in the Winchcombe meteorite closely matches Earth’s water composition. The meteorite, recovered just hours after landing, is one of the most…
Voyager 1, traveling at 35,000 mph, will take 80,000 years to reach Proxima Centauri. Key Takeaways: Humanity has sent probes beyond the Solar System, but interstellar travel remains out of reach. Even the fastest spacecraft would take tens of thousands of years to reach another star. The vast distances between stars make conventional rocket travel…
A stellar engine could move the entire solar system—traveling 50 light-years in a million years! Key Takeaways: An astrophysicist has envisioned a stellar engine capable of moving the entire solar system. The concept, explored in a Kurzgesagt video, suggests using the Sun’s energy as propulsion. The Shkadov Thruster is a passive solar sail, but it…
Mars’ ancient lakebed holds carbon clues, hinting at unexpected organic processes in its past. Key Takeaways: NASA’s Curiosity rover found organic matter on Mars with unusual carbon isotope ratios, challenging past assumptions. The discovery suggests Mars’ surface may contain more organic material than scientists previously believed. Laboratory experiments indicate that non-biological atmospheric processes likely created…
NASA’s AI just confirmed 301 new exoplanets—without the need for human verification. Key Takeaways: NASA has confirmed 301 new exoplanets, significantly expanding the known list of worlds beyond our solar system. The discoveries were made using ExoMiner, an AI-driven program that analyzes vast amounts of data. ExoMiner is more reliable than human classification, reducing the…
A cosmic radio burst carried more energy than the Sun produces in 30 years. Key Takeaways: A fast radio burst (FRB) traveled 8 billion years before reaching Earth—the farthest ever detected. The signal, lasting less than a millisecond, released energy equal to 30 years of sunlight. Astronomers believe magnetars—ultra-magnetic neutron stars—are the likely source of…
WASP-121b is so hot (4,600°F) that iron and magnesium escape into space. Key Takeaways: Hubble discovered a football-shaped exoplanet, WASP-121b, leaking heavy metals like iron into space. This is the first time astronomers have seen heavy metals escaping a planet’s atmosphere. WASP-121b’s extreme heat (4,600°F) makes it puff up, weakening its gravity and causing material…
No matter their size, all disk galaxies take about a billion years to spin once. Key Takeaways: Astronomers discovered that every disk galaxy—big or small—completes one full rotation in a billion years. This finding suggests a fundamental, clock-like mechanism governing galaxy rotation across the universe. Researchers unexpectedly found older stars at the edges of galaxies,…
Astronomers found a Sun-like sibling, HD186302, 184 light-years away—could it host another Earth? Key Takeaways: Scientists discovered HD186302, a star nearly identical to the Sun, located 184 light-years away. This is only the second known solar sibling, the first being HD 162826, discovered in 2014. The Sun was born in a massive stellar nursery, but…
