Inside Science on Instagram: "Detected in 2025, 3I/ATLAS is an interstellar object — a traveler from beyond our solar system — now racing past the Sun on a hyperbolic path. But recently, astronomers picked up something unusual: repeating radio pulses coming directly from its direction, echoing in a precise pattern — 8, 13, 8, 5, 13, 8 — all transmitted at 1420 MHz, the “cosmic hailing frequency” famously used in SETI searches for intelligent life. #3IATLAS #InterstellarVisitor #CosmicSignals #SE

Inside Science on Instagram: "🏹 Why the Horizontal Speed of a Projectile Never Changes Follow @inside_science_ for daily insights that make physics come alive ⚙️ When you launch a ball, an arrow, or even a rocket, its motion splits into two independent parts — horizontal and vertical. The horizontal speed (velocity along the x-axis) stays constant throughout the flight, as long as air resistance is ignored. That’s because once the projectile leaves your hand, no external horizontal force acts o
