JELLYFISH NEBULA - a supernova remnant sculpted by powerful shock waves moving through dense interstellar gas. IC 443 is the aftermath of a massive stellar explosion that occurred thousands of years ago, with the expanding shock fronts now colliding with surrounding molecular clouds. These violent interactions energize hydrogen, sulfur, and oxygen atoms, creating the complex filaments and stratified color layers that define the nebula’s structure. Its distinctive, jellyfish-like form emerges where the blast wave encounters regions of uneven density, compressing and heating the gas into luminous arcs and clumps. IC 443 is also a notable source of high-energy emission, with strong evidence of particle acceleration and a connection to a nearby neutron star.

A quantum mechanical system behind a barrier can have varying amounts of energy, but it can only absorb or emit specific amounts of this energy. The system is quantised. Tunnelling occurs more easily at a higher energy level than at a lower one so, statistically, a system with more energy is held captive for less time than one with less energy. This year’s #NobelPrize laureates in physics conducted experiments with an electrical circuit in which they demonstrated both quantum mechanical tunnelling and quantised energy levels in a system big enough to be held in the hand.

BREAKING NEWS The Royal Swedish Academy of Sciences has decided to award the 2025 #NobelPrize in Physics to John Clarke, Michel H. Devoret and John M. Martinis “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.”

🌌 Cosmic Mystery Series – Episode 3 The Open Road 🔥 At last… freedom. For tens of thousands of years, I wandered in fire, bouncing endlessly in the Sun’s core and outer layers. And now — in a single instant — I burst through the photosphere, the surface of the Sun, and enter the vastness of space. No more collisions. No more endless wandering. Now I move in a straight line, unbroken, at the ultimate speed limit of the universe: 299,792 kilometers per second. 🚀 To you, this speed is unimaginable. In just one second, I could circle the Earth seven and a half times. To me, though, there is no sensation of time. For a photon, time does not exist. I was born in the heart of a star… and in my own reality, I am everywhere in an instant. --- ☀️ Leaving the Sun From the Sun’s surface, I shoot outward into the Solar System. Behind me, the Sun blazes — a roaring sphere of plasma, so massive that its gravity still tries to bend my path. But I am free now, racing across the open road of space. I am not alone. Billions of photons burst out every second, a continuous flood of sunlight. Together, we are the reason the Solar System glows. But I wonder… who will meet me first? --- 🌍 The Journey to Earth Ahead of me lies a small, blue world: Earth. Distance: 150 million kilometers. Time to reach it: just over 8 minutes. On the way, I pass giants: Mercury, too close to the Sun to hold me; Venus, shrouded in clouds, reflecting me back into space. Then comes Earth — vibrant, alive, unique. I am heading there. Some of my photon brothers will miss, flying past into the endless dark. But I… I am destined for Earth. --- ✨ The Beauty of the Road Space feels empty, but it is alive with secrets. I am bent slightly by gravity as I pass near planets — this is called gravitational lensing, where light curves around mass. Even the Sun behind me bends my siblings’ paths like a cosmic magnifying glass. Asteroids, comets, and dust drift across the path, some blocking a few of us, scattering others. But nothing stops me. The open road is clear. And then, finally, I see Earth — glowing with blues, whites, and greens. A fragile world, suspended in darkness. --- 🔭 Science Note Once photons escape the Sun, they travel in straight lines through space at the speed of light. The Sun–Earth distance is 1 AU (Astronomical Unit) ≈ 150 million km. Light takes 8 minutes 20 seconds to reach Earth. Gravitational lensing: massive objects bend the path of light due to gravity, first predicted by Einstein. In less than ten minutes, I will arrive. I will touch Earth. But where exactly will I land — on a desert, an ocean, or inside your very eyes?

BLOOD MOON ECLIPSE Tomorrow, September 7, 2025, a total lunar eclipse, often referred to as a "Blood Moon" or "Red Moon," will occur. This celestial event will be visible from Europe, Africa, Asia, and Australia. The Phenomenon: Why the Moon Turns Red During a total lunar eclipse, the Earth passes directly between the sun and the moon, casting a shadow on the moon's surface. So why doesn't the moon just disappear into darkness? The answer lies in Earth's atmosphere. The reddish hue is caused by a phenomenon called *Rayleigh scattering*. As sunlight travels through Earth's atmosphere, shorter wavelengths of light, like blue and violet, are scattered away by air molecules. The longer wavelengths, such as red and orange, are able to pass through the atmosphere more directly. This filtered, reddish light is then bent (refracted) and cast onto the moon's surface, making it appear red, orange, or even coppery. The same principle is what makes sunsets and sunrises appear red. The intensity of the red color can vary depending on the amount of dust, volcanic ash, or clouds in Earth's atmosphere at the time of the eclipse. Eclipse Details and Timings This particular eclipse is notable for its long totality, lasting about 82 minutes, and its widespread visibility. Here are the key timings in Indian Standard Time (IST): * Penumbral eclipse begins: 8:58 PM IST * Partial eclipse begins: 9:57 PM IST * Totality begins (Blood Moon): 11:00 PM IST * Maximum eclipse: 11:41 PM IST * Totality ends: 12:22 AM IST (on September 8) * Partial eclipse ends: 1:26 AM IST (on September 8) * Penumbral eclipse ends: 2:25 AM IST (on September 8) How to Watch A total lunar eclipse is completely safe to view with the naked eye. No special equipment is necessary. To get the best view, find a location with a clear, unobstructed horizon and minimal light pollution.

🌌 Cosmic Mystery Series – Episode 2 The Great Escape I am light. A photon. Born in fire, trapped in chaos. For thousands of years, I’ve wandered inside the Sun, bouncing endlessly in every direction. My prison is not made of walls, but of density. The Sun’s core is so crowded with particles that every time I try to move straight, I crash. Electrons, protons, helium nuclei—like a cosmic traffic jam, they shove me in new directions. I am always moving at my ultimate speed, yet my progress is painfully slow. This endless dance is called the random walk. Imagine being in a blinding storm where every step, someone spins you around and pushes you elsewhere. You move constantly but reach nowhere. That’s my life inside the Sun. 💡 To you, it feels impossible. “Light is fast,” you think. Yes, but here I am slowed not by my nature, but by collisions. For me, seconds become centuries. My story stretches across millennia. 🌟 Civilizations rise and fall on Earth while I remain trapped. When I was first born, humans had not yet seen fire. Now, as I inch forward, humans have already built pyramids, cities, telescopes… and one day, they will see me. 🔥 Crossing the Zones Finally, after tens of thousands of years, I reach the edge of the core. I enter the radiative zone — a vast ocean of plasma. Here, my random walk continues, but slowly, patiently, I drift outward. Each collision redirects me, each step measured in centuries. The Sun is unimaginably vast; it would take 1.3 million Earths to fill its volume. And I, a single photon, must crawl through this ocean. But there is hope. Beyond the radiative zone lies the convective zone, a realm of boiling currents. Here, gigantic bubbles of plasma rise and fall like storms larger than Earth itself. These currents grab me, carry me upward, push me closer to freedom. It feels like being trapped in lava lamps the size of worlds. I ride these cosmic currents, tossed and carried, until… 🌅 The Surface There it is. After 100,000 years or more, I finally see light not from within me, but from outside — the faint glow of the photosphere, the Sun’s visible surface. Here, the Sun no longer feels like a prison. Instead, it feels like a gateway. At the photosphere, I can finally break free, no longer trapped by endless collisions. For the first time since my birth, I sense open space. No more random walk. No more chaos. I am about to become what I was destined to be: sunlight. 🔭 Science Note Random walk: Photons scatter billions of times inside the Sun’s radiative zone, making their escape extremely slow. Radiative zone: Energy transfer happens by radiation, photon by photon. Convective zone: Energy is transported by giant plasma motions, like boiling water in a pot. Photosphere: The surface layer of the Sun (about 5,500 °C), where photons can finally escape into space. After tens of thousands of years in fire and chaos, I am finally free. In moments, I will cross the surface of the Sun. And then, for the first time, I will see the universe.
