Galaxies flying away from us: How Hubble's redshift led us to the Big Bang
On a crisp night in the late 1920s, Edwin Hubble stood in the dome of the 100-inch Hooker telescope at Mount Wilson Observatory, high above the smog and streetlamps of Los Angeles. Through that giant eye, he measured the light from distant 'spiral nebulae' — what we now call galaxies — and found something remarkable. Their light was shifted toward the red end of the spectrum, a sign that they were racing away from us. It was as if the universe itself were stretching. When light from a moving source is stretched to longer wavelengths, we call it redshift — much like the way a passing train's whistle drops in pitch as it moves away. Hubble discovered that the farther a galaxy was, the greater its redshift — meaning the faster it was receding. This became the Hubble–Lemaître law, a simple but revolutionary equation showing that the universe is expanding. But here's the subtlety: the galaxies are not flying through space as bullets through the air. Instead, the space between them is stretching. A common analogy is raisin bread dough rising in the oven — as the dough expands, every raisin moves away from every other raisin, and the farther apart two raisins start, the faster they separate. Crucially, the bread isn't expanding into the kitchen; the dough itself is the 'space.' In the same way, the universe isn't expanding into some empty void — it's the distance scale itself that's growing. This is why galaxies farther away show greater redshift: they're not just distant in space, they're distant in time, and the intervening space has been stretching for billions of years. The implication was staggering: if the galaxies are all moving apart today, then in the distant past, they must have been much closer together. Follow this logic far enough back and you arrive at a moment when all the matter, energy, space, and time we know were compressed into a single, unimaginably dense point. The first to put this into words was Georges Lemaître, a Belgian priest and physicist. In 1931, he proposed that the universe began from a 'primeval atom' — an idea that would later be nicknamed the Big Bang. At the time, the name was meant to be dismissive; British astronomer Fred Hoyle, along with his student and celebrated Indian astrophysicist Jayant Narlikar, champions of the rival Steady State theory, coined it in a radio broadcast to mock the idea of a cosmic explosion. Ironically, the label stuck and became the most famous phrase in cosmology. For decades, the debate raged: was the universe eternal and unchanging, or did it have a beginning? The tie was broken not in an ivory tower, but in a New Jersey field. In 1964, Arno Penzias and Robert Wilson, two engineers at Bell Labs, were testing a radio antenna for satellite communications when they picked up a persistent hiss of microwave noise. They cleaned the antenna, even shooed away nesting pigeons — but the signal stayed. Unbeknownst to them, just 50 km away, Princeton physicist Robert Dicke and his team were preparing to search for the faint afterglow of the Big Bang. When the groups connected, the truth emerged: Penzias and Wilson had stumbled upon the cosmic microwave background (CMB), the fossil light from the universe's infancy, released about 380,000 years after the Big Bang. The CMB confirmed that the universe had indeed begun in a hot, dense state and has been cooling and expanding ever since. In the first fraction of a second, an incredible burst of inflation stretched space faster than the speed of light. This expansion wasn't into anything — rather, the very fabric of space itself was stretching, carrying galaxies along with it. As space grows, so does the distance scale we use to measure it: a galaxy whose light left billions of years ago was much closer then than it is today. That's why the farther away we look, the greater the redshift we see — we are peering not just across space, but back in time, to when the universe was smaller. The CMB is the afterglow from a time about 380,000 years after the Big Bang, when the universe had cooled enough for electrons and protons to form neutral atoms, letting light travel freely for the first time. That light has been on a 13.8-billion-year journey to us, its wavelength stretched by cosmic expansion from the fierce glare of the early universe into the faint microwave glow we detect today. Over the next minutes after the Big Bang, nuclear fusion forged the first elements: hydrogen, helium, and traces of lithium. Hundreds of millions of years later, the first stars and galaxies ignited, manufacturing heavier elements in their cores and seeding the cosmos with the building blocks of planets and life. Billions of years on, our Sun and Earth formed from recycled stardust, and here we are — creatures of carbon, contemplating the birth of time. The Big Bang theory is not just an origin story; it's a framework that explains everything from the cosmic web of galaxies to the faintest ripples in the CMB. It predicts the abundance of light elements, the distribution of galaxies, and the universe's large-scale geometry. Without it, we'd have no coherent picture of cosmic history. Today, the expansion first seen by Hubble is still ongoing — in fact, it's accelerating, driven by the mysterious dark energy. The latest measurements from telescopes like Hubble's successor, the James Webb Space Telescope, and surveys like the Sloan Digital Sky Survey continue to refine our understanding of the early universe, probing the first galaxies that emerged from cosmic darkness. The journey from a lone astronomer squinting at galaxies to a global scientific collaboration mapping the cosmos is a reminder that big ideas often start with small clues. As Carl Sagan once put it, 'We are a way for the cosmos to know itself.' The Big Bang is not just about how the universe began — it's about how we began, too.

Top 10 never-before-seen breathtaking pictures clicked by Webb Telescope
Top 10 never-before-seen breathtaking pictures clicked by Webb Telescope 13 Aug, 2025 Credit: Nasa Webb's newest look at NGC 6072 reveals an unusual, asymmetrical scene, potentially caused by a binary star system (two stars orbiting one another). In this picture of Cat's Paw Nebula, the active star-forming region is revealing more about how young stars are shaping the surrounding gas and dust. This new mosaic combines Webb's observations with NASA's Hubble Space Telescope's, increasing our understanding of open star clusters NGC 460 and NGC 456. Open star clusters are made up of dozens to thousands of stars held loosely together by gravity. This galaxy, called Messier 82 (M82) or the Cigar Galaxy, is smaller than our Milky Way, but 5x as luminous and forms stars 10x faster! Its fast rate of star formation classifies M82 as a starburst galaxy. NASA's James Webb Space Telescope captured the central region of the Bullet Cluster with its NIRCam (Near-Infrared Camera). The scene contains two massive galaxy clusters that sit on either side of the large, light blue spiral galaxy at the center. Deep in this Webb image are little green galaxies, and they're possibly the cause of an extreme cosmic makeover. For its first billion or so years, the universe was immersed in a fog of neutral hydrogen gas. Webb captured this image, showing the iconic Sombrero galaxy in near-infrared light for the first time. In November 2024, Webb took a look at this galaxy in mid-infrared, adding to the Hubble Space Telescope's visible light view. These observations of Jupiter's auroras at 3.36 microns (F335M) were captured with NASA's James Webb Space Telescope's NIRCam (Near-Infrared Camera. Webb is "running rings" around this planetary nebula, NGC 1514, bringing it into sharp focus with this new mid-infrared look. At the center are a pair of stars, one of which shed its layers of dust and gas as it neared the end of its life cycle. This outflow from a newly forming star gives this Herbig-Haro object (HH 49/50) its nickname, the 'cosmic tornado.' This pillar of gas and dust looks like it's topped by a galaxy.

Will an astronomical anomaly challenge the idea of scientific revolutions?
Before the revolution triggered by Nicolaus Copernicus, a 16th-century cleric, the Earth was the unmoving centre of the cosmos. Afterwards, it was one of a family of planets swinging through space. Before the work of Antoine Lavoisier, an 18th-century nobleman, chemists had no notion of 'oxygen', 'carbon' and the like; afterwards they could not understand the contents of their alembics without them. Such examples are at the heart of the idea, put forward in the 1960s by Thomas Kuhn, of the paradigm shift. Such shifts, he argued, did not just involve a new theory explaining the world better than an old one; they required a change in the sort of entities the world was thought to be made up of. In a way that seems almost self-exemplifying, the idea provided a new way of looking at science itself: not as one thing, but two. In the 'normal' phase scientists applied their physical and conceptual tools to problems the scope of which was pretty well understood; in revolutionary phases, paradigms shifted. Normal didn't mean dull or unimportant. When, in the 1980s, American astronomers made the case for the Hubble Space Telescope, then the costliest scientific instrument in history, none of its goals mattered more than what seemed a perfect example of normal science: nailing down the value of the constant (also named after Edwin Hubble, an astronomer) which says how fast the universe is expanding. The Hubble did this very well. The difficulty, as our Science section reports, is that since its launch it has become possible to estimate the Hubble constant on the basis of background radiation from all over the sky, rather than distances to individual objects. And these new estimates are significantly lower. The seemingly unbridgeable divide between the approaches has become known as the Hubble tension. To those who know their Kuhn this looks like the sort of anomaly that might precede some new paradigm shift. The possibility is tantalising. The conceptual usefulness of paradigm shifts has been much debated, as indeed has their existence. The concept is horribly overused. (A new paradigm for vegan cosmetics!) Yet the notion of a fresh worldview remains dramatic and beguiling, and the romance only increases when it applies on a cosmic, but reassuringly inconsequential scale. (A paradigm shift in financial markets might be far more practically important.) The problem is that, as Kuhn noted, you can judge these things only in retrospect. The sort of anomaly that is recast and solved by a paradigm shift is not in principle distinguishable from a 'normal' problem which has not yet been solved. The paradigms in which normal science is done are, like the fabric of the universe, somewhat stretchy; new ideas, sometimes quite big ones, can be incorporated without wholesale change. And some suspect that science's capacity to adapt itself in this way has increased since the days of Kuhn's examples. It is far more institutionalised and regimented today, and that may provide a stability, even a rigidity, to its worldviews. This need not be a bad thing. Paradigm shifts are not necessary for technological improvement. But it is hard not to think that, if their age has gone, then so has some of science's thrill—and hard not to want the Hubble tension to demonstrate that paradigms can still be pulled apart.
