The observable universe is 93,000,000,000 light years wide. Not the full universe. Just the part where light has had time to reach us. Beyond that — we have no idea. It could go on forever. The nearest star to Earth after our own Sun is Proxima Centauri — 4.24 light years away. At the speed of our fastest ever spacecraft, Voyager 1 — it would take 73,000 years to get there. That is our closest neighbour in space. The zoom you just watched started at the outer edge of everything humans have ever observed. It ended at you. And it still didn't show you how big it actually is. 👇 Did the size of the universe ever cross your mind before this? #universe #space #astronomy

The universe is all of space and time[a] and their contents. [9] It comprises all of existence, any fundamental interaction, physical process and physical constant, and therefore all forms of matter and energy, and the structures they form, from sub-atomic particles to entire galactic filaments. Since the early 20th century, the field of cosmology establishes that space and time emerged together at the Big Bang 13.787±0.020 billion years ago [10] and that the universe has been expanding since then. The portion of the universe that can be seen by humans is approximately 93 billion light-years in diameter at present, but the total size of the universe is not known. . . . . #space #universe #interstellar #blackhole #nasa

Explaination 👇 The name "Earth" doesn't come from a single person-it evolved over time from ancient languages. The word comes from Old English "eorbe", which meant ground or soil. It also has roots in Germanic languages (like Old High German "erda"). Unlike most planets (like Mars or Jupiter), Earth is not named after a god. So basically, no one officially "named" Earth-people in ancient times just used their everyday word for the ground they lived on, and it became the planet's name over time.

The definitive 3D map of our universe ✨ On April 15, 2026, the Dark Energy Spectroscopic Instrument (DESI) officially completed its five-year survey of the sky. Perched atop the Nicholas U. Mayall Telescope at Kitt Peak, this instrument uses 5,000 robotic eyes to peer back 11 billion years into our history. These positioners are accurate to within 10 microns, which is less than the width of a human hair, allowing a global team of over 900 researchers to capture light from 47 million galaxies and quasars. Early results suggest that dark energy might not be a “cosmological constant” as previously thought. Instead, there are hints that it could be evolving over time. If confirmed, this would mark a massive shift in our understanding of how the universe expands and its ultimate fate. #fyp #space #astronomy #nasa #universe

For over a century we believed Andromeda was on an unstoppable collision course with our galaxy. Science just said not so fast 🌌 As far back as 1912 astronomers noticed Andromeda heading toward us. By 2012 NASA confirmed it was moving so directly toward us that a collision seemed as inevitable as death itself. The night sky billions of years from now would blaze with newborn stars, two galaxies merging into one giant elliptical structure astronomers already named Milkomeda 🤯 Then in June 2025 everything changed. Astronomers Till Sawala and his team at the University of Helsinki ran 100,000 simulations using the latest Hubble and ESA Gaia data factoring in 22 different variables. What they found shook the astronomy world 🌀 They found only a 2% probability that the galaxies will collide in the next five billion years, contrary to the previous belief that collision was a certainty within that timeframe 💀 The Large Magellanic Cloud, a satellite galaxy of the Milky Way, pulls us perpendicular to Andromeda's path, significantly reducing the chance of merger. A tiny galaxy quietly saving ours without anyone asking it to 🔭 But here is what makes it truly beautiful. If a collision does occur it would trigger a fierce period of star birth followed by intense radiation from exploding young stars and a newly active supermassive black hole. A catastrophe that would simultaneously birth thousands of new suns 💫 A smashup would toss our Sun into a completely new orbit. Stars inside each galaxy are so far apart they would never directly collide. Earth itself would survive, just relocated somewhere entirely new in a galaxy it no longer recognizes 📡 INTERESTING FACT: more precise Gaia telescope data arriving in summer 2026 will refine our understanding of Andromeda's exact speed and direction, potentially changing this prediction once again. We may not know our galaxy's true fate until later this very year ⏳ . . . . . . .

The best geometric example of a 4th dimension is a tesseract (or hypercube), which is a 4D analogue of a cube that appears to morph or "rotate" through 3D space. It consists of eight 3D cubes connected together, where our 3D perception only sees a "shadow" or cross-section changing shape as it passes through our reality. #universe #explore #space #dimensions #cosmos Follow for more @interstellarpage 👈

This is the largest map of the universe ever made This map comes from DESI (Dark Energy Spectroscopic Instrument), a project that’s been scanning the sky for years to build a 3D view of the cosmos. So far, DESI has measured spectra for over 47 million galaxies and quasars, along with more than 20 million stars in the Milky Way — making this the most detailed, high-resolution map of the universe ever created. What looks like scattered dots is actually the structure of the universe itself — galaxies tracing out vast patterns shaped over billions of years.

How Big Is the Universe… Really? 🌌 Bigger than your imagination can handle. Our planet is tiny compared to the Sun. The Sun is tiny compared to the Milky Way. And the Milky Way is just one galaxy among billions in the observable universe. Light — the fastest thing we know — takes over 8 minutes just to reach Earth from the Sun. To cross our galaxy? About 100,000 years. And beyond that… billions more galaxies stretching into the cosmic unknown. You’re not small. You’re part of something unimaginably vast.

The observable universe is estimated to be about 93 billion light years in diameter based on current cosmological models. Because of the expansion of space we can only see a portion of the entire universe and its true size may be far larger or even infinite. This concept is based on the Big Bang and ongoing research in astrophysics that continues to reshape our understanding of space and reality.

Dark energy is getting weaker? This new map shows dark energy might be getting weaker. That’s odd. Every dot you see here is either a galaxy or a special kind of black hole, and there are 47 million in this new 3D map of our universe. It’s uprooting what we thought we knew about dark energy and implying our universe might be headed toward a very different ending than we thought… For more on that, follow along! #science #energy #universe #galaxy #blackhole NOIRlab
