Yesterday’s Sun: 24 Hours of Solar Activity in 80 Seconds | NASA SDO

Twenty-four hours of the Sun compressed into 80 seconds — captured by NASA's Solar Dynamics Observatory in extreme ultraviolet light (AIA 304Å), revealing the Sun's chromosphere glowing at around 50,000 degrees. In this timelapse from 10 July 2026: 🔆 Active Region 4482 — days ago the most dangerous sunspot group on the Sun, now quietly decaying near disc centre as its magnetic complexity unravels 🌑 Dark filament channels snaking across the northern hemisphere — enormous rivers of cooler plasma suspended by magnetic fields, hundreds of thousands of kilometres long. Just two nights earlier, a filament in this same region violently erupted into space. 🔥 Prominences dancing on the eastern limb — arcs of solar material rising and falling above the Sun's edge ⚡ Active Region 4485 waking up in the west — watch it brighten through the day as it flares and launches a coronal mass ejection (which thankfully missed Earth) All of this happened in one ordinary day on our star, 93 million miles away. ▶ New solar timelapses and space videos every week — subscribe so you don't miss the next big eruption. 📷 Imagery: NASA/SDO and the AIA science team (courtesy of NASA/SDO and the AIA, EVE, and HMI science teams) 🛰 Learn more about the Solar Dynamics Observatory: https://sdo.gsfc.nasa.gov 🌍 Live space weather: https://www.swpc.noaa.gov ⏱ CHAPTERS 0:00 The Sun in extreme ultraviolet 0:10 Active Region 4482 — a giant standing down 0:22 Filaments across the northern hemisphere 0:38 Prominences on the eastern limb 0:52 AR4485 flares in the west 1:08 One ordinary day on our star #Sun #NASA #SolarActivity #SpaceWeather #Timelapse
